Doharey 1985 Preference of B. dorsalis on fruits of mango, guava and sapota [Manilkara achras] and of D. cucurbitae on pumpkin,
bitter gourd (Momordica charantia) and squash gourd (Citrullus vulgaris var. fistulosus) was studied, D. dorsalis
preferred mango, followed by guava and sapota and D. cucurbitae preferred bitter gourd.
Jujube Faroda 1996 The ber [Ziziphus mauritiana] cultivar Seb was crossed with a local cultivar, Tikadi, resistant to fruit fly (Carpomyia
vesuviana) in order to develop a pest resistant cultivar. The F1, although 90% resistant, had poor fruit quality. By
backcrossing to Seb, a BC1 line with 87-90% resistance and desirable fruit characters was obtained. A mean of
13% fruit fly infestation was observed in this line, along with a high level of antibiosis. Fruits weighed around 16 g
(4.5 g in the F1) and Brix value was 24°.

New Delhi Garg et al. 1979 Comparative suitability of tinda (squash melon) and pumpkin as larval diet for the development of melon fly (B.c.)
has been carried out with regard to oviposition preference and larval development. No preference between the 2
fruits was shown by ovipositing females, but the rates of pupation and adult emergence, together with the pupal
weights of larvae reared on them, indicated that tinda was more favourable to growth and development.

1987 Damage to peaches by the tephritid B. zonatus was studied in Punjab. The cultivar Sharbati, which is considered to
be suitable for the plains of northern India, was highly susceptible to attack by D. zonatus. Up to 89.50% of fruit was
damaged by B. zonatus.
1995 The tephritid B. cucurbitae, when reared on 3 cucurbit food plants, namely bitter gourd (Momordica charantia),
cucumber and sponge gourd (Luffa sp.), showed slight variations in the duration of the egg (1.1-1.8 days) and pupal
(7.7-9.4 days) stages, but it varied notably in the larval stage, being 6 days on Luffa sp. and 3 days on the 2 other
hosts. The highest mortality occurred during the egg stage (maximum 20%) on Luffa sp.
1995 The tephritid B. cucurbitae, when reared on 3 cucurbit food plants, namely bitter gourd (Momordica charantia),
cucumber and sponge gourd (Luffa sp.), showedthe shortest mean generation time (T = 25.8 days) and highest net
reproductive rate (Ro = 55.8) had the highest intrinsic rate of increase (0.16) on cucumber.
1995 The tephritid Bactrocera cucurbitae, when reared on 3 cucurbit food plants - bitter gourd (Momordica charantia),
cucumber and sponge gourd (Luffa sp.) - showed slight variations in the duration of the egg (1.1-1.8 days) and
pupal (7.7-9.4 days) stages, but it varied notably in the larval stage, being 6 days on Luffa sp. and 3 days on the 2
other hosts.
