Pollinator diversity and influence of mode of pollination on yield of bottle gourd

DH Padhiyar and SR Patel
The present investigation was made on availability of pollinator fauna of bottle gourd and impact of mode of pollination on the fruit yield of bottle gourd. Bottle gourd flowers attracted a total of nine pollinator species, encompassing eight families and spanning five orders. Of all the insect visitors, lepidopterans (44.44%) were the most prevalent, with coleoptera coming in second at 22.22%. Hemiptera, orthoptera, and odonata each accounted for 11.11% of the insect visitors. Nesidiocoris spp. found as dominant flower visitors in bottle gourd with 37.65 percent contribution. It was followed by Haptones spp. (31.76%) and Aulacophora foveicollis (9.41%). The maximum activity (30 visits/m2/5 min) of flower visitors was found during the 18:00 hrs of the day while no any activity was observed during 06:00 to 07:00 hrs and 10:00 to 14:00 hrs of the day. The quantitative parameters of yield viz. the number of fruits/plant, percent fruit set, percent malformed fruit, fruit diameter, fruit weight, yield, and yield/ha were maximum in open pollination (5.38, 59.67%, 25.09%, 6.84 cm, 961.24 g, 5.17 kg/plant and 25,836 kg/ha, respectively) compared to pollination with Apis cerana indica (5.14, 54.03%, 20.43%, 6.76 cm, 878.57 g, 4.52 kg/plant and 22,607 kg/ha, respectively). No any fruit formation was observed in pollination without insects.
