1992 A bait trap (0.5g Dipterex 80SP per 100g sweet gourd flesh), an insecticide spray (0.1% Dipterex 80SP +
100g molasses per litre of water ) offered stastically similar levels of control of the fruit fly attacking snake
gourd and kept the pest infestation within 4.9-8.6% as compared to 22.5% in the untreated control in
farmers field. The catches of fruit fly in bait traps were of 1.6 times more females than males.
B. cucurbitae Gourd Thrivandrum Pillai et al. 1991 Palayankodan banana fruit impregnated with carbofuran at the cut surface was found very effective in
trapping and can be used as a good tool for management systems at a lesser cost.

1997 Fenvalerate at 0.02% with 1% molasses was the best of 15 treatments tested against B. tau on ridge gourd (Luffa
acutangula). The plant products Multineem [a preparation from Azadirachta indica] and Polygonum hydropiper leaf
extract at different doses were less effective than fenvalerate, cypermethrin and malathion. Multineem, however,
proved to be superior to P. hydropiper in suppressing attack by the pest. The treatments with molasses were more
effective than those without molasses.
1991 In bait plantain fruit was found superior to jaggery, honey and molases.
2002 Efficiency of indigenous food baits for attracting the adults of B. cucurbitae infesting bitter gourd,
Momordica charantia, was assessed under field conditions. The bait containing pulp of overripe banana
(1kg) + Furadan [carbofuran] (10g) + citric acid (1g) was best in luring the fruit fly adults during peak
activity period of the pest. However, addition of sweet basil [Ocimum basilicum] leaf extract reduced the
attractiveness of the bait. The bait remained effective up to 10 days after installation in the field.
Singh et al. 1997 In trials of bait traps, mango juice (5%) was the most effective bait in reducing damage to fruits (36.6% in
physiologically mature and 17% in dropped fruits).

2001 The attractant-bait mixture containing boric acid-borax (3:1) as toxicant, protein hydrolysate (4%) as
attractant in water, when fed to five-day-old adults of fruit fly, B. tau, kept in rearing cages in the laboratory,
caused 40-98.3 per cent mortality after 24h of exposure with different concentrations (1-12%) of the
toxicant. The LC50 value was calculated to be 1.95. The bait mixture remained effective up to a week and
when sprayed on tomato plants caused phytotoxicity, above 2 per cent concentration of the toxicant, within
24h.
1977 50 g/l sugar was added to the insecticide sprays used for controlling fruit fly. Endosulfan and carbaryl were
the most effective insecticides.
