Question

Quizplus · Accepted Answer

Developing and marketing a new pesticide can be very expensive, and the potential sales in the United States may not be enough to offset the costs. Additionally, regulations and testing requirements for new pesticides have become increasingly strict, further driving up costs and creating a regulatory barrier to entry for new products. As a result, pesticide producers may be hesitant to invest in the development of new mosquito-killing insecticides, especially as existing insecticides continue to be effective in many areas.
