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. This study was undertaken to gain a better understanding of the biology and ecology of P. scutigera in order to suggest ways of improving current control strategies. The approach I adopted was that advocated by Clark et al. (1967), whereby the life system of a pest is studied in an attempt to recognize key factors which control its abundance.

Heliothis armigera and H. punctigera are serious pests of cotton in Australia. Control of Heliothis is currently dependent on insecticides. Levels of resistance to several of the major chemical groups of insecticides is sufficient to threaten the long ter

The application of the chemical technique developed in DAQ27L in determining the age of field collected adults of Pectinophora scutigera (pinkspotted bollworm).

To conduct a critical examination of the ACCT data from 1974/75 to 1985/86 and to learn more about the relative behaviour of cultivars over the testing sites and the effectiveness of location to evaluate cultivar differences.

Installation of a Halon gas fire suppression facility has been completed at a total cost of $12,970* including the linking of the warning system to the building's fire warning system. The fire suppression facility will eliminate risk of fire started within the computer room by the automatic release of Halon gas; the gas is inert and does not damage electronic equipment.
