Interpretive Summary:

Technical Abstract: A burrower bug, pangaeus bilineatus (Say) (Heteroptera: Cydnidae), is known to feed extensively on peanut kernels, Arachis hypogaea L., particularly under certain reduced tillage production conditions. Levels of burrower bug kernel feeding (0, 5, 10, 25, and 50% of kernels by weight) were tested for effects on peanut oil quality and peanut flavor. Burrower bug feeding was found to detrimentally affect peanut oil quality as measured by a decrease in oxidative stability and an increase in peroxide values. However, burrower bug feeding did not measurably affect fatty acid profile parameters or 16 flavor score criteria at the kernal-feeding levels tested. Our data indicate that incidental kernel feeding by this pest is not likely to be detrimental to peanut flavor. Therefore, management of p. bilineatus should focus on the threat of grade reduction and aflatoxin contamination that can occur at high feeding incidence levels under drought-stressed, reduced-tillage production conditions.
