Abstract

Natural control agents of the satin moth,Leucoma salicis (L.) were examined in 2Populus grandidentata MICHAUX stands. Highest mortality occurred in overwintering larvae, with the causal agents 2 fungi,Paecilomyces sp. andHirsutella gigantea PETCH, a factor causing death symptomatic of a pathogen, the parasiteEupteromalis hemipterus (WALKER) and death from unknown causes. Mortality fromPaecilomyces sp. andE. hemipterus was reduced where overwintering sites were covered with burlap cloth. Parasites recovered from larvae and pupae included the braconidsApanteles melanoscelus (RATZEBURG) andMeteorus versicolor (WESMEAL), the ichneumonidCoccygomimus pedalis (CRESSON), the tachinidsCompsilura concinnata (MEIGEN),Carcelia laxifrons VILLENEUVE,Tachinomyia variata CURRAN, and the sarcophagidsSarcophaga aldrichi PARKER andAgria housei SHEWELL. Larval and pupal predators included the carabidCalosoma frigidum KIRBY, pentatomids, and birds, particularly black-billed cuckoos,Coccyzus erythrophthaimus (WILSON). Eggs were parasitized by the scelionidTelenomus prob.californicus ASHMEAD and the trichogrammidTrichogramma minutum (RILEY). Predators of adult satin moths included the hermit thrush,Hylocichla guttata (PALLAS), and pentatomid bugs.
