Dual mode of embryonic development is highlighted by expression and function of Nasonia pair-rule genes

open access: yeseLife, 2014
Embryonic anterior–posterior patterning is well understood in Drosophila, which uses ‘long germ’ embryogenesis, in which all segments are patterned before cellularization.

Silencing of two insulin receptor genes disrupts nymph-adult transition of alate brown citrus aphid [PDF]

open access: yes, 2017
Insulin receptors play key roles in growth, development, and polymorphism in insects. Here, we report two insulin receptor genes (AcInR1 and AcInR2) from the brown citrus aphid, Aphis (Toxoptera) citricidus.

Symbiosis As The Way Of Eukaryotic Life: The Dependent Co-Origination Of The Body [PDF]

open access: yes, 2014
Molecular analyses of symbiotic relationships are challenging our biological definitions of individuality and supplanting them with a new notion of normal part whole relationships. This new notion is that of a \u27holobiont\u27, a consortium of organisms

A new component of the Nasonia sex determining cascade is maternally silenced and regulates transformer expression. [PDF]

open access: yesPLoS ONE, 2013
Although sex determination is a universal process in sexually reproducing organisms, sex determination pathways are among the most highly variable genetic systems found in nature.

The genomes of two key bumblebee species with primitive eusocial organization [PDF]

open access: yes, 2015
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies.

Latitudinal variation in circadian rhythmicity in Nasonia vitripennis [PDF]

open access: yesBehavioral Sciences, 2019
ABSTRACTMany physiological processes of living organisms show circadian rhythms, governed by an endogenous clock. This clock has a genetic basis and is entrained by external cues such as light and temperature. Other physiological processes exhibit seasonal rhythms, that are also responsive to light and temperature.

Genomics of sex allocation in the parasitoid wasp Nasonia vitripennis

open access: yesBMC Genomics, 2020
Background Whilst adaptive facultative sex allocation has been widely studied at the phenotypic level across a broad range of organisms, we still know remarkably little about its genetic architecture.

Prior Mating Experience Modulates the Dispersal of Drosophila in Males More Than in Females [PDF]

open access: yes, 2011
Cues from both an animal’s internal physiological state and its local environment may influence its decision to disperse. However, identifying and quantifying the causative factors underlying the initiation of dispersal is difficult in uncontrolled ...

Male Sex Pheromone of the Parasitoid Wasp Urolepis rufipes Demonstrates Biosynthetic Switch Between Fatty Acid and Isoprenoid Metabolism Within the Nasonia Group

open access: yesFrontiers in Ecology and Evolution, 2019
Sex pheromones play a crucial role in the mate finding process of insects. The information has to be encoded in a species specific manner to avoid fitness costs due to courtship by or even mismating with closely related species.

Sex biased expression and co-expression networks in development, using the hymenopteran Nasonia vitripennis. [PDF]

open access: yesPLoS Genetics, 2020
Sexual dimorphism requires regulation of gene expression in developing organisms. These developmental differences are caused by differential expression of genes and isoforms.
