Sorry, I suggest here following traps for Bactrocera zonata on cucurbits. find it if useful.
•Use attractants like citronella oil, eucalyptus oil, vinegar (acetic acid), dextrose and lactic acid to trap flies.
•Use poison baiting in severe infestation: Saturated sugar solution 5 ml+ malathion 50 EC 5 ml+100 ml of fermented palm juice. Keep the bait in earthen lids placed at various corners of the field.
•Use fly trap: Keep 5 g of wet fishmeal in polythene bags (20 x 15cm) with six holes (3 mm dia), two cm from the bottom of the bag. Add a drop (0.1 ml) of dichlorvos in cotton plug and keep it inside the bag. Dichlorvos should be added every week and fishmeal renewed once in 20 days. (ca 20 traps/acre).
What about yeast baiting. We have used this in Tonga for attracting females Bactrocera spp. for quarantine control. You could bait traps with this. Here is the reference with recipe:

Sandeep, more references, we also tested in papaya orchard but I don't think that was published. We sprayed underside of every 15th tree. I remember it was very successful in the capsicum. There is quite a bit of information on FF Management in the SPC South Pacific Regional Fruit Fly Project pages. It has been a while but the principles are still valid.

Dr. Sandeep, I guess you can contact Dr Katina Lindhout at the CRC for National Plant Biosecurity, University of Canberra (Australia). She's working on Fruit fly trapping with special emphasis on female trappings. [email protected]
