Ancient and diverged TGF-β signaling components in Nasonia vitripennis [PDF]

open access: yesDevelopment Genes and Evolution, 2014
The transforming growth factor beta (TGF)-β signaling pathway and its modulators are involved in many aspects of cellular growth and differentiation in all metazoa. Although most of the core components of the pathway are highly conserved, many lineage-specific adaptations have been observed including changes regarding paralog number, presence and ...

The pace and shape of ant ageing

open access: yesBiological 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 ...

Are ticks venomous animals? [PDF]

open access: yes, 2017
[Introduction]: As an ecological adaptation venoms have evolved independently in several species of Metazoa. As haematophagous arthropods ticks are mainly considered as ectoparasites due to directly feeding on the skin of animal hosts. Ticks are of major

Whole genome shotgun phylogenomics resolve the diving beetle tree of life

open access: yesSystematic 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,

Exploring Plant α‐Amylase Inhibitors: Mechanisms and Potential Application for Insect Pest Control

open access: yesBiotechnology 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 ...

Courtship Is a Major Factor of Mating‐Shortened Male Lifespan in an Egg Parasitoid

open access: yesEcology 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.

OGS2: genome re-annotation of the jewel wasp Nasonia vitripennis

open access: yesBMC Genomics, 2016
Nasonia vitripennis is an emerging insect model system with haplodiploid genetics. It holds a key position within the insect phylogeny for comparative, evolutionary and behavioral genetic studies. The draft genomes for N. vitripennis and two sibling species were published in 2010, yet a considerable amount of transcriptiome data have since been ...

The Post-mating Switch in the Pheromone Response of Nasonia Females Is Mediated by Dopamine and Can Be Reversed by Appetitive Learning

open access: yesFrontiers in Behavioral Neuroscience, 2018
The olfactory sense is of crucial importance for animals, but their response to chemical stimuli is plastic and depends on their physiological state and prior experience.

Nestboxes as habitat for insects, especially for flies and their parasitoids [PDF]

open access: yes, 2012
Aus Nistkästen wurden nach dem Ausfliegen der Vögel etwa 500 Nester entnommen und die darin vorhandenen Insekten herausgesucht oder mit einem Eklektor abgesammelt.
