Toxic and Repellence Activities of Four Plant Extracts to Dermestes maculatus Degeer on Smoked African Mud Catfish, Clarias gariepinus Burchell

F.O. Akinwumi, E.A. Fasakin and C.O. Adedire

Abstract:
The efficacy of ethanol extracts of four tropical plant materials: pepper fruit, Dennettia tripetala Baker; clove, Eugenia aromatica Hook; African nut-meg, Monodora myristica (Dunal) and black pepper, Piper guineense (Schum and Thonn) was evaluated under tropical storage conditions for the control and repellence of the leather beetle, Dermestes maculatus. In separate experiments, adults and larvae of the pest were introduced to disinfested smoked Clarias gariepinus treated with plant extracts at 2.5, 5.0, 7.5 and 10.0%. Each of the four plant extracts evoked significant (p<0.05) mortalities in both adults and larvae of the fish beetle at all concentrations tested compared with the untreated (control) at 1, 3 and 7 days post-treatment. The extracts also exhibited repellency against D. maculatus. This study has revealed that the locally available botanicals could offer effective protection against post-harvest pests of fish and therefore could be incorporated into post-harvest fish management strategies.
