TLDR
Both vote counting and meta-analysis found strong negative effects of water stress on the performance of sap-feeding insects at large and subguilds, respectively.Abstract:
Traditionally, herbivorous insects are thought to exhibit enhanced performance and outbreak dynamics on water-stressed host plants due to induced changes in plant physiology. Recent experimental studies, however, provide mixed support for this historical view. To test the plant-stress hypothesis (PSH), we employed two methods (the traditional vote-counting approach and meta-analysis) to assess published studies that investigated insect responses to experimentally induced water-deficit in plants. For insects, we examined how water deficit affects survivorship, fecundity, density, relative growth rate, and oviposition preference. Responses were analyzed by major feeding guild (sap-feeding insects and chewing insects) and for the subguilds of sap-feeders (phloem, mesophyll, and xylem feeders) and chewing insects (free-living chewers, borers, leaf miners, and gall-formers). Both vote counting and meta-analysis found strong negative effects of water stress on the performance of sap-feeding insects at large and...read more

Autumn, the neglected season in climate change research
TL;DR: Some of the existing understanding of autumn phenology is synthesized and five areas ripe for future climate change research are identified, to address common pitfalls in autumnal research and to support the conservation and management of vulnerable ecosystems and taxa.

Effects of drought and heat on forest insect populations in relation to the 2003 drought in Western Europe

TL;DR: In this paper, the impact of the secheresse and the canicule on the populations of infra-forestiers in Europe was investigated. But, the authors only focused on the effect of the stress hydrique on the performance of the infra -forestiers, i.e., their ability to adapt to changes in the environment.

TL;DR: Greenhouse dispersal experiments demonstrated that the potato leafhopper, Empoasca fabae (Harris), strongly preferred well-watered alfalfa, Medicago sativa L., over the moderate and severe water-stressed treatments.

TL;DR: The interactions among timing of stress, level of stress and host genotype, shown in this study to influence sawflv performance, demonstrate how different combinations of these factors may result in opposing conclusions concerning the effects of host plant stress on herbivore performance.
