摘　　要：为了推进＂绿色植保＂、探明生物导弹在南充市防治玉米螟的效果,减少农药用量及残留和环境污染与防治成本,确保玉米生产、品质和生态环境安全,促进玉米增产增收,采用灯下诱蛾和田间剥查与试验示范相结合等方法,开展生物导弹防治玉米螟效果和效益研究。结果表明,每公顷投放生物导弹30-37对,平均防效78.0%,防治成本139.50-172.50元,比化学农药防治少142.50-168.00元,玉米产量比空白对照区平均高817.8 kg,增产11.0%,增加产值1799.16元,增收节支1941.66-1967.16元。2003—2014年累计示范推广24507.33 hm2,增产2004.21万kg,新增产值4409.26万元,节省防治费用349.23-411.72万元,增收节支4758.49-4820.98万元,减少农药5%杀虫双大粒剂551.41 t或90%杀虫单使用12.87 t。且生物导弹使用简便,劳动强度小,适于老、弱、妇、幼操作,对人畜和环境安全,节省药械和用水,是有机农业、现代农业、绿色和无公害农产品及IBM绿色防控示范园区防治玉米螟、减少化学农药的理想替代产品。In order to promote＂green plant protection＂, reduce the dosage and residue of pesticides andcontrol cost of environment pollution, as well as ensure corn production, quality and agricultural ecologicalenvironment safety, research of control effect and benefit on Ostrinia furnacalis in Nanchong City wasconducted using Bio-Guide Wasp Missile（BGWM）. Compared with the blank control areas, control cost was139.50-172.50 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 reach78.0%. Average corn yield per hectare reached 817.8 kg and was increased by 11.0%. Output value increased1799.16 CNY, so farmers could earn extra 1941.66- 1967.16 CNY per hectare. Cumulative demonstrationareas in Nanchong City were up to 24507.33 hm2, total corn yield, output value and saved cost increased20.0421 million kg, 44.0926 million CNY, 47.58-48.21 million CNY from 2003 to 2014, respectively. Controlcost reduced 3.4923- 4.1172 million CNY. Using BGWM decreased 5% dosage ThiosultapdisodiumMacrogranule by 551.41 t, or 90% Monosultap by 12.87 t. Moreover, BGWM was simple to use, suitable for allages, 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 organicagriculture, modern agriculture, the production of green and pollution- free agricultural products, and IBMprevention and control demonstration gardens.
