Full‐length coding sequence analysis of the voltage‐gated sodium channel and acetylcholinesterase genes reveals target‐site mutations and acetylcholinesterase gene duplication in housefly (Musca domestica) populations in Japanese livestock barns

open access: yesMedical and Veterinary Entomology, EarlyView.
We simultaneously analysed insecticide resistance mutations in VGSC and AChE using NGS and hybridization probe capture in houseflies collected from livestock facilities for the first time. Resistance mutations in both VGSC and AChE were detected in most wild populations, suggesting widespread distribution of resistance genes.

Population structure and gene flow in the global pest, Helicoverpa armigera [PDF]

open access: yes, 2016
Helicoverpa armigerais a major agricultural pest that is distributed across Europe, Asia, Africa and Australasia. This species is hypothesized to have spread to the Americas 1.5million years ago, founding a population that is at present, a distinct ...

Assessment of beneficial role of an insectivorous bird, jungle babbler (Turdoides striatus) predation, on Helicoverpa armigera infesting pigeon pea (Cajanus cajan) crop

open access: yesActa Agronómica, 2010
Jungle babbler (Turdoides striatus), a widely spread sub-tropical insectivorous passerine is considered beneficial to agro-ecosystem, as they devour voraciously on insect matter especially Helicoverpa armigera, the gram pod borer, a notorious pest ...

Aboveground and Belowground Insect Herbivory Changes Maize‐Wireworm Interactions via Root Volatile Cues

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT The rhizosphere harbours critical plant‐herbivore interactions often mediated by small lipophilic molecules (SLMs). Despite the agricultural importance of many soil‐dwelling insects, surprisingly little is known about chemically mediated belowground crop‐pest interactions. Root and shoot herbivores can influence these interactions by modifying

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

open access: yesBMC Evolutionary Biology, 2020
Background 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 ...

Treatment of cotton with plant growth‐promoting rhizobacteria consortium alters host location and oviposition of Spodoptera exigua

open access: yesPest Management Science, Volume 82, Issue 7, Page 7123-7136, July 2026.
Two plant‐growth promoting rhizobacteria (PGPR) consortia (AU8 and TX1) induced a deterrence of host plant location and oviposition behavior of Spodoptera exigua females in both susceptible and resistant cotton plants. Most of the volatile organic compounds (VOCs) increased in PGPR‐treated plants compared to untreated plants. # indicates treatments not

PATHOGENICITY OF HELICOVERPA ARMIGERA NUCLEOPOLYHEDRO VIRUS (HEARNPV) AND LECANICILLIUM SP. AGAINST HELICOVERPA ARMIGERA

open access: yesJournal of Biopesticides, 2018
ABSTRACT Helicoverpa armigera (Hubner) is an important pest of corn crops. Lecanicillium sp. and Helicoverpa armigera Nucleopolyhedro virus (HearNPV) are biological control agents that are safe for the environment. This study observed pathogenicity of HearNPV and Lecanicillium sp. against eggs and larvae H. armigera.
