Abstract

Brassica juncea is an annual plant. The flowers have yellow petal. Brassica is an excellent research crop to study patterns of variation in pollinator behavior because it is mostly pollinated by insects and has a rapid life cycle, does not self-pollinate and require insects for cross  pollination. Study was conducted in Bahona college campus located in Jorhat district of Assam from October 2018 to February 2019 during flowering period. Observations of pollinator insects were carried out using scan sampling. 21 species of pollinating insects belonging to 4 orders were found during the study period. Three species of hymenopteran insects showed a high abundance i.e. A. cerana, A. dorsata and Trigona sp. Additionally, ten species of Lepidoptera and three species of Diptera and one species of coleoptera visited mustard flowers. Species richness of pollinator insects increased from 8.00 h to 11.00 h.
