- Abstract
Chilocorus bipustulatus L. (Col.: Coccinellidae) is a predatory coccinellid with a wide geographical distribution. Biological control programs should have a good understanding of the capacity of a predator to kill the target prey. Therefore, the age-stage specific predation rate and functional response of C. bipustulatus feeding on Agonoscena pistaciae (Hem.: Psyllidae) were studied at 18, 25, and 32 °C (65 ± 5%RH and 16 L: 8D) to confirm its potential as a biological control agent of common pistachio psylla. The functional response at 18 and 25 °C were described by type II and type III at 32 °C. The estimated maximum attack rate (T/Th) was at 25 °C. Moreover, the highest net feeding (C0) was observed at 25 °C (3271.5 psyllids). This laboratory study, thus, suggested that the predatory coccinellid C. bipustulatus reacted to the rise of temperature by enhancing the predation rate on A. pistaciae.
