The study aimed to investigate the relationship between colony survival and some preventive procedures. The experiments were conducted in Sulemani governorate during August, September and October 2020. Seventy-two colonies were tested in four localities ( Qaradax , Sulaimani center, Mergapan, and Sartake bamo ); (18 colonies for each location). The tested colonies were treated with; probiotics, formic acid, eucalyptus, Tetracycline and Terramycin. Larger brood area was found in all treated colonies compared to untreated ones. Colonies provided with probiotics showed significantly more brood than untreated colonies in the four locations. Maximum brood area was 203.667 (inch)<sup>2 </sup>in Sartake bamo followed by 199.667 (inch)<sup>2 </sup>in Mergapan; then 179.000 (inch)<sup>2 </sup>in Sulaimani center. While the brood area was not more than 15.667 (inch)<sup>2</sup> in all untreated colonies in the four tested apiaries. Colonies provided with probiotics showed significantly more density of adult workers than untreated colonies in the four locations. Maximum area covered with adult workers (density) was 6.667 Lf. (Langstroth frame)in Sartake bamo followed by 6.333 Lf. inMergapan; then 6.000 Lf. <sup> </sup>in those treated with Formic acid in Sartake bamo. While the density of adult workers was not more than 1.000 Lf. in all untreated colonies in the four tested apiaries. Using probiotics and organic acid treatments were the best preventive measures.

The present work was conducted to study the effectiveness of powdered seeds of six plant species namely: Brassica rapa, Eruca sativa, Juniperus communis, Lepidium sativum, Raphanus sativus, Sinapis alba on controlling Meloidogyne incognita infecting pepper plants cv. Top Star under greenhouse conditions. The application of S. alba seed powder overcome other treatments and accomplished the highest reduction percentages of nematode stages with the maximum values of 93.09, 93.94, and 95.75% for final nematode population, galls, and egg masses numbers, respectively at a rate of 6g/plant, while the least values were achieved by E. sativa seed powder with values of 67.88, 77.38 and 81.71 % for previous criteria, respectively at a rate of 2g/plant. There was a significant improvement in the plant characters (length, fresh weight & dry weight plant and leaf numbers). Among all treatments, the best plant growth character (plant length:143.1%, fresh weight:118.4%, dry weight plant:100.0%, and leaf numbers:99.5%) were observed with B.<strong> </strong>rapa grind seeds, followed by J. communis at a rate of 6g/plant. Increasing the used powdered seed rate from 4 to 6g/plant for S. alba and L.<strong> </strong>sativum cause a decrease in the plant growth parameters. Overall, all tested applications increased the percentages of chemical constituents i.e., nitrogen, phosphorus, and potassium concentrations, and phenol contents as well as decrease total chlorophyll percentages to a certain extent. The present study indicated the potential of screened plant seed powders to control M. incognita under greenhouse conditions and can be used as soil amendments after further investigations.

The present studies were conducted at the experimental farms in Agricultural Research Stations of Kafr El-Sheikh and Nubaria regions during two seasons (2019/2020 and 2020/2021) to survey the insect pests and predators that inhibiting sugar beet crop, and to study the seasonal abundance of main insect pests in such crop, and to evaluate the impact of some climatic factors in both regions on the seasonal abundance of some serious insects. Survey studies revealed that sugar beet plants attacked by 45 insect species: 15 of them were accidently visitors. In addition, ten predator species were recorded during the period extended from October until April in both regions during the two seasons.<em> Spodoptera littoralis</em> larvae gave the highest monthly average in December, while <em>Pegomyia mixta</em> larvae recorded the highest monthly average numbers in February and March in Kafr El-Sheikh and Nubaria regions in both seasons. On the other hand, the highest monthly average numbers of <em>Cassida vittata</em> adults were recorded in April in Kafr El-Sheikh region but in February-March in Nubaria region, during both seasons. <em>Scrobipalpa ocellatella </em>appeared with the highest monthly average only in April of both seasons in Kafr El-Sheikh. Whereas, itdoesn’t exist in Nubaria region. Results revealed that effects of the three weather factors (temperature, relative humidity and wind speed) were non-significant during the two seasons in both regions. I could be concluded that sugar beet plants that cultivated Nubaria region received less numbers of insect species than that cultivated in Kafr El-Sheikh region, and given that the sugar beet crop is considered a reclamation crop for new lands, so it must be reassurance in its cultivation due to the lack of insect infestation as well.

The present study was conducted to estimate the distribution of apterous and alates cotton aphids within and between plants. Also, population dynamic of cotton aphid and its predators, and the effects of foliar spray with elicitors viz, salicylic acids (SA), jasmonic acids (JA) and β-aminobutyric acid (BABA) on the population density of <em>A. gossypii</em> were estimated. The experiments were carried out in an eggplant field at Nobaria district, El-Beheira Governorate, Egypt. The results of spatial distribution of apterous <em>A. gossypii</em> by using the diffusion coefficient (S<sup>2</sup>/ m) was >1, by using David-Moore index (I<sub>DM</sub>) was positive value for negative binomial, by using patch index (m*/m) was >1 and with using Cassie index (C<sub>a</sub>)was>0 and positive values. All these indices are indicative of aggregation (the individuals tend to occur in clumps) distribution model for the apterous <em>A. gossypii</em> in all the sampling dates throughout the two successive seasons 2019 and 2020. On contrary, all of these indices refer to a uniform spatial distribution for the alates <em>A. gossypii</em>., there were proportionally greater numbers of the alates individuals on the middle part of eggplants. The results also showed that the seasonal mean population of cotton aphids was higher during 1<sup>st</sup> season than during the 2<sup>nd</sup> season The apterous aphid populations were significantly higher within the upper level than other levels of the plant. The foliar spray of JA, SA and BABA resulted in decreasing the cotton aphid population density in eggplant crop. SA proved to be less efficacious than JA and BABA.

The effects of future climate changes on the prevalence of <em>Palarus </em><em>latifrons</em> Kohl. and <em>Philanthus</em><em> triangulum</em> Fab that attacking honey bee colonies in Africa have not been studied before. Ecological modeling using Maxent and geographical information system (GIS) was used to achieve the study objective. The highest contribution in the model was to the annual mean temperature followed by mean temperature of the coldest quarter. The model performance was high and perfect in light of the used evaluation parameters. Some areas in southern and northern parts of Africa were suitable for the prevalence of<em> P. </em><em>latifrons</em> Kohl. and <em>P.</em><em> triangulum</em> Fab under current conditions.The study maps for future conditions during 2050 and 2070 highlighted the negative effects of climate change on the prevalence of these pests in specific parts in Africa. The consequences of such prevalence/limitation of <em>P. latifrons and P. triangulum </em>on beekeeping in Africa were discussed.

This project target aim to investigate the hydrolysis of fungicide chlorothalonil at different pH solutions at (pH4, pH7, and pH9), as well as its stability under exposure to different temperature degrees and direct exposure to sunlight, and to estimate the photoproducts degradation of chlorothalonil using GC/MS. The data showed that chlorothalonil dissipation from different pH solutions increased more rapidly with increasing both pH value and temperature when compared to acidic and neutral solutions, and that tested pesticides were hydrolyzed more rapidly in alkaline media (PH9) than the other tested pH values at all tested temperatures. The percentage of pesticides that decompose steadily increases and is positively connected with exposure times, according to the data. The results also demonstrated that after 336 hours of exposure to direct sunlight, no detectable level of the pesticides tested was found. The compound (4-hydroxy-2,5,6-trichloroisophthalonitrile) was identified as a major metabolites in environmental samples after photo-degradation products were investigated using GC/MS following exposure to direct sunlight.

Mediterranean fruit fly, <em>Ceratitis capitata</em> (Wied.) is a serious horticultural insect pest in Egypt, Mediterranean basin and many countries of the world. Licorice, <em>Glycyrrhiza glabra</em> L. is a plant growing in Egypt and many other countries and famous for saponins groups that have insecticidal effect against broad spectrum of insect pests. Licorice roots aqueous extract (LRAE) 1150, 700 and 300 ppm/l were tested for the insecticidal effects against <em>C. capitata</em> full-grown larvae and different pupal ages (one, three, five and seven day old pupae) by dipping for 30 and 60 seconds. Dipping treatment in LRAE for 60 seconds decreased the tested stages of <em>C. capitata</em> more than 30 seconds treatment. Full-grown larvae population was suppressed by 99.33% after larval dipping in LRAE 1150 ppm for 60 seconds. Based on toxicity values, three days old pupae were the most responded pupal age to LRAE dipping treatments for 60 seconds with LC<sub>50 </sub>1.5×10<sup>1</sup> and LC<sub>90</sub> 1.80×10<sup>2</sup> ppm/l. Histological studies cleared that larval tissues were affected externally and internally after treatment with LRAE. Emerged flies were not able to either feed or move normally. The histological studies of flies showed that mouthparts, the maxillary palps, foregut neuropil areas, and tracheal tubes were severely affected. The treated flies female ovaries and male testis showed normal view of tissues. Phytochemical screening of powdered licorice roots methanolic extract proved presence of phenols, flavonoids, terpenoids, saponins, tannins and steroids compounds. Saponins compounds were the major constituent of licorice roots methanolic extract.
