Megaceresium horni (Heller), a new longicorn stem borer of cocoa in the British Solomon Islands
A new pest of cocoa in the Britihs Solomon Islands, Megaceresium horni Heller (Cerambycidae), is described. The larvae cause severe damage to branches by tunnelling through the pith and sapwood, one larva may kill up to 3 m of branch in 4-6 weeks. In the outbreak reported, up to 5 branches per tree were infested on 58 percent of the trees. An intensive campaign of pruning and burning infested branches at 3-4 days intervals for one month, followed by pruning at two weekly intervals for three months, reduced the level of infestation from over 100 larvae per 100 trees to 2 per 100.
