A #1: This is a "decoy" for tsetse flies. It's shape and synthetic odour--delivered from bottles at its base-- simulate a large animal. It attracts host-seeking tsetse flies of the Glossina morsitans group. The flies land and contact a lethal insecticide dose; a highly effect, cheap, and simple control method.
A #2: The environment is a rice field. The vectors are Anopheles and Culex tritaeniorhynchus mosquitoes. The infections are malaria and various arboviruses, particularly Japanese Encephalitis.
A#3: The Environment is a tire dump. The vectors are (1) the Aedes aegpti mosquito, which transmits Yellow Fever in Africa and south America; and (2) The Aedes albopictus mosquito, which transmits Dengue in SE Asia. The Albopictus mosquito was apparently introduced into the US by a used tire shipment.
