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

TL;DR: The keys to sustainable management of this pest include understanding linkages between the soybean aphid and other introduced and native species in a landscape context along with continued development of aphid-resistant varieties.

TL;DR: Insect and fungus feeding behaviour, affected tree part, and water stress severity are proposed as three important predictors of forest damage in drought conditions.

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: Results indicate that data obtained at a relatively constant water potential in a controlled environment can be used to approximate those values under the more variable conditions found in the field.
