Abstract
Larvae of the alfalfa weevil, Hypera postica, were infected by an in v itro colony of Zoophthora phytonomi. Two spore types (infective conidi a, and resting spores) were produced from infection trials. The spore type produced may be influenced by the physiological state of the larv ae. Trials using field collected larvae which would produce diapausing adults formed both conidia and resting spores. Trials using larvae fr om a nondiapausing colony, however, formed only resting spores.
