In Stephanie Pain’s article on the perils posed to coffee crops by climate change, the problem was clearly stated and some of the possible solutions discussed (5 January, p 32).
However, to control the coffee berry borer that was mentioned and a similar damaging pest – the white stem borer – the best hope is genetic transformation of the coffee plants with genes that code for anti-insect proteins.
Needs must if the devil drives the tune, and insect pests are the very devil, especially in tropical and sub-tropical areas.
