Entomopathogenic fungi, when used as a microbial control agent against cotton pests, such as Helicoverpa spp., may have the potential to establish and spread in the environment and to have an impact on both pests and beneficial insects. Information on the effect of entomopathogenic fungi on pests and beneficial insects is crucial for a product to be registered as a biopesticide. The effect of t...

Helicoverpa spp. and mirids, Creontiades spp., have been difficult to control biologically in cotton due to their unpredictable temporal abundance combined with a cropping environment often made hostile by frequent usage of broad spectrum insecticides. To address this problem, a range of new generation insecticides registered for use in cotton were tested for compatibility with the assassin bug...

Mounting levels of insecticide resistance within Australian Helicoverpa spp. populations have resulted in the adoption of non-chemical IPM control practices such as trap cropping with chickpea, Cicer arietinum (L.). However, a new leaf blight disease affecting chickpea in Australia has the potential to limit its use as a trap crop. Therefore this paper evaluates the potential of a variety of wi...

BACKGROUND Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is one of the major pests of maize and is in the same feeding guild as the noctuid pests Helicoverpa zea (Boddie) and Helicoverpa armigera (Hübner), recently reported in South and North America. The intraguild interactions of these species were assessed in laboratory and field conditions by determining the survival of larvae...

We report here the genome sequences of two alphabaculoviruses of Helicoverpa spp. from Australia: AC53, used in the biopesticides ViVUS and ViVUS Max, and H25EA1, used in in vitro production studies.

Insect pests may have a severe impact on cotton production in Australia. Key pests are Helicoverpa spp which are well adapted to exploit cropping systems and often evolve resistance to pesticides. Until recently adoption of IPM has been restricted by a lack of nondisruptive tools. IPM must be founded on a thorough understanding of the ecology of pest and beneficial species, their interaction wi...

Abstract The objective of this work was to identify, by molecular analysis, the species genus Helicoverpa in corn, soybean, and lucerne Bt non-Bt crops, central Argentina. A total 1,343 carterpillars were analyzed PCR-RFLP. zea only detected on most corn hybrids. H. gelotopoeon predominated soybean lucerne, larvae occurred low proportion. did not show spp. infestations. exotic armigera found, t...

The first-generation transgenic cotton (Gossypium hirsutum L.), Bollgard, which contains a single toxin protein gene cry1Ac from Bacillus thuringiensis var. kurstaki Berliner, was approved by the National Biosafety Committee (NBC) for commercial growing in Pakistan in 2011 and the yield enhancement is promising, with an increase in cotton bales up to 150 millionthe record productivity of the co...

BACKGROUND Evolution of resistance by target pests is the main threat to the long-term efficacy of crops expressing Bacillus thuringiensis (Bt) insecticidal proteins. Cry2 proteins play a pivotal role in current Bt spray formulations and transgenic crops and they complement Cry1A proteins because of their different mode of action. Their presence is critical in the control of those lepidopteran ...
