【摘要】 通过开展田埂种植香根草(Vetiveria zizanioides)诱集二化螟(Chilo suppressalis)成虫试验,Bt(苏云金杆菌)、赤眼蜂杀虫卡防治稻纵卷叶螟(Cnaphalocrocis medinalis)试验,以及性诱剂诱捕器、赤眼蜂杀虫卡、阿维菌素防控二代二化螟试验,研究绿色防控技术防治水稻虫害的效果。结果表明,香根草诱集二代二化螟的效果明显;赤眼蜂杀虫卡防治稻纵卷叶螟的效果好于Bt,防治二化螟的效果好于Bt和性引诱器;二化螟性引诱剂诱捕成虫效果明显。更多还原

【Abstract】 Through test of planting Vetiveria zizanioides to trap Chilo suppressalis in the field ridge,Bt and trichogramma insecticidal card prevention and control to Cnaphalocrocis medinalis,sex attractant traps,trichogramma insecticidal card,abamectin prevention and control to second generation C. suppressalis,the effect of the green prevention and control to rice insect pests were studied. The results showed that the trap effect of V. zizanioides was obvious to the second generation of C. suppressali;The prevention and control effect of trichogramma insecticidal card to C. medinalis was better than Bt,whose control effect to C. suppressalis was better than Bt and sexual trap; The effect of sex attractant was obvious in bait C. suppressalis.更多还原
