摘要
通过对赣南脐橙园柑橘红蜘蛛(Panonychus citri)的田间调查,发现柑橘红蜘蛛在叶片、树冠和植株3个空间尺度的分布型均为聚集分布;柑橘红蜘蛛在脐橙园的分布常存在中心株,且树冠的各个方位分布无显著差异;卵多产在叶的主脉两侧,尤以叶基部主脉两侧居多。根据赣南脐橙园柑橘红蜘蛛分布规律,提出了相应的防治对策。
According to field investigation in a navel-orange orchard in South Jiangxi,the distribution types of citrus red mites were clumped at three spatial scales of leaves,tree crowns and tree individuals.There existed ＂center strains＂ among the distribution of the citrus red mites in the orchard;and there was no significant difference among tree crown areas in different directions.Eggs were usually oviposited along both sides of the main leaf vein,especially in the leaf bases.Finally,based on the above distribution patterns of citrus red mites,corresponding control strategies were put forward.
