Abstract:During the growing season of 1951 observations were made on the biology of the four-spotted fungus beetle, Glischrochilus q, quadringnatus (Say). Overwintering sites, emergence, mating, oviposition and larval habitats were observed. Simultaneous population estimates of adult beetles and of larvae of the European corn borer, Ostrinia nubilalis (Hübn.), were made in early sweet corn.
Adult beetles of the first generation emerged and moved to corn fields coincident with the beginning of stalk invasion by half-grown borer larvae, Beetles congregated in borer tunnels and exerted a reductive effect on borer populations. This reduction was estimated at 17% of those larvae reaching the third instar or about 8% of the initial population. This reduction is believed to be caused by mechanical injury with subsequent direct attack on weakened or moribund larvae. Other species of the genus Glischrochilus have been reported as predators on eggs and larvae of various bark beetles in England and in the United States.
