oa Journal of the Entomological Society of Southern Africa - Modifications to an existing laboratory rearing technique for Heliothis armigera (Hubn) : Scientitlc Note



Few insects can be mass reared in a laboratory without encountering problems. Difficulty is usually encountered in rearing the American bollworm (Heliothis armigera) in the laboratory because of the cannabalistic tendency of the larvae, their susceptability to disease, and unreliable oviposition. Reported herein are some modifications effected to the method descriptionbed by Bot (1966) which were found to be satisfactory, allowing a colony to be bred for four years without difficulty.
