Simplistic diagram of your own biannual existence course off P. cimiciformis. Intimate breeding happens into the P. terebinthus woods, the first host, where as much as five additional morphs occur. Of these years, three build in to the distinctive line of galls which they trigger within their host’s will leave. On the the termination of summer, the last age group born in the galls consists of winged aphids you to definitely travel towards the root of many gramineous kinds, its second servers. Here, they initiate a sequence regarding supply-house wingless parthenogenetic years comprising two morphs: the fresh bullet (RM) in addition to apartment (FM) morphs, correspondingly.
