LIFE TABLE, NUMERICAL AND FUNCTIONAL RESPONSE OF ADALIA BIPUNCTATA L. FEEDING ON CHAITOPHORUS LEUCOMEL4S KOCH. BEING A POPLAR PEST
Abstract
C.leucomelas is an important pest on the leaves of poplar trees in Van province . It has been observed during our survey studies that A.
A. bipunctata has fed on this aphid species. Hence, it was aimed in this study to reveal whether A. bipunctata is an effective predator against to C leucomelas. · .•' ·
Life table, numerical and functional response of A.bipunctata feed
with five different number individuals (4,8,16,32,64) of C. leucomelas taken daily from poplar trees were found . All experiments has beerH;onducted in
chamber conditions 25±1°C, %60±5 relative humiditY, 16/8 light period and in glass pots covered with a tent their round top .
It has been conduced that C I eucomelas is as a suitable food for A.
bipunctata. Briefly, it was not found any difference beetwen A. bipunctata feeding on 32 and 64 aphids, in view of the period of development stage and oviposition, also the daily number of laying eggs.They were found the net production rate(Ru) 374,78 female/female , the intrinstic rate of increase(rm) 0,21 female/female/da y and the generation mean time(T) 27,7 day.
