Chromosome-Level Assembly of Drosophila bifasciata Reveals Important Karyotypic Transition of the X Chromosome

G3: Genes, Genomes, Genetics, 2020
The Drosophila obscura species group is one of the most studied clades of Drosophila and harbors multiple distinct karyotypes. Here we present a de novo genome assembly and annotation of D. bifasciata, a species which represents an important subgroup for

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

Drosophila Sexual Attractiveness in Older Males Is Mediated by Their Microbiota

Microorganisms, 2020
Age is well known to be a basis for female preference of males. However, the mechanisms underlying age-based choices are not well understood, with several competing theories and little consensus.

Thirty Years of the Biology of Spermatozoa: The Rise and Future of an Evolutionary Paradigm

Ecology and Evolution, Volume 16, Issue 1, January 2026.
A sperm bundle taken from the seminal vescicles of the dung beetle, Onthophagus taurus. Image credit: Leigh W. Simmons. ABSTRACT In the early 1970s, Geoff Parker recognised that because females frequently mate with multiple males, competition for fertilizations will impose significant sexual selection on males and their ejaculates.

Extensive divergence of transcription factor binding in Drosophila embryos with highly conserved gene expression. [PDF]

PLoS Genetics, 2013
To better characterize how variation in regulatory sequences drives divergence in gene expression, we undertook a systematic study of transcription factor binding and gene expression in blastoderm embryos of four species, which sample much of the ...

Sexual conflict as a constraint on asexual reproduction: an empirical review

Biological Reviews, Volume 100, Issue 6, Page 2681-2706, December 2025.
ABSTRACT Theory predicts that facultatively asexual animals, which can leverage the advantages of both sexual and asexual reproduction, should outcompete obligately sexual and obligately asexual animals. Yet, paradoxically, obligate sexual reproduction predominates in many animal lineages, while the most flexible form of facultative asexuality (i.e ...

Determinants of mating success in a lek‐mating species

Agricultural and Forest Entomology, Volume 27, Issue 4, Page 643-652, November 2025.
Abstract Leks are male‐biased aggregations formed for mating, where sperm is the only resource acquired by visiting females. One of the many advantages of leks is the possibility to efficiently assess the quality of potential mates by comparing aggregated individuals of the same sex with one another. When direct mate choice occurs in a lekking species,

Epistasis among Drosophila persimilis factors conferring hybrid male sterility with D. pseudoobscura bogotana. [PDF]

PLoS ONE, 2010
The Bateson-Dobzhansky-Muller model posits that hybrid incompatibilities result from genetic changes that accumulate during population divergence.

Transcriptomic Analysis and Comparative Analysis of Gene Families Related to Environmental Adaptation in Two Grylloblattodea Species: Galloisiana sinensis and Grylloprimevala jilina

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Notoptera, a singular ancient insect lineage, is vital for exploring insect environmental adaptation, evolution, and its geological history link, recognized as a national first‐class protected animal. Comparing environmental adaptation genes in Galloisiana sinensis and Grylloprimevala jilina, closely related yet habitat‐disparate species, illuminates ...

Evolution of Phospholipase A2 in Bees and Flies

Ecology and Evolution, Volume 15, Issue 10, October 2025.
This study investigated the evolution of the PLA2 gene in bees and flies and compared the evolutionary rate between them, which denotes the toxic group and the non‐toxic group. The results showed that PLA2 was under purifying selection and that an accelerated evolution of PLA2 occurred in the toxic group when compared with the non‐toxic group ...
