Abstract
Field experiments were carried out at Sakha Agric. Res. Station Farm, Kafr El-Sheikh to evaluate certain kidney bean varieties (Pronco, French bean and Polesta) and two breeding lines( Fl hybrid and R1655 ) of bean, Phaseolus vulgaris L for their relative susceptibility to the spider mite, Tetranychus cucurbitacearum (Sayed) and the white fly, Bemisia tabaci (Genn.) on three varieties. during two successive seasons, 2008 and 2009 . Obtained data showed that T. cucurbitacearum recorded the highest numbers during the third week of July in the first season , while B. tabaci appeared its maximum in the fourth week of June. Meanwhile, in the second season the two pests recorded the highest number in the fourth week of July. The numbers of T. cucurbitacearum were higher than B. tabaci during the two study seasons. The population density of T. cucurbitacearum was higher in the first season than in the second one, while B. tabaci showed the reverse. Based on the mean number of the two study seasons, variety Polesta harbored significantly the highest population of T. cucurbitacearum followed by French bean and the breeding line Fl hybrid ,while R1655 was the lowest infested. The highest infestation with B. tabaci occurred on French bean while, Pronco and R1655 were the least infested. Regarding to the susceptibility degree to the two pests, varieties Polesta, French bean and breeding line Fl hyprid appeared susceptible. The variety Pronco appeared as low resistant and breeding line R1655 appeared as moderate resistant. Thus, the gained results should be taken into account in planning programs of integrated pest management in the bean fields.
