abstract
In agro ecosystem, along with crops weed plants are observed. These weeds can act as a source of floral rewards, for pollinators’ survivability. In this study 14 weed species in uninhabited land (Site I), semi-cultivated land (Site II) and cultivated land ecosystem (Site III) were studied to know the diversity and abundance of insect visitors associated with them by considering Simpson diversity index (SDI), Shannon-Wiener index (H’) and Jaccard index (JI), and also their interrelationship among themself. Where weed plants like Lantana camara L., Alternanthera ficoides (L.), Ageratum conyzoides L., Luffa echinata Roxb. and Celosia argentea L. showed greater association with pollinators diversity. Thus weeds can support pollinators’ diversity even during the floral dearth period of the region. Taking this into view, weed plants can be supported to grow on roadside or fallow lands, also proper planned establishment on bunds in agriculture land can be followed to support pollinator fauna.
