Microhymenoptera in roadside verges and the potential of arthropod‐friendly mowing for their preservation

Journal of Applied Entomology, Volume 147, Issue 10, Page 1035-1044, December 2023., 2023
Abstract The worldwide decline of insects is one of the major challenges for humankind. One of its main drivers is intensive farming, which reduces habitats and food resources for insect populations and causes direct mortality by pesticides. In addition, mowing of grassland poses another threat to insects, especially when it is done frequently, such as

Host–enemy interactions provide limited biotic resistance for a range‐expanding species via reduced apparent competition

Diversity and Distributions, Volume 29, Issue 11, Page 1355-1370, November 2023., 2023
Abstract Aim As species' ranges shift poleward in response to anthropogenic change, they may lose antagonistic interactions if they move into less diverse communities, fail to interact with novel populations or species effectively, or if ancestral interacting populations or species fail to shift synchronously. We leveraged a poleward range expansion in

Absence of complementary sex determination in two Leptopilina species (Figitidae, Hymenoptera) and a reconsideration of its incompatibility with endosymbiont‐induced thelytoky

Insect Science, Volume 29, Issue 3, Page 900-914, June 2022., 2022
Under complementary sex determination (CSD), if the fertilized eggs are homozygous, they develop into diploid males. Forms of thelytoky induced by endosymbiont lead to genome homozygosity as well. By presenting our results in two cynipid wasp species Leptopilina heterotoma and Leptopilina clavipes, we discuss the presumed incompatibility between CSD ...

DiversityScanner: Robotic handling of small invertebrates with machine learning methods

Molecular Ecology Resources, Volume 22, Issue 4, Page 1626-1638, May 2022., 2022
Abstract Invertebrate biodiversity remains poorly understood although it comprises much of the terrestrial animal biomass, most species and supplies many ecosystem services. The main obstacle is specimen‐rich samples obtained with quantitative sampling techniques (e.g., Malaise trapping).

A maximalist approach to the systematics of a biological control agent: Gryon aetherium Talamas, sp. nov. (Hymenoptera, Scelionidae) [PDF]

Journal of Hymenoptera Research, 2021
A morphological and molecular analysis of Gryon Haliday (Platygastroidea, Scelionidae) was conducted to provide a taxonomic and phylogenetic context for a species under evaluation as a biological control agent of Bagrada hilaris (Burmeister) (Hemiptera ...

Molecular analysis reveals Latonius planus Kononova to be a derived species of Trissolcus Ashmead [PDF]

Journal of Hymenoptera Research, 2021
The monotypic genus Latonius Kononova, 1982 (Platygastroidea, Scelionidae), was described from a single female specimen collected in southern Ukraine. It somewhat resembles Trissolcus Ashmead but has a distinctive claval formula.
