Sex‐biased gene content is associated with sex chromosome turnover in Danaini butterflies

Molecular Ecology, Volume 33, Issue 24, December 2024.
Abstract Sex chromosomes play an outsized role in adaptation and speciation, and thus deserve particular attention in evolutionary genomics. In particular, fusions between sex chromosomes and autosomes can produce neo‐sex chromosomes, which offer important insights into the evolutionary dynamics of sex chromosomes. Here, we investigate the evolutionary

Targeted mutagenesis using CRISPR-Cas9 in the chelicerate herbivore Tetranychus urticae [PDF]

, 2020
The use of CRISPR-Cas9 has revolutionized functional genetic work in many organisms, including more and more insect species. However, successful gene editing or genetic transformation has not yet been reported for chelicerates, the second largest group ...

Intra‐species quantification reveals differences in activity and sleep levels in the yellow fever mosquito, Aedes aegypti

Medical and Veterinary Entomology, Volume 38, Issue 4, Page 482-494, December 2024.
Different populations of Aedes aegypti, consisting of lab‐established and recently collected African lines display similar diurnal activity patterns. Despite this consistent diurnal activity, variations in activity and sleep levels are observed among the populations, where differences among lines were more pronounced in the lab‐adapted populations ...

Common and distinct roles of juvenile hormone signaling genes in metamorphosis of holometabolous and hemimetabolous insects.

PLoS ONE, 2011
Insect larvae metamorphose to winged and reproductive adults either directly (hemimetaboly) or through an intermediary pupal stage (holometaboly). In either case juvenile hormone (JH) prevents metamorphosis until a larva has attained an appropriate phase

Biogenic amines in protocerebral A2 neurosecretory neurons of Lymantria dispar L. (Lepidoptera:Lymantriidae): Response to trophic stress [PDF]

, 2011
The number, morphometric parameters and amount of aminergic neurosecretory product of protocerebral A2 neurosecretory neurons were investigated in the fifth instar of Lymantria dispar caterpillars, following a suitable or unsuitable trophic regime ...

Commodity risk assessment of Cornus alba and Cornus sanguinea plants from the UK

EFSA Journal, Volume 22, Issue 3, March 2024.
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘high risk plants, plant products and other objects’. Taking into account the available scientific information, including the technical information provided by ...

MAPHIS—Measuring arthropod phenotypes using hierarchical image segmentations

Methods in Ecology and Evolution, Volume 15, Issue 1, Page 36-42, January 2024.
Abstract Animal phenotypic traits are utilised in a variety of studies. Often the traits are measured from images. The processing of a large number of images can be challenging; nevertheless, image analytical applications, based on neural networks, can be an effective tool in automatic trait collection.

Dietary cardenolides enhance growth and change the direction of the fecundity‐longevity trade‐off in milkweed bugs (Heteroptera: Lygaeinae)

Ecology and Evolution, 2021
Sequestration, that is, the accumulation of plant toxins into body tissues for defense, was predicted to incur physiological costs and may require resistance traits different from those of non‐sequestering insects.
