Objectives The dynamics of beneficial insect communities in cotton agroecosystems and the role of alternative crops in producing natural enemies for cotton * To quantify the seasonal phenology and abundance of key ben

The aim of the present work is to assess the usefulness of pteridines in determining the age of adults of P. scutigera.

Despite it's status as a pest of cotton (Gossypium hirsutum L.) in Central Queensland, the biology and ecology of the pink-spotted bollworm, Pectinophora scutigera (Holdaway), is poorly understood.

Traps baited with sex attractants ( 1 pheromone 1 traps) are presently being used by a number of farmers in Central Queensland to monitor P. scutigera populations and for timing insecticide sprays.
