These Caterpillars are very fussy. They are a world-wide pest, feeding only on the shoots and fruit of

  • Eggplants ( Solanum melongena, SOLANACEAE ).

    The caterpillars are white or pink, with four dark dashes on the prothorax, and with four small pale brown warts on the back of each abdominal segment. The head is brown.

    The caterpillar leaves its foodplant to pupate elsewhere in a brown cocoon.

    The adult moth is white with some yellow and some black markings, and a reddish-brown splodge near the middle of each forewing. The natural resting posture has the tail of the abdomen curled up and forwards. The male moth has a wingspan of about 1.5 cms. The female moth is larger with a wingspan of about 2 cms.

    The species has been found in

  • India,
  • Nederlands,
  • Pakistan,
  • Philippines,
  • Seychelles,
  • South Africa,

    as well as in Australia in

  • Queensland.

    Control of this pest has been tried with:

  • planting the crop under netting,
  • destruction of borer damaged fruits at regular intervals, and
  • use of Neem and other plant extracts,
  • use of various artificial insecticides,
  • mass trapping using the pheromones,
  • use of the bacterium Bacillus thuringiensis subsp. kurstaki,
  • combination of various microbial extracts,
  • use of the parasitic wasp Eriborus sinicus ( ICHNEUMONIDAE ), and
  • breeding resistant varieties of Eggplant by crossing with Solanum macrocarpon.
