| 摘 要： | 文章对乐山市绿心公园内三叶虫萤成虫的生境和夜间活动规律进行了调研。研究结果表明,三叶虫萤栖息在停耕农田以禾本科植物为主,密度约110株/m2,栖息在草地以艾草为主,密度约为100株/m2,周边屏障植被种类主要有慈竹等。植被平均高度为44.2cm,土壤面上都有一层厚度约为11cm的枯草。三叶虫萤的种群密度约为4.8-8.1只/m2,在一定范围内,栖息地面积越大,三叶虫萤的密度越大。三叶虫萤在平坦区域几乎为均匀分布,在狭沟或不平坦的栖息地则分布不均匀。三叶虫萤在19：30左右周边光照度约为10.4 Lux时开始零星闪光,在20：00-21：30周边光照度约为0.1 Lux时发光达到高峰。雄性成虫夜晚活动旺盛,一次飞行距离0.5-8.0m,飞行高度0.3-2.6m;雌性成虫夜晚活动不活跃。成虫活跃期间平均温度为18℃,空气湿度为94%。栖息地土壤类型为壤土,湿度为38.47%。

| Abstract: | The paper reports the habitat and night activity regularity of the adult Emeia pseudosauteri at Lvxin Park in Leshan City.The results shows that Emeria pseudosauteri live in the stop-farming land in which the gramineous plants are the major species with the density of about 110 per square meter,or on lawn which are predominated by Artemisia argyi with the density of about 100 per square meter.The main vegetation types of surrounding barrier are Sinocalmus affinis,etc.In habitat,the average height of vegetations are 44.2 cm,and there are some withered grass with the thickness of about 11 cm on the soil surface.Normally,the density of Emeria pseudosauteri are about 4.8-8.1 per square meter within a certain range,the larger the habitat area,the greater the density.In the flat areas the fireflies would be almost distributed averagely,otherwise the distribution would be uneven.Emeria pseudosauteri would start to wink at around 7：30 P.M with the surrounding illuminance of about10.4 Lux,and would reach peak luminosity at 8：00-9：30 P.M with the surrounding illuminance of about 0.1 Lux.The male adult Emeria pseudosauteri activite stronger at night with the flight distance of 0.5 to 8.0 m for each flight and the flight altitude of 0.3 to 2.6m,but the female adult are less active during the night.The average temperature is 18℃ and air humidity is 94%during the active phase of adult Emeria pseudosauteri.The habitat soil is doras with the humidity of 38.47%. |
