Occurrence of Clover Stem Borer, <I>Languria mozardi</I> (Coleoptera: Languriidae), on Canola: A New Host Record
Abstract
The clover stem borer (CSB), Languria mozardi Latreille (Coleoptera: Languriidae) at various life stages (larva, pupa and adult), was discovered on canola (Brassica napus L.; Brassicaceae) during the 2000-01 growing season; these plantings were part of the canola nursery at Alabama A&M University's Winfred Thomas Agricultural Research Station (WTARS) located in northern Alabama. This was the first and, so far, the only record of L. mozardi on canola. Given the wide range of host plants on which CSB has been reported to occur, this North American endemic species may pose a potential threat to canola production in the United States. Although our data showed differential preference for canola cultivars by CSB, damage by this species on canola was negligible. A comprehensive list of plant hosts of L. mozardi is also presented in this report.View this article in BioOne
