Abstract
The ecology of 3 spp. of Oxycarenus, a heteropteran insect, was studied in southern Ghana. Host plants are listed. Seasonal population changes were followed in O. fieberi and O. hyalinipennis, both of which frequent malvaceous host plants that flower throughout the year. O. dudgeoni showed successional colonization of host plants since its hosts include trees which have restricted flowering seasons. In all 3 spp., cotton (Gossypium hirsutum: Malvaceae) was either preferred or enjoyed equal preference with principal feral host plants. The natural enemies [assassin bugs, spiders, mites] of Oxycarenus and the defense mechanisms against them are described.
