| 摘 要： | ［目的］ 明确5个不同腰果品系对脊胸天牛的抗虫性，为脊胸天牛的综合治理和腰果抗虫育种提供依据。［方法］ 选择20龄腰果无性系果园，在田间自然条件下调查腰果品系CP63 36、FL30、GA63、HL2 13、和HL2 21的脊胸天牛田间发生为害情况，分析其对脊胸天牛的抗虫性。［结果］ 腰果品系CP63 36对脊胸天牛最敏感，其蛀害指数为90.00%，为高感品系。其次为对照腰果品系FL30，其蛀害指数为77.50%。腰果品系HL2 21（44.17%）和GA63（40.00%）的蛀害指数相似，均为中抗品系。腰果品系HL2 13的蛀害指数最低（22.50%），为高抗品系。［结论］ 5个不同腰果品系对脊胸天牛的抗虫性从高到低为HL2 13＞GA63＞HL2 21＞FL30（对照）＞CP63 36。

| Abstract: | Objective] The resistance of five cashew clones to the cashew long-horned beetle,Rhytidodera bowringii White,was evaluated to provide the basis for pest control and pest-resistant breeding.Method] Occurrence of R.bowringii on the five cashew clones named CP63-36,FL30,GA63,HL2-13 and,HL2-21 was investigated under field conditions,and the resistance of different clones to the pest were analyzed.Result] CP63-36 was most susceptible to cashew long-horned beetle,with a damage index of 90.00%,and the resistant... |
