Co‐phylogeny and biogeography of the myrmecophilous beetle Paussus favieri (Carabidae, Paussinae) and its host ant Pheidole pallidula (Hymenoptera, Myrmicinae)

open access: yesInsect Science, EarlyView.
Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐

Bioavailability of pesticides in freshwater sediments [PDF]

open access: yes, 2007
In ecological risk assessment standardized sediment toxicity tests are used to predict the hazard of chemicals for sediment-living organisms. Feeding is a prerequisite in these long-term tests to avoid starvation of test organisms.

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.

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.

Integration of epigenetics into ecotoxicology: insights and fundamental research needs. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT Epigenetics refers to heritable changes in genome function that occur without direct alterations to the DNA sequence. A multitude of environmental contaminants can influence the epigenetic marks of a genome. Changes of epigenetic marks including DNA methylation, histone modifications, and non‐coding RNAs can induce alterations at the gene ...

The shibirets4 mutation causes temperature sensitive paralytic and lethal phenotypes in the Queensland fruit fly, Bactrocera tryoni

open access: yesInsect Science, EarlyView.
Abstract Bactrocera tryoni, the Queensland fruit fly, is among the most damaging insect pests to the Australian horticultural industry as larvae infest ripening fruits or vegetables prior to harvest. Genetic biocontrol using Sterile Insect Technique (SIT) programs have been used to successfully suppress populations, via mass release of factory‐reared ...

Phytoassessment of Vetiver grass enhanced with EDTA soil amendment grown in single and mixed heavy metal–contaminated soil [PDF]

open access: yes, 2019
Over the years, ethylene-diamine-tetra-acetate (EDTA) has been widely used for many purposes. However, there are inadequate phytoassessment studies conducted using EDTA in Vetiver grass. Hence, this study evaluates the phytoassessment (growth performance,

CRISPR/Cas9‐mediated mutagenesis of the white‐eye gene in the tephritid pest Bactrocera zonata

open access: yesInsect Science, EarlyView.
Abstract Bactrocera zonata is a highly invasive agricultural pest that causes extensive damage to fruit crops. The Sterile Insect Technique (SIT), a species‐specific and environmentally friendly pest control method, significantly benefits from the availability of Genetic Sexing Strains (GSSs) that enable efficient mass production of males for sterile ...

Sequence and expression analysis of potential spermatogenesis‐specific gene cognates in the Caribbean fruit fly, Anastrepha suspensa

open access: yesInsect Science, EarlyView.
Abstract The sterile insect technique (SIT) is a highly effective biologically‐based method for the suppression of many insect pest populations. SIT efficacy could be improved by methods of male sterilization that avoid the use of irradiation that can result in diminished fitness and mating competitiveness.
