Ecdysis in a stem-group euarthropod from the early Cambrian of China
Moulting is a fundamental component of the ecdysozoan life cycle, but the fossil record of this strategy is susceptible to preservation biases, making evidence of ecdysis in soft-bodied organisms extremely rare. Here, we report an exceptional specimen of

The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

Effects of age, density, and seasonality on molt pattern in the mammal genus (Peromyscus) [PDF]
Molting, or replacement of pelage (hair) in mammals, occurs during ontogeny as individuals transition from juveniles to adults. Environmental factors can cause variation in molt in many species for thermoregulatory and camouflage purposes.

Calcitonin‐like diuretic hormone influences reproduction in adult female Rhodnius prolixus
Highlights • CT/DH‐like immunoreactivity is present in female reproductive tissues • CT/DH receptor transcripts are expressed in the fat body and ovaries • RNAi knockdown of CT/DH receptors reduces egg number and hatching rate • Rhopr‐CT/DH increases RhoprVg1 and RhoprVgR expression in ovaries in vitro • Rhopr‐CT/DH stimulates oviduct contractions in a

Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...
