FILLING THE GAP There is still no researched based, time

efficient, user-friendly sampling system of SCA that determines density and rapidly evaluates if the treatment threshold has been met. Necessary for early detection and effective

management of this aphid. Can include information on beneficials and

allow for sustainable multifaceted management approaches.

Smith, 2015

THE APPROACH Multi-state collaboration expanding the

work of Brewer et. al (2014) Oklahoma (Elliott, Giles, Zarrabi and Royer) Texas (Bowling and Knutson) Kansas (McCornack) Louisiana (Brown) Arkansas (Seiter)

Brewer et. al (2014)

THE APPROACH Characterize seasonal within field and

within plant distribution of SCA in sorghum. Develop sequential and binomial sampling

protocols for SCA in sorghum. Validate sampling protocol using natural

infestations. Use protocol to develop and deliver a

research-based, dynamic, user-friendly decision making tool for SCA management.
