  • This pest causes a lot of damage in  sponge gourd  crops in both the stages of its life cycle i.e. nymph and adult.

  • They suck the cell sap out of  sponge gourd plant leaves and inhibit plant growth. These insects are also the cause for the secretion known as a sooty mold developed on the plant.

  •  Sponge gourd can get completely infected during high infestation and even if the crop is fully developed, there is a chance of infestation of this pest which can cause the leaves of this crop to dry up and fall.

  • For the prevention of this pest, Diafenthiuron 50% SP @ 250 gram/acre or Flonicamid 50% WG @ 60 ml/acre or acetampyrid 20% SP @ 100 gram/acre or Pyriproxyfen 10% + biphenanthrene 10% EC 250 ml/acre.

  • This also results in distorted and malformed.
  • The maggots feed on the pulp of fruits as well as on the immature seeds and cause premature dropping of fruits.

Control:-

  • Collected and destroy infected fruits.
  • To prevent egg laying fly traps (Pheromons traps) can be set up in the yield with 1%methyl Engenol or Cintronella oil or vinegar or dextrose or Acetic acid or laetic acid.
  • Cover developing fruits with paper or polythene cover immediately after anthesis pollination.
  • Maize plants grown in rows at a distance of 8-10 cm in sponge gourd field is effective as flies rest on such tall plants.
  • Soil incorporation of cabaryl 10% dust can be made in fruit fly endemic areas.
  • Spraying of Dichlorovas @3ml/lit of water at fortnightly intervals.
  • Deep ploughing to expose hibernating stages.
