Which of these best explains why the apple farmers are seeing these new stronger bugs?

Why are the apple farmers seeing these new, stronger bugs? Changes in the weather have led to stronger insects that can survive these harsh changes. The strongest bugs were able to survive pesticides, reproduce and create more resistant pests.

Why is resistance to pesticides likely to occur over time when they are used in agriculture?

When a pesticide is first used, a small proportion of the pest population may survive exposure to the material due to their distinct genetic makeup. These individuals pass along the genes for resistance to the next generation. Some plant pathogens have also become resistant to pesticides.

What are specific ways insects have been found to develop resistance to pesticides?

Upon exposure to insecticides, insects that do not carry the resistance genes die, thus allowing the individuals with the resistance genes to survive and reproduce, creating more resistant insects. With every generation the number of resistant insects increase.

What are some of the long term effects of pesticides on human health?

Pesticides and human health: Examples of known chronic effects are cancers, birth defects, reproductive harm, neurological and developmental toxicity, immunotoxicity, and disruption of the endocrine system.

What happens if you don’t use pesticides?

Without it, our crops are forced to compete with weeds and are destroyed by pests. Without crop protection, green bean yields would fall 50 to 80 percent. And pesticides even protect chocolate from pests like mirids than can dramatically shrink cocoa yields.

What are the drawbacks of using pesticides?

On the other hand, the disadvantages to widespread pesticide use are significant. They include domestic animal contaminations and deaths, loss of natural antagonists to pests, pesticide resistance, Honeybee and pollination decline, losses to adjacent crops, fishery and bird losses, and contamination of groundwater.
