1973 Varieties of C. melo, which are highly susceptible to D. cucurbitae, had a higher number of aminoacids than
resistant, wild C. callosus. Cystine and tyrosine were present in C. melo but not in C. callosus, and histidine,
glycine, threonine and leucine were present in higher proportions in C. melo. It is concluded that antibiosis in C.
callosus may be due to low concentrations or imbalance of essential aminoacids.
1974 Laboratory studies were carried out on the resistance mechanism of antibiosis to B. cucurbitae Coq. in the wild
melon Cucumis callosus; the highly susceptible muskmelon cultivars Delta Gold and Smith Perfect, and the hybrid
C. callosus X Delta Gold were used for comparison. When reared on resistant fruit, larval survival, growth index,
pupal size and weight, the ratio of adult females to males, fecundity and adult life-span were lower, the larval period
was longer, and there was little effect on the pupal period.
1974 The highly susceptible C. melo variety Delta Gold and its hybrid with C. callosus were used in tests in the laboratory
to determine the resistance mechanism to B. cucurbitae in C. callosus. Variation in the number of eggs laid in the
different fruit types revealed that nonpreference for C. callosus resulted from the combined influence of a tough rind
and the biochemical properties of the fruit.
1974 Of 69 muskmelon accessions screened, 9 were resistant, 7 susceptible and the remainder highly susceptible to fruit
fly. The wild C. callosus, however, was highly resistant, and since it will hybridize with muskmelon it is likely to be of
value in breeding.
Choubey et al. 2002 An experiment was conducted in Jabalpur, Madhya Pradesh, India during the 1991 summer season to evaluate the
varietal response of watermelon cultivars MHW-11, Arka Jyoti, MHW-4, MHWHM-101, MHW-6, MHW-5, and
Madhu, against melon fruit fly (B. cucurbitae). Arka Jyoti was the least susceptible (38.81%) under Jabalpur
conditions.
Mango Dan et al. 1989 The hybrids Totapuri X Alphonso (T X A) and Totapuri X Mulgoa (T X M) gave larger fruits with smaller stones than
their parents. Hybrid T X A had a high fibre content, which made it suitable only for juice production, but was more
susceptible to fruit fly than its parents. Quality of juice was rated in the order Alphonso > T X A > T X M > Totapuri >
Mulgoa. Both hybrids had lower sugar:acid ratios than their parents. The hybrid Banganpalli X Alphonso was
suitable for canned slice production and was rated as superior to Banganpalli and only slightly inferior to Alphonso,
which has smaller fruits with larger stones than the hybrid.
