Tsetse flies are blood-feeding insects that primarily feed on the blood of vertebrate animals, including humans, livestock, and wildlife. They use their specialized mouthparts to pierce the skin of their host and feed on their blood. Tsetse flies are known to transmit diseases such as sleeping sickness in humans and nagana in livestock through their blood-feeding habits.

Feeding Habit of the Tsetse Fly (Glossina species)
Tsetse flies are blood-feeding insects belonging to the family Glossinidae. They are obligate parasites, which means they can only survive by feeding on the blood of mammals.
Target Hosts:
- Tsetse flies primarily target large mammals, such as cattle, horses, antelope, and humans.
- They can also feed on other vertebrates, including reptiles and birds.
Blood Feeding Process:
- Tsetse flies have specialized mouthparts called proboscises, which are adapted for piercing the skin of their hosts.
- When they land on a host, they extend their proboscis and insert it into the skin.
- They inject saliva into the wound, which contains anticoagulants and vasodilators to promote blood flow.
- They then suck up the host's blood using a muscular pump in their abdomen.
Feeding Frequency:
- Tsetse flies typically feed once every 2-3 days.
- They may take multiple blood meals from different hosts during their lifetime, which is typically several months to a year.
Host Selection:
- Tsetse flies are primarily attracted to the scent of their host's sweat and breath.
- They also use visual cues, such as movement and dark objects, to locate hosts.
- Certain species of tsetse flies are attracted to specific colors or patterns, such as blue or black, while others are not.
Impact of Feeding:
- Tsetse fly bites can be painful and itchy.
- They can transmit deadly diseases to humans and animals, such as sleeping sickness and animal trypanosomosis.
- The economic impact of tsetse-transmitted diseases can be significant in areas where the flies are prevalent.
