Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

open access: yesInsect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

open access: yesInsect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

Characterization of the dynamic microbiome evolution across thrips species

open access: yesInsect Science, EarlyView.
Comprehensive survey of the microbiome in thrips. The dominant bacterial genera found in thrips include intracellular ones, such as Wolbachia and Spiroplasma, and extracellular ones, including Serratia, Pantoea, and Acinetobacter. We isolated and sequenced high‐quality genomes of two dominant symbionts, Pantoea dispersa and Serratia marcescens.

Climatic conditions, landscape, and habitat quality drive patch occupancy and larval density of a threatened mire butterfly

open access: yesInsect Science, EarlyView.
The Moorland Clouded Yellow (Colias palaeno) benefited from cattle grazing in three different ways by (i) fostering the nectar supply; (ii) enhancing rejuvenation of the host plant (Vaccinium uliginosum); and (iii) improving microclimatic conditions for successful development of the immature stages.

Mothbox and Mothbot: Automated light trap and data processing system for scalable insect monitoring

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Insects represent the most diverse group of organisms on Earth and comprise the majority of known species; yet they are seldom accounted for in large‐scale biodiversity monitoring systems and conservation planning. We have developed the Mothbox—an open source automated light trap that makes insect monitoring accessible to non‐specialists and ...

Degree of insecticide exposure and access to nectar impact survival of Trissolcus japonicus, a hymenopteran parasitoid, in flowering border strips

open access: yesAgricultural and Forest Entomology, EarlyView.
We applied three thiamethoxam spray treatments to buckwheat border strips: control (no nearby spray), drift (adjacent peach trees directly sprayed) and direct spray (buckwheat and peaches directly sprayed). Drift‐treated buckwheat received about 1.4% the amount of thiamethoxam as direct‐spray buckwheat. This amount has no lethal effects on parasitoids,
