中文摘要:
【目的】 明确粘虫板颜色和悬挂方式对枣飞象Scythropus yasumatsui成虫的诱集效果,为枣飞象的科学监测和绿色防控技术提供理论依据。【方法】 2018年4月至2020年5月,在陕北佳县枣园分别测定6种颜色粘虫板(黄绿色、黄色、深绿色、白色、红色、蓝色)、5种悬挂高度(0.4、0.8、1.2、1.6、2.0 m)、5种悬挂方位(正东、正南、正西、正北、正中)和4种悬挂密度(20、30、40、50张/667 m2)对枣飞象成虫的诱集效果。【结果】 黄绿色粘虫板诱集效果最好,日均诱集数量7.3头/板,显著高于其它5种颜色(P<0.05),深绿色次之,白色、红色和蓝色诱集效果差异不显著,黄色粘虫板诱集效果最差,日均诱集数量1.8头/板,显著低于其它5种颜色(P<0.05)。粘虫板不同悬挂高度对枣飞象诱集量由高到低依次为:0.8 m>0.4 m=1.2
m>1.6 m>2.0 m,悬挂高度为0.8 m时日均诱集量最高,为8.3头/板,显著高于其它4种高度(P<0.05)。粘虫板悬挂在正南方位,日均诱集枣飞象成虫数量显著高于其它4个方位(P<0.05),正东和正中方位次之,西方和北方日均诱集量显著低于其它3个方位(P<0.05)。相比于其它设置密度,20张/667 m2为最经济高效的悬挂密度。【结论】 在枣园进行枣飞象监测和防控时,粘虫板颜色为黄绿色,悬挂高度为距离地面0.8 m,悬挂方位为正南方、悬挂密度为20张/667 m2的试验组合对枣飞象成虫诱集效果最好。
英文摘要:
[Objectives] To investigate the relative effectiveness of
different colored sticky cards and hanging modes to trap Scythropus yasumatsui, and thereby improve the monitoring and
environmentally-friendly control of this pest. [Methods] The trapping
efficacy of different sticky card colors, suspended at different heights,
orientated in different directions and hung at different densities, were tested
in a jujube orchard in Jiaxian county, northern Shaanxi from April 2018 to May
2020. The colors tested
were yellow-green, yellow, dark green, white, red and blue, which were hung at
either 0.4, 0.8, 1.2, 1.6 or 2.0 m above ground. Cards were orientated facing
either due east, due south, due west, due north or centered, at densities of
20, 30, 40 and 50 cards/667 m2. [Results] Yellow-green cards caught a daily average
of 7.3 S. yasumatsui per card; significantly more than the other
five colors (P<0.05). Dark green
cards were the next most effective; there was no significant difference in the
number of insects trapped by white, red or blue cards. Yellow cards caught an
average of 1.8 S. yasumatsui per card; significantly less than
the other 5 colors (P<0.05). The
relative effectiveness of different card suspension heights was, in descending
order: 0.8 m>0.4 m=1.2 m>1.6 m>2.0 m. Cards hung at 0.8 m caught a
daily average of 8.3 insects per
card, significantly higher than the other 4 heights (P<0.05). Cards orientated due south caught significantly more S. yasumatsui than those orientated in other directions (P<0.05), followed by those that were
orientated due east or centered. Those orientated due west or due north caught significantly fewer insects
than those orientated in other directions (P<0.05).
A card density of 20 cards/667 m2 was the most economical and efficient. [Conclusion] Yellow-green color sticky cards hung at a
height of 0.8 m above ground, orientated towards the south and deployed at a
density of 20 cards/667 m2, are most effective for monitoring and
controlling S. yasumatsui in a jujube orchards.
