| Abstract: | Abstract The present status of the imported and naturally occurring insects pests of Lantana camara L. a noxious exotic weed in Zambia, was determined by survey. Of the seven insect species imported in 1969–74, only Teleonemia scrupulosa Stål has become established in Zambia and occurs today all over the country. Two other neotropical lantana insects, namely Ophiomyia lantanae (Froggat) and Lantanophaga pusillidactyla Walk, have spread naturally into Zambia. In addition, 17 indigenous insect species were recorded as infesting lantana during the survey. The actual injuriousness of the insect complex to lantana was in all cases negligible, and it was concluded that insects will probably not contribute significantly to lantana control in Zambia. |
