Abstract

The predation activity of larvae and adult of Oenopia conglobata (L.) as apredator of APHIDs and psyllids of forest, fruit and crop plants has been reported from the most regions of Iran. In order to determine the BIOLOGY of this .lady beetle on POPLAR APHID CHAITOPHORUS LEUCOMELAS (Koch) in LABORATORY CONDITIONS, different developmental stages from the first reared generations were selected and were separately kept in petri dishes. Egg incubation ,larval, prepupa and pupae developmental periods were daily registered. Six pairs of lady beetle were selected for determing rate of egg oviposition, pattern of oviposition and adult feeding rate from this APHID. These insects reared in the growth chamber. All of the experiments were performed under temperature 25, with RH 65 ± 5 %, 14/ 10h.(L/D)periods with feeding upon POPLAR APHID. The results of the experiment showed that mean of developmental periods from egg to adult emergence were 2.2± 0.08,2.4± 0.03,2.33 ± 0.03, 2.13 ± 0.03,4.4 ± 0.03, 1.6± 0.01 and 4.53 ± 0.03 days. Mean of daily oviposition and total of egg laying female adult were 25.24 ± 0.79 and 1435± 51.2 numbers. Mean of daily feeding for 1-4 larvae instars and female adults were 9.09± 0.38,22.87 ± 0.44,37.57± 0.75, 52.71± 63 and 36.19±0.47 numbers.
