CDFA Pest Prevention Plant Regulation Practice Exam

Which plants are primarily attacked by Colorado potato beetles?

1. Members of at least 3 or more plant families

2. Deciduous fruits

3. Certain plants of the solanum genus

4. Certain Ipomoea plants

The correct answer is: Certain plants of the solanum genus

The Colorado potato beetle is primarily known for its association with plants in the Solanum genus, most notably the potato and other related crops like tomatoes and eggplants. This beetle has evolved to specifically target these plants due to their nutritional content and preferred habitat, making them its primary hosts. The lifecycle, feeding habits, and reproductive behaviors of the Colorado potato beetle are closely linked to the species within the Solanum genus, which provide ideal conditions for their development. Understanding this relationship highlights the importance of monitoring and managing these particular plants in agricultural settings to prevent significant crop losses. The specificity of the Colorado potato beetle's preference reinforces its status as a serious pest in the cultivation of these crops.
