摘　　要：桂平市地处广西南部,全市荔枝以禾荔、桂味、妃子笑等品种为主,是全国“荔枝之乡”。为摸清荔枝木毒蛾生长习性、掌握其发生发展为害规律。通过观察、记录荔枝木毒蛾幼虫孵化发生发展情况与太阳能频振式杀虫灯诱杀成虫情况发现,荔枝木毒蛾每年3月下旬开始发生,4月上中旬发生为害逐渐加重,中下旬达到高峰,成蛾羽化逐渐增多;5月上旬幼虫大幅减少,成蛾大量羽化;5月上中旬成蛾大幅减少至归零。根据荔枝木毒蛾发生的规律及其发生为害特性,建议在每年的4月上旬幼虫发生为害初期和中下旬发生为害高峰期,使用菊酯类和毒死蜱等复配药喷杀幼虫;利用其较强的趋光性,安装太阳能频振灯大量诱杀成蛾;同时结合清园、集中销毁,有效防控其发生为害。Guiping is located in the southern part of Guangxi and boasts lychee varieties such as Heli,Guiwei,and Feizixiao.It is recognized as the"Home of Lychees"in China.To understand the growth habits of Lymantria xylina Swinhoe in lychees and grasp the rules of its occurrence,development,and damage,we observed and recorded the hatching,occurrence,and development of larvae of Lymantria xylina Swinhoe in lychees,as well as the effectiveness of solar-powered frequency-vibrancy pest-killing lamps in attracting and killing adult Lymantria xylina Swinhoe.The Lymantria xylina Swinhoe in lychees begins to emerge in late March each year.From early to mid-April,the damage gradually intensifies,peaking in mid to late April with an increasing number of adults emerging.In early May,the number of larvae significantly decreases,while a large number of adults continue to emerge.By early to mid-May,the number of adults drops sharply to zero.Based on the occurrence rules and damage characteristics of the Lymantria xylina Swinhoe in lychees,it is recommended to use a combination of pyrethroids and chlorpyrifos to kill larvae during the initial damage phase in early April and during the peak damage period in mid to late April.Additionally,taking advantage of their strong phototaxis,solar-powered frequency-vibrancy pest-killing lamps should be installed to attract and kill a large number of adults.Coupled with garden cleanup and concentrated destruction,these measures can effectively prevent and control their emergence and damage.
