Development of Turgida turgida (Rudolphi, 1819) in the common field cricket (Acheta pennsylvanicus Burmeister)

Abstract

Several species of orthopterans and coleopterans were experimentally infected with Turgida turgida. The common field cricket, Acheta pennsylvanicus, was the most suitable host. Eggs of T. turgida usually hatched in the ileum of crickets. Larvae were observed in the wall of the ieum 4 h postinfection. Larvae became encapsulated in the gut wall and moulted twice. At 30 °C the first moult occurred 5 days and the second one 10 days after infection. Larvae are described in detail. The intensity of T. turgida in crickets could be augmented by challenge infections.
