When a pesticide is developed and tested, researchers want to make sure that beneficial insects are not harmed. For these insects, what do researchers quantify?

In the process of developing and testing pesticides, researchers quantify the impact of the pesticide on predatory insects, the effect of the pesticide on pollinators, and the impact of the pesticide on insect diversity.

Explanation:

When developing and testing a pesticide, researchers aim to ensure the pesticide is effective against harmful insects but does not harm beneficial insects. In order to achieve this, they quantify several factors related to these beneficial insects. The primary focus includes the impact of the pesticide on predatory insects that are known to naturally control pests by feeding on them. For example, it would be counterproductive to use a pesticide that harms ladybugs, which are natural predators to aphids, a common plant pest.

Researchers would also look at the effect of the pesticide on pollinators such as bees, butterflies, and other insects that play a crucial role in plant reproduction. Pesticides that negatively impact pollinators can lead to decreased plant propagation and fruit production.

In addition, they will study the impact of the pesticide on insect diversity. A diversified insect population often leads to a more stable and resilient ecosystem, which helps in pest control and overall ecological balance. Therefore, it's equally important to observe if a pesticide is causing a decline in insect diversity.
