TL;DR: The ET developed here is strongly supported through soybean growth stage R5, which provides a 7-d lead time before aphid populations are expected to exceed the economic injury level (EIL) and exposes a larger portion of the soybean aphid population to selection by insecticides, which could lead to development of insecticide resistance.
Journal ArticleDOI
Demography of Soybean Aphid (Homoptera: Aphididae) at Summer Temperatures
TL;DR: The optimal temperature for soybean aphid growth and reproduction on soybean under controlled conditions was determined, using a modification of the nonlinear Logan model, to be 34.9 and 27.8°C.
Journal ArticleDOI
Management Recommendations for Soybean Aphid (Hemiptera: Aphididae) in the United States
TL;DR: A summary of integrated pest management tactics for soybean aphid are discussed, including cultural, genetic, economic, and chemical controls, which will reduce overall production costs and minimize negative environmental effects such as human exposure, and mortality of beneficial insects and other animals.

A Simple Method for In-Field Sex Determination of the Multicolored Asian Lady Beetle Harmonia axyridis
TL;DR: Labrum pigmentation is a more desirable character to use to determine sex, because it is more accurate and easily accessible, and should be used for in-field sex determination of H. axyridis.
