Damage:
· This pest does not get eradication by insecticide application and causes 50-70% crops damage.
· The damage to crops caused by oviposition in fruit and soft tissues of vegetative parts feeding by the larvae.
· Decomposition of plant tissue by invading secondary microorganisms and fruit become distorted and drop down.
· Matured larvae/maggot transforms into pupae within couple of weeks and finally turns into adult fruit fly and again starts infestation.
Infestation Inception: After fruit formation.
Best time for Lure and Trap Installation: During fruit formation stage.
Application rate:
· 1 lure and 1 trap for 2.5 decimal land
· Trap to trap distance 10-12 meters as square form.
Pheromone lure and trap installation:
· Triangular windows should keep at the North-South direction.
· Whole trap should be hung at same height of plant just similar to its fruit keeping the prescribed distance.
· 1.5 inch distance should be maintained between bottom surfaces of trap to hang the block middle point of two triangular windows.
Precaution:
· If lure soaked by rain it might lose its effectiveness.
· Do not use chemical pesticide when pheromone trap already installed. Using of chemical pesticide destroys its effectiveness.
