Q.120
Given below are two statements
Statement (I) : Chaffer beetles feed on the leaves of roses and inflict large irregular cuts on the foliage
Statement (II) : Leaf cutting bees inflict neat circular or oval cuts on leaves and do not actually feed on leaves but use them
for lining of their mud nest
In light of the above statements, choose the most appropriate answer from the options given below.
EXPLANATION
Rose and Carnation Production Technology
- Statement (I) is True: Chafer beetles (Adoretus spp., family Scarabaeidae) are nocturnal pests that swarm rose plants at dusk, chewing voraciously on leaf blades, creating large, ragged, irregular holes and skeletonizing foliage.
- Statement (II) is True: Leaf-cutting bees (Megachile spp., family Megachilidae) use their sharp mandibles to slice out neat, smooth, circular or oval discs from rose leaf margins. They do not ingest the plant tissue for nutrition; instead, they carry these green cutouts to line, partition, and seal individual larval brood chambers inside their nesting burrows.
- Conclusion: Both Statement (I) and Statement (II) are true (Option 1).
Correct option: (1) Both Statement (I) and Statement (II) are true.
