Drought and up-and-down temperatures are affecting insect behavior – everything from honeybee behavior to delayed emergence of pests, according to a Texas A&M AgriLife Extension Service entomologist. “Prolonged drought, and these cold snaps we’re seeing do have impacts on the food web, and that impacts bees swarming and delayed emergence of some pests such as pecan nut casebearer,” said Charles Allen, AgriLife Extension entomologist and integrated pest management coordinator, San Angelo. Honeybee swarming is not uncommon, Allen said. Bees swarm – migrate en masse – when there’s not enough plant growth and nectar supply in an area to support a colony.
