dc.description.abstract In Australia, about 85% of cotton farmers grows transgenic (Bt) cotton. Bt cotton controls only Lepidopteran pests but is not effective against sucking pests. Control of these pests and also b Helicoverpa spp. in conventional and Helicoverpa survivors on transgenic cotton crops relies extensively on the use of synthetic insecticides. The issues of cost, efficacy, resistance and environmental impacts have led to the increased implementation of Integrated Pest Management (IPM) programs. Crop plants including cotton can produce secondary plant compounds (SPCs) to protect the plants against pest predation. The SPCs can modify pest behaviour by acting as feeding and oviposition deterrents, attractants or repellents to reduce pest damage. Toxicity of SPCs are not as high as synthetic insecticides but when this toxicity is added to the other effect of SPCs their combined efficacy against the pest is high. For the past 6 years, research by NSWDPI has identified a plant codenamed Plant X. Fractionated extracts from the plant in Hexane and oil has been found to deter pest feeding, egg lay and cause toxicity to larvae and nymphs of cotton pests. Generally, Plant X has intuitive appeal because the product can be used in IPM as a stand alone or reduced label rates of synthetic insecticides to reduce Synthetic insecticide sprays
