Overwintering Strategies and Post-Diapause Female Reproduction Fitness in the Willow Leaf Beetle Plagiodera versicolora (Coleoptera: Chrysomelidae)

Insects
Diapause, a survival strategy utilized by many insects under severe environmental conditions, can generate costs that potentially affect post-diapause development and reproduction.

HvarAKR1B1‐mediated tolerance in Hippodamia variegata: Deciphering the metabolic adaptation and fitness costs under prolonged starvation

Pest Management Science, Volume 82, Issue 8, Page 7903-7914, August 2026.
Starvation stress significantly affected the growth and development of Hippodamia variegata. Combined transcriptome and metabolome analysis and RNA interference verification revealed that HvarAKR1B1 may be involved in the response of Hippodamia variegata to starvation stress.

Lipid Metabolism in Diapause

Organisms living in temperate and polar environments encounter seasonal fluctuations that entail changes in temperature, resource availability, and biotic interactions. Thus, adaptations for synchronizing the life cycle with essential resources and persisting through unfavorable conditions are critical.

Development and Reproduction of Nesidiocoris tenuis Reuter (Heteroptera: Miridae): The Effect of Temperature, Origin and Food

Entomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 842-850, August 2026.
Nymphal development took longer at 25°C than 30°C, and the Greek N. tenuis population developed more slowly than the commercial population. Nymphs clearly preferred E. kuehniella eggs over Artemia sp. cysts when both were offered equally. Egg production increased at 30°C, while female longevity declined.

Effect of Photoperiod and Temperature on the Induction and Termination of Diapause in Lygus pratensis (Hemiptera, Miridae)

Agronomy
Lygus pratensis is an important pest of cotton in the Xinjiang Uyghur Autonomous Region, Chana. Diapause plays a key role in seasonal survival, population dynamics, and spring population establishment of this species; therefore, understanding the ...

The Parasitoid Wasp Glyptapanteles porthetriae Induces a Photoperiod‐Dependent Diapause‐Like State in Its Potential Overwintering Host Lasiocampa quercus

Entomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 896-907, August 2026.
We evaluated Lasiocampa quercus as an overwintering host for the koinobiont larval endoparasitoid Glyptapanteles porthetriae by exposing parasitized larvae to different environmental conditions and comparing parasitoid development with that in the primary host Lymantria dispar.

Genome-wide analysis reveals transcriptional and translational changes during diapause of the Asian corn borer (Ostrinia furnacalis)

BMC Biology
Background Diapause, a pivotal phase in the insect life cycle, enables survival during harsh environmental conditions. Unraveling the gene expression profiles of the diapause process helps uncover the molecular mechanisms that underlying diapause, which ...

Performance of Leptopilina japonica Novković and Kimura (Hymenoptera: Figitidae) Under Fluctuating Temperature and Humidity

Entomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 876-886, August 2026.
Temperature is an important factor to determine the activity of insects. We tested the performance of the non‐native larval parasitoid Leptopilina japonica (Hymenoptera: Figitidae) under realistic climatic conditions to improve understanding about its ongoing spread and seasonal abundance.

Diapause survival requires a temperature-sensitive preparatory period

Current Research in Insect Science
Diapause is a form of internally-controlled dormancy that allows insects to avoid stressful conditions and periods of low food availability. Eastern spruce budworm (Choristoneura fumiferana Clemens), like many cold-adapted insects, enter diapause well in
