Abstract
Oil spills can result in significant damage to marine estuaries, rivers, lakes, wetlands, and shorelines. Electrospun nanofibers containing biosurfactant (ENFs) can be used to clean oil spills up and protect the environmental biology. Present work aimed to study the side-effects of prepared nanofibers on animal models. Screening of the prepared ECNFs on animals showed that three of them (PVA-5, PEO-1, and PEO-5) are safe to hepatic tissues and liver functions. Furthermore, oxidative stress did not change after using these nanofibers. The PVA-1 nanofibers, however, were found to cause major pathological changes in the liver tissue. In addition, PVA-1 nanofibers were proved to alter the total white blood count and the neutrophil percentages significantly in comparison to the control. In conclusion, PVA-5, PEO-1, and PEO-5 are safe to hepatic tissues and liver functions.

Abstract
An approach to eatablish IPM program for some sucking pests infesting garden beans plants was carried out in two successive seasons of 2004 and 2005 under field conditions in Alexandria, Egypt. The sucking pests included the aphid, Aphis craccivora Koch (Homoptera: Aphididae), the white fly, Bemisia tabaci Genn. (Homoptera: Aleyroidae) and the spider mite, Tetranychus urticae Koch Pymetrozine, thiamethoxam, carbosulfan, abamectin, azadirachtin and the detergent (Masrol 410) were tested for their efficacy in this study. Thiamethoxam, carbosulfan, and pymetrozine proved to be highly effective against Aphis craccivora Koch, while abamectin, azadirachtin, and the detergent (Masrol 410) provided a moderate effect. Moreover, thiamethoxam, pymetrozine, and abamectin showed remarkable efficacy against adults and immature stages of the whitefly, Bemisia tabaci. However, azadirachtin provided a moderate effect, while carbosulfan and detergent (Masrol 410) had no effect altogether on whiteflies. In addition, abamectin induced the highest toxicity effect against the red spider mite, Teteranychus urticae followed by azadirachtin and the detergent that provided moderate effects. IPM program could be achieved by using abamectin, pymetrozine and azadirachtin in a sequence pattern throughout the whole season. Furthermore, the performance of the used agrochemicals on certain nutritional elements of beans pods vr. Branco , i.e. nitrogen, phosphorus, potassium, iron, and magnesium were also studied with varied results.

Abstract
Field trails were conducted to determine the performance of three different sequences as a unique solution for the control of the leaf miner Liriomyza trifolii (Burgess) (Diptera: Agromyzidae) infesting garden beans (Phaseolus vulgaris L.) during the two successive seasons of 2004 and 2005. Furthermore, during the evaluation period, the side effect against the ectoparasite Diglyphus isaea (Walker) (Hymenoptera: Eulophidae) was put into consideration. Meanwhile, the comparative evaluation of the pesticides alone showed that abamectin and azadirachtin were highly effective against Liriomyza trifolii, while carbosulfan, pymetrozine and thiamethoxam provided to be of a moderate effect. Moreover, carbosulfan showed harmful effect to the larvae of the ectoparasite Diglyphus isaea (Walker), while abamectin and azadirachtin gave a moderate effect. Thiamethoxam and the the detergent (Masrol 410) had slight effect in this respect. The highly effective sequence among the sequences was abamectin, pymetrozine and azadirachtin, against Liriomyza trifolii (Burgess), with slight harmful effect on Diglyphus isaea (Walker). However the sequence of azadirachtin, pymetrozine and abamectin had a moderate effect on Liriomyza trifolii (Burgess) and exhibited a slight toxic effect on Diglyphus isaea (Walker). In contrast, the sequence of carbosulfan, thiamethoxam and pymetrozine was the least effective and represented a slight effect on Diglyphus isaea (Walker). From this study, it was concluded that abamectin, pymetrozine and azadirachtin sequence has proved to be a unique solution for the control of the leaf miner Liriomyza trifolii (Burgess) infesting garden beans (Phaseolus vulgaris L.) in Egypt.
