Frankliniella fusca (Hinds 1902) - (tobacco thrips)
This thrips is found in North America and in parts of Central America and the Caribbean. It has been also reported from outside the Americas like from Japan. F. fusca is polyphagous and attacks a variety of crops. For example, it can cause serious economic damage to groundnuts, cotton and tomatoes. Further it is an important vector of the Tomato spotted wilt virus, which it transmits to groundnuts and other crops.
The thrips feed on flower and foliage. On ground nuts, it can be particularly destructive on young plants, where the feeding damage can result in stunting, delayed maturity, yield loss, and even plant death.
