Overexpression of poplar wounding-inducible genes in Arabidopsis caused improved resistance against Helicoverpa armigera (Hübner) larvae
Four highly inducible genes of poplar trees, PtdKTI5, PtdWIN4, PtdPOP3 from hybrid poplar (Populus trichocarpa × P. deltoides) and PtKTI2 from trembling aspen (Populus tremuloides Michx.) have been individually transformed into Arabidopsis thaliana for overexpression. High transcriptional level of each transgene in transgenic Arabidopsis lines was confirmed by RT-PCR analysis. The development, ...
متن کاملبرآورد سطح زیان اقتصادی (EIL) کرم قوزه پنبه Helicoverpa armigera Hb. (Lep., Noctuidae) روی پنبه
سطح زیان اقتصادی کرم قوزه پنبه Helicoverpa armigera Hb. روی پنبه رقم ساحل طی سالهای 1378-1379در گرگان مورد ارزیابی قرار گرفت. در این آزمایشات سطوح آلودگی0، 2، 3، 4، 6 و 8 لارو ریز کرم قوزه پنبه به‌ازای صد اندام زایشی، در سه نسل آفت، با رهاسازی آنها روی بوته‌های پنبه در مزرعه مطالعه گردید. اختلاف آماری معنی‌دار بین عملکرد در تیمارهای مورد بررسی در کلیه نسلها مشاهده شد. در نسل اول سطح...
متن کاملASSESSING Bemisia tabaci (GENN.) BIOTYPE B RESISTANCE IN SOYBEAN GENOTYPES: ANTIXENOSIS AND ANTIBIOSIS
Since it was first reported in Brazil in the 1990s, the B biotype of silverleaf whitefly (Bemisia tabaci [Genn.], Hemiptera: Aleyrodidae) has been recognized as an important pest in soybeans (Glycine max L.), reducing the productivity of this legume species in some areas of the country. As an alternative to chemical control, the use of resistant genotypes represents an important tool for integr...
متن کاملEfficacy of Some Insecticides Against Whitefly (Bemisia tabaci Genn.) Infesting Cotton under Field Conditions
Seven insecticides, viz. Megamos 20SL, Actara 25WG, Polo 500SC, Sitara 25WP, Nighaban 20EC, Thiodan 35EC and Confidor 200SL were evaluated at their field recommended doses for their efficacy against whitefly (Bemisia tabaci Genn.) on cotton, at the farmer’s field in Dera Ghazi Khan during 2007. The insecticides were applied at ETL’s of whitefly. All the test insecticides caused significant mort...
متن کاملResistance of soybean genotypes to Bemisia tabaci (Genn.) Biotype B (Hemiptera: Aleyrodidae).
The silverleaf whitefly Bemisia tabaci (Genn.) biotype B has become a serious problem for soybean cultivation because it can significantly reduce soybean productivity. The use of soybean cultivars resistant to whitefly attack is an important strategy in an integrated pest management (IPM) program. This study evaluated the preference for oviposition and colonization by B. tabaci biotype B on dif...
