Growing mustard with cabbage as a trap crop is used to attract which insect?

Correct option is A

· Correct answer: (a) Diamond Back moth
· Mustard is often used as a trap crop for the Diamond Back moth (Plutella xylostella), which is a major pest of cabbage. The trap crop attracts the moth, reducing damage to the main cabbage crop.
Other options:
· (b) Cabbage butterfly: While cabbage butterflies are pests, they are not as attracted to mustard as the Diamond Back moth.
· (c) Leaf Webber: Not primarily attracted to mustard as a trap crop.
· (d) Cabbage semilooper: A different pest, not primarily attracted to mustard.
