Abstract

Two experiments were carried out to evaluate the effect of three constant temperatures (20, 25 and 30oC) and the influence of three photoperiods (14/10, 12/12 and 10/14 h. L/D) on the larval, pupal duration period and predation capacity of Chrysoperla carnea reared on Aphis carccivora. In the 1st experiment the obtained results showed that increasing of temperature resulted in decreasing in both larval and pupal durations period and reducing in the total numbers of consumed preys (A. carccivora). Results obtained in the 2nd experiment proved that the long larval duration was at long photoperiod 14/10 h. L/D). To the contrary, the highest numberd of consumed prey by C. carneu was achieved under short day (10/14 h. L/D).
