Austral Entomology, Volume 65, Issue 4, November 2026.ABSTRACT Spodoptera litura (Fabricius) is a highly polyphagous lepidopteran pest; however, little is known about its seasonal population dynamics or larval host plant use in northern Australia. Improved understanding of the ecology of S. litura is increasingly important given the anticipated expansion of Bacillus thuringiensis (Bt) cotton production in

Soybean induced resistance to Spodoptera eridania herbivory
Pest Management Science, Volume 82, Issue 10, Page 9931-9943, October 2026.SOD, CAT, APX, PPO, KTI, and MDA levels were higher in the resistant soybean. S. eridania herbivory increased H2O2 and MDA, but decreased SOD and PPO levels. S. eridania herbivory increased KTI activity only in the resistant variety. Isoquercitrin and daidzin were exclusive to resistant and susceptible soybeans.

Insect Molecular Biology, Volume 35, Issue 5, Page 594-612, October 2026.Genome‐wide systematic annotation identified 81 odorant receptors (ORs) and 49 odorant‐binding proteins (OBPs) in the tobacco budworm, Chloridea virescens. Phylogenetic analyses revealed chemosensory gene diversification in Heliothinae and extensive lineage‐specific duplications in C.
