B. dorsalis Patel et al. 1996 Two experiments were conducted to identify the optimum dose of methyl eugenol required per trap to attract B.
dorsalis.
B. cucurbitae Bitter gourd Maharastra Pawar et al. 1991 Monitoring by using traps baited with the sex attractant tephrit lure. Result showed that cue-lure was a more
effective attractant than tephrit lure.

2000 Holy basil (Ocium sanctum, a known methyl eugenol source) is used in Kerala (20g of crushed leaves with 0.5g
each of citric acid and of cabofuran 3G in 100ml of water) at four traps/ha as bait.
Sarada et al. 2001 An experiment was conducted in a mango orchard to evaluate the different coloured plastic open pan traps viz.,
yellow, white, blue, orange, red and green as attractants for fruit flies such as B. dorsalis, B. correcta and B.
zonata in three replications at Tirupati, Andhra Pradesh, during 2000. During the same year another two
experiments were conducted with these open pan traps by placing them at different heights (0, 1.0, 1.5 and 2.0
metres) above the ground and at different locations in the orchard. An open pan of 60 cm diameter with 7.5 cm
depth, along with 0.1% methyl eugenol attractant was used for the purpose. Significantly more flies were attracted
to white (16.953 flies/trap) and yellow (15.317 flies/trap) coloured traps followed by green, orange, red and blue,
respectively. Lowest number of flies were attracted to blue colour. Traps placed on the ground caught significantly
most flies (12.433 flies/trap), followed by 1.0m, 2.0m and 1.5m, respectively. Traps in the periphery of the orchard
attracted more flies (945 flies) than traps in the centre (561 flies).
B. correcta Mango Southern Gujrat Shah and patel 1976 Tulsi plant (Ocimum sanctum) used as male attractant. Chemical analysis showed that 40% of the essential oil
content of this plant consisted of methyl eugenol.

Shah and Patel 1976 During studies in southern Gujarat in India on the extent and timing of attacks by B. correcta (Bez.) on mango,
this fruit-fly was found for the first time on an aromatic plant, Ocimum sanctum (tulsi plant), but only males were
attracted to it.
1985 Benzyl acetate is used to attract B. cucurbitae and B. dorsalis.
Singh and Seghal 2001 Five fractions from distilled A. calamus oil, obtained after column chromatography, were analysed. Fractions that
were attractive to B. cucurbitae and B. dorsalis, i.e. FI, FII and FV, were further purified and tested on flies, B.
dorsalis and B. cucurbitae, under laboratory conditions. All fractions were attractive to both flies. FI (beta-asarone)
was highly attractive to the males of B. dorsalis. FII (acoragermacrone) was attractive to female B. cucurbitae, but
was only slightly attractive to male flies of the same species. FV (unidentified) was attractive only to female B.
dorsalis. No fraction showed equal attractiveness to both sexes of either species or to the same sex of both
species.
