The population ecology of Helicoverpa armigera in smallholder crops in Kenya with emphasis on its natural enemies. Final report, Phase I: April 1987-March 1988
The project completed a survey and selection of sites for population and mortality studies in Phase II: the field site for detailed studies is expected to be the Kenya Agricultural Research Institute (KARl) Station at Kakamega, while regular, less intensive, sampling programmes will be undertaken at KARl Stations at Kibos (near Kisumu), Msabaha and Embu. Four of the seven objectives of Phase l were met despite a very poor field season and administrative delays, these being a survey of information of natural enemies of H. armigera, surveys in Kenya and establishment of collaboration in other countries, initiation of taxonomic studies, and experimental sites selection. Two other objectives, natural enemy studies in Kenya and field sampling studies in Kenya were not met due to unforeseen circumstances, but compensatory work in the UK on existing data-sets allowed much progress to be made in this area.
