Temperature-dependent development of Chilocorus bipustulatus (L.) (Coleoptera: Coccinellidae) on Aspidiotus nerii Bouché (Hemiptera: Diaspididae) under laboratory conditions
Turkish Journal of Entomology 37 (2), 185-194
Abstract: Chilocorus bipustulatus (L.) is an important predator of scale insects that is widely distributed in citrus plantations in the Mediterranean Region of Turkey. The developmental time of C. bipustulatus, a polyphagous predator, was studied at six different, constant temperatures (14, 18, 22, 26, 30 and 34°C) and a relative humidity (R.H. of 65±1%, with Aspidiotus nerii Bouché (Hemiptera: Diaspididae) as the prey. The developmental periods of immature stages were 61.67, 51.00, 41.21, 33.72, 26.76 and 27.17 days at 14, 18, 22, 26, 30 and 34 °C, respectively. The developmental threshold for C. bipustulatus determined with the linear model was 5.91. Linear regression was employed to determine the thermal constant of 651.1 degree-days.In this study linear and nonlinear regression models are discussed.
