Wolf spiders are abundant and voracious predators at the soil-plant interface in cotton crops. Among other prey, they attack late-instar larvae of the cotton bollworm Helicoverpa spp., an economically important pest.

- - The cotton bollworm, Helicoverpa armigera, has developed resistance to various insecticides, particularly pyrethroids, making it a significant global pest following its spread to South America and North America.
- - A key resistance mechanism involves a chimeric cytochrome P450 gene known as CYP337B3, which has multiple alleles and is prevalent globally, including in South America.
- - The presence of similar alleles in Brazil and Asia suggests that the resistance could have originated from Asian populations, potentially explaining H. armigera's introduction into the Americas.
The Management of Insect Pests in Australian Cotton: An Evolving Story.
Annu Rev Entomol
January 2018
The Australian cotton industry progressively embraced integrated pest management (IPM) to alleviate escalating insecticide resistance issues. A systems IPM approach was used with core principles that were built around pest ecology/biology and insecticide resistance management; together, these were integrated into a flexible, year-round approach that facilitated easy incorporation of new science, strategies, and pests. The approach emphasized both strategic and tactical elements to reduce pest abundance and rationalize decisions about pest control, with insecticides as a last resort.
