تأثير درجات الحرارة على تكاثر من الفول الأسود Aphis fabae Scopli Homoptera : Aphididae تحت ظروف المختبر

Abstract EN

The effect of temperature on the reproduction of Aphis fabae Scop, was studied during the period of 1996/1997, at the Faculty of Agriculture, University of Jordan.

High temperature has a drastic effect on aphid fecundity, number of developed embryos, female and nymphal weight gained.

The optimum temperature for aphid growth and reproduction was 19°C, but aphid growth and reproduction did not differ significantly at 23°C and 25°C.

Above 25°C, a sharp decline in aphid growth and reproduction was recorded.

Results showed an inverse relationship between temperature and female fecundity, number of well developed embryos inside adult female, nymphal and female weight gained within the effective temperature range.
