Extract

Sinoxylon senegalense is essentially the wood borer of felled Acacia seyal Del. in the Sudan, damage due to other beetles being contributory in a very small degree.

The life-history of the Bostrychid is recorded. The period from egg to adult is about eight weeks, but the complete life-cycle is considerably longer. The larval tunnels are superficial and only a few inches in length. The damage is almost entirely due to the adult, which remains boring within the logs for nearly 10 months. A predacious Clerid, Cylidrus fasciatus, and Braconid parasites, a species belonging to genus near Doryctes and Platyspathius pictipennis, were recorded.

Destruction of the timber is very rapid and control methods should be undertaken as soon after felling as possible. Insectaries were prepared containing the timber treated in various ways and the behaviour of the insect noted in each instance. The chemicals used in the experiments were sodium arsenite, boracic acid and pentachlorophenol. The latter, used as a spray on barked logs, was found to be the most effective.
