Question

The cassava is an important food crop for people living in sub-Saharan Africa. In the 1970s, mealybug infestations destroyed harvests and people starved. A researcher who studied the mealybug in its native environment discovered a parasitoid wasp that was a natural predator. After extensive testing to determine safety, the parasitoid wasp was introduced into the sub-Saharan region with tremendous effect controlling the mealybug throughout most of Africa. This approach represented a form of

natural enemies control.

genetic control.

natural chemical control.

cultural control.

ANSWER IS :
natural enemies control.

EXPLANATION:

Mealybug is a pest, called as destructive insect that attacks cassava which is an important food crop.

Now researcher found natural predator which is parasitoid wasp who kills or eats mealybug.

After extensive testing to determine safety, the parasitoid wasp was introduced to control the mealybug.

This approach represented a form of natural enemies control. Natural enemies control are organisms that decrease the reproductive potential or reduce the numbers of another organism.

Natural enemies control the pests by their natural enemies such as in question given, mealybug growth control by parasitoid wasp because mealybug destroy cassava.

Hope this answer is clear to you...
