Abstract
Appropriate post-harvest management strategies are critical in sustainable fish production in the tropics. One of such approaches is the control of insect pest infestation, which is a major factor for the economic loss of smoked fishery products in the tropics. The use of synthesized insecticides is hampered by high cost of purchase, health concerns and right application. In this study, the efficacies of the powders of four locally available and inexpensive plant materials, namely: Dennettia tripetala Baker, Eugenia aromatica Hook, Monodora myristica (Dunal) and Piper guineense (Schum and Thonn) at 2.5, 5.0, 7.5 and 10.0 g/100 g smoked Clarias gariepinus Burchell were evaluated for the control of the dermestid beetle, Dermestes maculatus. Each of the four plant powders caused significantly high (P<0.05) mortality in both the adults and larvae of the fish beetle at all concentrations when compared to the control and was effective in inhibiting progeny development in the treated fish. The four plant materials could play a major role in protecting one of the commercially important fish species in the tropics and thereby prevent smoked fish losses, improve income generation, enhance the health and socio-economic status of fish consumers and processors.
