| 中文摘要: |
| 在杏园蛀果害虫发生期,通过室内饲养和田间诱捕研究了新疆南部地区杏园蛀果害虫发生的种类,结果表明,新疆南部地区杏园蛀果害虫共有4种,分别是李小食心虫Grapholitha funebrana Treitschke、梨小食心虫Grapholitha molesta (Busck)、苹果蠹蛾Cydia pomonella (L.)和桃条麦蛾Anarsia lineatella Zeller,其种群数量分占87.41%、3.81%、2.51%和6.27%;李小食心虫种群数量显著大于梨小食心虫、苹果蠹蛾和桃条麦蛾,为主要种类;梨小食心虫、苹果蠹蛾和桃条麦蛾为次要种类。室内药剂筛选试验结果表明,5%顺式氯氰菊酯乳油、1.2%烟碱·苦参碱乳油(烟碱0.7%,苦参碱0.5%)和5%杀铃脲悬浮剂药后1 d的防治效果差异显著,分别为95.02%、7809%和20.15%;药后5 d,5%顺式氯氰菊酯乳油和1.2%烟碱·苦参碱乳油防治效果分别为89.71%和8030%,无显著差异。综上,新疆南部地区杏园优势蛀果害虫为李小食心虫,5%顺式氯氰菊酯乳油和1.2%烟碱·苦参碱乳油可作为防控用药。 |

| During the occurrence of fruit-boring insect pests, community structure of the pests was investigated in apricot orchards by field trapping and indoor-rearing. The results showed that there were four kinds of fruit-boring insect pests, including Grapholitha funebrana Treitschke, Grapholitha molesta (Busck), Cydia pomonella (L.) and Anarsia lineatella Zeller in apricot orchards in southern Xinjiang. The population percentages of the four pests were 87.41%, 3.81%, 2.51% and 6.27%, respectively. The population number of G. funebrana was significantly higher than that of the other three fruit-boring insect pests, indicating it was the major fruit-boring insect pest, while G. molesta, C. pomonella and A.lineatella was the minor fruit-boring insect pests. Insecticides screening test in laboratory showed that the control efficacies of cis-cypermethrin 5% EC, nicotine·matrine 1.2% EC and triflumuron 5% SC were 95.02%, 78.09% and 20.15% on 1st day after treatment, respectively, with significant difference among the three treatments. The control efficacies of cis-cypermethrin 5% EC and nicotine·matrine 1.2% EC were 89.71% and 80.30% on 5th day after treatment, respectively, with no significant difference. As a result, G. funebrana was the dominant fruit-boring insect pest in the apricot orchards in southern Xinjiang, and cis-cypermethrin 5% EC and nicotine·matrine 1.2% EC could be used for the pest prevention and control. |
