Determining the impact of species considered potentially important natural enemies of crop pests is crucial for making robust management decisions as part of an IPM programme (Ives 1980; Johnson et al.

Temperature plays many important roles in the growth and development of cotton.

Many beneficial arthropods exhibit life-history omnivory (Polis & Strong 1996), in that they include honeydew, floral nectar, extra-floral nectar and/or pollen in their immature or adult diet (Hagen 1986; Coll

Fusarium wilt is an economically important disease of cotton in Australia. Disease occurs at the intersection of pathogen, plant, and environment (Figure I).

Cold shock at temperatures below 11C was previously believed to delay cotton development. This paper tested whether exposure to 10C for 10 and 20 nights affected tissue viability.

There appears to have been a change in the importance of pests presenting cotton over the last decade. This has involved former secondary pests, such as aphids, A. gossypii, minds, Creontiodes spp.

Resistance in the cotton aphid (Aphis gossypii) is a major new threat to Australian cotton production (Herron et al. 2001).

It was May of 1984 while living in Japan; I received a call that our company had bought George H. MCFadden Co. I was told we had a 50% ownership in a gin in Australia and I was to go check it out ASAP.

There is increasing interest in utilising Trichogramma egg parasitoids against helothis(Helicoverpa spp. ) in cotton, and crops that may act as sources of parasitoids for cotton -such as sorghum.

Groundwater, under the right conditions can be of benefit to plants. For example, cotton can derive substantial water from groundwater at depths of around 2.6m (Wanender et al 1979).

The results of annual disease surveys continue to indicate the importance of soil-borne plant pathogens. Seedling diseases are controlled by the use of fungicide seed treatments.

Changes to the cotton farming system over the last decade have caused a change in the weed spectrum, favouring glyphosate tolerant, smallseeded, biannual and perennial weeds.

Australian cotton is viewed worldwide as a quality fibre and generally performs as expected.

Trichogramma pretiosum is a key natural enemy of heliothis (Helicoverpa spp. ) on the Darling Downs. The data presented here describe some of the biological parameters of T.

Bollgard II is simply cotton with better control of Helicoverpa and the same principles of management apply to Bollgard II as for conventional cotton.

Water for irrigation is the limiting resource for cotton production in Australia.

Airborne volatiles emitted by flowers and other vegetative plant parts that attract insects for feeding and egg-laying could be useful in pest management.

Trichogramma pretiosum Riley is an important parasitoid of heliothis (Helicoverpa spp.) eggs throughout the Darling Downs.

Typically the fungus Thielaviopsis basicola, the casual organism for black root rot, is generally considered to be widespread in both cultivated and uncultivated soils; surveys were conducted in the catchments surroun

Sicot F-1 is a new cotton variety released in 2004. It has been developed specifically in response to the appearance of a new unique strain of the Fusarium wilt pathogen in Australia.
