A.HalawaPlant Protection Research Institute, Agricultural Research Center, Dokki, Giza.M. K.El-AnsaryPlant protection Dept. Fac. Agric. Al-Azhar UniversityJournal Article20200503This study was carried out during the period from December 2008 to December 2009 at Alexandria Governorate. The product samples were obtained from General Soils and Agriculture Credit Bank. Eight species, belonging to two orders; <em>Cleoptera and Lepidoptera</em> and only five families were recorded on wheat, wheat flour, yellow corn and barley. The survey revealed about seven species of <em>Clepotera </em>and one species of <em>Lepidoptera</em>.
This situation of these insects as pests in Egypt or other parts of the world, the effect of sample site inside or outside of G.S. and A.C.B and monthly distribution of insect infestation are considered and discussed for each insect in each product.
The recorded data showed that the lowest infestation rate occurred at barley and yellow corn. But, the highest infestation rates were at wheat followed by wheat flour.https://jppp.journals.ekb.eg/article_86710_7609737911da20be6462f466cb226156.pdfMansoura University, Faculty of AgricultureJournal of Plant Protection and Pathology2090-36771420100401THE RELATIONSHIP BETWEEN THE INCIDENCE OF BACTERIAL SPOT DISEASE OF PEPPER AND SOME ENVIRONMENTAL FACTORS1571648671110.21608/jppp.2010.86711ENS.

The present work was planned to record the disease incidence under protected agriculture and open field conditions in different localities of Nile Delta. Also to study the relationship between environmental factors (average daily temperature and relative humidity) and disease severity. The results showed that the open fields were free from the disease during the growing seasons of 2007-2009. Under the protected agriculture conditions, the disease was shown in all surveyed localities. The highest disease severity was recorded in El-Khatatba, El-Fayoum and El-Salhia regions, while it was moderately shown at El-Bosaily; Gazera-El-Dhab, Kha and El-Giza region. However, the disease severity on pepper increased with increasing the average of daily temperature and relative humidity. The disease was sever in the growing seasons 2007-2008 and less in 2008-2009 seasons and this phenomena probably due to the change in the climate between the two different seasons.https://jppp.journals.ekb.eg/article_86711_82da94104e7d5981bd6e7cc16d3e22c3.pdfMansoura University, Faculty of AgricultureJournal of Plant Protection and Pathology2090-36771420100401APPLICATOR EXPOSURE AND DRIFT PROBLEMS OF CYANOPHOS INSECTICIDE APPLIED ON COTTON FIELD USING TWO APPLICATION METHODS1651778671210.21608/jppp.2010.86712ENSh.

Agric., Al-Azhar Univ., AssiutJournal Article20200503Two sprays of cyanophos were applied on cotton plants adjacent to maize field by two methods of application, i.e. micron ULVA and a motorized knapsack mistblower. Operator exposure during application, drift residues on maize plants and the toxicity of these residues on fish and honeybees were estimated. Fish and bees were located on the ground of maize field at different distances from the edge of the cotton field. Dermal exposure was determined by measuring cyanophos on pieces of clothing fitted to applicator overall within the time specified for application. Results show that the higher level of deposition of the insecticide on the total area of all cloth patches fitted on different body regions was observed for the micron ULVA (total deposition for the two sprays was 11.8 mg within exposure time of 9.5 min versus 3.82 mg for the mistblower at the same exposure time). Deposition on different body organs could be arranged descendingly as follows: hands> legs> knees> chest> elbows or shoulders. Deposition was more in 1<sup>st</sup> spray than in 2<sup>nd</sup> one, mainly due to the difference of wind speed. At the 1<sup>st</sup> spray, distances traveled by cyanophos residues were 24 and 33 m when using the mistblower and micron ULVA, respectively. At these distances, the corresponding values of mean deposits were 16.5, 11.6 µg/kg of maize leaves, respectively. At 2<sup>nd</sup> spray (lower wind velocity) the distances were 18 and 24 m corresponding to 19.3 and 10.6 µg/kg maize leaves, respectively. Drift of cyanophos released by each of the tested equipment caused 100% mortality of fish and honeybees placed at the distances 3 and 6 m, respectively. Zero mortality for both organisms were observed at distances 18 and 30 m for the mistblower and micron ULVA, respectively. It is obvious that levels of dermal exposure or drift to non-target sites were higher for micron ULVA than for the mistblower. These levels were markedly affected by wind speed.

The resistance ratio (RR) reached 56.73 fold-resistances. The larval development of resistant, susceptible and their F<sub>1</sub> generation were significantly varied while reared on normal artificial diet. The growth rate of resistant strain was slower compared with susceptible and F<sub>1</sub> strains. The present study shows asynchronism effect for Cry1Ac resistant strain in relation with susceptible and F1 strains. The overlapping distribution between the adult peak of resistant and the adult peak of susceptible were investigated and found to be apart from each other. Subsequently, the probability of random mating among resistant individuals would be more likely to be happened that helps insect resistance development within the population. Thus, the current study would recommend reviewing the implementation of refuge strategy (non Bt cultivated area) while adopting Bt modified crops.https://jppp.journals.ekb.eg/article_86713_24693bb0576bf1653ed6d3a48a178721.pdfMansoura University, Faculty of AgricultureJournal of Plant Protection and Pathology2090-36771420100401FOOD PREFERENCE AND FOOD CONSUMPTION OF SOME LAND SNAILS UNDER LABORATORY CONDITIONS.1891938671410.21608/jppp.2010.86714ENT.
