(1990-08-08)The aim of this project was to develop a mass screening technique for the selection of cotton plant antibiosis resistance (AR) to H. armigera.
-
(1990-08-08)For a long time, pest control In the cotton industry has depended on a narrow range of broad-spectrum insecticides. However, because of increasing insecticide resistance, the future Is uncertain and alternatives are urgently ...

(1990-08-08)During the 1988/89 cotton season trials were conducted to evaluate the potential of synthetic pheromones to control the pink -spotted boll worm, Pectinophora scutigera, by mating disruption
-
(1990-08-08)A complex of pests attacks the Australian cotton crop, none more important than the cotton bollworm, Heliothis armigera. and insecticides are considered necessary for its control. H. armigera has a long history of insecticide ...
-
(1990-08-08)The Australian Field Crops Resistance Management Strategy has been in place now for 7 seasons. The impact of the Strategy on resistance levels is monitored in three areas; the Namoi and Gwydir river valleys of nonhem NSW ...

STUDIES OF THE ECOLOGY OF HELIOTHIS SPP. IN INLAND AUSTRALIA: WHAT RELEVANCE TO THE COTTON INDUSTRY? (1990-08-08)Heliothis spp. are clearly the major pests of Australian cotton and consequently there has been considerable research on their biology, ecology and control (Zalucki et al 1986). Most of this research has focused on Heliothis ...
-
(1990-08-08)An important question is the area of origin of these spring immigrants. Over the last 3 years, we have been investigating the ecology of Heliothis spp. in inland Australia (Gregg et al. 1987, 1989). The most recent findings ...
-
(1990-08-08)The pattern of flight activity within or between habitats or crops is dependent upon the distribution of those habitats/crops in both space and time. Similarly the pattern of movement of moths over large areas may be ...
-
(1990-08-08)Heliothis spp. are very successful as pests for a number of reasons (Fitt 1989): adult moths are highly mobile and have a high reproductive rate, larvae can utilize a wide range of host plants including most crops, and ...

(1990-08-08)The Bureau of Rural Resources has estimated the area in central Queensland potentially suitable for raingrown cotton production at 60-80,000 ha. With cotton prices above 1989$ 400 per bale, raingrown production can be ...
-
(1990-08-08)The purpose of our four-year study on the Darling Downs was 1) to investigate the population dynamics of heliothis and to quantify the significance of the major controlling influences (parasites, predators, pathogens, ...
-
(1990-08-08)The potential for extensive adult movements is one of the key factors contributing to the success of Heliothis spp. as pests (Farrow & Daly 1987, Fitt 1989). Adult movements may occur on several spatial scales; from one ...
