CDFA Pest Prevention Plant Regulation Practice Exam

How would you describe the flight ability of the adult European corn borer?

1. Crawling Insect

2. Weak Flier

3. Strong Flier

4. Wingless

The correct answer is: Strong Flier

The adult European corn borer is characterized as a strong flier. This classification is based on its physical adaptations, which include well-developed wings that enable efficient flight. Strong flying capacity allows these moths to travel considerable distances in search of mates and suitable habitats, which is crucial for their reproduction and dispersal. This capability helps increase their chances of finding food sources and escaping potential threats. The European corn borer's ability to fly effectively also contributes to its status as a significant agricultural pest, as it can easily spread from one crop to another, leading to widespread infestations in corn and other host plants. Other options, such as describing the insect as wingless or a crawling insect, do not accurately reflect its true biological characteristics, as adult European corn borers possess wings and are not limited to ground movement.
