Bumblebee venom serine protease increases fungal insecticidal virulence by inducing insect melanization. [PDF]
PLoS ONE, 2013 Insect-killing (entomopathogenic) fungi have high potential for controlling agriculturally harmful pests. However, their pathogenicity is slow, and this is one reason for their poor acceptance as a fungal insecticide.

The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks
Agricultural and Forest Entomology, EarlyView.Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive

Insect Molecular Biology, EarlyView.Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Egyptian Journal of Biological Pest Control, 2019 A local isolate of the fungus Beauveria bassiana was tested against the beet armyworm Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) larvae reared on artificial diet. Seven successive increased conidiospore concentrations (2 × 101, 2 × 102, 2 × 103,

Advanced Sustainable Systems, Volume 10, Issue 9, September 2026.This study advances sustainable pest management by characterizing novel insect‐specific pheromone compounds with a linear release profile. Release rate constants are derived from accelerated high‐temperature tests, enabling broadly applicable comparisons of pheromone‐polymer compounds.

New Antifeedant Grayanane Diterpenoids from the Flowers of Pieris formosa
Molecules, 2017 Three new grayanane diterpenoids, pierisoids C‒E (1–3), as well as 10 known ones (4–13), were evaluated from the flowers of Pieris formosa, which is used as an insecticide in rural areas of China.

Insects, 2022 MicroRNAs (miRNAs) drive the post-transcriptional repression of target mRNAs and play important roles in a variety of biological processes. miR-2766-3p is conserved and abundant in Lepidopteran species and may be involved in a variety of biological ...

Ecology and Evolution, Volume 16, Issue 9, September 2026.Introduced plants represent unique opportunities to understand how diverse phenotypic traits vary across broad geographic scales. However, clear generalizable principles about genetically based variation in key functional plant traits across geographic clines remain elusive. To address this knowledge gap, we assessed how heritable variation in knotweed

Synchronized oviposition triggered by migratory flight intensifies larval outbreaks of beet webworm. [PDF]
PLoS ONE, 2012 Identifying the reproductive consequences of insect migration is critical to understanding its ecological and evolutionary significance. However, many empirical studies are seemingly contradictory, making recognition of unifying themes elusive and ...
