“…These results agree with the findings of Hegab 2001;Pherson et al, 2009 andAl-Habshy et al, 2011 who mentioned that soybean varieties greatly varied in their susceptibilities to homopterous insects. However, the differences in the susceptibility of soybean varieties to these insects between the first and second season may be due to the differences in the climatic factors and/or the abundance of the natural enemies as they play a great role in regulating the population density and seasonal abundance of insect species on soybean plants (Raupach et al,2002;Abd-Elsamad et al, 2011 andAl-Habshy, et al,2011). Thus, variety that exhibits resistance in one locality or environment may be susceptible in another, as certain environmental conditions influence fundamental physiological processes of the plant as well as the plant ( Kumar,1984 andMetcalf &Luckmann, 1975).…”

Pest resistant and tolerant crop varieties offer a major mean of pest control as it could be incorporated into integrated pest management programs to minimize the serious problems of insecticides. The current work was carried out at Sakha Agricultural Research Station Farm to evaluate the relative susceptibility of six soybean varieties (Crawford, Giza 21, Giza 22, Giza 111, H 30 and H 32) to infestation with the main piercing-sucking insects (whitefly, Bemisia tabaci Genn.; aphids, Aphis spp.; jassids, Empoasca spp. and green stink bug, Nezara viridula L.) during two soybean growing seasons;2009 and 2010. Data indicated that whitefly population was higher in the first season than in the second one on all the evaluated varieties, while the reverse was found for the other insects. Based on the mean number of the two successive seasons, Giza 111 significantly received the highest number of whitefly and jassids, followed by Giza 22, while Crawford and H 30 had the lowest whitefly and jassids density, respectively. Also, H 30 and Giza 111 significantly had higher number of aphids among the evaluated varieties. As for the green stink bug, the highest population was found on Giza 22, Crawford and Giza 111, while the lowest one was counted on Giza 21 and H 32. In respect to susceptibility degree, Giza 111, Giza 22 and H 32 appeared susceptible to whitefly and jassids, while Crawford and H 30 appeared moderately resistant to whitefly and jassids, respectively. Giza 111 and H 30 appeared susceptible to aphids, while the other varieties showed low resistance. Also, Giza22, Crawford and Giza111 appeared susceptible to the green bug, while Giza21 and H32 appeared as moderately resistant. Generally, it can be concluded that Giza111 was the highest infested variety with all the tested insects. On the other hand, Crawford was the least infested variety with the whitefly and aphids, while H30 was the least infested with jassids and the green stink bug.

olerant varieties to insect species represent one of the simplest and important methods of insect pest control to minimize the insecticide hazards. Therefore, susceptibility of five soybean varieties to infestation with some piercing-sucking insects: aphids, Aphis spp.; whitefly, Bemisia tabaci (Genn.) and leafhoppers, Empoasca spp. were evaluated at Sakha Agric. Res. Station Farm, Kafr El-Sheikh Governorate during 2016 and 2017 seasons. The obtained results showed significant differences in susceptibility between the tested soybean varieties to the mentioned insects for every season and from season to another. In general, the population density of whitefly and aphids were higher in the first season than the second one, while the reverse was found for leafhoppers.Based on the grand mean number of the two study seasons, variety Crawford was significantly the most infested variety to infestation with leafhoppers and aphids, while the least infested variety for aphids was Giza35 and for leafhoppers was Hybrid30. As for the whitefly, Giza35 significantly was the most infested variety, while Crawford was the least infested one. In respect to the resistance status of the tested varieties to the insects, Crawford and Hybrid30 showed susceptiblity to aphid infestation, while the other varieties exhibited low resistance. Giza111 and Giza35 appeared as susceptible for whitefly, Giza21 and Hybrid30 showed low resistance, while Crawford was moderately resistant. Concerning leafhoppers, Giza111 and Crawford were susceptible. Giza21 showed low resistance, while Hybrid30 was moderately resistant.
