Susceptibility Profiles of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) to Deltamethrin Reveal a Contrast between the Northern and the Southern Benin

open access: yesInternational Journal of Environmental Research and Public Health, 2019
Helicoverpa armigera is an indigenous species in Africa and has been reported in the destruction of several crops in Benin. Management of H. armigera pest is mainly focused on the use of synthetic pyrethroids, which may contribute to resistance selection.

LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus

open access: yesInsect Science, EarlyView.
The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.

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.

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.

Drought and Herbivory Drive Physiological and Phytohormonal Changes in Soybean (Glycine max Merril): Insights From a Meta‐Analysis

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT With climate change, abiotic and biotic stresses such as drought and herbivory are predicted to further diminish agricultural productivity. Soybean (Glycine max [L.] Merrill), a crop of global economic importance, is vulnerable to both. However, the interactive effects of drought and herbivory on soybeans haven't been explored, especially ...
