Effects of β-sitosterol on growth, development and midgut enzymes of Helicoverpa armigera Hübner

open access: yesArchives of Biological Sciences, 2020
Helicoverpa armigera is a global agricultural pest of serious concern. Continued use of chemical insecticides as control measures has raised grave health and environment concerns, necessitating a search for botanicals as safe alternatives.

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Taxonomic and functional diversity of noctuoid moths in a Mediterranean coastal area: implications for dune conservation in a long‐term ecological research eLTER site

open access: yesInsect Science, EarlyView.
This study investigates the taxonomic and functional diversity of noctuoid moths in a protected coastal dune system in Central Italy, revealing strong ecological associations between moth assemblages and dune zonation. Differences in species composition and trait attributes, along with the presence of habitat‐exclusive species, highlight the role of ...

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.

Potential climate warming effects on the distribution of an invasive alien pest species

open access: yesEcological Entomology, Volume 51, Issue 1, Page 113-125, February 2026.
Drosophila suzukii (SWD) has low resistance to heat waves. The incidence of SWD differed between Illyric‐ and Pannonian climate zone. Desert days (frequency) only increased in the Pannonian zone. Abstract Climate warming can be a powerful driver for the establishment and further spread of alien species by lowering the abiotic resistance of native ...

Air pollution and its multifaceted effects on insect pollinators: A review

open access: yesEcological Entomology, Volume 51, Issue 1, Page 1-17, February 2026.
Air pollution disrupts plant‐pollinator interactions by impairing floral signal transmission, altering foraging behaviour, and reducing pollinator fitness, flight efficiency, reproduction and survival, posing serious threats to ecological stability.

Peptides Derived From Reactive Center Loops Inhibit Digestive Trypsin‐Like Enzymes in Lepidopteran Pests

open access: yesArchives of Insect Biochemistry and Physiology, Volume 121, Issue 1, January 2026.
Soybean yield is often reduced by pest attacks. Among these, Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae) stands out as one of the most important defoliating pests of soybean. Therefore, the development of new bioinsecticides targeting Lepidopteran pests is an urgent need.
