Abstract

The tydeid mite H. anconai has an egg, one larval, and three nymphal stages. Each postlarval stage begins with a prolonged period of quiescence following apolysis and preceding ecdysis. Quiescent phases are approximately as long as active immature phases. After adult female ecdysis, there is a short preoviposition period followed by a long reproductive period, during which up to 66 eggs per female are laid. When ample food is present, most of the eggs are laid early in the reproductive period. Mean generation time (T) is 20.6 days at 24 °C and 11.8 days at 30 °C.
