PEREZ TORRES, Betzabeth Cecilia et al. Entomofaunistic study in of the cultivation of amaranth (Amaranthus hypochondriacus L.) in Puebla Mexico. Rev. Mex. Cienc. Agríc [online]. 2011, vol.2, n.3, pp.359-371. ISSN 2007-0934.

Amaranth is a very important crop for the agricultural producers association around the Popocatepetl, Puebla, for its high nutrients content and for the preparation of various enriched food products. But losses from damage caused by insect pests, make not satisfactory yields for farmers. The aim of this study was to taxonomically determinate the amaranth cultivation related insects and to describe each species role in the agrosystem. To catch insects during the 2008 agricultural cycle, surveys were conducted at three plots where collections were made with vacuum, netting and manually; looking at the stems, knots, between knots, leaves (beam and back), panicle and roots. The larval stage organisms collected were preserved in 70% alcohol, while adults were mounted on entomological pins, all the material was identified and deposited in the entomological collection of the Institute of Sciences of the Autonomous University of Puebla (BUAP). Obtaining 1 883 morphospecies out of which 20 genera and 18 species were identified as the most abundant during the crop cycle, the next eight species were the cause of crop damage: Sphenarium purpurascens, Epicauta cinerea, Spodoptera exigua, Pholisora catullus, Ligys lineolaris, Herpetogramma bipunctalis, Amauromyza abnormalis and Phyllophaga ilhuicaminai.
