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...
متن کاملDemographic parameters of the diamondback moth, Plutella xylostella (Lep.: Plutellidae) on five rapeseed cultivars
شب‌پره‌ی پشت الماسی، (Plutella xylostella (L.) (Lep.:Plutellidae، یکی از مخرب‌ترین آفات گیاهان چلیپیان در سراسر دنیا است. در این تحقیق پارامتر‌های دموگرافیک این حشره روی پنج رقم کلزا شامل لیکورد، مودنا، اکاپی، RGsoo3و REGXkobra بررسی شد. آزمایش‌ها در اطاقک رشد با دمای 1±25 درجه‌ی سانتی‌گراد، رطوبت نسبی 5±60 درصد و دوره‌نوری 16 ساعت روشنایی و 8 ساعت تاریکی انجام شد. مرگ و میر مراحل قبل از بل...
متن کاملParasitoids associated with the diamondback moth, Plutella xylostella (L.), in the Eastern Cape, South Africa
Seasonal fluctuations of diamondback moth and its hymenopteran parasitoids were recorded weekly from April 1997 to November 1999 at four cabbage sites in the Grahamstown area of the Eastern Cape, South Africa. Two sites were commercial farms with active spraying programmes; the others were unsprayed. Infestation levels were highest during spring (September to November) and autumn (March to May)...
متن کاملCharacterization and expression of the cytochrome P450 gene family in diamondback moth, Plutella xylostella (L.)
Cytochrome P450 monooxygenases are present in almost all organisms and can play vital roles in hormone regulation, metabolism of xenobiotics and in biosynthesis or inactivation of endogenous compounds. In the present study, a genome-wide approach was used to identify and analyze the P450 gene family of diamondback moth, Plutella xylostella, a destructive worldwide pest of cruciferous crops. We ...
متن کاملGenome-wide characterization and expression profiling of immune genes in the diamondback moth, Plutella xylostella (L.)
The diamondback moth, Plutella xylostella (L.), is a destructive pest that attacks cruciferous crops worldwide. Immune responses are important for interactions between insects and pathogens and information on these underpins the development of strategies for biocontrol-based pest management. Little, however, is known about immune genes and their regulation patterns in P. xylostella. A total of ...
