Gossypol detoxification in the rumen and Helicoverpa armigera larvae: A review
Animal Nutrition, 2021 Gossypol, a phenolic compound found in the cotton plant, is widely distributed in cottonseed by-products. Although ruminant animals are believed to be more tolerant of gossypol toxicity than monogastric animals due to rumen microbial fermentation, the actual mechanisms of detoxification remain unclear.

Parental effects of Bt toxin and vitamin A on Helicoverpa armigera
PLOS ONE, 2022 The increase in the area cultivated with vitamin-enriched transgenic crops producing Bt toxin raises the question of whether the addition of vitamins will in any way mitigates the effect of the toxin on the phytophagous insects that feed on those crops.

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

Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities
Integrative Zoology, EarlyView.Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

Matrine–Tea Saponin Synergism Involves Suppressed Detoxification and Digestion in a Leaf Beetle
Integrative Zoology, EarlyView.Tea saponin and matrine showed synergistic toxicity against Plagiodera versicolora. Combined exposure suppressed digestion‐ and detoxification‐related processes, while silencing the trypsin gene Pver105950 and chitinase gene Pver001190 increased larval susceptibility to tea saponin and matrine, respectively.
