| Abstract | ||
| The role of the predator Orius albidipennis (Reut) (Hemiptera: Anthocoridae) in predation of white fly Aleuroclava jasmine (Takahashi), was examined under laboratory conditions. The result of white fly eggs predation showed that average consumption by single predator`s adult was 59.0 egg/day. This was continued for 10 days with no significant differences between first and last day. As well as the average consumption of predator`s adult were 10/day and 2.07/day of nymph and adult white fly respectively for the same period. The adult of the predator was able to consume 590 eggs, 102 nymph and 20.7 adult during the 10 days of the experiment. The result also showed that predator`s nymph consumed an average of 60, 68, 96, 132, 157 eggs of white fly during 1st., 2nd., 3rd., 4th. and 5th. instar respectively. The total consumption was 513 white fly eggs per nymph stage. | ||
