Abstract: Quantitative spoilage effects of insects infestation on three processed shrimp species; Parapenaeopsis atlantica, Parapenaeus longirostris and Macrobrachium macrobrachion, collected from Oba�s market in Akure metropolis were evaluated. Fresh oven-dried specimens were weighed and distributed into three groups, each group with three replicates. Adult and larvae of Dermestes maculatus, Laeloglyphus sp. and Necrobia rufipes were collected from spoilt dried shrimp samples obtained from the same market. D. maculates was introduced (two insect adults and four larvae) into the containers containing the freshly-dried shrimps in triplicate and the last container was used as control in each group. Level of insect damage was evaluated on weekly basis for eight weeks. Weight of samples decreased as from the fourth week from the initial mean weight of 15g to 13.63g�1.15, 13.65�1.36 and 14.21�1.08 for P. longirostris, P. atlantica and M. macrobrachion, respectively. On the eighth week, some of the specimens were totally damaged by the insects. The effects of insect activities were very low in P. longirostris with a longer shelf life than other shrimp during storage.
