Features
- Named 'ash weevil' due to their grey, ash-like color. Also called grey weevils. Known for the characteristic notched edges they leave on leaves
- Adults are small, pear-shaped beetles with a distinct snout. Color is typically greyish-white or light brown. Have 11 black spots on their wing covers in some species
- Adults chew leaves starting from the edges, creating irregular 'V' or 'U' shaped notches. Larvae (grubs) live in soil and feed on roots
- Leaves show characteristic notched margins. Heavy feeding can lead to defoliation. Larval damage to roots can cause wilting and stunted growth
- Adults lay eggs in soil near roots. Grubs feed on roots for several weeks before pupating. Adults emerge and feed on foliage. Multiple generations per year
- Adults are small, typically 3-6 mm long. Tiny snouts are characteristic of the weevil family
- Most active during warm, humid months. Often seen in groups on host plants
- Attack a wide range of plants including cotton, maize, sorghum, pulses, guava, mango, and various ornamental trees
- Prevent by maintaining healthy plants and removing weeds that might harbor them. Monitor plants regularly for early signs of notched leaves
- Handpick adults if populations are small. Use neem oil or insecticidal soap. For serious infestations, soil drenching for larvae may be necessary
