Which insect pest is known to infest St. Augustine grass?

1. Chinch bugs

2. Scale insects

3. Mealybugs

4. Spider mites

The correct answer is: Chinch bugs

Chinch bugs are a significant pest known to infest St. Augustine grass, primarily because they thrive in warm, humid conditions, which are typical for the environments where St. Augustine is commonly grown. These pests feed on the grass by sucking out the sap, which can lead to yellowing and the eventual death of patches of grass. Identifying and controlling chinch bugs is crucial for maintaining the health and appearance of St. Augustine lawns. Their presence can also cause stress for the grass, making it more susceptible to disease and other pests. Therefore, recognizing chinch bugs as a major threat is essential for effective lawn care and pest management strategies.
