برخی گونه های سفیدبالکان از زیرخانواده aleyrodinae تنوع مرفولوژیکی وابسته به میزبان را نشان می دهند. در میان این گونه ها، عسلک پنبه bemisia tabaci (gennadius) طیف وسیعی از تنوع میزبانی را در جمعیت ها و بیوتیپ های خود نشان داده است. در این تحقیق، در طی سال های 85-1383 برگ های گیاهان میزبان (خیار، بادمجان، گوجه فرنگی و پنبه) آلوده به پوره و پوسته های شفیرگی از نقاط مختلف منطقه ورامین جمع آوری شد....
Bemisia tabaci, an invasive pest that causes crop damage worldwide, is a highly differentiated species complex, divided into biotypes that have mainly been defined based on mitochondrial DNA sequences. Although endosymbionts can potentially induce population differentiation, specialization and indirect selection on mtDNA, studies have largely ignored these influential passengers in B. tabaci, d...
The sweetpotato whitefly Bemisia tabaci (Gennadius) is one of the most invasive pest species worldwide. Q and B biotypes are the two most devastating species within the B. tabaci complex. Bemisia tabaci can vector hundreds of plant viruses that seriously threaten crop production. Endoparasitoid, Encarsia formosa Gahan, is widely used to control whiteflies, however, little is known about the eff...
The sweetpotato whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is a major pest of economically important crops worldwide. Both the United Kingdom (UK) and Finland hold Protected Zone status against this invasive pest. As a result B. tabaci entering these countries on plants and plant produce is subjected to a policy of eradication. The impact of B. tabaci entering, and becoming e...
Susceptibility of Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) to Different Insecticides under Water Hardness Condition and Additives
Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is a cryptic species complex that includes some of the most significant pests of agriculture and horticulture worldwide. To understand the diversity and distribution of B. tabaci cryptic species in Yunnan, a famous biodiversity hotspot in China, a large-scale sampling was conducted from year 2010 to 2013 in 10 prefectures. Mitochondrial cytoch...
"Candidatus Hamiltonella defensa" is a facultative endosymbiont of the whitefly Bemisia tabaci. Herein, we report the first draft genome sequence of "Candidatus Hamiltonella defensa" from the invasive Mediterranean cryptic species of the B. tabaci complex. The 1.84-Mbp genome sequence comprises 404 contigs and contains 1,806 predicted protein-coding genes.
The sweetpotato whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) continues to be a serious threat to crops worldwide. The UK holds Protected Zone status against this pest and, as a result, B. tabaci entering on plant material is subjected to a policy of eradication. There has recently been a shift from Middle East-Asia Minor 1 to the more chemical resistant Mediterranean species ent...
کاربرد سموم روی جمعیت آفات میتواند روی پارامترهای واکنش تابعی و بالطبع روی کارایی دشمن طبیعی اثر بگذارد. در این تحقیق اثرات دو حشرهکش ایمیداکلوپراید و بوپروفزین روی واکنش تابعی زنبور پارازیتوئیدEncarsia inaron (Walker) نسبت به تراکمهای مختلف پوره سن سه سفیدبالک پنبه (Gennadius)Bemisia tabaciدر شرایط آزمایشگاهی مورد بررسی قرار گرفت. پارازیتوئیدهای ماده جوان (طولعمر کمتر از 24 ساعت) به مدت 48...
Whiteflies, Bemisia tabaci (Gennadius) are major insect pests that affect many crops such as cassava, tomato, beans, cotton, cucurbits, potato, sweet potato, and ornamental crops. Bemisia tabaci transmits viral diseases, namely cassava mosaic and cassava brown streak diseases, which are the main constraints to cassava production, causing huge losses to many small-scale farmers. The aim of this ...
