Host associated genetic variations in whitefly, Bemisia tabaci (Genn.)
Genetic variability due to host plants was studied in whitefly, Bemisia tabaci (Genn.), populations that were collected from fields of different crops (cotton, brinjal, potato, tomato and soyabean) and a weed (Sida sp.), and maintained on their respective host plants for 12 generations. Comparative RAPD-PCR analysis of these populations led to identification of 85 different polymorphic bands or...
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 کاملتعیین بیوتیپ‌های سفیدبالک پنبه Bemisia tabaci (Genn.)، در استان فارس
سفیدبالک پنبه (Bemisia tabaci) گونه‌ای مرکب و پیچیده با بیش از 20 بیوتیپ شناخته‌شده در جهان است. به منظور تعیین بیوتیپ‌های این آفت در استان فارس از جمعیت‌های سفیدبالک مزارع پنبه و فلفل در شیراز، کفترک، مهارلو، فسا و خیر استهبان طی سال‌های 1389-1388 نمونه‌برداری شد. بر اساس داده‌های آزمون RAPD-PCR الگوی بیشتر نمونه‌های B. tabaci با الگوی بیوتیپ B مطابقت داشت. الگوی بیوتیپ Cv نیز مشاهده شد و الگو...
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 کاملGenetic diversity of Bemisia tabaci (Genn.) Populations in Brazil revealed by RAPD markers
Bemisia tabaci (Genn.) was considered a secondary pest in Brazil until 1990, despite being an efficient geminivirus vector in beans and soybean. In 1991, a new biotype, known as B. tabaci B biotype (=B. argentifolii) was detected attacking weed plants and causing phytotoxic problems in Cucurbitaceae. Nowadays, B. tabaci is considered one of the most damaging whitefly pests in agricultural syste...
