Abstract:

Chilo partellus Swinhoe (Lepidoptera: Crambidae) is an exotic cereal stem borer that was accidentally introduced into Africa from South Eastern Asia early 20th century. It is now widespread in most of the lowland areas of the Eeastern and Southern parts of the African continent. The invasive stem borer C. partellus, has proved to be a highly competitive colonizer in many of the areas it has invaded in eastern and southern Africa, often becoming the most serious stem borer.
