What is a common result of using Juvenile Hormone Analogs on immature insects?

1. Increased molting success

2. Sterility in adults

3. Development of larger body parts

4. Enhanced reproductive capacity

The correct answer is: Sterility in adults

Using Juvenile Hormone Analogs on immature insects typically leads to sterility in adults. Juvenile hormones play a crucial role in regulating development and reproduction in insects. When these hormones are present during the larval stages, they promote growth and prevent the insect from maturing into a fully reproductive adult. By introducing Juvenile Hormone Analogs, which mimic the effects of natural juvenile hormones, the progression to the adult stage can be disrupted or altered, ultimately causing the individuals to be sterile once they reach maturity. This characteristic is often exploited in pest management strategies to control insect populations. The other options relate to different effects that either do not occur with these analogs or are typically not observed as a direct result of their application.
