The residual behavior of abamectin (Vertimec 1.8 %EC), diniconazole (Sumi-eight 5% EC) methomyl (Lannate 90 %SP) and phenthoate (<strong>Cidial-L 50 % EC)</strong> in sweet bell pepper fruits under the greenhouse condition of Egypt was studied. The tested pesticides were sprayed at recommended dose of 50 ml in 100 liter water for abamectin and diniconazole per 200 m<sup>2</sup>, 100 ml and50 ml in 100 liter water per 660 m<sup>2</sup>for methomyl and phenthoate respectively on pepper fruits (foliar application). The treated sweet bell pepper fruits were randomly sampled in triplicates after one hour (initial), five hour, 1, 3, 5, 7, 10, 15 and 21 days period after pesticides application including control samples one hour before application. For abamectin 1 h, 3 hour, 5 hour, then 1, 3, 6, 9, 13 and 20 days. Samples were extracted using QuEChERS method and analyzed using LC/MS/MS. The four pesticides residues dissipated during 20 days post treatment, though at a slower rate and the residues amounts in fruits were much higher in case of methomyl and phenthoate. The pre-harvest interval (PHI) was determined to be 3, 10, 21 and 21 days for pepper fruits treated with abamectin, diniconazole, methomyl and phenthoate under greenhouse conditions, respectively.

Ginger rhizomes extract was obtained by using a mixture of organic solvents,( hexane, acetone and ethanol )of equal proportions (1:1:1). Its volatile components were characterized and identified by GC/MS technique giving thirteen compounds. Also, bioactivity of ginger extract against adults and larval stage of <em>T. urticae</em> was evaluated. Ginger extract showed cumulative mortality of adults more than 20.00% at 3rd day post treatment at different concentrations. The cumulative mortality increased to range between 43.33- 66.67% and 46.67-83.33% at 5th and 7th day post treatment, respectively at different concentrations. Also, data showed that ginger extract had a mild effect against adults of <em>T. urticae</em> with LC<sub>50</sub> of 1540 ppm and LC<sub>90</sub> of 10100 ppm.
The larval stage showed more susceptibility than their adults to ginger extract using the same concentrations and exposure time. It showed mortality percentage of 90.00% at 7<sup>th</sup> day of treatment with the higher concentration of 6000 ppm. Also, it showed LC<sub>50</sub> of 928 ppm and LC<sub>90</sub> of 5330 ppm.

The present work was conducted at Laboratory of Seed Technology Research Unit, Mansoura during 2012 year to study the effect of dry heat treatments (50 <sup>o</sup>C , 60 <sup>o</sup>C , 70 <sup>o</sup>C and without heating) for (1 , 2 and 3 days) of some rice cultivars (Sakha 104, Sakha 103 and Giza 178) on seed quality. The obtained results showed that Giza 178 cultivar showed the highest results of seed and seedling vigor characters as compared with other cultivars. Dry heat of all cultivars under study at 60 <sup>o</sup>C for 2 days produced the highest mean of germination percentage, seed and seedling vigor. The lowest values of seed germination, seed vigor and seedling vigor of mentioned cultivars were obtained by heating at 70 <sup>o</sup>C for 3 days . The percentage of seeds infection with fungi decreased at 60 <sup>o</sup>C for two days , there was a decrease in<em> Alternaria padwickii</em>, <em>Alternaria tenuis</em>,<em> Bipolaris oryzae</em> with seed in all studied cultivars and elimination of <em>Fusarium moniliforme, Fusarium semitectum,</em> <em>Helminthosporium sp</em>,<em> Rhizoctonia solani, Sarocladiumoryzae, Stemphylium botryosum </em>with seed of Sakha 103 and Giza 178 cultivars. Stepwise regression analysis revealed that <em>A. padwickii, B. oryzae, F. graminearum, Fusarium semitectum, Helminthosporium sp</em><strong>,</strong><em>R. solani, Sarocladiumoryzae, </em>as significantly contributing variables to variation in germination %. Furthermore, negative and significant correlation coefficient was recorded between germination % and <em>A. padwickii , B. oryzae, F. graminearum .</em> While the negative correlation coefficient between germination % and <em>F. moniliforme, F. semitectum, R. solani, S.oryzae </em>was not significant.
Finally, it could be concluded that heating of rice seed at 60 <sup>o</sup>C for 2 days is a good mean for controlling seed borne disease and enhancement of seed vigor.

The relative attractiveness of some olfactory stimulant materials to the oriental hornet wasp, Vespa orientalis L. was evaluated under laboratory and field conditions. Olfactory stimulant materials included some volatile oils ( cinnamon, bananas, camphor and mint) and other natural materials (yeast, chicken litter, asber fermented grapes and sugar syrup as control). The obtained results revealed that the oriental wasp exhibited different degrees of selectivity in response to the tested olfactory stimulant materials.
<em>V.orientalis </em>adults exposed to different volatile oils showed the highest attractiveness to cinnamon followed by camphor and mint oils with significant differences. The waspsexhibited the lowest preferability to bananas.
The present study indicated that the oriental hornet wasp exhibited significantly positive response to asber fermented grape and chicken litter in comparison with yeast and sugar syrup. So, asber fermented grape and chicken litter successfully attracted the wasp; these materials can be used in monitoring populations of <em>Vespa orientalis. </em>
Traps baited with cinnamon oil proved to be good bio control agent against the oriental wasps as they strongly attractive to them. The oriental wasps,<em> V. orientalis</em> population was considerably decreased in treated apiary in comparison with untreated one. Therefore, cinnamon oil could be used against the oriental wasps in IPM programs.

Laboratory and field studies were conducted to evaluate the effect of three inert dusts, diatomaceous earth, kaolin and katelsous as wheat grain protectants against some stored grain<em> Sitophilus oryzae</em>, <em>Rhizopertha domininca</em> and <em>Tribolium confusum</em>. Inert dusts were mixed with wheat grain in the laboratory at different concentrations.The LC<sub>50</sub><strong><sup>,</sup></strong>s of diatomaceous earth, kaolin and katelsous were 0.234, 0.071 and 0.235% w/w, 6.033, 6.306 and 8.938% w/w and 0.495, 0.496 and 103.875% w/w against <em>S. oryzae</em>, <em>R. dominica</em> and <em>T. confusum</em>, respectively one day after treatment. Diatomaceous earth was more effective than the other tested materials as it achieved complete mortality for the three tested insects after two days of treatment at the rate of 0.5% w/w. Results also showed that kaolin and katelsous act slowly on the tested insects, where the higher rates of 8% w/w for kaolin and 0.4% w/w for katelsous gave complete mortality one week post treatment. For the field study (at farmers<strong><sup>,</sup></strong> storages), the higher concentrations (0.5, 8 and 0.4% w/w) of the three dusts, diatomaceous earth, kaolin and katelsous, respectively were admixed with wheat grain and stored for 6 months at the farms. The results showed that diatomaceous earth gave 100%, 84.4% and 93.3% mortality against the three tested insects, respectively after 6 months of storage at a concentration of 0.5% w/w at 7<sup>th</sup> day of exposure. Kaolin at 8% w/w showed that adult mortality decreased from 100% at zero time of storage after 5 days of exposure to 10.0%, 5.0% and 15.0% at 6 months of storage after the same period of exposure against the three tested insects, respectively. At zero time of storage, katelsous at a rate of 0.4% w/w showed the percent mortalities of 100%, 100% and 95.7% against the three tested insects, respectively at 5 days of exposure. The residual effect after 6 months of storage decreased to 13.0%, 35.0% and 22.0% mortality against the three insects, respectively at 7 days of exposure. In general, the results obtained showed that the diatomaceous earth was the most effective followed by katelsous and kaolin against the three tested insects. Also, the degree of effectiveness decreased with the increasing of storage periods.

The objective of this study was conducted to evaluate the efficacy of four compounds ; achook 0.15% (Azadirachtin) ; cloves-oil (<em>Syzyguim aromaticu</em>) ;Plant extracts damaseia (<em>Ambrosia maritime</em>) and selecron 72.0% EC. (Profenofos) for controlling some squash plants pests; whitefly, <em>Bemisia tabaci</em> (Genn.); <em>Aphis gossypii</em> (Glover.), as well as its effects on squash leaves chlorophyll contents.
Obtained results cleared that cloves oil exhibited the highest reduction percentages of <em>A. gossypii</em> (97.0and 796.9) followed by damaseia extract (94.2&95.1), achook o.15 % (93.0&92.3), while, selecron was the lowest one (89.7and 788.2) after five days of treatment during 2011 and 2012 seasons. While, whitefly reduction percentages after five days of treatment showed that damaseia extract exhibited the highest reduction (100and100) and(98.2and100) of both adult and immature stages ,followed by selecron 72.0% (100& 89.7) and (97.5 &85.0), cloves oil (97.5 &91.2) ,(96.3 &89.4) and achook 0.15% (95.2 &83.2), (90.9 &82.3) during the two seasons respectively.
Squash leaves chlorophyll (a, b ) was the highest with cloves oil treatment, followed by damaseia extract,while it was lowest with both achook and selecron treatments.

The present study was conducted at Kafr El-Sheikh governorate, Sakha district, throughout the peak of the oriental wasp,<em> Vespa orientalis</em> L. during seasons of 2011 and 2012.
The efficacies of a modified Abou El-Enain traps with different height (0.6, o.85, 1.15 and 1.50 m) and new trap desin, wooden shish window traps were evaluated in an apiary and date palm orchard.
The obtained results revealed that shish window trap significantly attracted more numerous hornet wasps than those captured by using all heights of modified Abou El-Enain trap.
The oriental wasp,<em> V.orientalis</em> population was relatively higher in the second season than those captured in the first one. On the other hand, the weekly average number of the hornet fluctuated all over the experimental period in the apiary and date palm orchard.
Relatively higher numbers of the honey bee, Apis mellifera were caught in the modified Abou El-Enian trap, especially at 0.6 m. On the contrary, no catches of honey bee were recorded using wooden shish – window trap in both seasons.
