plant-insect-interactions
Plant-insect interactions encompass the dynamic ecological and biochemical relationships between plants and insects, including herbivory, pollination, and mutualistic associations. These interactions have profoundly shaped plant evolution, driving the development of chemical defenses, physical barriers, and floral traits that attract beneficial insects while deterring pests. Understanding these relationships is central to plant biology, informing research on plant immunity, reproductive success, and ecosystem-level processes.

A field experiment found that climate warming can soften the damage that gall-forming insects cause to tall goldenrod, but drought makes things worse — galled plants under dry conditions were least likely to reproduce successfully.
Galled plants were 7.1 cm shorter than non-galled plants under normal conditions, but warming eliminated this height reduction entirely.
Galled plants experiencing drought had the lowest seed production probability (0.47), lower than any other treatment combination.
Drought and warming interact with insect galling in opposite ways — warming buffered galling damage while drought amplified it.
