It should be noted that pollinators are a type of insect that has a role in helping to pollinate one or several types of plants. About 2/3 of all flowering plants require insect pollination to produce optimal seed.
The role of pollinating insects is evident in cross-pollination that can increase agricultural production and increase the quality of genetic and hereditary production (Barth, 1991).
Although flowering can occur throughout the year, but more cultivated plants have short-term and seasonal flowering, leading to the availability of nectar and pollen not occurring throughout the year and tend to fluctuate.
