Changes in Energy Metabolism Trigger Pupal Diapause Transition of Bactrocera minax After 20-Hydroxyecdysone Application

Frontiers in Physiology, 2019
Correct timing of diapause entry and exit is critical for a species' survival. While many aspects of insect diapause are well-studied, the mechanisms underlying diapause termination remain largely unknown.

Alternative seed trait strategies are linked to a trade‐off between spatial and temporal dispersal

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Seed dispersal allows plants to seek favourable conditions or spread the risk of unfavourable conditions through space and time. While theory predicts a trade‐off between spatial and temporal dispersal, empirical tests have been stymied by the difficulty of measuring ...

A model for the overwintering process of European grapevine moth Lobesia botrana (Denis & Schiffermüller) (Lepidoptera, Tortricidae) populations

Journal of Entomological and Acarological Research, 2012
The paper deals with the development, parametrization and validation of a phenology model of the overwintering process of European grapevine moth Lobesia botrana (Denis & Schiffermüller) populations in northern latitudes.

Cold storage effects on immature calliphoridae: Survival limits and forensic consequences for PMI estimation

Journal of Forensic Sciences, EarlyView.
Abstract This study investigated the effects of continuous refrigeration (4°C ± 2°C and 50% ± 5% RH) on the development and survival of immature stages (eggs, first, second, and third instar larvae, and pupae) of four forensically important blowfly species (Chrysomya megacephala, Chrysomya putoria, Hemilucilia segmentaria, and Lucilia cuprina) compared

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

Insect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Bigger isn't always better: Challenging assumptions about the associations between diapause, body weight, and overwintering survival

Ecology and Evolution
During the winter, animals face limited food availability. Many animals enter dormancy to reduce their winter energy expenditure. Most insects spend the winter in diapause, a state of programmed dormancy.

A multi‐year dormancy strategy in a cabbage beetle population in southeastern China

Ecology and Evolution, 2022
The life cycle of the cabbage beetle Colaphellus bowringi in southeastern China is complex due to four options for adult development: summer diapause, winter diapause, prolonged diapsuse, and nondiapause.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

Insect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

High-throughput profiling of diapause regulated genes from Trichogramma dendrolimi (Hymenoptera: Trichogrammatidae)

BMC Genomics, 2020
Background The parasitoid wasp, Trichogramma dendrolimi, can enter diapause at the prepupal stage. Thus, diapause is an efficient preservation method during the mass production of T. dendrolimi.

The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks

Agricultural and Forest Entomology, EarlyView.
Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive
