Journal of Insect Science, 2022 Haplo-diploid sex determination in the parasitoid wasp, Nasonia vitripennis (Walker), allows females to adjust their brood sex ratios. Females influence whether ova are fertilized, producing diploid females, or remain unfertilized, producing haploid ...

Journal of Developmental Biology, 2022 The Toll signaling pathway is the main source of embryonic DV polarity in the fly Drosophila melanogaster. This pathway appears to have been co-opted from an ancestral innate immunity system within the insects and has been deployed in different ways ...

Estimating (Non)Linear Selection on Reaction Norms: A General Framework for Labile Traits
Ecology and Evolution, Volume 15, Issue 10, October 2025.It remains difficult to empirically estimate nonlinear selection on individual reaction norms, inhibiting robust tests of adaptive theory and accurate predictions of phenotypic evolution for labile traits. To address this challenge, we propose generalized multilevel models for estimating stabilizing, disruptive, and correlational selection on the ...

Haploid Females in the Parasitic Wasp Nasonia vitripennis [PDF]
Science, 2007 The insect order of Hymenoptera (ants, bees, sawflies, and wasps) consists almost entirely of haplodiploid species. Under haplodiploidy, males develop from unfertilized eggs and are haploid, whereas females develop from fertilized eggs and are diploid. Although diploid males commonly occur, haploid females have never been reported.

Non-coding changes cause sex-specific wing size differences between closely related species of Nasonia. [PDF]
PLoS Genetics, 2010 The genetic basis of morphological differences among species is still poorly understood. We investigated the genetic basis of sex-specific differences in wing size between two closely related species of Nasonia by positional cloning a major male-specific

Infection dynamics of endosymbionts that manipulate arthropod reproduction
Biological Reviews, Volume 100, Issue 5, Page 1787-1812, October 2025.ABSTRACT A large proportion of arthropod species are infected with endosymbionts, some of which selfishly alter host reproduction. The currently known forms of parasitic reproductive manipulations are male‐killing, feminization, cytoplasmic incompatibility, parthenogenesis induction and distortion of sex allocation.

Comparative susceptibility of mosquito populations in North Queensland, Australia to oral infection with dengue virus. [PDF]
, 2014 Dengue is the most prevalent arthropod-borne virus, with at least 40% of the world's population at risk of infection each year. In Australia, dengue is not endemic, but viremic travelers trigger outbreaks involving hundreds of cases.
