【摘要】 采用黃板和黑光燈誘集法分別在北京和福建評價了夜蛾斯氏線蟲(Steinernema feltiae)控制雙孢磨菇(Agaricus bisporus)眼蕈蚊(sciarid flies)的效果。黃板誘集結果表明,施用線蟲后眼蕈蚊種群數量大幅度降低,北京點處理后第19天的蟲口減退率達68.8%;福建點處理后第33天的蟲口減退率達81.9%;殺蟲燈誘集結果表明,施用線蟲后12 d,對照菇房平均日誘蟲量3.59萬頭,處理菇房平均日誘蟲量2.67萬頭。大蠟螟誘集法檢測發現,線蟲施入培養料后58 d,對大蠟螟致死率3 d達87.5%,5 d達100%;線蟲施入培養料后120 d對大蠟螟幼蟲致死率3 d仍達52.6%。
【Abstract】 Both the yellow sticky trap and light trap methods were used to evaluate the efficacy of the entomopathogenic nematode Steinernema feltiae in controlling sciarid flies in Agaricus bisporus mushroom beds over a two year period in Beijing and Fujian Province.Nematode suspensions containing 100 IJs/m2were sprayed onto the mushroom beds after the first mushroom harvest.Tests using the yellow sticky trap revealed that sciarid populations were reduced by 68.8% after 19 days and 81.9% after 33 days following treatment compared with untreated controls.Averages of 26 700 and 35 850 sciarid flies per day were captured by the nematode treatments and in light traps,respectively.Nematode persistence was determined using the wax moth(Galleria mellonella) trapping assay.Mortality rates for 5th instar larvae of G.mellonella were 87.5% and 52.6% after 58 and 120 days,respectively following application to the compost.
