ABSTRACT
In this paper, we provide taxonomic updates on the genus Leptagrion Selys: the females of L. acutum Santos and L. porrectum Selys are illustrated and diagnosed for the first time. We also add to the original description of L. acutum based on a male collected in the Atlantic Forest. A key for females is also provided for the currently known species of Southeast of Brazil.

We observed the viability of extruded starch products used as impact protector for fragile packing as a food source of the following stored grains pests: Cryptolestes ferrugineus (Stephens), Lasioderma serricorne (Fabr.), Oryzaephilus surinamensis (L.), Sitophilus oryzae (L.), Tribolium castaneum (Herbst) (Coleoptera) and Plodia interpunctella (Hübner) (Lepidoptera). Cryptolestes ferrugineus, L. serricorne and T. castaneum were found in these products, which are used by them as shelter and food. Under experimentation, we observed the development of O. surinamensis, S. oryzae and P. interpunctella feeding on this food source. Thus, it is recorded the viability of such material to be a potential dispersal vehicle to spread insect pests.

Observou-se a viabilidade dos produtos à base de amido extrusado, que são usados como protetores de embalagens frágeis, como recurso alimentar para espécies-praga de grãos armazenados: Cryptolestes ferrugineus (Stephens), Lasioderma serricorne (Fabr.), Oryzaephilus surinamensis (L.), Sitophilus oryzae (L.), Tribolium castaneum (Herbst) (Coleoptera) e Plodia interpunctella (Hübner) (Lepidoptera). Cryptolestes ferrugineus, L. serricorne e T. castaneum foram encontrados nesses produtos, usando-os como alimento e abrigo. Sob experimentação, O. surinamensis, S. oryzae e P. interpunctella se desenvolveram, alimentando-se também desse recurso. Desta forma, registra-se a viabilidade dos flocos de amido extrusado como potencial veículo disseminador de pragas.
