TL;DR: Ability to overwinter on living annual and perennial hosts in southern sorghum-producing areas and wind-aided movement of alate aphids appear to be the main factors in its impressive geographic spread in North America.

TL;DR: They were generally responsive to changes in aphid density of both susceptible and resistant hybrids, but variability points to need for further study.

TL;DR: Without site-specific knowledge of a slow-growing aphid population and given cost and market price variability of the system, a 40 aphid per leaf threshold is most prudent to use across the range of hybrid, environmental, and market conditions experienced in this study.

TL;DR: Binomial sequential sampling plans for M. sacchari were developed that allow users to quickly classify the economic status of field populations and determine when an economic threshold has been exceeded, and can be adopted to easily and rapidly determine when M.sacchari infestations need to be treated.
