Abstract

The study on insect pollinators of corn in Phitsanulok province. by using simple randomly sampling method was carried out during June to July 2017. The total number of insect pollinators was 16 species, in 8 families and 3 orders. The highest number of obtained species was in order Hymenoptera with 10 species, 7 genera and 3 families followed by insects in the Lepidoptera (3 species, 3 genera, 2 families) and Diptera (3 species, 3 genera, 3 families). The most common time for insect pollination was from 08:00 am to 10:00 am. and the lowest pollination was 3.00 pm. to 4.00 pm. The species diversity index showed that species diversity of insect pollinators in the study area is low (J' = 0.100) while the dominant index showed high dominant species (C = 0.547). Apis florea Fabricius, 1787 is the most common pollinator among the other species found in this study (with 71.44% frequency compared to all obtained species).
