What is the primary component that attracts Argentine ants?

The primary component that attracts Argentine ants is sugary substances. Argentine ants are known for their preference for sweet foods, which is a significant part of their diet. They are particularly drawn to sugary secretions produced by aphids and other sap-sucking insects, as well as honeydew from these insects. This attraction to sugar helps Argentine ants to form large colonies and facilitates their foraging behavior, allowing them to gather food sources quickly and efficiently.

In contrast, while other options like meat, starches, and vegetables may be consumed by ants in general, they do not have the same strong appeal for Argentine ants specifically. Argentine ants have adapted to thrive in environments where they can access sweet substances, making sugary substances the correct answer regarding what attracts them the most.
