Ecological Management Of The Alfalfa Leafcutter Bee, Megachile Pacifica (Panzer), With Emphasis On Diapause Induction, Ron M. Bitner
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The effects of photoperiod and temperature on diapause induction in the alfalfa leafcutter bee, Megachile pacifica (Panzer) (=M. rotundata Auct.), were studied during the summers of 1972, 1973 and 1974, The influence of photoperiod and temperature on mortality, rate of development and incidence of diapause was measured during the developmental stages of this insect. The aim of this research was to assess the potential for manipulation of the number of generations of this bee per season so as to develop a practical and ecologically-sound method of management,
Eggs, larvae, pupae and adults of M. pacifica were subjected to regimens …
