Egg production and survival of the citrus red mite on an artificial feeding system
1988
Hare, J Daniel | Bethke, James A.
An artificial feeding system was developed for the citrus red mite, Panonychus citri McGregor (Acari: Tetranychidae) to determine egg production and survival of adult female mites in response to various nutrient solutions. Egg production increased with increasing sugar concentration up to 20%, then declined. Autoclaved sodium caseinate was the most suitable nitrogen source examined, and egg production was highest on diet fractions containing 8% sodium caseinate, the highest concentration examined. Fecundity was higher when dietary nitrogen was provided entirely by protein than in whole or in part by free amino acids. Results are qualitatively similar to studies with Tetranychus urticae Koch, however optimal concentrations of major nutrients were ca. 4 to 10 times higher for P. citri than for T. urticae.
