The term African Pest refers to two different species of insects: the TSETSE (6 letters) and the Tsetsefly (9 letters). The TSETSE is a large fly found in tropical and subtropical regions of Africa, while the Tsetsefly is a species of blood-sucking fly that is also found in Africa. Both species are considered pests due to their ability to transmit diseases such as sleeping sickness and nagana. They are also known to feed on livestock, which can cause significant economic losses.
