چکیده

موریانة ‌Silvestri Microcerotemes diversusمهم‌ترین و مخرب‌تـرین گونــه‌ موجود در استان  خوزستان می‌باشد. در این تحقیق اثـر سه غلظت (500،2500،5000 پی‌پی‌ام) آفت‌کش فنوکسی‌کارب برمیزان ذخایر پروتئین، چربی و کربوهیدرات در موریانه کارگر در شرایط آزمایشگاهی مورد بررسی قرارگرفت. میزان پروتئین، چربی، قند و گلیکوژن برحسب میلی‌گرم به گرم وزن تر بدن حشره تعیین شد. نتایج نشان داد از بین غلظت‌های مذکور، غلظت 5000 پی‌پی‌ام بیشترین تاثیر کاهشی را داشته است. به طوری که در این غلظت، میزان پروتئین51/45، چربی34/63 و محتوای انرژی 10/36 درصد کاهش یافت. همچنین میزان قند و گلیکوژن به ترتیب 20/37 و 04/17 درصد در این غلظت افزایش یافت. کاهش معنی‌دار منابع انرژی نشان دهنده تاثیر این آفت‌کش بر میزان محتوای انرژی و بقای موریانه است.

چکیده [English]

Microcerotermes diversus Silvesteri is the most destructive termite pest among subterranean termites in tropical and subtropical regions, including Khuzestan province. In this research, effect subletral concentrations of fenoxycarb (500, 2500 and 5000 ppm) were studied on protein, lipid and carbohydrates contents in termite workers under laboratory conditions. The protein, lipid, sugar and glycogen were determined in milligram per gram of fresh weight. The concentration of 500 ppm had the greatest effect on energy sources with decreases in the amount of protein by 45.51%, lipid 63.34%, and energy content 59.93% compared to the controls. Also amount of sugar 37.20% and glycogen 17.04 % increases compared to the controls. Reduction in the energy content due to fenoxycarb effect can reduce survivorship in the termite.
