CDFA Pest Prevention Plant Regulation Practice Exam

What is the significance of the cherry fruit fly in relation to agricultural pests?

1. It causes damage only in the egg stage

2. It has multiple generations per year

3. It can lead to extensive crop loss

4. It is harmless to most crops

The correct answer is: It can lead to extensive crop loss

The cherry fruit fly is significant in relation to agricultural pests primarily because it can lead to extensive crop loss. This pest affects cherry crops by laying its eggs in the fruit, which can result in damage as the larvae feed within the fruit itself. As they develop, the presence of these larvae can render the cherries unmarketable, causing economic loss to farmers and impacting the supply chain. Therefore, the ability of the cherry fruit fly to severely damage a crop is a critical aspect of its significance in agriculture, emphasizing why effective pest management strategies are essential for protecting fruit production and maintaining yields. The other options do not accurately capture the pest's implications on agriculture. For instance, although the pest may have multiple generations, which contributes to its prevalence, the primary concern is the resulting crop losses. Furthermore, it does not cause damage only in the egg stage, and it is certainly not harmless to most crops, as its feeding habits directly result in significant economic and agricultural impacts.
