In recent years the use of agrochemicals, often referred to as pesticides, has become an increasingly controversial topic.

Well to satisfy everyones's curiosity, r will answer the question straight away. Yes, we can survive resistance! However, in answering it, I shall put another, perhaps even more thought provoking than the first.

Although resistance to insecticides was a well-documented phenomenon, pest control operators have merely switched from less effective insecticides to newer more potent compounds and thereby kept ahead of the resistanc

As major pests of cotton production, Heliothis spp. are of most concern to growers during the summer when they are active and damaging crops. Once autumn arrives and the crop is picked, Heliothis are soon forgotten.

The Cotton Council has been funding our project, for which we intend to identify cotton varieties with efficiency of dry matter production when irrigation is expensive, or relatively inexpensive.

One of the important characteristics elevating Heliothis spp. to major pest status is the ability to enter facultative diapause.

The two-spotted spider mite, Tetranychus urticae, ranks second to Heliothis in importance as a pest of cotton. Mites reduce profitability by reducing the yield and fibre quality of cotton.

Yield responses to increasing amounts of irrigation water have been demonstrated in the past by individual trials. In these trials watering occured at varying deficits of soil moisture below field capacity .

My objective has been to construct life tables describing Heliothis egg and larval survival on the major crops of the Darling Downs over several seasons.

As most of you are aware, the Siratac Cotton Management Advisor computer program is being rewritten. There will be those amongst you who are unaware as to why this is being done.

Biological control represents one alternative to insecticides. The Cotton Research Council (CRC) has funded a project to study native egg parasites of Heliothis.

Most, if not all, entomologists involved in the development of cotton insect management systems agree that an essent1al part of a successful Integrated Pest Management (IPM) program is the ava;lability of an eff1cac1o

Irrigation scheduling in cotton using the water balance program WATERSCHED has been the subject of an extension development project in Queensland for two years. The project is funded by Cotton Research Council.

The study reported here concentrated. On these sap-suokinq bugs, which were reputed to damage seedling and early-squaring cotton

Insecticides can poison insects in many ways. Insecticides r...:an interfere with metabolic processes , of energy production, cuticular growth and hormone production.

Irrigation trials have been conducted at Byee over the last two seasons as part of a Statewide project funded by the Cotton Research Council.

BACILLUS THURINGIENSIS use as an insecticide for 25 years despite formidable competition from conventional insecticides is largely due to its safety and compatibility.

At the time of the initiation of the H.armigera resistance management strategy, there was a need to demonstrate that any increase in resistance was limited to crops sprayed with pyrethroids.

One such form is biological control, which relies on the use of natural pathogens and parasites to control the pest species.
