Functional variation in butterfly egg pore traits: The potential role of climate

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Immobile eggs of terrestrial animals are exposed to variable environmental conditions. Insect egg pores, critical for gas exchange (aeropyles) and fertilisation (micropyles), are ecologically important yet understudied.

Prepupal diapause reduces adult lifespan in the solitary alfalfa leafcutter bee

Scientific Reports
Diapause is an adaptation that allows many insects to survive adverse environmental conditions. While diapause-associated trade-offs with reproduction are well-documented, its potential impact on lifespan and long-term adult physiology remains poorly ...

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 ...

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.

A horizontally transferred bacterial gene for pantothenic acid biosynthesis regulates diapause and reproduction in the spider mite Amphitetranychus viennensis

Insect Science, EarlyView.
A bacterial‐derived AvPBL gene encoding a pantothenate‐β‐alanine ligase was identified in Amphitetranychus viennensis. RNAi silencing of AvPBL reduced pantothenic acid production, impairing reproduction and diapause induction, while pantothenic acid supplementation rescued these phenotypes.

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

Rearing Istocheta aldrichi (Diptera: Tachinidae) From Field‐Collected Japanese Beetles (Popillia japonica): 1. Methods to Improve Insect Collection and Parasitoid Pupariation

Entomologia Experimentalis et Applicata, EarlyView.
We describe methods for collecting and rearing the tachinid parasitoid Istocheta aldrichi from parasitized Japanese beetle adults. Hosts can be collected by hand and reared in the laboratory, or by using modified trap containers with added plant material and substrate to provide suitable conditions for I.

Photoperiodic diapause in a subtropical population of Aedes albopictus in Guangzhou, China: optimized field-laboratory-based study and statistical models for comprehensive characterization

Infectious Diseases of Poverty, 2018
Background Aedes albopictus is among the 100 most invasive species worldwide and poses a major risk to public health. Photoperiodic diapause provides a crucial ecological basis for the adaptation of this species to adverse environments. Ae. albopictus is
