The role of artificial nesting boxes and birds’ nests in maintaining vital activity of the Vespidae and Apidae families

Біологічні студії, 2022
Background. During 2019‒2021, from the first decade of March to the third decade of July on the territory of northeastern Ukraine, ornithological studies on hollow-nesting birds populating artificial nestings were carried out.

The transformer gene controls sexual development in Drosophila suzukii

Insect Science, EarlyView.
The transformer gene plays a key role in the genetic pathway for sexual development in Drosophila suzukii Abstract The genetic network of sex determination in the model organism Drosophila melanogaster was investigated in great detail. Such knowledge not only advances our understanding of the evolution and regulation of sexual dimorphism in insects ...

Expression of heat-shock protein genes in Apis mellifera meda (Hymenoptera: Apidae) after exposure to monoterpenoids and infestation by Varroa destructor mites (Acari: Varroidae)

European Journal of Entomology, 2017
Heat shock proteins (hsps) protect proteins in eukaryotic cells from damage. Expression of hsps in insects subject to different environmental stimuli is poorly characterized.

Genetic differentiation and adaptive evolution of buff‐tailed bumblebees in Asia

Insect Science, EarlyView.
This study investigates the genetic differentiation and local adaptation of the buff‐tailed bumblebee (Bombus terrestris) across its European and Asian populations. Using whole‐genome resequencing, we identified distinct genetic differences between populations, with Asian B. terrestris representing a unique genetic resource.

A survey of the genus Ceratina Latreille (Hymenoptera: Apidae) in northern Iran, with three new records [PDF]

Journal of Insect Biodiversity and Systematics, 2016
A field survey of the bee fauna was conducted in the north of Iran during 2009 to 2015. Special concern was given to the tribe Ceratinini (Hymenoptera; Apidae). Ten species of the genus Ceratina were collected and identified in the present study.

Stress in dipteran insects mass‐reared for sterile insect technique applications

Insect Science, EarlyView.
The connections between biotic and abiotic stress affecting mass‐reared dipteran insects and the associated stress and immunological responses. Numbers indicate the order in which the topics are discussed in this review. Abstract Stress may be viewed as the disturbance of homeostasis of an organism.

Dispersion of Bumblebee Bombus Semenoviellus Skorikov (Hymenoptera, Apidae) in Poland

Journal of Apicultural Science, 2020
The aim of the study is to present all distribution sites of Bombus semenoviellus in Poland reported between 1988 and 2019. The increase of species dispersion was concluded, especially in the central part of the country, as well as the occurrence in the ...

Ecological factors underlying the spatiotemporal dynamics in a key forest beetle pollinator Facteurs écologiques à la base de la dynamique spatio‐temporelle d'un important coléoptère forestier pollinisateur

Agricultural and Forest Entomology, EarlyView.
Eusphalerum, an understudied beetle pollinator in North America, comprises over 50% of beetle specimens collected using flight‐intercept traps in forests across New Brunswick, Canada. In a study investigating its phenology, congeneric aggregation and population dynamics, we demonstrated that Eusphalerum exhibits unique phenology distinct from other ...

Chemotaxonomical characterisation of males of Bombus lucorum (Hymenoptera: Apidae) collected in the Czech Republic

European Journal of Entomology, 2001
Labial gland secretions of 26 males of the bumblebee Bombus lucorum (L.), collected in the Czech Republic, were analysed. The secretions consisted of 60 compounds; ethyl (Z)-9-tetradecenoate was the main component (average 53%). Although the males varied

Pharmacophagy in insects: Ecological and evolutionary perspectives on the non‐nutritional use of plant specialized metabolites

Entomologia Experimentalis et Applicata, EarlyView.
Insects interact with plants not only for nutrition but also to actively seek plant specialized metabolites (PSMs) for chemical defense, reproduction, and self‐medication—a behavior known as pharmacophagy. This review examines how insects across diverse orders acquire PSMs from both food and non‐food plants for non‐nutritional benefits.
