Population of spiders were estimated monthly during the period of study to know their distribution allover the year. Data showed that twenty-two families, belonging to sub-order labidognatha distributed in Al-AzharUniversity and Banymore localities, Assuit Governorate during two successive years. Data indicated that the members of families Gnaphosidae, Lycosidae, Miturgidae, Philodromidae, Salticidae, Theridiidae and Thomisidae were found during the two years (2007/2008 and 2008/2009)in the two localities with highly total individuals, population density and frequency of occurrence. While, the members of families Dictynidae, Hersiliidae, Pholicidae and Scytodidae were found in moderate numbers, population density and frequency of occurrence. Whereas, the other families of spiders were recorded in lowest numbers, population densities and frequencies of occurrence.https://jppp.journals.ekb.eg/article_83721_fa4e05a5e192f8596291ef44d53f4efc.pdfMansoura University, Faculty of AgricultureJournal of Plant Protection and Pathology2090-36773220120201EVALUATION OF MICROBIAL CONTROL OF THE COTTON LEAFWORM, Spodoptera littoralis (BOISD.)

bladder cancer patients in addition to high-risk people to these types of cancers such as hepatitis C virus and chronic bilharzias as well as apparently healthy people as a control. The collected blood samples passed through separation of serum, extraction, evaporation, concentration and determination using gas liquid chromatography equipped with electron capture detector. The monitoring of 14 organochlorine pesticides, characterized by their long persistence in human tissues which are HCB, alpha-HCH, beta-HCH, gamma-HCH, delta-HCH, Aldrin, Dieldrin, Heptachlor and Heptachlor Epoxide, Endrin, o,p’-DDT, p,p’-DDT, p,p’-DDE and p,p’-DDD and polychlorinated biphenyls congeners (PCB’s) no. 28, 52, 101, 118, 138, 153, and 180. The results showed that only DDT (mainly p,p`-DDE ),HCH (mainly beta-HCH) and HCB were detected with high frequency 97% and 77.8 and 2% respectively, while polychlorinated biphenyls residues and other chlorinated pesticides were not detected in any analyzed blood samples. The findings indicate that the higher significant levels of total HCH (mainly beta-HCH) and total DDT (mainly p,p’-DDE) in bilharzias and hepatitis C virus with respect to those found in apparently healthy subjects as a control which indicate the possible role of chlorinated pesticides in neoplastic transformation of bladder and liver as well.https://jppp.journals.ekb.eg/article_83725_15ae653188bf2c7b2a2a88f10b09d218.pdfMansoura University, Faculty of AgricultureJournal of Plant Protection and Pathology2090-36773220120201ORAL TOXICITY AND REPELLENT EFFECT OF SOME INSECTICIDES AGAINST HONEYBEE WORKERS1291378372610.21608/jppp.2012.83726ENW.

Results showed that all the tested compounds comparing to Dursban are safe to forging honeybee workers when fed orally with serial of concentrations started with field rate, 1/2 field rate till 1/4 field rate after 24, 48 and 72 hours of application. Dursban recorded 100% mortality after 48 and 72 hours with field rate while rest of tested compounds did not exceed 17.5% mortality with Jojoba oil after 72 hours at field rate. In case of repellent effect, Dursban recorded the highest repellent impact in initial, after one and two days for both studied seasons, Jojoba extract recorded highest repellent effects against honeybee workers in initial time in both seasons recorded 47.36 and 39.70%, respectively. https://jppp.journals.ekb.eg/article_83726_b783bae48fb434a3b0a466f098c010b7.pdfMansoura University, Faculty of AgricultureJournal of Plant Protection and Pathology2090-36773220120201RISK EXPOSURE ASSESSMENT OF SOME PESTICIDE RESIDUES DETECTED IN FRUIT AND VEGETABLES COLLECTED FROM DIFFERENT EGYPTIAN LOCAL MARKETS DURING 20081391608372710.21608/jppp.2012.83727ENMona A.KhorshedCentral Laboratory of Residue analysis of Pesticides and Heavy Metals in Food, Agricultural Research Centre, Ministry of Agric., Dokki, Egypt.Journal Article20200419A total of 530 samples of different types of the fruits and vegetables collected from nine Egyptian local markets located in nine governorates throughout 2008. All samples were examined for residues of 80 pesticides. Overall, results showed that 84.5% of the samples had no detectable pesticide residues, however, 15.5% contained detectable residues, of which 4.5% contained residues that exceeded maximum residue limits (MRLs). Apricot, banana, green celery, lettuce, samples were free from pesticide residues. The fruits samples recorded the highest contamination percentage without exceeding of the levels of MRL’ (i.e. 20.8%), followed by vegetables (i.e.8.7%), and the leafy vegetables had the lowest percentage (i.e. 6.3%). Also, data showed that the leafy vegetables recorded the highest violation % (i.e. 7.2%), followed by fruits (i.e. 4.2%), and vegetables (i.e. 3.7%). The violated samples were guava, strawberry, orange, carrot, cauliflower, cucumber, eggplant, G. beans, G. peas, pepper, potatoes, tomatoes, watercress, G. coriander, and G. parsley. The violated compounds were cypermethrin, chlorpyrifos, diazinon, fenhexamide, profenofos, fenhaxamid , ethion, and chlorfenapyr .The highest frequently detected pesticide was profenofos, followed by lambada-cyhalothrin, fenhexamid , cypermethrin , ethion, chlorpyrifos , fenpropathrin , diazinon and imiazalil , carbendazin, dimethoate, and procymidone. However, the lowest frequently detected pesticides, which detected only one time, were boscalid, chlorfenapyr, flusilazole, iprodione, metalaxyl, pirimiphos, and pyraclostrobin. The results showed that 2.08% of all samples analyzed, contained residues of 9 pesticides, 1.13% contained residues of 8 pesticides, 0.94% contained residues of 6 pesticides, 2.26% contained residues of 5 pesticides, 0.38% contained residues of 4 pesticides, 3.21% contained residues of 3 pesticides, 3.4% contained residues of 2 pesticides, and 2.08% contained residues of 1 pesticide. The dietary exposures of the most frequently detected pesticides were theoretically calculated to evaluate the risk for Egyptian consumer. As shown by the results, the intake of pesticide residues does not exceed the ADI in any case. It is found to be below 10% of the ADI for all pesticides. The estimated exposure ranges from 0.00018% of the ADI for the malathion on each of molokia and spinach to 4.9% of the ADI for the ethion on tomato. https://jppp.journals.ekb.eg/article_83727_2038a556092f08dba5a2beb2026ef64b.pdfMansoura University, Faculty of AgricultureJournal of Plant Protection and Pathology2090-36773220120201ROLE OF CERTAIN INORGANIC FERTILIZERS ON CONTROLLING Meloidogyne incognita INFECTING TOMATO PLANTS UNDER GREENHOUSE CONDITIONS1611788373110.21608/jppp.2012.83731ENA.

Similar trend was noticed regarding reduction of nematode criteria such as population density (90.8, 90.7 and 90.2%) respectively. Likewise, nematode multiplication was also affected by the tested nutrient elements performing the above trend, where CaCl<sub>2</sub> at 200 mg/l and ZnSO<sub>4</sub> at 50 mg/l/plant represented of minimum and maximum values that averaged 0.13 and 0.16 vs 1.39 for nematode alone respectively.
