Long‐term changes and host plant differences in the incidence of parasitoids attacking Helicoverpa spp. (Lepidoptera: Noctuidae) in agricultural landscapes in eastern Australia
Greater parasitoid frequencies were often found in eggs, larvae and pupae of Helicoverpa in crops surveyed after the advent of Bt cotton, compared with earlier years.
Do the plant host origins of Helicoverpa (Lepidoptera: Noctuidae) moth populations reflect the agricultural landscapes within which they are caught?
It is suggested that C4 host plants are likely to be very important in offsetting the development of Bt resistance in these insects and such influences may operate across multiple regions within a single growing season.
Invasions of green mirid (Creontiades dilutus) (Stål) (Hemiptera: Miridae) into cotton – perceptions of Australian crop consultants
Assessment of records on mirid infestations spanning the 1976/77 through 2015/16 cotton seasons found agreement that the earliest seasonal mirid invasions were associated with squaring (flower bud forming) cotton, and were influenced by nearby vegetation.
Pigeon pea refuge crops are likely to provide patchy delivery of Helicoverpa (Lepidoptera: Noctuidae) within Bt cotton production regions in eastern Australia
The results of the model suggested that delivery of moths from refuges to Bt cotton crops throughout the St George landscape would be patchy, with some areas thus more likely to be exposed to the threat of Bt resistance development than others.
Baseline susceptibility and cross‐resistance in Aphis gossypii Glover (Aphididae: Hemiptera) to phorate and sulfoxaflor
If phorate is used as a side dressing in Australian cotton for insect control, neither pirimicarb, or any other chemical associated with insensitive acetylcholinesterase type one resistance, should be used as the first foliar spray for any subsequent aphid control.
Can sustainable cotton production systems be developed for tropical northern Australia?
Limits thought to be associated with cotton production in northern Australia can be overcome by developing a deep understanding of biotic and environmental constraints, then tailoring and validating production practices, according to key lessons from the Cotton CRC research effort.
Broad-scale suppression of cotton bollworm, Helicoverpa armigera (Lepidoptera: Noctuidae), associated with Bt cotton crops in Northern New South Wales, Australia.
Great toxicity of the two gene product, introduction of no cap on Bt cotton proportion, and an increase in natural enemy abundance are suggested as the most likely mechanisms responsible for the suppression observed.
Quantification of the Pirimicarb Resistance Allele Frequency in Pooled Cotton Aphid (Aphis gossypii Glover) Samples by TaqMan SNP Genotyping Assay
A new method to quantify a resistance allele frequency (RAF) from pooled insects via TaqMan assay is demonstrated by using raw fluorescence data to calculate the transformed fluorescence ratio k’ at the inflexion point based on a four parameter sigmoid curve.
Can resistance management strategies recover insecticide susceptibility in pests?: a case study with cotton aphid Aphis gossypii (Aphididae: Hemiptera) in Australian cotton
The integrated strategy has now almost completely recovered susceptibility to IPM friendly pirimicarb and resistance to neonicotinoid insecticides has declined dramatically.
Efficacy of two thiamethoxam pre‐germination seed treatments and a phorate side‐dressing against neonicotinoid‐ and pirimicarb‐resistant cotton aphid, Aphis gossypii (Hemiptera: Aphididae)
The use of phorate as an alternative pre‐germination treatment to thiamethoxam for aphid control must be managed and the first foliar spray applied to cotton treated with phorate at planting should not be pirimicarb or any other insecticide affected by insensitive cholinesterase (ACE1) type resistance.
