This document provides an overview of the lesser grain borer, Rhyzopertha dominica, a serious pest of stored grains and cereal products. It describes the beetle’s appearance, habits, and biology, including its ability to infest a wide range of products. The article emphasizes the importance of inspection and sanitation in preventing infestations and outlines control measures, including the use of pheromone traps, insect-proof containers, and various pesticides. It also highlights the need for fumigation in cases of large infestations and provides a table of available pesticides for effective management. Publication date: March 1994.

Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae) is among most damaging stored rice pests in the United States. Infestations can occur within industrial grain bins, markets, or home pantries. While feeding on stored grains, adults bore holes into the kernels. Larvae can crawl inside a kernel through these holes, then cause further damage to the kernels by feeding on both the endosperm and the germ. This loss of grain can result in devastating economic impacts and lead to secondary issues such as the growth of fungi, further compromising grain quality and safety. Effective management strategies are crucial to mitigate these impacts.
