Which of the following biotic factors are usually used to control cassava mealbugs?

Parasites and predators are biotic factors that are usually used to control cassava mealbugs. Parasites are organisms that live in or on a host organism and rely on the host for survival while causing harm to the host. Parasites of cassava mealbugs can be introduced into the environment to control their population. Predators are organisms that hunt and kill other organisms for food, and can also be introduced into the environment to control cassava mealbug populations. Pests, on the other hand, are organisms that cause harm to crops and are not used to control cassava mealbugs. Pathogens are disease-causing microorganisms and are also not used to control cassava mealbugs.
