Antifeedant Mechanism of Dodonaea viscosa Saponin A Isolated from the Seeds of Dodonaea viscosa
Molecules, 2022 Dodonaea viscosa is a medicinal plant which has been used to treat various diseases in humans. However, the anti-insect activity of extracts from D. viscosa has not been evaluated. Here, we found that the total saponins from D.

Impact of Environmental Microparticles on Insect Olfaction
Environmental Toxicology, EarlyView.ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Robust olfactory responses in the absence of odorant binding proteins
eLife, 2019 Odorant binding proteins (Obps) are expressed at extremely high levels in the antennae of insects, and have long been believed essential for carrying hydrophobic odorants to odor receptors.

Insect Science, EarlyView.In this study, we examined whether realistic ozone concentrations can interfere with sexual communication in the insect pest Plutella xylostella, the diamondback moth. Ozone exposure caused a degradation of pheromone components, leading to significant changes in blend composition and component ratios.

Organization and function of Drosophila odorant binding proteins
eLife, 2016 Odorant binding proteins (Obps) are remarkable in their number, diversity, and abundance, yet their role in olfactory coding remains unclear. They are widely believed to be required for transporting hydrophobic odorants through an aqueous lymph to ...

Cladistics, EarlyView.Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

Larval character evolution in Holometabola (Insecta)
Cladistics, EarlyView.Abstract Larvae, a novel type of immature stage, are a crucial innovation of the Holometabola. Larval features therefore provide key evidence for reconstructing evolutionary transformations in this megadiverse group. Here we present the first formal reconstruction of larval character evolution, using maximum parsimony and Bayesian ancestral‐state ...
