Final answer:
Two overlooked facts in modern insect control programs include the potential negative impact of biological control agents on non-target species, and the underappreciated role of natural predators in controlling pest populations.
Step-by-step explanation:
The question asks about two critically important facts that are often overlooked in the design of modern insect control programs. The first overlooked fact is the negative impacts that some biological control agents can have on non-target species, even leading to unintended extinctions. While biological control can be cost-effective and reduce pesticide use, it is not always selective enough, and agents such as generalist predators might attack and suppress populations of native or non-pest species. The cactus moth and the rosy wolf snail are historical examples of biological controls that led to ecological upheaval.
The second overlooked fact is related to the complex ecological role of natural predators and how they contribute to pest management. A significant portion of pest control is actually performed by natural predators and parasites, but this aspect is under-studied and often not effectively incorporated into pest management strategies. Recognizing the economic value and ecological significance of promoting natural pest control agents and preserving their native habitats could enhance the effectiveness of insect control programs while protecting the environment.
