The predatory behavior of ants: an impressive panoply of morphological adaptations

open access: yesInsect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Combining Plant Pathogenic Fungi and the Leaf-Mining Fly, Hydrellia pakistanae, Increases Damage to Hydrilla [PDF]

open access: yes, 2003
Four fungal species, F71PJ Acremonium sp., F531 Cylindrocarpon sp., F542, Botrytis sp., and F964 Fusarium culmorum [Wm. G. Sm.] Sacc. were recovered from hydrilla [ Hydrilla verticillata (L.

Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

open access: yesInsect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Experimental warming increases herbivory by leaf‐chewing insects in an alpine plant community

open access: yesEcology and Evolution, 2016
Climate warming is predicted to affect species and trophic interactions worldwide, and alpine ecosystems are expected to be especially sensitive to changes.

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

open access: yesInsect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Do tissue carbon and nitrogen limit population growth of weevils introduced to control waterhyacinth at a site in the Sacramento-San Joaquin Delta, California? [PDF]

open access: yes, 2004
Waterhyacinth (Eichhornia crassipes(Mart.) Solms), is a serious problem in the Sacramento Delta. Two weevil species (Neochetina bruchi Hustache and N. eichhorniae Warner) have been introduced as biological control agents. The purpose of this study was

An unbiased approach elucidates variation in (S)-(+)-linalool, a context-specific mediator of a tri-trophic interaction in wild tobacco

open access: yes, 2019
Plant volatile organic compounds (VOCs) mediate many interactions, and the function of common VOCs is especially likely to depend on ecological context.

Multi‐Omics Analysis Reveals Coordinated Adaptations in Genes, Metabolism, and Gut Microbiota Underpinning Herbivory in Lordiphosa Flies

open access: yesIntegrative Zoology, EarlyView.
Multi‐omics analysis reveals that herbivorous adaptation in Lordiphosa flies arises from coordinated interactions across the genome, transcriptome, and gut microbiota: genomic expansions of detoxification (e.g., cytochrome P450s) and carbohydrate metabolism gene families, transcriptomic upregulation of energy pathways like lipid oxidation and ...

Development and Reproduction of Nesidiocoris tenuis Reuter (Heteroptera: Miridae): The Effect of Temperature, Origin and Food

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Nymphal development took longer at 25°C than 30°C, and the Greek N. tenuis population developed more slowly than the commercial population. Nymphs clearly preferred E. kuehniella eggs over Artemia sp. cysts when both were offered equally. Egg production increased at 30°C, while female longevity declined.

Forage Plant Host and Early Feeding Choices Affect Spodoptera litura Feeding, Development and Egg‐Laying

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We assessed Spodoptera litura (Lepidoptera: Noctuidae) performance on five common pasture plant species. Larvae consumed more dock, plantain and chicory per day than red or white clover, but with lower conversion efficiencies. Feeding on red clover reduced weights and egg laying, and lengthened development times compared with plantain.
