Macrolophus pygmaeus Rambur (Hemiptera: Miridae) is a generalist predatory mirid widely used in augmentative biological control of various insect pests in greenhouse tomato production in Europe, including the invasive tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera, Gelechiidae). However, its biocontrol efficacy often relies on the presence of alternative prey. The present study aimed at...

Enterococcus mundtii strains isolated from the larval feces of the Mediterranean flour moth Ephestia kuehniella show antimicrobial activity against a broad spectrum of Gram-positive and Gram-negative bacteria. The in vitro probiotic characterization of one isolate revealed a high auto-aggregation score, a hydrophilic cell surface, tolerance for low pH, no hemolytic activity, and susceptibility ...

ویژگی‌های زیستی به‌ویژه رفتار تخمریزی زنبورهای پارازیتویید یکی از مهم‌ترین عوامل تعیین‌کننده کارایی آنها در مدیریت جمعیت آفت میزبان می‌باشد. این مطالعه الگوی وابسته به سن، نرخ پارازیتیسم، درصد تفریخ و نسبت جنسی زنبور Trichogramma brassicae روی Ephestia kuehniella شرایط آزمایشگاهی (1±25 درجه سلسیوس، رطوبت نسبی %5±70 دوره نوری 16: 8 ساعت (روشنایی: تاریکی)) بررسی شد. نتایج نشان داد T. سنین جوانی (...

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...

A somatic transformation gene vector that exploits the genomic integration properties of Junonia coenia lepidopteran densovirus (JcDNV) sequences in vivo has been developed. JcDNV somatic transformation vectors are derivatives of plasmids containing an interrupted genome of JcDNV that provide efficient, robust vectors that can be used to examine regulation of chromosomally integrated transgenes...
