What type of insect can spread diseases like West Nile virus in Arkansas?

The mosquito is the correct answer because it is the primary vector for several diseases, including the West Nile virus. Mosquitoes transmit the virus to humans and animals when they feed on blood, which allows them to carry pathogens from one host to another. In Arkansas, as well as in many other regions, certain species of mosquitoes are particularly adept at spreading this virus, especially in areas close to standing water, which serves as breeding grounds for these insects.

The other insects mentioned do not have a significant role in transmitting the West Nile virus. Flies, dung beetles, and other types of beetles do not typically act as vectors for this virus and are not known to spread such diseases in a manner similar to mosquitoes. Understanding the specific role mosquitoes play in disease transmission is essential for implementing effective public health measures to control outbreaks, especially in areas where such viruses are prevalent.
