چکیده

در پژوهش حاضر، تأثیرغلظت‌های زیرکشنده (LC10 = 255, LC20 = 3702 and LC30 = 25461 conidia/ml) قارچ بیمارگر Beauveria bassiana Bals. (Vuill.) بر ویژگی­های زیستی شته جالیز، Aphis gossypii Glover، در شرایط آزمایشگاهی با دمای 1±25 درجه سلسیوس، رطوبت نسبی 5±65 درصد و دوره نوری 16 ساعت روشنایی با استفاده از روش تجزیه جدول زندگی دو جنسی ویژه سن-مرحله‌ رشدی مورد بررسی قرار گرفت. بر اساس نتایج به‌دست آمده، اگرچه غلظت‌های مورد مطالعه اثرات معنی‌داری بر طول عمر شته­های بالغ نداشتند، اما با افزایش غلظت، میزان باروری به‌صورت معنی‌داری افزایش یافت. علاوه بر افراد تیمار شده، نتاج آن‌ها نیز تحت تأثیر غلظت‌های مورد مطالعه قرار گرفتند.کم­ترین طول دوره رشد و نمو مراحل نابالغ در غلظت زیرکشنده LC30 مشاهده شد (36/4 روز). علاوه بر این، کم­ترین طول دوره قبل از تخم­ریزی کل (TPOP) نیز در این تیمار به‌دست آمد (60/4 روز). مرگ و میر مراحل نابالغ شته جالیز نیز با افزایش غلظت­های مورد مطالعه افزایش یافت و بیش­ترین درصد مرگ و میر در غلظت زیرکشنده LC30 ثبت شد (24/24 درصد). تیمارهای مختلف مورد مطالعه اثرات معنی‌داری بر نرخ­ ذاتی افزایش جمعیت (r) و نرخ متناهی افزایش جمعیت (λ) شته جالیز داشتند. نتایج حاصل از پژوهش حاضر می‌تواند به‌منظور افزایش میزان کارایی قارچ‌های بیمارگر حشرات در برنامه‌های مدیریتی آفات مختلف مورد استفاده قرار گیرد.

چکیده [English]

In the present study, sublethal effects (LC10 = 255, LC20 = 3702 and LC30 = 25461 conidia/ml) of entomopathogenic fungus, Beauveria bassiana Bals. (Vuill.) on the biological attributes of Cotton aphid, Aphis gossypii Glover, was evaluated under laboratory conditions (25 ± 1 °C, relative humidity of 65 ± 5% and a light period of 16 h.). Data analysis was performed using the Age-stage two sex life table theory. Based on the results obtained, although sublethal concentrations had no significant effects on the female longevity, but their effects on the fecundity of treated individuals was significant. In addition to the treated individuals, we also present data supporting that the sublethal effects could carry over to their offspring. The lowest recorded value for pre-adult development of A. gossypii was observed at LC30 (4.36 day). Furthermore, the lowest value for duration of total pre-ovipositional period (TPOP) was also recorded at this sublethal concentration (4.60 day). The highest mortality of immature stages was recorded at LC30 (24.24 %). Different treatments had significant effects on the intrinsic (r) and finite (λ) rates of increase. The results obtained could be helpful for increasing efficiency of entomopathogenic fungi in management programs of different pests.
