[ecological effect of the social behavior in two elasmucha species (heteroptera: insecta)].	in elasmucha grisea and e. fieberi we have confirmed parental care with a high effectiveness; in e. fieberi this behavior was still unknown. two years of investigations revealed that a loss in the progeny was diminished during the egg stage by the defence behavior of the female, in 1972 from 92% to 9% and in 1974 from 81% to 4%. because the 9% and 4% are not caused by external influences that can be eliminated by parental care, the effect of the defence behavior of the female amounts to about 10 ...	1975	28308789
ovary structure in a presocial insect, elasmucha grisea (heteroptera, acanthosomatidae).	first generation egg clusters of elasmucha grisea are more closely guarded than second generation clusters. the ovaries of this species are structured to enhance this behavior. the population of e. grisea from s-w poland breeds in the spring (may-june) and late summer (july-august). the second generation clutches contain fewer eggs and are destroyed 3-4 days after oviposition by predators and parasitoids. the ovary structure in the studied species differs from that found in other heteroptera. th ...	2009	19682601
