The visiting of four species of honey bees viz., Apis dorsata, Apis florea, Apis cerana indica and Apis mellifera were recorded on mustard [Brassica juncea (L.) Czernj. & Cosson] crop. The observation on visiting of honey bees showed that the neem product Achook was found to have least repellent effect on honey bees due to their higher visits i.e. 3.05, 4.40, 4.42, 6.35 and 6.70 per three minutes per m2 area just after, 24, 48, 72 hours and 5 days of insecticides application, followed by Bioneem i.e. 2.10, 3.15, 3.71, 5.70, and 6.37 visits, respectively. The Nimbicidine also provided 1.37, 2.40, 3.10, 5.40 and 5.70 visits of honey bees per three minutes in one square meter area in comparison to rest treatments. While maximum visits were recorded in untreated plot i.e., 7.11, 7.55, 7.72, 8.33 and 8.40 visits. Achook and Bioneeem were also found better for the control of aphids (Lipaphis erysimi) as they did not affect bee visits and gave higher yield of 1927 and 1913 kg ha−1, respectively in comparison to plots treated with other pesticides.
