The Seasonal abundance and population trends of red palm weevil, <em>Rhynchophorus ferrugineus</em> Oliver (male and females ) population was estimated during two successive years (2008 and 2009) by using aggregation pheromone traps in date palm orchards located at Arement, Giza Governorate .
The results obtained during the two years of study have dearly showed that adult stage of red palm weevil,<em> Rhynchophorus ferrugineus</em> has two peaks of swarming activity on date palm trees throughout the year. In both years, the first peak occurred during March ,while the second one occurred during October.
Number of attracted female was considerable high than attracted males. Correlation analysis indicated there was insignificantly positive correlation between trap catches and infestation date palm .

The interspecific interactions between different larval instars of two aphidophagous predator species,<em><em>M. corollae</em></em>and<em> E. nigromaculatus</em> were examined under laboratory conditions. Intraguild predation (IGP) between predators was studied in various larval densities of the predator and in the presence or absence of extraguild prey aphids after 24 hours. There was a highly significant difference of IGP at the different densities in the presence or absence of aphids between the 1<sup>st</sup> instar larvae of <em><em>M. corollae </em></em>by the <em>2<sup>nd</sup> instar larvae of </em><em>E. nigromaculatus</em> and when the 1<sup>st</sup> instar larvae of <em><em>M. corollae </em></em>was confined with the 3<sup>rd</sup> i<em>nstar larvae of </em><em>E. nigromaculatus</em>. The highest IGP percentage by the 4<sup>th</sup> instar larvae of <em>E. nigromaculatus </em>against the 1<sup>st</sup> instar larvae of <em><em>M. corollae</em></em> was observed at the fifth level of density in the presence or absence of aphids. IGP on the 2<sup>nd</sup> instar larvae of <em><em>M. corollae </em></em>by the <em>2<sup>nd</sup> instar larvae of </em><em>E. nigromaculatus</em> differed significantly at the various densities in the absence of aphids, but no significant difference was found on IGP between them in the presence of aphids. The predation by the<em>3<sup>rd</sup> instar</em><em>larvae of</em><em>E. nigromaculatus</em> against the 2<sup>nd</sup> instar larvae of <em><em>M. corollae</em></em> rose at both fourth and fifth levels of density in the presence of aphids. Meanwhile, in the absence of aphids, the highest level of IGP was obtained at the fourth level of density. IGP rate by the 4<sup>th</sup> instar larvae of <em>E. nigromaculatus</em> against the 2<sup>nd</sup> instar larvae of <em><em>M. corollae</em></em> differed significantly at the different densities in the presence or absence of aphids.
The influences of larval density and prey presence or absence on the incidence of intraguild predation among the two predator species were considered and the outcome of predatory interference between them is discussed.

Intraguild predation (IGP) on egg and the role of surface chemicals in two aphidophagous coccinellids species, <em>C. undecimpunctata</em> and <em>C. visina isis </em>were examined. The first instar larvae of both species prefer to eat washed heterospecific eggs than unwashed eggs. Surface chemicals appear to play a major role for the preference of washed eggs, as the ladybeetle behavior was reversed when these chemicals were remained. The surface chemicals present on the eggs appears to reduce intraguild predation. The green lacewing, <em>Chrysoperla carnea</em> (Stephens)in its first instarconsumed <em>C. undecimpunctata</em> and <em>C. visina isis</em> eggs without showing any preference for either washed or unwashed treatments, although we observed that the washed eggs were eaten more than those unwashed. The average number of coccinellid eggs consumed by the first instar larvae of other predator species was determined and the results are discussed.

Four chemical substances <em>i.e</em>. salicylic acid, oxalic acid, disodium phosphate and ethephon were tested, as seed soaking treatments, to study their effect on reducing the severity of root-rot disease of chickpea plants caused by <em>Rhizocotnia solani</em>. In vitro studies showed that the tested chemicals significantly reduced the linear growth of the fungus .
The greenhouse experiments showed that salicylic acid, disodium phosphate and ethephon were effective chemicals in reducing the root-rot disease and significantly increases seedling survival,.A significant increase in the activity of chitinase enzyme was also recorded in plants grown from the treated seeds. Salicylic acid increases the activity of oxidative reductive enzymes (peroxidase and chitinase enzymes ) in the plants tissues . In the field experiments salicylic acid proved to be the most effective chemical in reducing the root-rot disease as will as increases the yield components.

Three different analytical methods were used in this investigation to choose the suitable method with high recovery to validate an analytical method for pesticide residues in honey samples.
The systems of GC/NPD and GC/ECD were used to measure recoveries from spiked samples. The honeybee samples free from residues were spiked at one level and the recoveries of pesticides were studied. Spiked level was settled according to the detectors sensitivity to test pesticides in the range of 0.05 – 1.0 µg/g. The three tested analytical methods gave relatively high recoveries for the tested pesticides (84.1-99.5%) with standard divisions varying from ± 8 to 10.7% for different pesticides.
The percent mean recoveries of tested pesticides in the 1<sup>st</sup>, 2<sup>nd</sup> and 3<sup>rd</sup> analytical method were 92.3, 84.1 and 99.5%, with standard deviations ±10.7, 9.8 and 8.0%, respectively. In general, the recoveries obtained with the third analytical method were always higher than those obtained with the first and second analytical methods, with low standard deviations.
All the collected honey samples during two years were free from any pesticides contamination except one sample was obtained at year 2005 from Ehnasia district of Bani Suwayf Governorate. This sample was contaminated with the insecticide chlorpyrifos -ethyl at concentration 0.02 µg/g (below the quantification limit 0.05 µg/g). The presence of residue of such compound in the samples analyzed may be attributed to intensive use of chlorpyrifos -ethyl in cotton fields in controlling the cotton leaf worms and cotton boll worms.

Two plants; <em>Hyoscyamus muticus</em> and <em>Ambrosia maritime</em> were chosen in order to investigate the toxticty of their leave, stem, flower or root extracts (using ethanol, acetone, chloroform and hexane) to nymph and adults of <em>Aphis craccivora</em> and its predator <em>Chrysoperla carnea</em>. The plant extracts were treated using direct spraying on infested bean seedlings. The results showed that for the two plant species, high concentration of leave extract in ethanol and acetone gave a high mortality rate after 24 and 48 h. For the flower extracts, high concentration in ethanol and chloroform resulted as well in high mortality rate of the pest after 24 and 48 h. As far as the root extracts are concerned only <em>H.muticus</em> at a high concentration in ethanol gave high mortality rate after 24 and 48 h. For the stem extracts, only <em>H.muticus,</em> at a high concentration in hexane resulted in a high mortality rate after 24 and 48 h. Moreover these high plant extract concentration were not detrimental <em>Ch. carnea</em> and thus can be considered as safe adjuvant in the prospect of integrated pest control.

Field experiments were conducted at the Farm Horticulture Services Unit, Gemmiza, Agric. Res. Station (Middle Delta), Santa, Gharbia Governorate, during two successive seasons of 2008 and 2009 to study the occurrence of the spiny boll worm,(SBW), <em>Earias insulana</em> (Boisd.) in some its host plants. The hosts were Cotton, <em>Gossypium barbadense</em> L. (Varity Giza 86 ); Maize<em>, Zea maize</em> L. (Pioneer 3062); Khtmia weed, <em>Hibiscus trionum</em> L.; Okra, <em>Hibiscus esculentus</em> L.; Roselle, <em>Hibiscus sabdarifa</em> L. Occurrence period of the SBW larval infestation in the cotton terminal shoots and fruit structures extended from mid May to the end of September and occurred in three peaks. Inthe silk and ears of maize the SBW larval infestation period occurred from late July to late September at one peak. Inbladder capsules, the larval infestation period started from the first week of June and extended to the third week of September at 2-3 peaks<strong>. </strong>In okra, it occurredfrom the first week of August and extended to last week of Octoberat 2 peaks<strong>. </strong>In Roselle, it was recorded from mid September to mid November at 2 peaks. The bladder weed acted as a source of SBW infestation followed by cotton, Maize then okra, and was the most important host in summer for the occurrence of the SBW population. While some other hosts as Roselle acted as source of SBW infestation followed by wintry hosts, which were grown, in Egypt, had the sustain of SBW infestation during a critical period of its seasonal history that extended from December to April.

Six different essential oils and their joint toxic effect with Vitavax-thiram were tested to control Sclerotium root-rot disease of sugar beet (<em>Beta vulgaris</em> L.) caused by <em>Sclerotium rolfsii</em> Sacc. <em>in vitro </em>all the tested oils exhibited effect on fungal growth of <em>S. rolfsii</em>. <em>Cuminum cyminum</em> oil was the most effective in inhibiting linear growth of <em>S. rolfsii</em>. The joint toxic effect between Vitavax-thiram and oils of <em>Eucalyptus globulus</em> and <em>C. cyminum</em> showed the highest effect in reducing the growth of <em>S. rolfsii</em>. Under greenhouse conditions, data indicted that oils have significant effect in improving the number of survived seedlings and reduced root-rot. Seed treatment with <em>C. cyminum</em> oil was more effective in controlling damping-off and root-rot diseases of sugar beet and increasing sucrose percentage, total soluble solids percentage (T.S.S%) and purity % of sugar beet plants sown in soil infested with <em>S. rolfsii</em>. Vitavax-thiram mixed with <em>E. globulus</em> or <em>C. cyminum</em> oils as a seed treatment were the most effective in controlling root-rot disease and increasing percentages of T.S.S., sucrose and purity. <em>C. cyminum</em> showed highest values in increasing activities of peroxidase and esterase enzymes. In the field, coating or soaking of sugar beet seeds with <em>C. cyminum, Nigella sativa, Allium sativum</em> and <em>Matricaria chamomilla</em> oils completely controlled root-rot infection, but <em>C. cyminum</em> gave the highest yield/plot in comparison with other oils. Vitavax-thiram combined with <em>E. glubulus</em> and <em>M. chamomilla</em> as a seed coating were completely effective in reducing sugar beet root rot, but <em>E. glubulus</em> and <em>A. sativum</em> as a seed soaking were the best treatments in controlling root rot disease. Analysis by gas chromatography-mass spectrometry (GC-MS) led to identification of 62 organic compounds from <em>C. cyminum</em> oil including hydrocarbons, alcohols, aldehyds and … etc.

Five natural ethanolic plant extracts of <em>Rhazya stricta</em>, <em>Caralluma tuberculata</em>, <em>Capparis spinosa</em>, <em>Marrubium vulgare</em> and <em>Argemone ochroleuca</em> were tested in the laboratory for their insecticidal and repellent effectiveness against saw-toothed grain beetle, <em>Oryzaephilus surinamensis</em> (L.). Four concentrations of each plant extract, 200, 400,600 and 800 ppm were tested. Larvae and adult beetles were exposed to plant extracts for 6 days. Mortality percentage was recorded after 2, 4 and 6 days from exposure. The repellent action of the previous plant extracts was also, studied. All of these extract showed remarkable toxicities. Results showed that complete mortality of <em>O. surinamensis</em> was achieved by <em>C. tuberculata</em> and <em>R. stricta</em> at the concentration of 800ppm for both larvae and adult beetles. The rest of plant extracts increased mortality with increasing of concentrations. Of five plant extracts, the effect of <em>C. tuberculata</em> and <em>R. stricta</em> were relatively more pronounced with LC<sub>50</sub> values of 203, 970 and 244, 245 ppm, respectively, two days from treatment. Corresponding LC<sub>50</sub> values after six days exposure for larva, values were 114, 615 and 117, 775. As for adult, the LC<sub>50</sub>s values after 2 days were 210.062 and 238.563. After 6days, LC<sub>50</sub>s were 123.295 and 127.182 respectively.
Moreover, <em>R. stricta</em> and <em>C. tuberculata</em> exhibited high repellency 100% and 90.08% at concentration of 800 ppm against <em>O. surinamensis</em> adults.
The application of these extracts may be promising in protecting of stored date and grains against the attack of <em>O. surinamensis</em> specially extracts of <em>C. tuberculata </em>and<em> R. stricta. </em><em> </em>
