| 中文摘要: |
| 脐腹小蠹是新疆果树林木的重要害虫, 研究不同寄主对脐腹小蠹取食和繁殖的影响可为脐腹小蠹的综合治理提供参考。田间诱集试验表明, 脐腹小蠹为害‘赛买提’杏、扁桃和新疆桃, 不为害垂柳和沙枣, 在春榆上也诱集到少量成虫, 但其数量显著低于‘赛买提’杏、扁桃和新疆桃。室内饲养研究表明, ‘赛买提’杏、扁桃和春榆上均有脐腹小蠹取食为害, 其中‘赛买提’杏上脐腹小蠹子代数量最多, 成虫蛀道长度最长, 侵入孔数最多, 与扁桃和春榆差异显著。综上所述, 脐腹小蠹在‘赛买提’杏、扁桃、新疆桃、春榆上均可完成发育, 但在4种寄主上的子代数量以及对4种寄主的为害程度不同, ‘赛买提’杏是脐腹小蠹生长发育及繁殖的最适寄主, 其次是扁桃、新疆桃, 脐腹小蠹也可为害春榆。 |

| Scolytus schevyrewi Semenov is an important pest of fruit trees in Xinjiang, this study was to investigate its damage, development and reproduction on different hosts, and thus provide some useful information for its comprehensive management. The laboratory research and field investigation found that S. schevyrewi damaged Prunus armeniaca (‘Saimaity’ apricot), Amygdalus communis Linn., Amygdalus ferganensis (Kost. et Riab.) Kov. et Kost, Ulmus propinqua (Koidz.), but not Salix babylonica Linn. and Elaeagnus angustifolia Linn.; the heaviest body weight of subalgebra adults, the most number of offspring generations, the longest tunnels, and the maximum number of invasion holes were observed on P. armeniaca, followed by on A. communis, A. ferganensis, and U. propinqua. The laboratory research found that the most number of offspring generations, the longest tunnels, and the maximum number of invasion holes on P. armeniaca, significantly different from those on A. communis and U. propinqua, but no significant difference in the body weight of offspring adults was observed in these four hosts. Field results showed that there were the catches of adult and invasion holes on P. armeniaca, significantly different from those on U. propinqua. Therefore, among the six hosts investigated, P. armeniaca, A. communis, A. ferganensis and U. propinqua had no significant influence on the development of S. schevyrewi, but they had some influence on the quantity of reproduction. P. armeniaca is the most suitable host for development and reproduction of S. schevyrewi, followed by A. communis and A. ferganensis. The S. schevyrewi could also damage and reproduce on U. propinqua, but not damage S. babylonica and E. angustifolia. |
