Occurrence of Lasioderma serricorne (Coleoptera: Anobiidae) in rice grains from the city of Rio Branco, state of Acre, Brazil

ABSTRACT

Lasioderma serricorne (Coleoptera: Anobiidae) is an important pest in the food and tobacco industry in many regions of the world. A species of polyphagic behavior, despite being a pest capable of successfully breeding and developing in a complex variety of products based on grains, spices and animal by-products, there are few occurrences of this species in the northern region of Brazil. This study was carried out to report the occurrence of L. serricorne in rice grains in the city of Rio Branco, in the state of Acre. In June 2020, the presence of developing L. serricorne was observed in rice grain mass. Identification was performed at the species level using available dichotomous keys. As it is the first record of L. serricorne in rice grains in the city of Rio Branco, the monitoring of insects in the mass of rice grains is necessary for investigation in the search for methods for the management of stored grain pests.
