Wing morph- and age-related differences in fertilization success of adult males of a flightless bug, Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

open access: yesEuropean Journal of Entomology, 2008
The aim of the present study was to test the hypothesis that short-winged (brachypterous) and long-winged (macropterous) adult males of a flightless bug Pyrrhocoris apterus differ in fertilization success.

Photoperiod‐Regulated Thermal Tolerance of the Non‐Diapausing Insect Ceratitis capitata (Diptera: Tephritidae)

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Developmental photoperiodic exposure (photoacclimation) from egg to adult emergence alters thermal tolerance in Ceratitis capitata. Flies reared under contrasting photoperiods (0:24, 8:16, 14:10, and 24:0 L:D) showed significant shifts in both CTmin and CTmax, whereas adult‐only photoacclimation affected CTmax but not CTmin.

Juvenile hormone‐mediated accelerated post‐flight recovery of ovarian development in Loxostege sticticalis (Lepidoptera: Crambidae)

open access: yesNew Plant Protection, Volume 3, Issue 1, March 2026.
Flight in female beet webworms (Loxostege sticticalis) promotes an increase in feeding, thereby enhancing abdominal energy reserves. Following flight, the flight muscles undergo accelerated histolysis, and the energy substances undergoing histolysis are redirected to the ovaries. These two processes collectively promote ovarian development.
