| Abstract | ||
| Field and Laboratory studies were conducted to evaluate the predation potency and population density of the predator Clitostethus arcuatus (Rossi) (Coccinellidae: Coleoptera) on jasmine white fly Aleuroclava jasmini Takahashi on Citrus. Establishment of laboratory culture of C. arcuatus was achieved by using eggs, movable nymphs and stationary nymphs of A. jasmini as food which is considered the main step of mass rearing, the average number of eggs and nymphs consumptive by the larva and adult of predator were recorded. Results indicated that larvae of C. arcuatus consumed an average of 966.2, 1050 and 460 of eggs, movable and stationary nymphs respectively during one week period. In addition, Adult predator consumed an average of 1451 eggs, 980 movable nymphs, 367 stationary nymphs and 115 adults during one week period. Predator potential as a part of pest management was discussed and results of this study can be used in the practical application of biological control to A. jasmini on citrus. | ||
