Abstract
The presence of insect pollinators plays an important role in the pollination process. This is because the insects move the stamens from the anthers to the stigma, causing fertilization. The purpose of this study is to analyse the diversity of insect pollinators in vegetable plantations in 3 villages at Kecamatan Dolat Rayat, Kabupaten Karo. Sampling was carried out on five types of plantation: bean plant, chayote, peas, eggplant, and chilli. At each sampling point, five plots of 1,2m x 10m were established with a spacing of 2m between the plots. Insect pollinator observation technology using sampling scan method combined with insect net. The results of the study identified 7 families of 10 species and 880 individuals. Diversity index that used is The Shannon-Weiner with an average of H^= ± 1,20 in the villages. The most prevalent order was Apidae, and the most abundant species was Apis cerana. The greatest variety of pollen hybrids was found on chayote plantations. Flower anthesis is used as determinant of this observation.
