A Synthesis of Temperature Dependent Developmental Studies with the Citrus Red Mite, Panonychus Citri (McGregor) (Acari: Tetranychidae)
Abstract
A literature review revealed 12 temperature-humidity studies performed on the citrus red mite, Panonychus citri (McGregor) (Acari: Tetranychidae). An analysis of these studies using a heat unit scale indicated that they were in surprisingly close agreement especially in view of the different host plants and experimental techniques utilized. Theoretical thresholds for development, degree days necessary to complete development, and temperature dependent mortality for the egg, immature and adult female stages are presented. This synthesis implies that further research with the citrus red mite is needed in the area of variable temperature developmental rates, fecundity and mortality rates.Downloads
