Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives

Insect Science, EarlyView.
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

Pharmacological analysis of the feeding response of codling moth (Cydia pomonella; Lepidoptera: Tortricidae) neonates to bitter compounds

European Journal of Entomology, 2017
Feeding in codling moth neonate caterpillars was inhibited by 0.67 mM and 2.24 mM concentrations of denatonium benzoate. This inhibitory effect was abolished by phospholipase C inhibitor, U-73122 and the phosphodiesterase inhibitor, Rolipram. Quinine and

Male genital variation in a moth Pammene luedersiana (Lepidoptera: Tortricidae)

European Journal of Entomology, 2007
Insect genital characters are extensively used in species level taxonomy, and their value in species delimitation is great. Based on the lock-and-key hypothesis and that genital differences function as a mechanical isolation system between species, the ...

Comparative Toxicity of Bordeaux Mixture by Ingestion and Cuticular Contact Under Climate Change Conditions on Trichogramma cordubensis

Entomologia Experimentalis et Applicata, EarlyView.
In the face of environmental contamination to copper, mainly resulting from frequent copper‐based fungicide applications, it is crucial to understand the side effects of these pesticides on non‐target organisms to improve pest management. Trichogramma cordubensis, used as a biological control agent against grape berry moths in vineyards, shows strongly

Molecular Phylogeny and Strain Genotyping of the Bacterial Endosymbiont Wolbachia Associated With Tuta absoluta Populations

Entomologia Experimentalis et Applicata, EarlyView.
This study was designed to understand the association between reproductive endosymbiotic bacteria and wild and laboratory‐reared Tuta absoluta populations. The majority of T. absoluta populations showed Wolbachia presence at varying levels of infection, whereas Arsenophonus, Cardinium, and Spiroplasma were not detected. Wolbachia‐positive T.

Phenological shifts and increases in voltinism within a moth community over a century of anthropogenic change

Ecology, Volume 107, Issue 3, March 2026.
Abstract In temperate ecosystems, warming temperatures can advance spring phenology, extend autumn phenology, disrupt dormancy regulation, result in phenological mismatch across taxa, and even lead to increases in the number of generations per year (i.e., increases in voltinism).

Climate Change Has Already Reshaped North American Forest Pest Dynamics: Insights From Multidecadal Process‐Based Modelling

Global Change Biology Communications, Volume 1, Issue 1, March 2026.
Climate change has rapidly expanded and shifted suitable climate conditions for eight major forest pests across North America, especially toward northern and higher elevation areas. Host exposure and overlap among pests are increasing, raising ecological and economic risks, and signaling accelerating future impacts under continued warming.
