Occurrences of insect pests and natural enemies on rice plants in Uganda, East Africa

Abstract

We investigated the occurrence of insect pests and natural enemies on rice plants and weeds around rice fields in Uganda, East Africa, during 2010 and 2013. The following pest arthropods were collected with an insect net: large-sized stalk-eyed fly (Diopsis longicornis), small-sized stalk-eyed fly (D. apicalis), plant bugs (Pentatomidae and Alydidae), planthoppers and leafhoppers (Delphacidae and Cicadellidae), leaf beetles (Chaetocnema spp., Chrysispa viridicyanea and Altica spp.), short-horned grasshoppers (Coryphosima spp. etc.) and long-horned grasshoppers (Tettigoniidae). Small-sized natural enemies, such as parasitic wasps (Hymenoptera: Eulophidae, Cynipoidea, Braconidae and Ichneumonidae), were also captured.
