摘要: 为精准防控烟草金龟甲为害,采用定点诱捕法研究了4种光波对贵州省威宁县烟田金龟甲成虫的诱集效果及其对主要益虫的安全性。供试4种诱集光波特征分别为:1#,330~420 nm,峰值350、370 nm;2#,330~600 nm,峰值350、380、560 nm;3#,570~680 nm,峰值605、628、650 nm;4#,330~490 nm,峰值350 nm。结果表明,4种光波对金龟甲成虫的诱集效果表现为2#>4#>1#>3#,其中2#光波的诱集效果最好。2#光波对小阔胫玛绢金龟、阔胫玛绢金龟和东方绢金龟3种关键金龟甲的诱集数量最多,累计为 1 693头,占该光波诱集总量的26.19%;4#光波次之,累计诱集1 215头,占比为26.80%。安全性分析显示,2#光波的诱集益害比最低,为0.016。趋光节律研究表明,金龟甲夜间趋光活动主要集中于20:00—24:00,3种关键金龟甲在22:00—24:00时段的诱集数量最高(187头),其次为20:00—22:00(96头)。综合分析认为,2#光波对金龟甲害虫及关键种类的诱集效果最优,且益害比最低,在烟田应用中安全性较好,最佳诱集时段建议为20:00—24:00。

Abstract: To achieve precise control of tobacco scarab beetle damage, a fixed-point trapping method was employed to investigate the attraction effects of four light spectra on adult scarab beetles in tobacco fields of Weining County, Guizhou Province, as well as their safety for major beneficial insects. The characteristics of the four tested light spectra were as follows: 1#, 330-420 nm, with peak wavelengths at 350 and 370 nm; 2#, 330-600 nm, with peak wavelengths at 350, 380, and 560 nm; 3#, 570-680 nm, with peak wavelengths at 605, 628, and 650 nm; 4#, 330-490 nm, with a peak wavelength at 350 nm. The results showed that the attractiveness of the four light spectra to adult scarab beetles followed the order of 2# > 4# > 1# > 3#, with spectrum 2# exhibiting the highest attraction effect. Spectrum 2# attracted the greatest number of three key scarab beetle species: Maladera verticalis, Maladera ovatula, and Maladera orientalis, with a cumulative total of 1 693 individuals, accounting for 26.19% of the total insects trapped by this spectrum. Spectrum 4# ranked second, trapping a total of 1 215 individuals, representing 26.80% of its total catch. The safety analysis showed that spectrum 2# had the lowest beneficial-to-harmful insect ratio, with a value of 0.016. Analysis of phototactic rhythm revealed that the nocturnal phototactic activity of scarab beetles was mainly concentrated between 20:00 and 24:00. The highest number of the three key scarab beetle species was trapped during 22:00-24:00 (187 individuals), followed by 20:00-22:00 (96 individuals). Comprehensive analysis indicated that spectrum 2# demonstrated the optimal attraction effect for scarab beetle pests and key species, along with the lowest beneficial-to-harmful insect ratio, indicating good safety for application in tobacco fields. The optimal trapping period was recommended to be from 20:00 to 24:00.
