Answer :

Final answer:

Signs of a potential pest infestation include observing pests such as house flies and cockroaches, and using pest resistant cultivars and natural predators for effective management. Observation of beneficial creatures like dragonflies is not a sign of pest infestation.

Explanation:

Signs of a possible pest infestation include observing pests such as house flies, termites, beetles, ants, cockroaches, and various other insects. Effective pest management often involves the use of pest resistant cultivars, strategic interplanting, and non-chemical control methods like the use of lamps and poplar twigs to trap adult pests. Rather than widespread spraying, targeted application of pesticides on the cotton plant's stem is used to protect beneficial species that provide natural pest control, such as birds and predatory insects. A sign that is not indicative of a pest infestation might be observing creatures like dragonflies or pollinators that are typically beneficial to the environment. Identifying pest infestations correctly is crucial for applying suitable management practices and preserving the ecological balance.
