Capsid Pests of Cacao in Nigeria

Extract
The Capsid bugs, Sahlbergella singularis, Hagl., S. theobroma, Dist., and Helopeltis bergrothi, Reut., have been recognised as pests of cacao in the Gold Coast for more than 30 years7,8. Whilst there has never been any divergence of opinion as to the major status of Sahlbergella as pests of cacao, this does not appear to be true of Helopeltis. Patterson (see various reports of the Gold Coast Department of Agriculture,17, 18, 19, 20) considered Helopeltis to be a major pest and indicated that damage to shoots, as well as to pods, is frequent; whereas Cotterell3 describes H. bergrothi as a minor pest of cacao and states that “damage to herbaceous shoots is of very rare occurrence.” In 1939 Cotterell6 reported that he had found another Capsid (? Bryocaropsis sp.) to be comparatively widespread on cacao around Tafo.
