摘要
为了解河南漯河劳氏粘虫的种群动态,于2022年利用测报灯、探照灯和性诱剂诱捕器对其田间种群进行了监测,并分析比较了监测和诱捕效果。结果表明,2022年测报灯和探照灯下劳氏粘虫成虫种群消长动态均有1个高峰期,且均在9月上旬至10月中旬,峰期一致,峰期虫量分别占当年诱虫总量的94.38%和95.58%;性诱剂诱捕器诱虫的主要时期在9月20日至10月21日,其间3个诱捕器平均诱虫量占监测期内诱捕虫量的90.05%,性诱剂诱捕器与测报灯和探照灯的诱捕高峰期基本吻合。测报灯、探照灯和性诱剂诱捕器的诱虫高峰日分别在9月29日、9月26日和9月23日。不同位置的性诱剂诱捕器对劳氏粘虫的诱捕效果有显著差异。监测期间,劳氏粘虫诱芯诱捕到的劳氏粘虫雄蛾数量占总诱捕虫量的98.20%,显著高于其他各类昆虫,专一性较好。研究结果可为劳氏粘虫的预测预报和绿色防控提供参考。
To understand the population dynamics of Leucania loreyi in Luohe,Henan,field populations were monitored in 2022 using forecast lamps,searchlight,and sex attractant traps.The monitoring and trapping efficacy were analyzed and compared.The results showed that both forecast lamps and searchlight captured adult Leucania loreyi populations with a single peak period from early September to middle October in 2022,with peak captures accounting for 94.38%and 95.58%of the annual totals,respectively.The primary capture period for sex attractant traps was between September 20 and October 21,during which the average capture across three traps represented 90.05%of the total monitoring period.The peak capture periods of sex attractant traps largely aligned with those of the forecast lamps and searchlight.The peak capture dates for forecast lamps,searchlight,and sex attractant traps were September 29,September 26,and September 23,respectively.The trapping efficacy of sex attractant traps varied significantly depending on their locations.Throughout the monitoring period,male Leucania loreyi accounted for 98.20% of the total insects captured by the attractant traps,significantly outnumbered other insect species and demonstrated high specificity.These findings provide valuable insights for forecasting and eco-friendly control strategies against Leucania loreyi.
