Studies on the bionomics of Anthrenus verbasci Linnaeus and its control

Anthrenus verbasci Linnaeus produce a generation in one or two years in tbe Huaihe River Valley of Anhui Provioce, living through the winter as larvae at different ages. During the last ten days of April, some overwintering larvae turn into pupae whereas the otbers keep larva form through another winter. In the first and middle ten days of May, imagoes begin to eclose and produce eggs in latter half of the month, 4-45 eggs each female. In the first half of June, eggs are hatcbed. The larvae harm insect samples and everything stored. Under the normal temperature, the eggs last 19.7 days. larvae 5-7 months (except wintering time), pupae 13.8 days. The female ealsts 21.4 days and the male 16.3 days. The growth of various forms of this insect are vitally aeffected by food and temperature. They can be controlled by 15% parathion-methyl+trichlorphon put in the sample box.
