Abstract

The temperature-dependent development of five psyllophagous ladybirds, Adalia bipunctata (L.), Coccinella undecimpunctata aegyptica (Reiche), Exochomus nigripennis (Erichson), Hippodamia variegata (Goeze), and Oenopia conglobata contaminata (Menetries) (Coleoptera: Coccinellidae), was studied on the common pistachio psylla, Agonoscena pistaciae Burckhardt and Lauterer (Hemiptera: Psyllidae), in the laboratory. The lower developmental thresholds for total development (egg to adult) of the predators ranged from 10.9 (O. c. contaminata) to 14°C (C. u. aegyptica). The lowest and highest degree-day (DD) requirement values for total development of the studied cocinellids were estimated for C. u. aegyptica (166.67 DD) and E. nigripennis (344.83 DD), respectively. The optimum temperature for development of the studied ladybirds, calculated using third-order polynomial and Lactin models, was in the range of 27.5–30°C. This study showed that all the five psyllophagous ladybirds successfully complete their development in a wide range of temperatures from 17.5 to 30°C, indicating their high potential for use in biological control programs against A. pistaciae.
