Colonization of the winter cherry bug, Acanthocoris sordidus (Hemiptera: Coreidae)

The winter cherry bug, Acanthocoris sordidus, is distributed in Korea, Taiwan and Japan, and is known a pest of crops in Solanaceae and Convolvulaceae including pepper and sweet pepper in Korea. The winter cherry bug was seen that there is formed a colonization to both breeding in the laboratory and observing in the field. When forming or not the colonization, developmental characteristics and factors of colonization were investigated in the insect cages. When the winter cherry bug breeding with individual or colony, it had shown a lot of difference in their developmental phase. In his position, the formation of the colonization can be a great strategy to grow nymph, but if this does not form the colonization can be a factor that hinders the growth of nymph. In addition many insects can form the colonization using pheromones or plant volatiles. We investigated what are factors that may be used to colonization in case of the winter cherry bug using MS-GC and Y-tube olfactometer.
