The pests are (1) the bollworm, Helicoverpa zea (Boddie) and tobacco budworm, Heliothis virescens (F.), (2)_the boll weevil, Anthonomus grandis grandis (Boheman), (3) the pink bollworm, Pectinophora gossypiella (Saunders) and (4) plant bugs, specifically Lygus spp. Rearing of the predators and parasitoids and identification and the use of behaviour-modifying chemicals are described and discussed.
