Question: Leaf curl virus of chilli is transmitted by:
Options:
White fly
Aphid
Jassid
Honey bees
✅Explanation:
-Whiteflies are the primary vectors for transmitting the leaf curl virus in chili peppers. These tiny insects feed on the plant sap and, in the process, inject the virus into the plant tissues, leading to the characteristic leaf curling, stunted growth, and reduced yield.
🔑Key point-
1. Aphids
-Myzus persicae: Beet mosaic, Lettuce mosaic, Turnip mosaic, Potato virus
-Acrythosiphon pisum: Bean common mosaic, Bean yellow mosaic, Soybean mosaic, Pea enation mosaic
-Pentalonia nigronervosa: Bunchy top disease of Banana
-Toxoptera citricidus: Citrus tristeza
-Aphis gossypii: Papaya mosaic virus, Ring spot of papaya
2. Leaf hopper
-Circulifer tenellus: Beet curly top
-Agallia contricta: Potato yellow dwarf, Purple top (MLO disease)
-Mycoplasmal diseases: Little leaf of brinjal (transmitted by leafhopper)
3. Whitefly
-Bemesia tabaci: Okra yellow vein mosaic, Okra leaf curl, Chilli leaf curl, Cotton leaf curl, Papaya leaf
4. Thrips
-Thrips tabaci: Tomato spotted wilt virus
-Scirtothrips dorsalis: Chilli leaf curl
5. Mealy bug
-Planococcus sp.: Cocoa swollen shot
-Pseudococcus brevipes: Pineapple wilt, Papaya streak virus
6. Grasshopper
-Melanophus differetialis-potato virus x,tobacco mosaic virus
7. Lace bug
-Stephanites typicus: Root wilt of coconut (MLO disease)
8. Citrus psylla
-Diaphorina citri: Citrus greening
9. Leaf miner
-Phyllocnistis citrella: Citrus canker
10. Mites
-Acaria sp.: Fig mosaic
11. By fungus
-Cucumber mosaic virus, Tobacco necrosis virus, Peanut clump, Potato mop top, Potato virus X
