Q.1
Which of the following is/are the CORRECT options for management of red pumpkin beetle of cucurbits in organic farming?
(A). Early sowing of the crop
(B). Deep ploughing after the crop harvest.
(C). Follow clean cultivation
(D). Adopt grafting on bottle gourd
Choose the correct answer from the options given below:
- Organic Management of Red Pumpkin Beetle (Aulacophora foveicollis):
- Early Sowing: Sowing cucurbit seeds in November–December (under riverbed/polythene covers) or early February allows plants to advance beyond the vulnerable seedling stage before beetles emerge from winter hibernation.
- Deep Summer Ploughing: Exposes soil-inhabiting pupae and overwintering adult beetles to desiccation and predatory birds.
- Clean Cultivation: Eradicates alternative weed hosts and crop residues.
- Grafting on bottle gourd (D) is ineffective because bottle gourd (Lagenaria siceraria) is a favored host of Aulacophora.
- Correct Option: Option 2 ((A), (B) and (C) only).
