Responses of Adult Hypera rumicis L. to Synthetic Plant Volatile Blends

open access: yesMolecules, 2022
The behavioral responses of Hypera rumicis L. adults to varying blends of synthetic plant volatiles (SPVs) at various concentrations in lieu of single compounds are reported for the first time. For this study, Rumex confertus plants were treated with two

Curculionidae

open access: yes, 2007
Curculionidae With about 4 600 genera and 51 0 0 0 described species, the family Curculionidae is an order of magnitude larger than any other in weevils and comprises in excess of 80% of all weevil species. Its stupendous species richness is a principal factor in the large size of the Phytophaga and in fact of all Coleoptera, thus in Haldane’s ...

Behaviour and metabolism during tonic immobility (death-feigning) in Eucryptorrhynchus scrobiculatus and E. brandti (Coleoptera: Curculionidae)

open access: yesEuropean Journal of Entomology, 2021
The antipredator behaviour, tonic immobility (TI) is a valuable defence that enables insects to increase their chance of survival and is a trade-off between fleeing and protection.

Advances in research on autophagy in the maintenance of insect–microbe symbiosis

open access: yesNew Plant Protection, EarlyView.
Autophagy plays a dual regulatory role in insect–microbe symbiotic relationships. Beneficial symbiotic bacteria in insects participate in nutrient exchange via the TOR pathway, whereas pathogenic microbes induce immune defense through the AMPK pathway. Autophagy‐related genes regulate development and pathogen clearance during this process.

Rainforest conversion to monoculture plantations restructures functional communities of braconid parasitoid wasps

open access: yesOikos, EarlyView.
The conversion of rainforests into rubber and oil palm plantations drives biodiversity loss in Southeast Asia. Parasitoid wasps are highly diverse and play an essential role in ecosystems by regulating herbivore populations. Declines in density and diversity of parasitoid wasps, after land‐use change is well‐documented, but potential functional losses ...
