The pace and shape of ant ageing
Biological Reviews, Volume 100, Issue 5, Page 2071-2083, October 2025.ABSTRACT Ants have been proposed as good models to study ageing and the effects of extrinsic mortality because of their long lifespans and plasticity of ageing within species. We discuss how age‐dependent extrinsic mortality might influence queen lifespan, and how the effect of age‐independent extrinsic mortality needs further study, accounting for ...

Conserved developmental processes and the formation of evolutionary novelties: examples from butterfly wings [PDF]
, 2008 The origin and diversification of evolutionary novelties—lineage-specific traits of new adaptive value—is one of the key issues in evolutionary developmental biology. However, comparative analysis of the genetic and developmental bases of such traits can

Whole genome shotgun phylogenomics resolve the diving beetle tree of life
Systematic Entomology, Volume 50, Issue 4, Page 940-974, October 2025.A new and strongly supported phylogeny of diving beetles (Dytiscidae) is presented using the largest genomic dataset to date. Laccophilinae and Coptotominae + Lancetinae are early diverging lineages excluded from a large monophyletic clade comprising the remaining eight subfamilies. We identify seven remaining problems in the backbone of the phylogeny,

Male-killing bacteria in insects: mechanisms, incidence and implications [PDF]
, 2000 Bacteria that are vertically transmitted through female hosts and kill male hosts that inherit them were first recorded in insects during the 1950s. Recent studies have shown these "male-killers" to be diverse and have led to a reappraisal of the biology

A chimeric gene paternally instructs female sex determination in the haplodiploid wasp Nasonia
Science, 2020 Paternal factor specifies female wasps Not all animals have specialized sex chromosomes to determine their sex. In hymenopteran insects, for example, unfertilized eggs become males and fertilized eggs become females.

Journal of Avian Biology, Volume 2025, Issue 5, September 2025.Animals breed at times of the year that ensure offspring production and growth during favorable periods. DNA methylation is one mechanism by which expression of genes necessary for reproduction may be regulated, enabling expression only at appropriate times. Much work on seasonal breeding in vertebrates has focused on the neuroendocrine system, however

Exploring Plant α‐Amylase Inhibitors: Mechanisms and Potential Application for Insect Pest Control
Biotechnology Journal, Volume 20, Issue 8, August 2025.Graphical Abstract and Lay Summary In this study, we address the importance of α‐amylases in insect pests, the possible biochemical role of α‐amylase inhibitors in plant resistance to insect pests, the molecular relationships between plant α‐amylase inhibitors and insect α‐amylases, and the biotechnological potential of proteinaceous α‐amylase ...

Field Collection of Nasonia (Parasitoid Wasp) Using Baits [PDF]
Cold Spring Harbor Protocols, 2009 INTRODUCTIONThis protocol describes a standard method for collecting Nasonia wasps using “flyliver”: liver remains fed upon by fly maggots (e.g., Sarcophaga) and collected after the mature larvae have dispersed. The flyliver, which contains a volatile substance that is very attractive to the wasps, is placed in a large (~15-cm2) mesh bag hung in ...

Courtship Is a Major Factor of Mating‐Shortened Male Lifespan in an Egg Parasitoid
Ecology and Evolution, Volume 15, Issue 8, August 2025.Mating is vital for population survival but often leads to reduced post‐mating longevity in both sexes. In many insects, sperm‐related factors are thought to cut male longevity, while in Anastatus disparis, mating also affects male longevity, with courtship being the main cause. Transcriptomic analyses of A.
