To determine life history parameters of the sugarcane aphid including the optimum, lower and upper thresholds for development.
The sugarcane aphid, Melanaphis sacchari (Zetner), was known to be in Florida and Louisiana in the 1970's, but in 2013 quickly spread to grain sorghum, forage sorghum and Johnsongrass, causing millions of dollars loss in agricultural production. What are lacking in knowledge for this devastating aphid is the temperature thresholds for growth on the stated host plants. In other words, what are the temperature and day length parameters that would allow such an aphid to have the growth potential to develop into such devastating populations? The USDA-ARS in Stillwater has answered this question for many different invasive aphid species, and in cooperation with OSU Entomology, can determine these temperature dependant growth parameters with student driven scientific study and the use of environmental growth chambers that are designed for such determinations.
