Interpretive Summary: Sugarcane aphids cause economic damage to sorghum production in Oklahoma. Although insecticides when applied in a timely manner provide efficient control, it is hard to protect against unexpected heavy infestations. This article evaluates the effect of weather on sugarcane infestation. Models identified a north-westerly wind direction to cause persistent aphid movements. The increase in spring wind speed also had a positive effect on the average distance that sugarcane aphids could travel. Results serve as a base for sugarcane aphid infestation predictions and to assist production planning for Oklahoma sorghum producers. “USDA is an equal opportunity provider and employer”.
Technical Abstract: Sugarcane aphids have caused economic damage on sorghum and other grain production in Oklahoma. When applied in a timely manner, insecticides provide efficient control; however, it is difficult to protect against the unexpected heavy infestations that have appeared frequently since 2016. This article evaluates the effect of spatial and temporal patterns of weather variables on sugarcane infestation airborne movements. Econometric methods identified persistent northwesterly wind patterns that explain aphid movements. Results serve as a base for sugarcane aphid infestation predictions and to assist stakeholders in developing an early warning system for sorghum producers. “USDA is an equal opportunity provider and employer”.
