ARELLANO, Germán; VERGARA, Clorinda  and  BELLO, Segundo. Insect pests and other pineapple (Ananas comosus var. comosus (L.) Merr., Coppens & Leal) crop arthropods in Chanchamayo and Satipo, Department of Junin, Peru. Ecol. apl. [online]. 2015, vol.14, n.2, pp.175-189. ISSN 1726-2216.

This study was focused in the determination of entomological pests in pineapple plantations in the rainforests of the Department of Junín, Peru. Based on assessments carried out from 1983 to1987, species determinations were updated and recent information was incorporated. The evaluation was based on regular monthly insects collects in pineapple plantations and in the herbaceous vegetation in the plantations, recording abundance, importance, damage, alternate hosts and natural enemies over these years. The specimens collected in the field and recovered in the laboratory were sent to the "Klaus Raven Büller" Entomology Museum of the Universidad Nacional Agraria, La Molina, for mounting and identification. The results of this work confirmed that the "pineapple fly" Melanoloma viatrix Hendel, which attacks the fruit, was the most serious entomological problem. Mites that live in floral cavities and insects associated with the inflorescence could be vectors and disseminators of Fusarium moniliforme and Penicillium foniculosum that cause "black spots on the fruit." In this paper the "pineapple fruit borer" Strymon megarus (Goardt) and the "pineapple mealybug" Dysmicoccus brevipes (Cockerell) were considered as potential problems
