Foraging activity of the honeybee (<em>Apis mellifera</em> L.) in pollen collection were studied during spring and summer, 2012. The quantity and quality of the collected pollen were investigated.
The obtained results showed that over spring and summer seasons, the highest amount of trapped pollen (240.07 gram/colony/week) were recorded on August, when temperature was 35.02<sup>◦</sup> C and relative humidity was 52%, however the lowest amount (13.38 gram/colony/week) was in April with temperature of 25.42<sup>◦</sup> C and relative humidity 51%.
Concerning foraging activity of the experimental bees over the day, the results showed that the highest amounts of trapped pollen was recorded in the period between 10-12 a.m with average 11.22 g./colony represented 30.31%of the total pollen collected over the day ,followed by the period between 8-10 a.m with average 9.39 g./colony represented 25.36% . While the lowest amount of the collected pollen was found in the period between 4-6 p.m with average 2.61 g./colony which represented 7.04% of the total collected pollen.
On the other hand, results revealed that there were 13 different floral sources of pollen over the two seasons at the region of the study, where bees collected pollen of <em>Zea mays</em> by the highest percentage (46.79%), followed by <em>Trifolium alexandrinum</em> (30.68%), then <em>Phoenix dactylifera</em> (19.00%), however <em>Cucurbita pepo</em> recorded the lowest percentage (1.44%) of the total collected pollen.
Concerning the effect of beebread components on production of the brood area, results indicated to increasing the content of crude protein and crude lipids of the stored beebread was associated with increasing of the brood area in spring, however in summer the brood area decreased with decreasing the crude protein and moisture.
Chemical analysis of the trapped pollen showed that pollen of <em>Helianthus annus</em> recorded the highest level of moisture, crude protein, ash, reducing sugar and pH, while <em>Phoenix</em><em> dactylifera</em> pollen recorded the highest amount of crude lipids and the lowest amount of ash and pH.

In the present work newly hatched larvae of Pink bollworm, <em>Pectinophora gossypiella </em>(Saund.) were fed on diet treated with LC<sub>50</sub> of four compounds two IGR's, chromafonozide 80% & diflubenzeroun48% and two oils super misrona (mineral oil) & linseed oil( botanical oil) to investigate their toxicity, biological aspects and the biochemical impactsin full grown larvae<strong>.</strong>
Obtained results show that the tested compounds affected the PBW larvae by increasing larval and pupal duration, total immature stages, pre oviposition, oviposition and post oviposition period, on contrary these compounds decrease weight of larvae and pupae, longevity of females and males, fecundity of females (total laying eggs/♀) and the percentages of egg hatchability than untreated ones. In addition ,the biochemical analysis revealed that the tested compounds, Chromafonozide, Diflubenzeroun, mineral oil and linseed oil when used at LC<sub>50</sub> values caused significant reduction in soluble protein ,total lipids and ALT and AST content in adult which caused inhibition and/or reduced the reproductive potentiality compared to control.

The susceptibility of the 4<sup>th</sup> larval instar of the laboratory strain of <em>Helicoverpa</em><em> armigera</em> (Hubner) to Abamectin efficiency was evaluated by using different techniques; i.e., dipping, surface film and immersion methods of technique. Abamectin was bio-assayed after 24, 48 72 and 96 hours from the treatment for each technique. The obtained results revealed that the order of the efficiency of the product used against the tested larvae was the same at both LC<sub>50</sub> and LC<sub>90 </sub>values<sub>. </sub>The highest efficiency of Abamectin for dipping technique was attained 96 hours. The corresponding LC<sub>50</sub> and LC<sub>90</sub> values were 51.76 and 93.78 ppm, respectively, while, the lowest efficacy of the product was pronounced at 24 hours, the corresponding LC50and LC<sub>90</sub> values were 93.51 and 236.71ppm, respectively. Whereas the biological activity of the compound against the 4<sup>th</sup> larval instar fed on treated leaves for 48 and 72 hr. occupied middle situation among its efficiency at 24 and 96 hr. The corresponding LC<sub>50 </sub>and LC<sub>90</sub> values of the tested biocide after 48 hrs., were 81.52 and 214.46 ppm. On the other hand these values after 72 hr. of feeding were 69.92 and 119.15 ppm, respectively. The susceptibility rates of the 4<sup>th</sup> larval instar to abamedtin toxicity at LC<sub>50</sub> and LC<sub>90 </sub>values were185.93 & 421.34, 135.34 & 378.25 , 114.66 & 211.64 and 95.58 & 124.29 ppm for surface film technique and 114.73 & 257.19 & 91.32 & 188.65 & 81.56 & 151.15 and 60.58 & 101.19 ppm for immersion method respectively. On the other hand, the susceptibility index as well as the potency levels at both LC<sub>50</sub> and LC<sub>90 </sub>values increased with increasing the period determination .The latent effects of Abamectin on the pupation as well as the adult emergence was determined. The corresponding EC50 and EC<sub>90</sub> values associated to quantal scoring of pupation due to dipping surface film and immersion bioassay were 2.63 & 120.51 , 82.02 & 198.12 and 45.45 & 137.42 ppm respectively. Whereas the corresponding IC<sub>50</sub> and IC<sub>90</sub> values for inhibition of the adult emergence were 20.14 & 91.02, 74.12& 136.22 and 43.22 & 101.32 ppm respectively.

An experiment was carried out under field conditions at Ziton village in Beni-Sueif Governorate during two successive seasons, 2011-2012 and 2012-2013 to choose the suitable time of insecticide applications and their effect on <em>T. tabaci</em> infestation on garlic plants and resultant yield. The four tested treatments by applying two recommended insecticides at different times of plant growth were Carbosulfan (Marshal 20% EC with recommended rate 200 cm<sup>3</sup>/ fed.) and Spinetoram (Radiant 12% SC with recommended rate 120 cm<sup>3</sup>/ fed) compared with the untreated garlic plants.
Results and their statistical analysis showed clearly that all treatments significantly decreased the population density of <em>T. tabaci</em> and increased the garlic yield comparing with control treatment. The applying of Carbosulfan and Spinetoram at 15 day intervals (12 times of applications) throughout the whole growing season of garlic plant till one month before harvesting (T1) lead to reduce the population density of <em>T. tabaci</em> infesting garlic plants and gave the highest yield in the two studied seasons, as an average head weight of 12463.50 kg / feddan. Although, garlic plants which treated by Carbosulfan and Spinetoram after one month of sowing date from Nov., 1<sup>st</sup> at 30 old days till Dec., 15<sup>th</sup> (4 times of applications) (T2) infested by higher number of <em>T. tabaci</em>,then gave the considerable head yield (9313.50 kg / feddan).
However the application of T3 (Spraying of Carbosulfan and Spinetoram from Jan., 1<sup>st</sup> of at 90 old days till Feb., 15<sup>th</sup>) and T4 (spraying of Carbosulfan and Spinetoram from March 1<sup>st</sup> at 150 old days till April, 15 <sup>th</sup>) (4 times of applications) were the lowest infested group of <em>T.tabaci </em>and gave the lowest yield in the 4 insecticide applications, as the average of garlic head weight in the two seasons were 8498.70 and 8333.85 kg / feddan respectively. On the other hand, garlic plants in control plots infested by the significantly highest number of <em>T. tabaci</em> and gave the lowest yield when compared with the fourth treatment, as the average head weight in the two seasons was 6139.35 kg / feddan. Concerning the net return of the all tested treatments, T1 gave the best return 13322.55 L.E / feddan.

Three insecticides; Selecron, Trebon and Patron were sprayed using Knapsack motor sprayer Cifarilli (20 L./Fed.) and Economy Micron ULVA (15 L./Fed.) in cotton field infested with the cotton spiny bollworm <em>Earias insulana</em> (Boisd.) larvae during 2014 cotton season at Qaha district, Qalyoubia Governorate. The spectrum of droplets size ranging between 140-169 microns (VMD) with sufficient number ranging from 14-276 droplets/cm². The productivity of motor sprayer Cifarilli was 12 Fed./day. It was the best equipment, but the lowest productivity was 3.04 Fed./day by using Economy Micron ULVA. Results indicated that Trebon and Selecron insecticides were almost behave to be equitoxic effective in controlling larvae of cotton bollworm on cotton plants than the Patron insecticide with Economy Micron ULVA (15 L./Fed.) followed by Knapsack motor Cifarilli sprayer (20L./Fed.). The efficiency of the tested insecticides could be descendingly arranged as follows: Trebon, Selecron and Patron. The corresponding general reduction rates were 91.15, 55.99 and 92.51% in case of using Micron ULVA equipment and 91.13, 55.19 and 92.20% in case of using Knapsack motor Cifarilli sprayer, respectively. Data showed that, low volume spraying may be recommended because of reducing the time lost in the process filling the machines of reducing the time lost of the spray solution on the plant leaves and saving the lost spray via run off on the ground.

Laboratory trials were carried out to evaluate the influence of seven plant oils on population of two-spotted spider mite <em>Tetranycus urticae </em>Koch (Acari: Tetranychidae) at 30±1<sup>ₒ</sup>C and 70% ±5 RH. The tested plant oils were <em>Jatropha curcas</em> (Jatropha), <em>Eucalypts globulus</em> (Camphor), <em>linum vsitatissimum</em> (Flax or Linen), <em>Ricinus communis</em> (Castor),<em> Rophanus sativu</em>s (Radish)<em>, Lupinus termis</em> (Lupine) and<em> Alilum sativum </em>(Garlic). The amounts of plant oils applied were 3, 4, 5, 6, 7, 8, 9 and 10ml. /liter. and sodium laurel sulfate (S.L.S) and Twen80 were used as solvents. The results revealed that, the Jatropha oil was the highest affective oil on the adult females of<em> T. urticae</em> in comparison with other six oils. The concentrations 8, 9 and 10ml. /l. gave high reduction percentages than the low concentrations for all plant oils. All oils were more effective after 72h. from spraying at high concentration. The S.L.S solvent was more effective than Twen80 and other seven tested oils at all concentrations.

The present study was conducted in the laboratory to assess the effects of two plant extracts (<em>Jatropha curcas </em>& <em>Euphorbia lathyris </em>) with four solvents (chlorophorm, ethyl acetone, acetone and methanol) on eggs and adult females of <em>Tetranychus urticae</em> Koch (Acari : Tetranychidae) at laboratory condition (27±2°C and 65±5% RH.). The results revealed that, the <em>Jatropha curcas </em>and <em>Euphorbia lathyris </em>gave high effected at concentrations 2.4 and 1.2% after 24, 48 and 72h. for adult females of <em>T. urticae</em>. While at concentration, 0.6% gave good results after 72 h. for the two extracts. Also, the concentration of 0.3% was not effective, except for <em>J. curcas</em> when used the acetone as a solvent. The acetone was the best solvent followed by chlorophorm and ethyl acetate. But, the solvent of methanol was not effective for the two plant extracts. The extract of <em>J. curcas </em>was more effective on eggs of<em> T. urticae</em> than the extract of <em>E. lathyris</em>; and the concentration of 2.4% was the best for its effect on eggs. However, the concentrations of 0.6 and 0.3% were slightly effective on eggs of <em>T. urticae.</em>

Wheat (<em>Triticum aestivum</em>) is being attacked by several fungal pathogens, many of them are seed-borne, infesting wheat seeds (grains) are detected by methods as recommended by the ISTA, 1966. Fungi such as <em>Altenaria alternate</em>, <em>Aspergillus flavus, Aspergillus niger, Chaetomium </em>spp<em>, Cladosporium </em>spp<em>, Epicoccum </em>spp<em>, Fusarium </em>spp<em>, Fusarium oxysporum, Fusarium solani, Nigrospora oryzae, Penicillium </em>spp<em>, Rhizoctonia solani, Stemphyllium </em>spp.and<em> Trichoderma </em>spp. were isolated from the wheat cultivars i,e Gemmiza 7, Gemmiza 10, Sids 1, Sids 12, Sakha 93, Sakha 94 and Bani sweif 1. Extracts of pomegranate, Neem and Garlic were screened for the potential antimicrobial activity through cup-plate method against three fungi (<em>F. oxysporum, R. solani </em>and <em>A. alternata</em>. All extracts showed inhibitory activites. <em>F. oxysporum, R. solani </em>and <em>A. alternata</em> were the greater portions of the isolated fungi. <em>In vitro</em> studies, seed treatment with 10, 20 and 30 % of concentration of plant extracts for 24 hours showed a complete germination and all seed testing. <em>In vitro</em> studies using cup-plate method were exercised to examine the antifungal activity of three plant extracts i.e., Neem, Pomegranate and Garlic against such fungi associated with wheat seed. <em>F. oxysporum</em>, <em>R. solani</em> and <em>A. alternata</em> were the greater portion of the isolated fungi. However, they were regarded of our main concern in order that they were known of their serious pathogens. Neem leaf extract showed good activity followed by pomegranate peeland garlic leaf extracts.<em> In vivo</em> trials, results of the efficacy of plant extracts against the seed-borne pathogens were just about those cropped up <em>in vitro</em> practises.
Effect of fungicides (Rizolex T 50 %) and three plant extracts on the incidence of seed-borne fungi and their effect on seed germination were evaluated. The seed treatment by the fungicides showed that (Rizolex T 50 %) increased the germination percentage and reduced seed mycoflora. Fungal properties of plant products were tested. Efficacy of biocontrol agent against (<em>F. oxysporum, R. solani</em> and <em>A. alternata</em>) was found good in controlling the seed-borne fungi and pomegranate was proved to be good inhibitor of fungi associated with wheat seeds. Thus, the seeds should be treated invariably by less phytotoxic fungicides like Rizolex T 50% and biocontrol agent like Pomegranate to eliminate the seed-borne mycoflora of wheat. The main aim of present study is to ascertain the fungal species and their effect on wheat grains germination.

Pomegranate peel powder and its extract were used to study their efficiency against damping-off disease caused by <em>Fusarium oxysporum</em> f. sp. <em>lycopersici</em>. <em>In vitro</em>, methanolic extract of pomegranate peel caused inhibitory effect to the linear growth of different phytopathogenic fungi isolated from different hosts including:
<em>Botrytis cinerea, Colletotrichum dematium, F. oxysporum, F. solani, Phoma </em>sp. and<em> Rhizoctonia solani. </em>Also, Pomegranate peel extract (PPE) effectively decreased linear growth and spore germination of <em>F. oxysporum </em>and greatest decrease was recorded at 4000 ppm under greenhouse conditions. Application of pomegranate peel powder as seed treatment or soil treatment deceased pre and post-emergence damping-off caused by <em>F. oxysporum</em> f. sp. <em>lycopersici</em> compared with untreated infected control. Treating tomato seedlings or soil with peel extract before sowing provided a good protection against damping off and soil treatment was more effective than seedling treatment. Methanolic extract of pomegranate peel revealed that it contained different compounds of antifungal activity including three flavonoids, three tannins, four phenolic compounds, one glycosides along with four sterols.

The present investigation was carried outin the apiary yard at El Kharga Oases, New Valley Governorate, Egypt, during the period extended from January to December 2011. The results of the study reveal that The highest percentages of pollen collectors (28.12 and 14.3%) were recorded during May and September, respectively. The lowest percentages, 3.12 and 2.85%, were noticed throughout February and June, respectively. Maximum number of pollen collectors was noticed during the period from 11 a.m. to 1 p.m. (0.23 bees/ 2 min. / colony). Minimum number of pollen collectors was noticed during the period 7 - 9 a.m. (0.13 bees/ 2 min. /colony). The highest amount of pollen (810 gm. / colony) was collected during May, followed by September (412 gm. / colony). The lowest amount of pollen (82 gm. / colony) was collected during June, followed by February and December (90 and 93 gm. / colony), respectively.Significant correlation were detected between temperature daily range and the average amounts of pollen collection, where, r= 0.310.Highly significant correlation were detected between relative humidity (R.H. %) and the average amounts of pollen collection (gm./colony/ 2h.), where, correlation coefficient (r) = - 0.405.Species composition of collected pollen loads by honeybee workers appeared that, there are 20 different floral sources in El Kharga Oases.Such information will be useful for improving honeybee colony status and development in New Vally especially during the pollen shortage periods.

Field experiments were carried out at El-Ghorieb village, Sahel Selem district, Assiut Governorate during two growing successive seasons, 2013 and 2014 to study some ecological aspects of some piercing sucking pests and associated natural enemies inhabiting water melon, <em>Citrullus vulgaris</em> (Schard).
Results indicated that the major piercing sucking pests [the two-spotted spider mite, <em>Tetranychus urticae</em> Koch; the whitefly, <em>Bemisia tabaci</em> (Genn.); the cotton aphid, <em>Aphis gossypii</em> Glover and the leafhopper, <em>Empoasca decipiens</em> (Paoli)] and their associated natural enemies [<em>Coccinella undecimpunctata, Chrysopa carnea, Orius</em> sp. and <em>Scolothrips longicornis</em>]
Data showed that the relation between the natural enemies with their preys was positively and significantly during both seasons.
The results also showed that the highest dominance and abundance were recorded with the piercing sucking pests; <em>T. urticae</em> and <em>B. tabaci</em> followed by <em>E. decipiens</em> and <em>A. gossypii</em> as for the natural enemies; <em>S. longicornis</em> followed by <em>Orius</em> sp., <em>C. undecimpunctata</em> and <em>Ch. Carnea</em>. Finally, the previous natural enemies could have a promising role when planning Integrated Pest Management (I.P.M.) strategies with other safe methods to protect the surrounding environment from pollution.

A field experiment was carried out in El-Kossia district, Assiut Governorate during early summer plantations of 2013 and 2014 in order to study numerical density of three phytophagous mites (i. e. <em>Tetranychus urticae</em> Koch, <em>Tetranychus cucurbitacearum</em> (Sayed) (Acari: Tetranychidae) and <em>Aculops lycopersici</em> (Massee) (Acari: Eriophiidae)) inhabiting three vegetable crops squash, <em>Cucurbita pepo</em> L.; common bean, <em>Phaseolus vulgaris</em> L. and tomato, <em>Lycoperiscon esculentum</em> Miller, in addition to study the survey of the soil mites under the previous three vegetable plantations.
Results indicate that <em>T. urticae</em> Koch infested the three vegetable crops; <em>T. cucurbitacearum</em> (Sayed) infested squash and the common bean. While <em>A. lycopersici</em> was found only on tomato plantations. The survey study revealed the presence of 33 mite species belonging to 20 families. The Mesostigmata mites ranked the first as they included the highest numbers of species (13 species) followed by the Cryptostigmata mites (11 species); the Prostigmata (6 species) and the Astigmata (3 species).
The results obtained in the present study should be taken into account in planning programs when conducting the integrated pest management in the three previous vegetable fields. On the other side, it must be performed exclusively survey for all mite species on either the green leaves or soil beneath of those vegetable plants at Assiut area.

The effect of seed treatments of common bean plants (cv. Nebraska) with Bion, Salicylic Acid (SA) and <em>Paenibacillus polymyxa</em> on infection with <em>Rhizoctonia solani</em> under greenhouse and field conditions was investigated. In greenhouse experiment, all treatments decreased percentages of pre and post-emergence damping- off compared with control grown in infested soil by <em>R. solani</em>. The highest percentage of survival plants was achieved from treatment with Bion 5mM (80%) followed by each of Bion 3mM and SA 5mM (76.7%) compared with control (40.1%). Meantime, significant increases in the values of shoot length, shoot dry weight and root dry weight over the control treatment were achieved<em>.</em>
Under field experiments during summer 2009 and 2010 growing seasons, all the tested treatments significantly increased the percentage of survived plants compared with the control. There were no significant differences between the treatments with Bion 3mM and fungicide (Rhizolex-T 3g/Kg seeds) 89.4% and 89.3 %, respectively compared with untreated control 67.9% calculated as means of the two seasons. Also, the treatments with salicylic acid and <em>P. polymyxa </em>were less effective regarding survival plants in 2009 and 2010 growing seasons. Moreover, all treatments significantly increased all the studied vegetative characteristics, i.e. stem length, number of leaves/plant as well as fresh and dry weight of leaves/plant compared with untreated control. Meanwhile, higher increase pe in seed yield (kg/feddan) was estimated with bion and fungicide treatments (86% and 87.7%, respectively) followed by salicylic acid and <em>P. polymyxa</em> (66.8% and 55.4 %, respectively) increasing over the untreated control calculated as means of the two seasons.
Laboratory studies indicated that, all treatments were effective in eliciting the activities of peroxidase and polyphenol oxidase. Peroxidase activity was higher with Bion followed by SA treatments; they showed 77.7% and 41.2 % increase over the untreated control, respectively. Meantime, elevation of the polyphenol oxidase activity was showed with Bion followed by SA treatments as 97.7% and 58.0% increasing over the untreated control, respectively. However, Bion treatment resulted in the highest increase in total phenols contents over the untreated control (94.3%) followed by SA and <em>P. polymyxa</em> treatments (57.9% and 52.6%) over the untreated control, respectively.
