Impact of Nosema pyrausta (Microsporida: Nosematidae) on a predator, Chrysoperla carnea (Neuroptera: Chrysopidae)
Environmental Entomology 18 (1), 172-176
Abstract: Chrysoperla carnea (Stephens) larvae fed Nosema pyrausta (Paillot)-infected Ostrinia nubilalis (Hübner) eggs developed normally and produced adults with unimpaired fecundity, fertility, and longevity. The microsporidium evidently failed to cause any infection in C. carnea. The ingested spores remained in the midgut throughout the larval feeding period and were eliminated in meconium during imaginal eclosion. These spores, which had been within C. carnea for at least 7 d, remained infective in bioassays against O. nubilalis larvae. In nature, this general insect predator may suppress O. nubilalis not only by predationbut also by dispersing microsporidian spores. Furthermore, C. carnea and N. pyrausta are compatible entities to be utilized in a pest management program.
