A Set of Novel Venom Proteins Enables Parasitoid Wasps to Exploit Older Hosts and Coexist with Competitors

Advanced Science, Volume 13, Issue 4, 19 January 2026.
This study elucidates a molecular mechanism enabling species coexistence between parasitoid wasps, showing how Asobara japonica uses a set of novel venom proteins to delay host development and exploit older hosts, thereby achieving temporal niche partitioning with Leptopilina drosophilae. Abstract Interspecific competition can drive species coexistence

Experimental Parasitism of Synanthropic Flies (Musca domestica, Lucilia sericata, and Sarcophaga heamorrhoidalis) by Parasitoid Wasps (Nasonia vitripennis, Spalangia nigroaenea, and Pachycrepoideus vindemmiae)

Journal of Mazandaran University of Medical Sciences, 2019
Background and purpose: One of the most popular methods to control the synanthropic flies is using parasitoid wasps. The aim of this study was to estimate the experimental parasitism rates of pupae of Musca domestica, Lucilia sericata, and Sarcophaga ...

Gene expression changes associated with the evolutionary loss of a metabolic trait: lack of lipogenesis in parasitoids

BMC Genomics, 2019
Background Trait loss is a pervasive phenomenon in evolution, yet the underlying molecular causes have been identified in only a handful of cases. Most of these cases involve loss-of-function mutations in one or more trait-specific genes.

Deciphering proteomic signatures of early diapause in Nasonia. [PDF]

PLoS ONE, 2009
Insect diapause is an alternative life-history strategy used to increase longevity and survival in harsh environmental conditions. Even though some aspects of diapause are well investigated, broader scale studies that elucidate the global metabolic ...

Genetics of cuticular hydrocarbon differences between males of the parasitoid wasps Nasonia giraulti and Nasonia vitripennis [PDF]

Heredity, 2010
Many insects rely on cuticular hydrocarbons (CHCs) as major recognition signals between individuals. Previous research on the genetics of CHCs has focused on Drosophila in which the roles of three desaturases and one elongase were highlighted. Comparable studies in other insect taxa have not been conducted so far.

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 ...

Sperm Depletion and Mating Behavior in the Parasitoid Wasp \u3ci\u3eSpalangia Cameroni\u3c/i\u3e (Hymenoptera: Pteromalidae) [PDF]

, 2018
Mating behavior was examined in the parasitoid wasp Spalangia cameroni. Males attempted copulation with both virgins and already mated females. Males attempted copulation regardless of whether they still had sperm. Already mated females rejected attempts

Patterning the dorsal–ventral axis of the wasp Nasonia vitripennis

Developmental Biology, 2013
Regulatory networks composed of interacting genes are responsible for pattern formation and cell type specification in a wide variety of developmental contexts. Evolution must act on these regulatory networks in order to change the proportions, distribution, and characteristics of specified cells.

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.

Effects on microhymenopteran progeny of different host exposure periods (Chrysomya megacephala, Calliphoridae) to the parasitoid wasp Nasonia vitripennis (Hymenoptera: Pteromalidae)

Brazilian Archives of Biology and Technology, 2010
To test the assumption that exposure of the host to parasitoid for long periods could provoke superparasitism, the aim of this work was to test the consequences on the immature development time, productivity of parasitoids per pupa, sex ratio and rate of
