1) Young larvae feed on tender foliage.
2) Mature larvae bore circular holes
on fruits.
3) Thrust only a part of its body into
fruit and eat the inner content.
 Spherical eggs are yellowish
white colour when laid but
changes to dark brown as they
mature. Singly laid
 Diameter: 0.4mm to 0.6mm

 It has dark brown grey lines on the body with
lateral white lines and also has dark band.
 When the last larval instars are about to
become pupae, the larvae will burrow and
enter the soil to pupate.
 Pupae are 14-18mm length, brown smooth
surface and rounded anterior and posterior.
 Not all pupae will develop into adults
without pupal diapause.
 Pupal diapause varies and highly
dependent on temperature and
photoperiod.
 Female- Light pale brownish yellow snout moth.
 Male- Pale greenish moth V shaped speck.
 Forewing: olive green to pale brown with a dark brown circular spots in
the centre.
 Hindwind: pale smoky white with a broad blackish outer margin.
