[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。 |

[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 level was highly susceptible. FL30 was a check clone that was most susceptible to cashew long horned beetle, with a damage index of 77.50%. The damage indexes of HL2 21 (44.17%) and GA63 (40.00%) were similar, both of which were moderately resistant. The damage index of HL2 13 (22.50%) was lower than other clones, which was highly resistant. [Conclusion] The five cashew clones could be ranked from strong to weak resistance as follows, HL2 13, GA63, HL2 21, FL30 and CP63 36. |
