Different species of insects play a crucial role in pollinating cultivated and wild angiospermic plants. Monitoring abundance and biodiversity of these pollinators is an important step in estimating their populations within an ecosystem. Currently, different methods are used for active as well as passive sampling of insect pollinators. Passive sampling methods, such as different colored pan traps and vane traps are widely used for sampling bees. Active sampling via hand-net collection and timed counts are also used for estimating pollinator population. Effectiveness of these methods may vary from one ecosystem to another. This presentation will focus on the utility and effectiveness of these methods, and will also discuss their applicability for sampling bees and other insect pollinators in different ecosystems.
