Pollinator is a housemate: Aeginetia indica, a parasite on Miscanthus sinensis, is pollinated by Ceratina bees nesting in its host

Plant Species Biology, EarlyView.
Aeginetia indica is a parasitic plant on Miscanthus sinensis. Through interval photography and direct observation, we identified Ceratina flavipes as its sole pollinator, which nests inside the stem of M. sinensis. This pollination system, which involves a mutual relationship between a parasitic plant and an insect inhabiting the same host plant, has ...

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 ...

Ecological impact and population status of non-native bees in a Brazilian urban environment

Revista Brasileira de Entomologia
The introduction of species is an important global threat to native ecosystems and yet little is known about invasion risks of non-native bees. Moreover, urbanization is increasing rapidly around the world with impact on the bee fauna.

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 ...

Pollinator visits increase with bloom amount but decline with building height on extensive green roofs

Insect Conservation and Diversity, EarlyView.
Pollinator abundance and species richness decline with building height. Although our study was limited to eight sites, it emphasises the importance of extensive green roofs (EGRs) on low‐rise buildings. Bee abundance and species richness increased with stonecrop bloom amount, but communities determined from distinct stonecrop species were more alike to

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 ...
