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 ...

Effects of photoperiod and temperature on diapause induction of Lobesia botrana

Guoshu xuebao
【Objective】Many insects utilize diapause to cope with various environmental stresses, and photoperiod and temperature play significant roles in diapause induction for numerous insect species.

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

A Photoreceptor Contributes to the Natural Variation of Diapause Induction in Daphnia magna [PDF]

, 2016
Diapause is an adaptation that allows organisms to survive harsh environmental conditions. In species occurring over broad habitat ranges, both the timing and the intensity of diapause induction can vary across populations, revealing patterns of local ...

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.

Rearing Istocheta aldrichi (Diptera: Tachinidae) From Field‐Collected Japanese Beetles (Popillia japonica): 2. Methods to Improve Overwintering, Adult Emergence and Longevity

Entomologia Experimentalis et Applicata, EarlyView.
Successful rearing of Istocheta aldrichi, a tachinid parasitoid of invasive Japanese beetle, depended on conditions before, during, and after overwintering. Longer cold exposure increased adult emergence and accelerated post‐diapause development. Early transfer of puparia to cool conditions improved survival, while spring temperature manipulation ...

Eusocial bee species are exposed to different toxic element profiles despite foraging within the same landscape

Ecological Entomology, EarlyView.
Bombus terrestris and Apis mellifera colonies sharing the same landscape (<50 m from each other) collected pollen with significantly different heavy metal concentrations. B. terrestris‐collected pollen contained 2–7× higher concentrations of arsenic, chromium, cobalt, lead and tin than A. mellifera‐collected pollen.

Local habitat, not landscape diversity, drives richness and reproduction of cavity‐nesting bees and wasps in agricultural landscapes

Insect Conservation and Diversity, EarlyView.
Local habitat type and hedgerow cover strongly shape bee and wasp richness, but only weakly their reproductive output, outweighing the landscape diversity effects at the 1‐km2 scale. Forests host more wasp but fewer bee species, whereas orchards support high richness of both; bee reproduction patterns are driven by one dominant species, while wasp ...

Trade‐offs in thermal response: Schizotetranychus brevisetosus winter eggs outperform summer eggs at low temperatures

Physiological Entomology, EarlyView.
We investigated maternal effects in Schizotetranychus brevisetosus (Tetranychidae), where females oviposit summer and winter eggs in response to photoperiod on evergreen hosts. Developmental rates of immature individuals increased linearly from 15°C to 35°C, but winter and summer eggs developed faster at low and high temperatures, respectively ...
