Abstract
Abstract Field experiments on the influence of intercropping sorghum ( Sorghum bicolor [L.] Moench), maize ( Zea mays L.), and cowpea ( Vigna unguiculata [L.] Walp.) on insect pests were carried out from 1983 to 1985 at Mbita Research Station of the International Centre of Insect Physiology and Ecology (ICIPE) on the shores of Lake Victoria, South Nyanza, Kenya. During that period the shoot‐fly ( Atherigona soccata Rond.), various stem borers ( Chilo partellus Swinhoe, Busseola fusca Fuller, Eldana saccharina Wlk., and Sesamia calamistis Hmps.) appeared on their appropriate host plants. In cowpeas thrips ( Megalurothrips sjostedti Trybom, Hydatothrips adolfifriederici Karny) and aphids ( Aphis craccivora Koch) caused severe damage. Reduction in stem borer population was achieved by intercropping cereals with cowpea. Significant differences in thrips population on cowpea influorescences were counted: 2950 adults/100 buds in pure cowpea and 1701 adults/100 buds in a sorghum/cowpea/maize intercrop. Zusammenfassung Zum Einfluß von Sorghum/Mais/Kundebohne‐Mischanbau auf die Schadinsektensituation in Mbita, Kenia An der Versuchsstation Mbita des International Centre of Insect Physiology and Ecology (ICIPE) am Viktoriasee, Süd‐Nyanza/Kenia, wurden 1983–1985 Untersuchungen zum Einfluß von Sorghum ( Sorghum bicolor [L.] Moench), Mais ( Zea mays L.) und Kundebohnen ( Vigna unguiculata [L.] Walp.) im Mischanbau auf Schädlinge durchgeführt. Während dieser Zeit traten an Sorghum die Schößlingsfliege ( Atherigona soccata Rond.) und an beiden Getreidearten verschiedene Stengelbohrer ( Chilo partellus Swinhoe, Busseola fusca Fuller, Eldana saccharina Wlk. und Sesamia calamistis Hmps.) auf. An Kundebohnen verursachten Thripse ( Megalurothrips sjostedti Trybom, Hydatothrips adolfifriederici Karny) und Blattläuse ( Aphis craccivora Koch) starke Schäden. Eine deutliche Reduktion der Stengelbohrerpopulation wurde durch den Mischanbau von Getreide und Kundebohnen erreicht. Signifikante Unterschiede ergaben sich in der Thripspopulation an Kundebohnenblüten: 2950 Adulte/100 Knospen wurden in den Reinsaaten und 1701 Adulte/100 Knospen in den Mischkulturen aus Sorghum/Kundebohnen/Mais ausgezählt.
