不同混交林分中白蜡窄吉丁幼虫空间格局分析
Spatial distribution of Agrilus planipennis larvae in different mixed forests
摘要
Abstract
To effectively manage the damage of the major trunk borer Agrilus planipennis,geostatistical methods were used to analyze the spatial distribution pattern of A.planipennis larvae in three types of mixed forests in Collective Forest Farm in Lucheng town,Tongzhou district,Beijing.The results showed that number of A.planipennis adult exit holes at 1-2 m high of the trunk height in the vertical direction was significantly higher than those below 1 m and above 2 m(P<0.01).In the horizontal direction,number of larvae in the western direction was significantly higher than that in the eastern,southern,and northern directions(P<0.01).The spatial models established for different mixed forests in the horizontal directions,including linear model(interplant mixed forest),spherical models(strip mixed forest),and exponential model(block mixed forest).The spatial distribution of A.planipennis larvae was random in interplant mixed forests and aggregated in strip or block mixed forests.Kriging interpolation analysis indicated that interplant mixed forests had a lower likelihood of pest infestations compared to strip or block mixed forests.The larvae population gradually diminishes from the central aggregation points towards the surrounding regions.Strip mixed forests and block mixed forests damaged by A.planipennis,exhibited a notable edge effect,with pest occurrences demonstrating a pattern of spatial aggregation.Prevention and control measures for A.planipennis larvae could be implemented based on these aggregation points and dispersal directions.关键词
