We have surveyed the current status of insect pollinator use for horticultural crops in 2016. The use rate and farmnumber of insect pollinators for 26 horticultural crops were 25.8% and 55,208, respectively. The colony number of insectpollinators used in this survey was 479,777, which include 344,690 for honeybees, 119,104 for bumblebees, 2,415 formason bees, 1,317 for flies, and 2,415 for the combination of bumblebees, honeybees, and mason bees. The use rateof insect pollinators was 59.4% for 11 vegetable crops and the colony number of insect pollinators used for 11 vegetablecrops was 449,287. The colony number of insect pollinators used for 15 fruit tree crops was 30,290, which include honeybees(66.3%), bumblebees (20.2%), mason bees (8.0%), flies (1.6%), and the combination (3.9%) of bumblebees, honeybees,and mason bees. Together, farms of 98% showed positive effect for the use of insect pollinators and most of farms (97.0%)planed for the continuous use of insect pollinators

본 연구의 목적은 방화곤충에 의해 유전자변형 작물로부터 비변형작물로의 유전자 이동이 일어날 수 있는가를 조사하기 위한 프로토콜을 개발하는 것이다. 이를 위해 제초제저항성 형질전환 콩과 재배콩인 태광콩, 그리고 G. soja 시험구에서 발생하는 곤충상을 sweeping법으로 조사하였으며, 이들 시험구에서 화분매개 가능성을 가진 방화벌의 시간대별 출현빈도 및 부위별 화분 부착율을 조사하였다. 또한 채집한 서양종꿀벌로부터 부착된 화분을 이용, 핵산을 추출하고 PCR 증폭 가능성 여부를 분석하였다. 그 결과, 유전자변형 콩과 비변형 콩 사이의 곤충상에는 시기별로 유의성 있는 차이는 없는 것으로 조사되었다. 개화기 콩 꽃에서 서양종꿀벌의 출현빈도는 정오에 가장 높은 것으로 나타났다. 이들이 수확한 화분으로부터 핵산을 추출하여 PCR 을 수행하였을 때 lectin 유전자가 증폭된 것으로 보아 이들 화분은 콩으로부터 유래한 것임을 확인하였다.

The current status of insect pollinator use was surveyed. Honeybee was larger than mason bee and bumblebee in average use area per farm household at kinds of insect pollinator. Insect pollinator was used at 19 crops. Among them, tomato was the most used crop, which was 44.9%, and in order to apple 26.7%, strawberry 13.1%, red-pepper 7.7% and watermelon 3.7%. In the use of insect pollinators, bumblebee, which was 56.9%, was higher than honeybee (31.3%) and mason bee (11.8%). The most farmers were a positive intention except for 1.5% of farmer in the use of insect pollinator for crop pollination. The best advantage in insect pollinator use was improvement of seed setting percentage, which was 28.3% and the worst problem was low activity at bad weather, which was 25.8%. And also, 97% of farmers have an intention to use continuously insect pollinator.
