The value of regeneration for insect fauna associated with leaf litter in the Brazilian savanna: A comparative study of biomass and trophic structure

Annals of Applied Biology, EarlyView.
This study demonstrates the ecological value of natural regeneration in the Brazilian Cerrado by analysing the biomass, richness and trophic structure of leaf litter insects across pasture (P), regenerating (R) and native (N) areas. We found that R areas supported insect communities more similar to N habitats than to Ps, with higher richness, greater ...

Evaluating insect-host interactions as a driver of species divergence in palm flower weevils

Communications Biology, 2020
de Medeiros and Farrell test how insect-host interactions influence species divergence in phytophagous insects. Using ddRAD-seq data and hierarchical modelling, they demonstrate, surprisingly, that antagonistic interactions between insect and host do not

Host preferences of non‐native Acalolepta aesthetica (Coleoptera: Cerambycidae) on the Island of Hawaiʻi

Agricultural and Forest Entomology, EarlyView.
Acalolepta aesthetica is a non‐native cerambycid established on the Island of Hawaiʻi. We show its preferred hosts are woody species that are highly valued for agricultural, horticultural and cultural uses. We used a resource selection function to estimate host preferences and found that kukui (Aleurites moluccanus), the state tree, was preferred ...

Food as a factor determining the physiological state of populations of the phytopagous pests of agricultural crops

Овощи России
Relevance. Trophic relationships along with competition and mutualism are the most basic and significant interactions in ecosystems. To develop, survive, and multiply, insects need to consume a certain amount of nutrients at a certain ratio.

Herbivory increases diversification across insect clades. [PDF]

, 2015
Insects contain more than half of all living species, but the causes of their remarkable diversity remain poorly understood. Many authors have suggested that herbivory has accelerated diversification in many insect clades. However, others have questioned

A New Experimental Setup to Study the Olfactory Behaviour of Trichogramma Egg Parasitoids

Entomologia Experimentalis et Applicata, EarlyView.
We developed an experimental setup to assess odor‐induced egg‐laying behavior in tiny egg‐parasitoid wasps. This Y‐shaped olfactometer, coupled with an AI‐based image‐recognition model, automatically quantifies egg parasitism by Trichogramma wasps. Olfactory‐driven egg‐laying preferences were analyzed using Bayesian inference.

Foodplant Processing Adaptations in Four \u3ci\u3eHyalophora\u3c/i\u3e Species (Lepidoptera: Saturniidae): Regional and Taxonomic Specialization [PDF]

, 2017
To determine whether local populations of four Hyalophora species (Lepidoptera: Satumiidae) had improved survival or were physiologically adapted for rapid and/or efficient growth on their local hosts, a series of larval feeding studies were conducted ...

Design, Training, and Field Validation of a YOLOv8‐Based Automated Trap for Remote Detection of Codling Moth, Cydia pomonella

Entomologia Experimentalis et Applicata, EarlyView.
We developed and field‐validated a fully automated trap for Cydia pomonella monitoring, combining a camera with a YOLOv8 object‐detection model for remote insect identification. In controlled laboratory validation, the model showed strong performance (precision 0.77, recall 0.83), with moderate reductions under field conditions. Across six experiments,

Species Composition of Phytophagous and Entomophagous Insects and Mites on Soybeans in Krasnodar and Stavropol Territories, Russia

Agronomy
Soybeans are a valuable crop in many countries of the world. To obtain stable yields, it is necessary to consider the activities of arthropods, both beneficial and destructive. The results of this study indicate high biodiversity.

Leptocybe invasa Fisher & La Salle, 2004 and Ophelimus maskelli Haliday, 1844 - two new records of gall forming Eulophidae from Malta (Hymenoptera, Chalcidoidea) [PDF]

, 2012
The Eulophidae (Hymenoptera, Chalcidoidea) currently accommodates more than 4,000 described species worldwide in some 300 genera (noyES, 2003). In Europe, the family is represented by about 1,100 species (GAuld & Bolton, 1988).
