What stage causes damage for the Colorado potato beetle?

Larva only
Adult only
Pupa only
Both larva and adult

The correct answer is: Both larva and adult

The Colorado potato beetle causes damage during both its larval and adult stages. The larvae are known for their voracious appetite, feeding on the leaves of potato and other solanaceous plants. This feeding can lead to significant defoliation, weakening the plant and reducing its yield. Adult beetles also contribute to the damage by feeding on the foliage. Their feeding habits can have a cumulative effect, leading to severe harm to the plants they infest. Understanding the life cycle of the Colorado potato beetle is essential for effective pest management. Both life stages play crucial roles in their impact on crops, which is why recognizing that damage can arise from larvae and adults is important for those involved in pest prevention and plant regulation. This comprehensive view aids in implementing control measures that can target both stages effectively.
