Arthropod niche differentiation linked to grazing‐induced sward islets in intensively managed agricultural pasture

Insect Conservation and Diversity, EarlyView.
In a given number of samples, grassland sward islets contain more species of arthropods than the surrounding sward. When corrected for abundance, there is no difference in species richness, suggesting that the effect of islets might purely be to concentrate arthropods. The community structure differences indicated by non‐metric multidimensional scaling

The complete mitochondrial genome and phylogenetic analysis of Euurobracon yokahamae (Hymenoptera: Braconidae)

Mitochondrial DNA. Part B. Resources, 2022
Euurobracon yokahamae is a parasitoid wasp found solely in Asia, and is endangered in some countries. The complete mitochondrial DNA sequence of E. yokahamae was sequenced using next-generation sequencing (NGS). The mitogenome of this species is 14,974bp

Field Host Range of Apanteles opuntiarum (Hymenoptera: Braconidae) in Argentina, a Potential Biocontrol Agent of Cactoblastis cactorum (Lepidoptera: Pyralidae) in North America

, 2015
Summary Field exploration in Argentina for cactophagous lepidopteran hosts parasitized by the recently described braconid parasitoid Apanteles opuntiarum Martínez & Berta (Hymenoptera: Braconidae) revealed a host range restricted to Cactoblastis cactorum

New records and new species of Miracinae (Hymenoptera: Braconidae) from Australia and Papua New Guinea, with a key to world Mirax species

Austral Entomology, Volume 65, Issue 1, February 2026.
Abstract The genera of Miracinae, currently in something of a state of flux, are discussed with respect to their morphological and molecular attributes. Centistidea Rohwer, 1914 is treated provisionally as a valid genus, distinct from Mirax Haliday, 1833, based partly on propodeal morphology, though this is acknowledged to be an unstable character ...

Local species‐specific effect of trees and shrubs on the incidence of the millet head miner, Heliocheilus albipunctella (Lepidoptera, Noctuidae)

Agricultural and Forest Entomology, Volume 28, Issue 1, Page 38-48, February 2026.
Abstract Understanding the interactions between crop pests, natural enemies and semi‐natural habitats in agricultural landscapes is crucial for developing ecology‐based pest management in agroecosystems. In the present study, we investigated the local‐scale species‐specific effect of tree and shrub cover and diversity on the incidence and natural pest ...

Vegetation biomass and landscape context influence web‐building spider dietary breadth in urban vacant lots

Ecological Entomology, Volume 51, Issue 1, Page 126-140, February 2026.
Spider dietary breadth and overlap increased with imperviousness, suggesting that prey and spiders are concentrating in vacant lots in these landscapes. Higher vegetation biomass, which results from reduced mowing frequency, was associated with increased dietary breadth and shared prey between spiders.

A Set of Novel Venom Proteins Enables Parasitoid Wasps to Exploit Older Hosts and Coexist with Competitors

Advanced Science, Volume 13, Issue 4, 19 January 2026.
This study elucidates a molecular mechanism enabling species coexistence between parasitoid wasps, showing how Asobara japonica uses a set of novel venom proteins to delay host development and exploit older hosts, thereby achieving temporal niche partitioning with Leptopilina drosophilae. Abstract Interspecific competition can drive species coexistence

Molecular and morphological phylogeny of the parasitic wasp genus Yelicones (Hymenoptera: Braconidae: Rogadinae)

European Journal of Entomology, 2005
Phylogenetic relationships of the braconid wasp genus Yelicones Cameron are studied using the D2-D3 region of the nuclear 28S rRNA gene, both alone and simultaneously with morphology. The results support a morphology-based phylogeny, presented elsewhere,

Meta‐analysis on effects of Bt‐maize on nontarget invertebrates – Data transportability across continents

PLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 365-376, January 2026.
Maize varieties producing insecticidal proteins from Bacillus thuringiensis (Bt) have become an important component of integrated pest management worldwide. For regulatory approval of such plants, risks to the environment need to be assessed. To make such assessments less expensive and time‐consuming, conclusions drawn from data collected in one region

Adaptive preferential selection of female coccinellid hosts by the parasitoid wasp Dinocampus coccinellae (Hymenoptera: Braconidae)

European Journal of Entomology, 2006
Females of the parasitoid wasp Dinocampus coccinellae are known to parasitise both male and female coccinellid hosts. It is suggested that female hosts provide more resources for developing wasp larvae because they tend to be larger than male hosts, and ...
