Step 1
Release of infertile flies - The number of flies in the next generation is decreased
Answer
Release of infertile flies is an effective control measure because it reduces the population of fruit flies over time. By introducing infertile flies into the environment, these flies compete for mates with fertile flies, resulting in fewer offspring. This, in turn, leads to a substantial decrease in the number of fruit flies in the following generation.
