Abstract:

An experiment on the insect pollinators was conducted with four summer squash hybrids viz., Parikrama, Chandra, Chamatkar and Gold Queen at the Research Farm of the Department of Entomology, CCS Haryana Agricultural University, Hisar. Based on pollination index (loose pollen grains sticking on the body x abundance x foraging rate), A. mellifera was the most efficient pollinator of C. pepo with pollination index of 1177360 followed by A. dorsata (773280 ) and A. cerana (223420) and A. florea with pollination index 63480 under agro-ecological conditions of Hisar (Haryana). The abundance (bees/m2/5 minutes) of A. mellifera (2.21) was highest followed by A. cerana (1.16), A. dorsata (1.07) and A. florea (0.62). Irrespective of species, the population was maximum (1.45 bees/m2/5 minutes) at 1000-1200 h of the day. Foragers of A. dorsata, A. mellifera, A. florea and A. cerana commenced their pollen collection activity at 0600, 0630, 0700 and 0700 h, with peak periods at 0600-0800, 0800-1000, 1000-1200 and 0800-1000 h respectively and all of them ceased their activity between 1700- 1800 h.
