摘  要：
通过解剖野苹果树(Malus sieversii)枝条,调查和分析了苹小吉丁(Agrilus mali Matsumura)在野苹果树上的空间危害情况。结果表明:幼虫及羽化孔均在树干南面枝条上分布最多,分别为0.93头/m、0.39个/m,幼虫在树干4～5 m范围的枝条上最多,为0.97头/m,而羽化孔在树干7～8 m高度范围的枝条上分布最多,为0.45个/m;羽化孔与侵入孔比值率在树干西面的枝条上最高,为72.06%,而在树干6～7 m范围的枝条上最高,为80.64%;野苹果树受苹小吉丁危害影响,枯枝从5月中旬至8月上旬增量呈现先上升后下降的趋势,且在树干南面4～5 m的高度范围所占比最高,为22.76%;并且利用回归分析了苹小吉丁幼虫、羽化孔、羽化孔与侵入孔比值率、危害枯枝在野苹果树上的垂直分布。本文从苹小吉丁在野苹果树上的空间分布分析,可为综合治理苹小吉丁提供更多理论依据。

摘  要：
Through the dissection of wild apple twigs,the spatial distribution and damage regulation of Agrilus mali Matsumura on the wild apple trees was investigated and analyzed. The results showed that both larvae and feathering holes were distributed on the southern branches of the trunk,which were 0.93 heads/m and 0.39 pieces/m,respectively. The larvae were the highest on the branches of the trunk 4-5 m,which was 0.97 heads/m,while the feathering holes were the most distributed on the branches of the trunk height of 7-8 m,which was 0.45/m. The ratio of the feathered hole to the invading hole is the highest on the branch on the west side of the trunk,which is 72.06%,and the highest on the branch of the trunk 6-7 m,which is 80.64%. The dead branches on wild apple trees from mid-May to early August showed a trend of increasing and then decreasing,and the highest proportion in the height range of 4-5 m in the south of the trunk was 22.76%. The regression analysis was used to analyze the vertical distribution of the larvae,feathering holes,ratio of feathering holes and invading holes,and the dead branches on the wild apple trees. This paper analyzed the spatial distribution of Agrilus mali Matsumura on the wild apple tree,which could provide more theoretical basis for the comprehensive management of Agrilus mali Matsumura.
