The Answer is Two diseases that involve different arthropod vectors in their epidemiology are malaria and Lyme disease.

Malaria is a disease caused by the Plasmodium parasite and is transmitted to humans through the bite of an infected female Anopheles mosquito. The role of the mosquito vector in the life cycle of the parasite is crucial for the transmission of the disease. When an infected mosquito bites a human, it injects the parasite into the bloodstream. The parasite then travels to the liver where it matures and reproduces, eventually re-entering the bloodstream and infecting red blood cells. The mosquito becomes infected when it bites an infected human and ingests the parasite, which then goes through a series of developmental stages in the mosquito before it can be transmitted to another human through a subsequent bite.

Lyme disease, on the other hand, is caused by the bacterium Borrelia burgdorferi and is transmitted to humans through the bite of infected black-legged ticks, also known as deer ticks. The role of the tick vector in the life cycle of the bacterium is essential for the transmission of the disease. When an infected tick bites a human, it transfers the bacterium into the bloodstream. The bacterium then spreads to different parts of the body, causing the symptoms of Lyme disease. Ticks become infected with the bacterium when they feed on infected animals, such as mice or deer, and then transmit the bacterium to humans during subsequent feedings.

In both cases, the arthropod vector plays a crucial role in the transmission and establishment of the disease. Understanding the life cycle of the pathogen and the role of the vector is essential for developing effective control and prevention strategies for these diseases.
