Halloween genes in panarthropods and the evolution of the early moulting pathway in Ecdysozoa [PDF]
Royal Society Open Science, 2018 Moulting is a characteristic feature of Ecdysozoa—the clade of moulting animals that includes the hyperdiverse arthropods and less speciose groups, such as onychophorans, tardigrades and nematodes.

New insights on the effects of spinosad on the development of Helicoverpa armigera
Ecotoxicology and Environmental Safety, 2021 Helicoverpa armigera (cotton bollworm) is one of the most destructive pests worldwide. Due to resistance to Bacillus thuringiensis and conventional insecticides, an effective management strategy to control this pest is urgently needed.

New Cytotoxic Steroid from Stachyurus imalaicus var. himalaicus
Molecules, 2007 A phytochemical study of the ethanolic extract of Stachyurus imalaicus var. himalaicus was undertaken and as a result a new polyoxygenated steroid, named stachsterol ((20S)-20, 25-dihydroxy-4-cholesten-3-one, 1) and three known ecdysteroids, 20 ...

Autophagy studies in Bombyx mori [PDF]
Invertebrate Survival Journal, 2015 Autophagy, which is well conserved from yeast to mammals, plays essential roles in development and diseases. Using the domesticated silkworm, Bombyx mori, as a model insect, several reports on autophagy have been made recently.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum
Insect Science, EarlyView.RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.
