It is well-recognised that the pest status of Helicoverpa spp.

Helicoverpa punctigera, along with Helicoverpa armigera, are major pests in Australian cotton.

The resilience of a stacked Bt technology is determined by the efficacy of each individual toxin in controlling insects.

Insecticide resistance in the cotton bollworm Helicoverpa armigera has been one of the greatest limitations to successful pest control and economic cotton production in Australia.

The UQ35c twelve-month project continued on from the UQ32c research covering the Helicoverpa armigera microsatellite survey of field collections over twelve of the major cotton growing regions during the 2003-2004 sea

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

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.

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

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

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

Helicoverpa armigera shows a much higher tolerance than Heliothis virescens towards the Cry lAc toxin present in INGARD and BOLLGARD II cotton. Unlike H. virescens, the major pest of cotton in the USA, some H.

This project was based on the results of extensive research on fruits, ornamentals, vegetables and cotton (in NSW) in which the effectiveness of petroleum-derived spray oils (PDSOs) on insect and mite pests has been u

Key factors in managing transgenic Bt cottons for the future are to have an effective resistance management strategy. An essential component of any such strategy is to establish a resistance monitoring program.

It has been 9 years now since the introduction of the Summer Crop Resistance Management Strategy in 1983/84 season.

Outbreaks of native budworm, Helicoverpa punctigera, often arise after egg laying by emigrant moths from distant populations.

The pattern of flight activity within or between habitats or crops is dependent upon the distribution of those habitats/crops in both space and time.

The purpose of our four-year study on the Darling Downs was 1) to investigate the population dynamics of heliothis and to quantify the significance of the major controlling influences (parasites, predators, pathogens,

It is already well established that sprays containing the ultra-safe pesticide azadirachtin are very effective in reducing egg-laying Heliothis spp. in cotton in the field
