Induction and transmission of Bacillus thuringiensis tolerance in the flour moth Ephestia kuehniella.
The use of Bacillus thuringiensis (Bt) endotoxins to control insect vectors of human diseases and agricultural pests is threatened by the possible evolution of resistance in major pest species. In addition to high levels of resistance produced by receptor insensitivity (5, 16, 17), several cases of tolerance to low to medium levels of toxin have been reported in laboratory colonies of lepidopte...
متن کاملEffect of temperature and relative humidity on the cellular defense response of Ephestia kuehniella larvae fed Bacillus thuringiensis.
While maintained under all combinations of three temperatures and two RH, fifth instar larvae of the Mediterranean flour moth, Ephestia kuehniella were fed wheat treated with spores and crystals of Bacillus thuringiensis var. kurstaki. Larvae that had fed on wheat with the bacterial preparation contained higher concentrations of nodules in their haemocoel than did larvae fed on wheat without ba...
متن کاملimpact of pyriproxyfen and methoxyfenozide on hemocytes of the mediterranean flour moth, ephestia kuehniella (lepidoptera: pyralidae)
the mediterranean flour moth, ephestia kuehniella zeller, is one of the major pests in stored products worldwide. several problems assossiated with the use of conventional insecticides have strongly demonstrated the need for applying alternative safe compounds such as insect growth regulators (igrs). in the present study, growth regulating activity and hematological effects of pyriproxifen and ...
متن کاملHypervariable Bkm DNA Loci in a Moth, Ephestia kuehniella : Does Transposition Cause Restriction Fragment Length Polymorphism?
Bkm sequences, originally isolated from snake satellite DNA, are a component of eukaryote genomes with a preferential location on sex chromosomes. In the Ephestia genome, owing to the presence of only a few Bkm-positive BamHI restriction fragments and to extensive restriction fragment length polymorphisms between and within inbred strains, a genetic crossbreeding analysis was feasible. No sex l...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
