Insect pests of sweet orange (Citrus sinensis Osbeck) in some Ibadan market stores


ABSTRACT: Insect pests of sweet orange (Citrus sinensis) were surveyed from selected citrus fruit stores in Ibadan between February and September 1982. The
dipterans, especially the Drosophilidae, were the most numerous insect group collected in the survey, representing 70 per cent of the total number of insects collected in each survey. Two beetles, Carpophilus hemipterus and Carpophilus dimidiatus, constituted 20 per cent of each sample of insects while 10 per cent comprised other insect groups. This study also found that pest abundance needs be monitored, possibly
with the aid of the modified “steiner trap”.
