Abstract

The southern pine coneworm, Dioryctria amatella (Hulst), (Lepidoptera: Pyralidae) is nocturnal and reproductive behavior occurs only during the last 5 h of scotophase (12L:12D photoperiod). Mating does not begin until moths are 2 days old and mating and oviposition are dependent on the presence of the host plant. Satisfactory rearing required surface sterilization of eggs with sodium hypochlorite, autoclaving the dietary wheat germ, inclusion of sorbic acid in the larval rearing medium, and a larval rearing density of no more than 2 per 30 ml container. The described methods have been used to rear more than 40 successive generations of the insect on the WGCS medium.
