| 作者于2006年夏季在河南信阳地区系统比较了二化螟性诱芯中Z11-/Z9-16∶Ald及Z13-18∶Ald剂量对2个世代的二化螟雄蛾诱捕量的影响。结果表明,二化螟越冬代成虫诱捕试验中,2个最佳配方中Z11-/Z9-16∶Ald分别为9∶1和8∶2,而比例在7∶3~1∶9之间的诱芯则无引诱作用。如果保持诱芯中Z11-16∶Ald和Z9-16∶Ald的剂量一致且质量比控制在2∶1,则二化螟诱捕量随诱芯中所含Z13-18∶Ald剂量的增加而下降。所有诱芯在二化螟第一代引诱效果显著下降,但该时期组分为Z11-16∶Ald(2)、Z9-16∶Ald(1)、16∶Ald(0.7)和Z13-18∶Ald(0.37)的诱芯诱捕量显著优于其他配比。 |
| 英文摘要: |
| The effects of Z11-/Z9-16∶Ald and the dosage of Z13-18∶Ald contained in some pheromonal lures on Chilo suppressalis trap catch were systematically compared.The results showed that,in trapping trails during the flight season of over-wintered C.suppressalis,the optimal ratios of Z11-16∶Ald and Z9-16∶Ald were 9∶1 and 8∶2,respectively,which was close to the natural ratio(10∶1) contained in the sex pheromone.However,the lures with Z11-/Z9-16∶Ald ranging from 7∶3 to 1∶9 showed no attractant effects.If the total dosage of Z11-16∶Ald and Z9-16:Ald was kept at the same level and the ratio at 2∶1,but the dosage of Z13-18∶Ald contained in the lures was raised,the trap catches of C.suppressalis decreased.The trapping efficiency of all lures,however,decreased dramatically in the first generation,and a lure containing Z11-16∶Ald(2),Z9-16∶Ald(1),16∶Ald(0.7),and Z13-18∶Ald(0.37) was significantly better than all other lures for trapping C.suppressalis. |
