Abstract

Many species of flea beetles (Halticinae) are known to be injurious to cultivated crops, particularly in the adult stage when they may cause severe damage to the foliage and growing points. So far, little damage to roots or leaves has been ascribed to the larvae. Two species, Podagrica uniforma Jacoby and P. sjostedti Jacoby, occur widely in Nigeria on most of the cultivated Malvales. Their damage gives a characteristic appearance of leaves riddled with holes, and they are commonly regarded as pests, although no specific recommendation has been made for their control. Donelly (1966) listed the 2 species as the first 2 in the order of numerical importance among the pest species recorded on kenaf, Hibiscus cannabinus. Two other species, P. dilecta Dalman and P. spadicea Dalman, also have been recorded, but these do not appear to occur in such large numbers and never appear to reach pest proportions on any of their hosts. Neither P. uniforma nor P. sjostedti is restricted to malvaceous or fiber crops, and the species have been recorded on legumes, grasses, cucurbits, etc., in Nigeria.
