Pest Control Technician Practice Exam

Beneficial insects are vital to pest management because they contribute to maintaining ecological balance by preying on pest species. This natural form of control helps regulate pest populations, reducing the need for chemical interventions. For instance, predators like ladybugs feed on aphids, and parasitic wasps lay their eggs in or on pest species, effectively managing their numbers.

In contrast, while competing for resources can influence pest populations (as suggested in another choice), it does not have the same direct impact on pest control as predation does. The notion that beneficial insects primarily feed on crops misrepresents their role; rather, their feeding behaviors often focus on other insects. Additionally, being attracted to chemical pesticides is not a characteristic of beneficial insects aimed at pest management, as their effects are generally considered harmful to beneficial species. Overall, the preying behavior of beneficial insects is a crucial aspect of integrated pest management strategies.
