Book Description
Excerpt from A Study in Hyperparasitism, With Particular Reference to the Parasites of Apanteles Melanoscelus (Ratzeburg) All the species that appeared to be of any importance as enemies Of this Apanteles have been studied more or less in the laboratory. They have been allowed to oviposit in cocoons of Apanteles, and vari ous points in their development and behavior have been determined. It was necessary to have available a considerable number of cocoons that were known to be parasite-free. These Were Obtained by subj ect ing gipsy-moth larvae to attack by Apanteles and then rearing these caterpillars in covered trays until the Apanteles larvae emerged to spin their cocoons.
