There was a publication L38, in 1973 by the National Resources Institute, "A Preliminary Investigation of Field and Secco Infestation of Gambian Groundnuts by Caryedon serratus (01). It made very interesting reading, and proved the infestations were most manifest at the transit crossings near the Gambia River. They used Lindane as a pesticide, then Malathion, then finally a gas under plastic sheeting, but may have another method by now. The beetles become immune to the pesticide after about 10 years.
