Anatomy of a Neotropical insect radiation
BackgroundMuch evolutionary theory predicts that diversity arises via both adaptive radiation (diversification driven by selection against niche-overlap within communities) and divergence of geographically isolated populations. We focus on tropical fruit

Different insect species exhibit remarkable diversity in the developmental trajectories from fertilized eggs to hatching larvae. For three myrmicine ant species, we observe a novel combination of a developmental features: small embryonic primordia, a mode of embryogenesis termed short/intermediate germ‐band development, and progressive establishment of

Land‐use intensification is filtering for species, able to cope with anthropogenic landscapes. This was assumed to result in functionally and phylogenetically homogenous communities, but a recent meta‐analysis could not confirm a consistent homogenization response to human pressure and raises open questions.

Proteolytic stabilization of a spider venom peptide results in an orally active bioinsecticide
Selective editing out of an insect gut protease cleavage site renders a spider‐derived insecticidal peptide active by ingestion by insect pests. Abstract BACKGROUND The toxin peptide U1‐AGTX‐Ta1b from the Hobo spider, Eratigena agrestis (Walckenaer, 1802), was studied to determine its potential to serve as a bioinsecticide.

This study reveals strong variability in the effects of eight tomato integrated pest management‐compatible pesticides on Dolichogenidea gelechiidivoris, identifying harmful compounds such as spinosad and more selective ones such as sulfur and spiromesifen, depending on the exposure route.

Serial cross sections (80 nm) and an image stack (353 sections) of the head of the extremely miniaturized first instar larvae of Stylops ovinae (Stylopidae) were obtained with serial block-face scanning electron microscopy. This approach made it possible

Ergonomic Evaluation of a Walk‐Behind AI‐Based Cotton Fertilizer Applicator
ABSTRACT The mechanization of agricultural operations greatly influences both the efficiency of farming operations and the health and safety of farm workers. Human exposure to working environments represents a significant hazard associated with machines and the environment.

We investigated the developmental toxicity of a new graphene‐based fluorescent nanoprobe for tumor cell nucleus (GTTNs) using Oryzias melastigma embryos. The results confirmed that GTTNs have excellent biocompatibility for biomedical applications. Only the highest dose delayed hatching time.

Understanding how species survive at their poleward limits of distribution is of interest in species conservation, particularly in light of global warming and predictions of shifting distributions of both predators and prey species. How species adapt to high latitudes and to future climate changes will be impacted both by direct interactions with the ...
