为探索松墨天牛(Monochamus alternatus Hope)测报技术,在江西赣县区应用聚集性信息素和植物源引诱剂的复合型诱剂于2015—2016年监测松墨天牛成虫消长动态。结果表明,江西南部地区松墨天牛成虫发生期为214~222 d,长达7个多月。成虫于4月上旬始见,5月中旬进入盛期,诱捕高峰期在6月中、下旬,7月下旬至8月上旬为盛末期,发生盛期为63d~84 d。盛期结束后,林间成虫种群处于低密度状态,一直到11月上、中旬结束。全年5月至7月诱捕量合计占全年总数的74.59%~86.34%,这一时期是防治的关键阶段。研究表明,利用该复合型诱剂可以准确地监测林间松墨天牛成虫的种群动态,为防治工作提供可靠的测报数据,省工省时,是值得推广的新技术。
In order to explore the Monochamus alternatus Hope reporting technique, the growth and development of adult Monochamus alternatus adults were monitored in 2015-2016 in a compound lure of aggregated pheromone and plant-derived attractant in Ganxian district, Jiangxi province. The results showed that the occurrence of Monochamus alternatus in southern Jiangxi Province occurred between 214 and 222 days, which lasted for more than 7 months. Adults in early April saw the beginning of mid-May into the peak, the peak trapping period in mid-June, late, late July to early August as the end of Sheng, the peak was 63d ~ 84d. After the peak, the forest adult population in a low density state, until November, mid-end. The total amount of trapping from May to July of the year accounted for 74.59% ~ 86.34% of the total for the whole year. This period was the key stage of prevention and treatment. The research shows that the compound lure can accurately monitor the population dynamics of Monochamus alternatus adults and provide reliable data for the prevention and control work. It is a new technique worthy of popularization and saving time and labor.
