Effects of Four Vegetable Oils on the Life cycle of Dermestes maculatus, Degeer, reared on dry fish (Clarias sp.)

The mortality of adult D. maculatus on fish treated with palm oil, groundnut oil, coconut oil and palm kernel oil at 2.5ml / kg, 5.0ml / kg and 10.0 ml kg respectively was monitored over a 15 day period. The highest mortality of 40% was recorded in groundnut oil, palm kernel oil and coconut oil at 10ml / kg treatment respectively at the end of the period. Lowest mortalities of 3.3% were recorded in the palm oil groundnut and coconut oil treatments at 2.5 ml/kg and 5.0 ml/kg respectively.
