Mango fruit borer<br />
Citripestis eutraphera (Family Pyralidae)<br />
Description:<br />
Eggs: Newly laid eggs are white <strong>and</strong> turn red after 1 day. Size: 1 mm<br />
in diameter.<br />
Immatures: Newly hatched larvae are pale pink with a dark brown to<br />
black head. Young larvae are pale pink-brown in colour with 4 b<strong>and</strong>s<br />
<strong>of</strong> black spots that run along the body. As the larvae become mature<br />
they darken to red brown. Size: up to 15 mm in length.<br />
Adults: The forewings are dark brown <strong>and</strong> the hindwings are pale<br />
white-grey with a grey b<strong>and</strong> around the margin. Size: Wing span:<br />
female 24 mm, male 20 mm.<br />
Life Cycle: Eggs take 2–3 days to hatch. Once hatched, the larvae<br />
take 14 days to mature <strong>and</strong> pupate. After 14 days, the adult emerges.<br />
In captivity, adults live for up to 10 days.<br />
Similar to: Other moths, particularly those in the family Pyralidae.<br />
Damage: Eggs are laid on the skin around the stem end <strong>of</strong> the fruit or<br />
on the skin within the top third <strong>of</strong> the fruit. If two fruit are hanging on the<br />
tree <strong>and</strong> touching, eggs are sometimes laid on the skin surface where<br />
the two fruit make contact. Wet looking frass is seen on the outside<br />
<strong>of</strong> the fruit. After hatching, the larvae will initially feed by chewing the<br />
surface <strong>of</strong> the skin <strong>of</strong> the fruit <strong>and</strong> then tunnel into the flesh.<br />
Monitoring: Inspect immature <strong>and</strong> mature fruit on the trees as well as<br />
fallen fruit for holes with frass.<br />
