Characterisation of Neonicotinoid Resistance in the Cotton Aphid, Aphis Gossypii from Australian Cotton

Book Description
The cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae), is a highly polyphagous pest that inflicts serious damage to a broad range of agricultural, horticultural and greenhouse crops. In Australia, A. gossypii is a significant pest of cotton and is difficult to control with insecticides because of its high propensity to develop resistance. Neonicotinoids are among the most effective insecticides used to control A. gossypii but the most recent detection of resistance threatens their longevity. Consequently, I aimed to restore neonicotinoid efficacy against A. gossypii through elucidation of underlying resistance mechanism(s). Bioassay was used to measure thiamethoxam (neonicotinoid) response in three field strains collected from commercial cotton. A second trial investigated the use of phorate (an organophosphate) as an alternative pre-germination treatment to thiamethoxam. PCR-Sequencing was employed to identify if mutation R81T known to confer resistance to neonicotinoid compounds was present in Australian A. gossypii. High-throughput sequencing of the A. gossypii transcriptome found differences in gene expression associated wit hthiamethoxam resistance. Two transcripts involved in the detoxification of xenobiotics (putatively annotated as cytochrome p450 gene 6K1-like) were found differentially expressed between resistant and suceptible strains. Transcript expression was further validated by qRT-PCR and showed a similar tendency in upregulation of expression. As such I identified this gene as the strongest candidate for thiamethoxam resistant A. gossypii. This study has generated a comprehensive transcriptome resource for A. gossypii that has characterised the expression of numerous important transcripts encoding proteins involved in insecticide resistance. Consequently, my study will contribute to future research relating to molecular characterization of insecticide resistance mechanisms in A. gossypii and other insect pests.

Book Description
This book presents a global overview of the background to, and the current state of, crop protection and pest management in cotton crops. Cotton is one of the most economically important crops in the world and has been grown for centuries but maintaining high yields of good quality requires sophisticated approaches to pest management. The introduction and use of pesticides over the decades significantly increased cotton yields but lead to many adverse environmental impacts. Over time, new and alternative insecticides were developed but overuse has enabled pests to develop significant resistance. The development of genetically modified cotton varieties with toxins derived from Bacillus thuringiensis enabled much improved control of lepidopteran larvae, including bollworms, but as the toxins had no effect on sucking pests, farmers had no choice but to continue using insecticides. Also, some of the new cotton varieties developed in recent times have not adapted to different climatic conditions and the quality of cotton fibre declined as a result. This book shows the need for more research to select cotton varieties with high quality fibres suitable for different cotton growing areas and to develop integrated pest management strategies to minimise the use of pesticides. It also demonstrates the need for an inter-disciplinary approach bringing together plant breeders, entomologists, plant pathologists, agronomists and agricultural engineers to achieve high yields of high quality cotton.
