Pest Information

Spodoptera littoralis is one of the most destructive agricultural lepidopteran pests within its subtropical and tropical range in Africa and the Middle East. The host range covers more than 40 plant families, containing at least 87 species of economic importance. Spodoptera littoralis larvae prefer feeding on young leaves. They may also feed on young shoots, stalks, bolls, buds, and fruits, often gnawing holes which allow diseases to enter the plant tissue.

Fall armyworm (Spodoptera frugiperda) is a very destructive agricultural lepidopteran pests within its subtropical and tropical range in Africa and South America. Furthermore it is an important pest of grasslands in North America. The insect has invaded Africa in 2016 and has since spread throughout all of Sub-Sahara Africa, wreaking havoc wherever it showed up. The pest can feed on plants of many different species and families, and shows a preference for Poaceae, the sweetgrasses, to which belong many economically important species. When feeding on maize, eggs are often deposited within the whorl of young maize plants. The young larvae feed inside the whorl, so correct application timing and site of any plant protection product is very important.
