Aphidius avenea Haliday is the predominant species of the parasitic natural enemies of wheat aphids in Linqing City, accounting for 4/5 of the 5 kinds of aphid bees in wheat fields. The author from 1978 to 1989 on its biological characteristics and growth and decline of the law conducted a survey and indoor feeding observations. The results reported to the next. First, the material and methods in autumn and early spring in the wheat field, oil field, winter Tibetan cabbage, Spinach and other crops collected aphids and stiff aphids, identification of aphid Braconidae species, understand the overwintering state, and placed indoor and outdoor mortality; 3 to June in the wheat field every 10 days to collect a number of stiff aphids, observed emergence rate, insect species , Shriveled, heavy parasites; field system to investigate one or two types of wheat field 100 100 once a day; potted
