Diamondback moth, Plutella xylostella (L.), resistance management in Hawaii

Resistance to spinosad insecticide in field populations of diamondback moth was discovered at Kunia, Hawaii, in November 2000, about two and a half years after its introduction. Leaf-dip assays of field populations from the islands of Oahu, Maui and Hawaii confirmed moderate to high levels of resistance compared with pre-introduction baselines. Resistance occurred despite label restrictions tha...

بررسی تأثیر چند حشره کش شیمیایی و بیولوژیک در کنترل شب پره پشت الماسی کلم Plutella xylostella L. (Lep.: Plutellidae)

استفاده از روش نابارورسازی حشرات در کنترل شب پره پشت الماسی کلم،Plutella xylostella L. (Lepidoptera: Plutellidae)

چکیده شب پره­ی پشت الماسی کلم،Plutella xylostella L. ، در حال حاضر یکی از جدی‌ترین آفات گیاهان تیره چلیپائیان در کشور است. لاروهای این حشره با تغذیه از برگ‌ها سبب خسارت این گیاهان می‌شوند. در مطالعه­­ ی حاضر امکان استفاده از روش عقیم سازی شب پره پشت الماسی توسط پرتوهای یونیزان مورد بررسی قرار گرفت. در این مطالعه اثر دزهای متفاوت پرتوی گاما در محدوده 100 تا 300 گری روی پارامترهای زیستی این شب پر...

Insecticide Resistance in Plutella xylostella (L.) (Lepidoptera: Yponomeutidae) in the Federal District, Brazil

The levels of resistance to the insecticides cartap, deltamethrin and metamidophos were evaluated for three populations of the Diamondback Moth Plutella xylostella (L.) from the Federal District, Brazil in laboratory bioassays. The larvae of DBM showed levels of resistance to deltamethrin between 4 and 47 fold relative to a susceptible laboratory strain. The level of resistance to metamidophos ...

Development of genetic markers to study dispersal of Diamondback moth, Plutella xylostella (L.) in Australia

The origin and insecticide resistance status of Diamondback moth (Plutella xylostella) populations infesting canola, vegetables, forage brassicas and weeds has fundamental implications for management of the pest in Australia. Diamondback moth is considered a migratory species in the Northern Hemisphere, but although there is evidence that Diamondback moth moves en-masse throughout Australia in ...

Laboratory Evaluation of Commercial Trichogrammatid Products for Potential Use against Plutella xylostella (L.) (Lepidoptera: Plutellidae)

In laboratory experiments we compared the mortality of Plutella xylostella L. eggs induced by six products of trichogrammatid egg parasitoids. Five of the species were commercially available, and the sixth is under development. Each of the six products represented a single species of trichogrammatid (Trichogrammatoidea bactraeNagaraja,Trichogrammapretiosum Riley, T. ostriniae Pan & Chen, T. pla...
