Effect of Temperature on Development and Survival of<i>Citrostichus phyllocnistoides</i>(Hymenoptera: Eulophidae), a Parasitoid of<i>Phyllocnistis citrella</i>(Lepidoptera: Gracillariidae)

Abstract

Thermal requirements of Citrostichus phyllocnistoides under laboratory conditions resulted in a lower temperature threshold of 9.8°C, and a thermal constant of 212.0 DD. Development was completed between 15 and 30°C, but was not at 10°C. Therefore, the overwintering of this exotic biocontrol agent would be possible under typical Mediterranean temperatures.
