INVESTIGATION OF INSECT PESTS ON THREE SPECIES OF SMOKED FISH IN MUBI NORTH-EASTERN NIGERIA

Wahedi, J.A. & 2Kefas, M.

The research was carried out in Mubi, North Eastern Nigeria to investigate the insect pest species infesting three different species of fish, viz: Clarias spp, Tilapia spp and Synodontis spp. Dermestes spp, Necrobia spp and Tribolium spp were the common insect pests found infesting the three species of fish. Data collected on the total number of insect pests infesting each species of fish, as well as the distribution of the two life stages (larval and adult) of the insects was analyzed using simple percentage. The result showed that Tilapia spp was more prone to infestation by insect pests (57.3%) followed by Synodontis spp (24.4%) and then Clarias spp (18.3%) in the following order: Tilapia>Synodontis>Clarias. Tribolium spp was the dominant insect pest, with about 61.7% infestation on Tilapia spp, and 100% on Clarias spp, followed by Necrobia spp with 31% infestation on Tilapia spp and 80% on Synodontis spp. The distribution of adult and larval stages of the insect pests was also noted, and the result showed that the bulk of insects infesting the three species of smoked fish in Mubi, Nigeria, are in the adult stage.
