Abstract: In order to promote “green plant protection”, reduce the dosage and residue of pesticides and control cost of environment pollution, as well as ensure corn production, quality and agricultural ecological environment safety, research of control effect and benefit on Ostrinia furnacalis in Nanchong City was conducted using Bio-Guide Wasp Missile (BGWM). Compared with the blank control areas, control cost was 139.50-172.50 CNY in area which was put into 30-37 pairs of BGWM per hectare, and that was 142.50-168.00 CNY less than the cost in areas using chemical control. And the average control effect could reach 78.0%. Average corn yield per hectare reached 817.8 kg and was increased by 11.0%. Output value increased 1799.16 CNY, so farmers could earn extra 1941.66-1967.16 CNY per hectare. Cumulative demonstration areas in Nanchong City were up to 24507.33 hm2, total corn yield, output value and saved cost increased 20.0421 million kg, 44.0926 million CNY, 47.58-48.21 million CNY from 2003 to 2014, respectively. Control cost reduced 3.4923-4.1172 million CNY. Using BGWM decreased 5% dosage Thiosultapdisodium Macrogranule by 551.41 t, or 90% Monosultap by 12.87 t. Moreover, BGWM was simple to use, suitable for all ages, safe to human and environment, had low labor intensity, and could save spraying equipment and water. Therefore, BGWM is the ideal substitute for chemical pesticide for controlling Ostrinia furnacalis in organic agriculture, modern agriculture, the production of green and pollution-free agricultural products, and IBM prevention and control demonstration gardens.
