Abstract
The efficacy of Piper guineense fruit oil in protecting dried fish against Dermestes maculatus (Degeer) infestation was investigated in the laboratory. Piper fruit oil extract were applied at dosages of 0.075ml/25g, 0.10ml/25g, 0.125ml/25g and 0.150ml/25g as protectant of dried fish (Clarias spp) against D. maculatus. Piper fruit oil at dosages of 0.125ml/25g fish and 0.150ml/25g fish were found to be efficient in the control of the development of D. maculatus adults and larvae stages on tested dried fish and was therefore recommended as appropriate dosage for prevention of insect infestation on dried fish. Keywords: Dried fish, Piper guineense, protectant, Dermestes maculatus. (Global Journal of Pure and Applied Sciences: 2002 8(2): 197-202)
