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

open access: yesInsect 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 ...

Oviposition preference maximizes larval survival in the grass-feeding butterfly Melanitis leda (Lepidoptera: Nymphalidae)

open access: yesEuropean Journal of Entomology, 2020
Phytophagous insects may be expected to prefer host-plant species on which their larvae perform best, but this has rarely been explored in grass-feeding butterflies.

Egg Adhesion of the Codling Moth Cydia pomonella L. (Lepidoptera, Tortricidae) to Synthetic Substrates

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Previous studies on Cydia pomonella eggs have demonstrated reliable egg adhesion to the leaves and fruits of various apple cultivars. In contrast to biological substrates, this study is focused on standardised synthetic substrates to measure egg pull‐off forces and determine adhesive strength, allowing for an unbiased comparison with other ...

Generalization for both diurnal and nocturnal pollination in the mass‐flowering desert geophyte Nerine laticoma (Amaryllidaceae)

open access: yesPlant Biology, EarlyView.
Both diurnal and nocturnal pollinators are important in the desert plant Nerine laticoma. Abstract The evolutionary limits to generalization in plant pollination systems are often determined by trade‐offs in which adaptations to one set of flower visitors reduces the effectiveness of another set of visitors.

Dragon Fruit (Hylocereus undatus) Pollination in New Zealand: A Preliminary Report on Flower Visitors, Natural Pollen Deposition, and Artificial Pollination

open access: yesNew Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
Dragon fruit (pitaya; Hylocereus undatus) is a promising, new high‐value crop in New Zealand. The large nocturnal flowers open for one night and close early in the morning the following day over a 3‐ to 6‐month long flowering period. In dragon fruit's native range, hawkmoths and bats are key nocturnal pollinators, and honey bees visit flowers during ...

A Novel Sampling Protocol for Fruit‐Feeding Butterflies in Grasslands and Open Habitats

open access: yesAustral Ecology, Volume 51, Issue 1, January 2026.
This study proposed a novel sampling protocol for fruit‐feeding butterflies in grasslands and open areas in the subtropical region. The new method involves the use of Van Someren‐Rydon bait traps placed on specific supports closer to the ground, aiming to capture the true diversity of butterflies in these habitats.
