| dc.description.abstract | Insect pollinators diversity with special reference to role of attractants in insect pollination for increasing the productivity of Bottle gourd (Lagenaria siceraria L.) was carried out during 2012 at Division of Horticulture, University of Agricultural sciences, GKVK, Bangalore. Ten species of insect pollinators were recorded during flowering before application of attractants. Whereas nineteen species of insect pollinators were recorded during flowering after application of Citral-a and Citral-b. Among them, eight species were belong to order Hymenoptera, five species to Diptera, three species to Lepidoptera and two species to Coleoptera and one species from Hemiptera. The abundance of A. dorsata was constituted 23.28 per cent, whereas other pollinators were constituted 76.70 per cent. The quantity of nectar and sugar concentration was more in female flowers (43.70 μl and 48.60 %) than in male flowers (28.60 μl and 27.40 %). Open pollination with Citral-a and Citral-b was attracting more number of pollinators up to third day of spraying particularly dipterans. After The role of attractant in pollination on quantitative and qualitative parameters such as fruit set, fruit weight, fruit volume, fruit length, number of sound seeds, test weight, moisture, ash content, TSS and germination percentage were maximum in open pollinated plot with Citral-a. However, there was no fruit set in control may be due to absence of insect pollinators. | en_US |
