Development of a Microbial-Based Integrated Pest Management Program for Helicoverpa spp. (Lepidoptera: Noctuidae) and Beneficial Insects on Conventional Cotton Crops in Australia

open access: yesInsects, 2015
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.

Functional Characterization of two Carboxylesterase Genes Involved in Pyrethroid Detoxification in Helicoverpa armigera.

open access: yesJournal of Agricultural and Food Chemistry, 2020
Insect carboxylesterases are major enzymes involved in metabolism of xenobiotics including insecticides. Two carboxylesterase genes, CarE001A and CarE001H, were cloned from the destructive agricultural pest Helicoverpa armigera.

Movement Ecology of Pest Helicoverpa: Implications for Ongoing Spread.

open access: yesAnnual Review of Entomology, 2019
The recent introduction and spread of Helicoverpa armigera throughout South America highlight the invasiveness and adaptability of moths in the Helicoverpa genus. Long-range movement in three key members, H. armigera, H. zea, and H. punctigera, occurs by

Hybridization and introgression between Helicoverpa armigera and H. zea: an adaptational bridge

open access: yesBMC Evolutionary Biology, 2020
Invasion of organisms into new ecosystems is increasingly common, due to the global trade in commodities. One of the most complex post-invasion scenarios occurs when an invasive species is related to a native pest, and even more so when they can ...
