1995 The effect of different amounts of sucrose (0, 250, 500, 750, 1000 (control), 1250, 1500, 1750 and 2000
mg/ml diet) on various parameters of the reproductive potential was studied. In absence of sucrose the flies
died within 3 days and for adults of B. cucurbitae the optimal dietary level of sucrose is 66.67 per (dry wt.) for
optimum longevity, total oviposition and egg viability.
1995 The effects of dietary water, sucrose and yeast hydrolysate on oviposition and longevity were studied by
eliminating each component one at a time. Water was essential for the survival of adults, which died if kept
without water for more than 24h. Without sucrose, adults died within 3 days. When adults were kept on a diet
without protein, females failed to oviposit, although adults lived longer (113 days) than those fed on a diet
containing all components (101.6) days.
1995 The effects of minerals on the reproductive potential of B. cucurbitae was studied. In the absence of minerals
from the diet, oviposition period, longevity, egg deposition, number of oviposition peaks and egg viability
were drastically reduced (by 34.00 days, 24.70 days, 2987.70 eggs (two-thirds), 4.33 peaks and 21.13%,
resp.), leading to a considerable reduction in the reproductive potential of the pest. Thus, minerals are
extremely important for normal reproduction of B. cucurbitae
1995 Three different artificial diets, yeast hydrolysate based, casein based and amino acid based, were evaluated
for their effects on various parameters of the reproductive potential . When all the parameters were assessed
together, the yeast hydrolysate based diet containing bulk nutrient was found to be most suitable as it
supported maximum reproductive potential. It was followed by the casein based and amino acid based diets.
1996 In two artificial oviposition receptacles (a paraffin dome and a plastic, lemon-shaped receptacle) for B.
cucurbitae tested for comparison with pumpkin fruits, average oviposition per 20 females per day was 2.80
and 17.20, respectively, compared with 150.20 in pumpkin fruits.
B. cucurbitae Lall and Singh 1969 In laboratory rearing, adults were kept in breeding cages with slices of cucumber; slices containing eggs
were removed to glass troughs containing a layer of sand and more cucumber, in which the larval stage was
passed; the pupae were transferred to petri dishes of moist sand to prevent desiccation, and the ensuing
adults were returned to the breeding cages. Under these conditions 9-10 generations were reared, each
lasting 12.56-33.61 days according to the time of year.
B. dorsalis Pant et al. 1990 The effect of the pH of artificial diet on the growth and development of B. dorsalis was studied under aseptic
conditions. The optimum pH was 5, with 87.5% of larvae developing to the pupal stage and a growth index of
3.88. Growth and development were adversely affected when the pH was below 4.5 or above 5.5.
