Advanced Science, EarlyView.We identify a Lepidoptera‐conserved testis‐specific arylalkylamine N‐acetyltransferase (LTNAT) that governs male moth fertility via a novel mechanism. LTNAT loss disrupts eupyrene sperm mitochondrial derivatives and impairs apyrene sperm motility, offering a safe molecular target for innovative pesticides and genetic pest control.

Ecology and evolution of pyrazines in insects
Biological Reviews, EarlyView.ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Identification of orb-web spider species and their food source through environmental DNA analysis
Journal of Ecology and EnvironmentSpiders play a vital role in agricultural ecosystems by capturing and preying on small insects, thereby controlling the pests around crops. However, without directly collecting the specimen, it is challenging to accurately determine the species of the ...

Extent and toxicity of contaminated marine sediments in Southeastern Florida [PDF]
, 2004 Thirty sites were sampled in southern Biscayne Bay and Manatee Bay in December 1999 to determine the extent of toxicity in sediments. Analyses and assays included: pesticides and phenols in seawater; chemical contaminants in sediment; amphipod mortality,

Developmental Dynamics, EarlyView.Abstract Background Jointed appendages represent one of the key innovations of arthropods, and thus understanding the development and evolution of these structures is important for the understanding of the evolutionary success of Arthropoda. In this paper, we analyze a cell cluster that was identified in a previous single‐cell sequencing (SCS ...
