| Abstract: | Host larvae stung as eggs by parasitic wasps, Chelonus sp., precociously initiate metamorphosis during a preultimate larval stadium. This alteration in expression of the normal developmental programme was observed in pseudoparasitized larvae which, although stung, contained no living parasite at the time of the shift in the development pattern. Experiments were conducted to determine why some stung larvae become pseudoparasitized and to identify the source of the regulatory material. Pseudoparasitism arises, in part, by the death of young parasite larvae after exposure of the host to the regulatory material, and in part due to lack of insertion of an egg at oviposition. By using various techniques to kill the internal parasite at different stages of development, or to prevent insertion of a parasite egg into the host during oviposition by the adult female, it was determined that the adult female is the source of the regulatory material. |
