چکیده

شب‌پره هندی، (Lep.:Pyralidae)   Plodia interpunctellaیکی از آفات انباری انجیر در مناطق اصلی کاشت انجیر در ایران می­باشد. در این تحقیق برخی ویژگی­های زیستی آفت در دماهای 15، 20، 25، 30، 35 درجه سلسیوس با شرایط نوری 16:8و رطوبت نسبی 5±60% مورد مطالعه قرار گرفت. به طور میانگین دوره جنینی در دماهای ذکر شده به ترتیب برابر با 44/14، 70/6، 27/3، 30/3، 26/4 روز، میانگین طول کل دوره لاروی به ترتیب برابر با 79/70، 60/42، 61/34، 2/32، 77/27روز، میانگین طول دوره پیش شفیرگی به ترتیب برابر با 9، 36/4، 44/1، 31/1، 23/1 روز و میانگین طول دوره شفیرگی برابر با 92/15، 44/12، 29/7، 77/5، 34/3 روز به دست آمد. میانگین طول عمر حشره­های بالغ ماده به ترتیب برابر با 05/13، 38/12، 12/8، 65/7، 73/6 روز و طول عمر حشره­های بالغ نر نیز به ترتیب برابر با 62/13، 37/13، 7، 03/7، 33/6 روز بود. بر اساس نتایج حاصله به دست آمده،  بر اساس مقایسه میانگین به دست آمده دماهای پایین­تر باعث کند شدن رشد و نمو و دماهای بالاتر باعث کوتاه­تر شده طول مدت رشد و نمو گردید.

چکیده [English]

Indian meal moth Plodia interpunctella, (Lep.: Pyralidae)  is one of the main pests of  stored figs  in Iran. The effects of different temperatures (15, 20, 25, 30, 35° C) on the biological characteristics of this pest at laboratory conditions (16:8 L:D , 60±5 % Rh) on dried fig were studied . Mean incubation period were estimated 14.44, 6.70, 3.27, 3.30, 4.26 days respectively. Total larval developmental time were determined 70.79, 42.60, 34.61, 32.2, 27.77 days and duration of pre-pupal and  pupal stages were estimated 9, 4.36, 1.44, 1.31, 1.23 and 15.92, 12.44, 7.29, 5.77, 3.34 respectively. Mean adult longevity were estimated 12.62, 12.38, 7.04, 7.65, 6.73 for female and 14, 12.37, 7, 7.03, 6.33 for parameters. Developmental rate were highest on 35° C. The result showed that high temperature promote rapid development of P. interpunctella on dried figs.
