This study was initiated to quantify the impact of those predators commonly found in Australian cotton fields and thereby reveal the importance of the various predatory species in Helicoverpa pest management.

The aims of this trip were to initiate research on HaSV RNA designed to improve our ability to express insect viral genes in transgenic cotton, and to attend two important conferences relevant to the long-term biologi

Commissioned in November 1994, it was funded equally by the Cotton Research and Development Corporation (CRDC) and Sainty and Associates with a budget of $47 000 and the following work was undertaken: 1.

Aim of Travel: To participate in the Vlth International Co11oquium on Invertebrate Pathology and Microbial Control. The Colloquium also incorporated the Second International Conference on Bacillus thuringiensis

In March 1995 the Cotton Research and Development Corporation (CRDC) asked the Centre for International Economics to prepare a report on the cotton industry and its economic impact.

From this visit I gained: 1. A good overview of the state of agricultural soil mechanics worldwide. I was struck by the lack of direction and novelty in some of the work in this field.

Cotton plants expressing the CrylAc toxin from Bt are near to commercial release.

The objective of this study was to examine the distribution of tyre imposed stresses, soil displacements and soil mechanical properties as function of the soil surface geometry.

With CRDC permission, the travel award was transferred from Dr Skerritt to Ms A Hill, the diagnostics project leader; there was, however, not a change in itinerary.

The inaugural Australian Rural Leadership Program was conducted during 1993 and 1994.The rationale for this innovative concept was to form a strong bond between the 30participants, enrich their leadership capabilities

Project Objective: To provide the basis for improved crop and soil management in dryland cotton production systems by: 1. monitoring on-farm performance of cotton-based dryland cropping systems; 2.

Objectives of visit: To attend the 13th Conference of the International Soil Tillage Research Organization (ISTRO) and present paper entitled "Effect of soil preparation method and cotton-based cropping system on

In Australia, management of cotton pests is insecticide based.

The comparative advantage1 of cotton production was examined for three production systems in the United States and four production systems within Australia.

A paper was presented at the fourth international Trichogramma and other egg parasitoid conference titled 'Evaluating egg parasitoids for integrated pest management in Australian raingrown cotton.' Highlight

A growth disorder of cotton has been observed in irrigated cracking clay soils in fields at Galathera Creek, north of the Australian Cotton Research Institute (ACRI) for several years.

Two fields of cotton on two nearby farms in the Macquarie Valley of NSW which had different histories of weed management were studied to determine if weed seeds were being introduced via irrigation water.

This project aimed to continue the steady improvements in developing improved cotton varieties adapted to Australian growing conditions and markets

The aims of the CRDC project CSE 29C were: - to optimise the design of recombinant Helicoverpa viruses with increased insecticidal activity (Activities 1 and 2 of the overall program above), - to develop suitable larg

The aim of this study was to complete the development of a mirid feeding bioassay to facilitate screening and characterization of proteinaceous toxins.
