Artificial trap nesting of bees will help in their conservation in situ and utilizing them for enhancing pollination service in cropping systems. The present study was undertaken to study the nesting behavior and rate of acceptance of pithy stems for nesting by the different bee species at ICAR-NBAIR Yelahanka Campus (13.096792N, 77.565976E). Fifteen nests comprising of pithy stems of Caesalpinia pulcherrima each made into three bundles containing five nests each were placed at three places in two sites viz., Site 1 (Pollinator Garden) and Site 2 (Vegetable block). The days taken by the bees to accept the trap nests placed in the pollinator garden and vegetable field were found to be 5.87 and 11.53 days with a percent acceptance of 80 and 66.67 per cent, respectively. The average number of cells built by the bees in the nests obtained from the pollinator garden and vegetable ecosystem were found to be 6.00 and 5.33 respectively. Ceratina binghami, C. hieroglyphica, Megachile lerma and predatory sphecid wasps were found to emerge out from the trap nests. Diversity of the stem nesting bees was found to be higher in the nests placed in the pollinator garden as compared to vegetable block.Keywords

Bees are the primary pollinators of many important agricultural crops. Enhancing the suitability of farm landscapes for native pollinators by growing flowering non crop plants is necessary for in-situ conservation of bee pollinators. A study has been conducted to find the role of four different plants, viz., Hamelia patens, Ocimum basilicum, Asystesia sp. and Jacquemontia sp. in the conservation of native bee pollinators. The different species of bees visiting the flowers were Apis cerana, A. florea, Hoplonomia sp., Amegilla zonata, A. confusa and Ceratina hieroglyphica. The diversity indices were higher during morning hours than the afternoon. The number of bees visited per flower, time spent and numbers of flowers visited on Jacquemontia sp. were more compared to other plant species. Biodiversity indices were calculated by using Insect Biodiversity Analysis Portal, which is an online tool to carry out biodiversity analysis and hosted at https://www.nbair.res.in/Biodiversity. The planting of bee-friendly plant species as identified in this study will help support healthy, diverse pollinator and other beneficial insect communities.Keywords
