This project investigated how key insect predators contribute to the suppression of the cotton bollworm, Helicoverpa armigera, in Australian cotton crops and explored the interaction between predator abundance and div

Scientific Exchange USA Scientist Dr Tom Sinclair (USDA/University of, Florida) to Narrabri, Following the International Crop Science Congress last year we were presented with a, unique opportunity to host internation

Soil biota communities are one of the most diverse groups of earth’s biota.

Fusarium wilt, caused by Fusarium oxysporum f. sp. vasinfectum (Fov), is a destructive disease of cotton (Gossypium hirsutum L) in almost all cotton producing countries of the world.

Cotton aphid (Aphis gossypii Glover) is a late season pest of cotton, with the potential to

reduce the value of lint by contaminating it with sticky honeydew secretions. Recently, cotton

To establish if the spider communities in cotton at different locations around Australia are similar, we sampled, using beatsheets and pitfall traps, over 4500 spiders from seven locations extending from the tropical

The significance of transgenic cotton in the pest control strategy adopted by the

Australian industry makes the management of resistance to the Cry1Ac toxin of Bacillus

The emergence of multiple resistance to insecticides in Helicoverpa populations has had a significant impact on the production of most major field crops in Australia.

In growing their crops Australian cotton farmers need to comply with Australian regulations.

This project examined how and when individual Helicoverpa armigera carrying a resistant allele (BX) were favoured in field-grown cotton, particularly on Ingard®.

Trichogramma limit pest damage to Ord River Irrigation Area (ORIA) cotton crops by killing the developing embryo of their insect host at the egg stage, effectively reducing the number of emergent pests ingesting trans

Temperature plays a critical and complicated role in the growth and development of cotton.

Cotton production in Central Queensland will continue to impose a unique set of challenges due to climate and it’s remoteness from other production areas.

Shielded sprayers have been widely and quickly adopted by cotton growers for weed control

in the inter-row. In the last three seasons, the increase in area sown to RoundUp Ready®

Genetic engineering to confer useful agronomic and fibre traits will lower the cost and time

required for producing improved cotton varieties and will promote environmentally-friendly

Helicoverpa spp. are arguably Australia’s most important insect pests, costing the

economy $200-300M annually. Significant advances in the management of

The research into aphid bio-control in cotton has documented the agents attacking cotton aphid in southern and central Queensland, and provided an indication of their relative importance.

Limitations on the availability of irrigation water in eastern Australia has created

interest in the possibility of re-establishing cotton in the Oof

It is evident from experience with the resistance of H.

Aims, * To co-ordinate the adoption of research into sound management, practices in the Gwydir Valley cotton-growing region., The position has contributed to this general aim through most extension, activities which a
