Weather Influences Insect Pest Abundance

Abstract

This publication examines how local weather patterns—particularly temperature, moisture, and wind—influence insect pest development, behavior, and abundance in desert vegetable cropping systems. It highlights how extreme conditions such as heat, cold, rainfall, and wind can either promote or suppress pest populations. Specific examples include the impact of temperature on whiteflies, aphids, and diamondback moths, the role of rain and humidity in insect mortality, and wind-driven pest dispersal into Arizona crop fields. These insights help explain seasonal trends and aid in forecasting pest outbreaks.
