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 (...

Olfactory sensory axons target well-defined intermediate targets in the zebrafish olfactory bulb called protoglomeruli well before they form odorant receptor-specific glomeruli. A subset of olfactory sensory neurons are labeled by expression of the or111-7:IRES: GAL4 transgene whose axons terminate in the central zone (CZ) protoglomerulus. Previous work has shown that some of these axons mispro...

The tooth structure preservation is the best way to postpone more invasive therapies. Especially in young patients more conservative techniques should be applied. Bonded porcelain veneers and even more the direct composite restorations, are the two therapeutic procedures that require the fewer sacrifice of dental tissue, finalized to the optimal recovery of aesthetic and functional outcome. Alt...
