Herbivore prevalence poorly predicts yield in diverse cropping systems
Our study shows that the design and characteristics of cropping systems should be considered when assessing insect herbivory effects on crop yield. As herbivorous insects have a smaller impact on yield in diverse cropping systems, crop diversification may synergize biodiversity conservation and food production. Abstract Industrialized agriculture needs

Abstract Spring oilseed rape is severely affected by early season herbivory of various flea beetle species. Flea beetle pest management strategies with less reliance on conventional chemical insecticides are direly needed. However, the current knowledge of flea beetle ecologies and life cycles is insufficient to design and inform such strategies ...

BAS: Beetle Antennae Search Algorithm for Optimization Problems [PDF]
Meta-heuristic algorithms have become very popular because of powerful performance on the optimization problem. A new algorithm called beetle antennae search algorithm (BAS) is proposed in the paper inspired by the searching behavior of longhorn beetles.

Edible Jumpers Powered by Shell Snapping
This work demonstrates an entirely edible, centimeter‐scale jumper by instantly releasing elastic energy through shell snapping. It can jump up to 36 cm, comparable to previous non‐edible jumpers. Moreover, this jumper can be loaded with an edible latch to trigger the jumping upon humidity stimulus autonomously.

The cryptonephridial/rectal complex: an evolutionary adaptation for water and ion conservation
ABSTRACT Arthropods have integrated digestive and renal systems, which function to acquire and maintain homeostatically the substances they require for survival. The cryptonephridial complex (CNC) is an evolutionary novelty in which the renal organs and gut have been dramatically reorganised. Parts of the renal or Malpighian tubules (MpTs) form a close
