Abstract:

Dolycoris baccarum （L.） is a major pest of many crops at seedlings. In order to explore the in-laboratory artificial feeding technology, peanut, soybean and carrot were used as feed to study the effects of different feeds on development duration and adult survival rate. The results showed that there was no significant difference in the development duration between peanut and soybean fed insects, and they all developed into adults, with the adult survival rates being 80.53±3.16% and 75.03±2.89% respectively. When fed with carrot, D. baccarum could not develop into adult, and the survival rate was 0. There was no significant difference in development duration and adult survival rate between insects fed with single peanut and those with combined soybean, nor combined carrot. Thus using peanut and soybean as feed could raise D. baccarum artificially in laboratory.

Key words: Dolycoris baccarum （L.）, feeding, growth and development, peanut, soybean, carrot
