Visual Cues Are Relevant in Behavioral Control Measures for Cosmopolites sordidus (Coleoptera: Curculionidae) [PDF]

Journal of Economic Entomology, 2011
Trap designs for banana root borer, Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae), have been done essentially on the understanding that C. sordidus rely primarily on chemical cues. Our present results indicate that these borers also rely on visual cues.
