Abstract
Trial No. 88WH58
Doublegee demography in cereal crops.
Objective: To measure reproductive output in relation to times of emergence and herbicide application.
Trial No. 88WH10
Growth of doublegee under summer irrigation.
Objectives: A major impediment to achieving biological control of any annual weed in the wheat belt is that the bicontrol agent must have a means of aestivation. Since the only insect to have been introduced to Australia for a the control of doublegee does not aestivate, it was thought that populations could be able to oversummer in irrigated doublegee standards. The aim of this study was to assess the growth of doublegee out of season.
