不同聚集信息素诱芯及诱捕器对大豆田间点蜂缘蝽诱捕效果研究

随着大豆"症青"发生面积的逐步扩大,点蜂缘蝽已引起了大豆科研工作者与生产者的高度重视。为探讨高效的点蜂缘蝽诱捕技术,本研究于2019年8月份在安徽省当涂县用不同诱芯、诱捕器及其组合评价聚集信息素对点蜂缘蝽的诱捕效果。方差分析表明:诱芯、诱捕器及其互作间诱捕效果差异都达极显著水平。缓释包诱芯1-2和PVC诱芯2-2显著高于橡胶塞诱芯3-x和空白对照。小船型诱捕器和双向倒漏斗型诱捕器显著高于通用桶型诱捕器和绿色粘虫板。PVC诱芯2-2、缓释包诱芯1-2和小船型诱捕器的组合效果最佳,但小船型诱捕器底部组件粘虫板会粘住点蜂缘蝽导致点蜂缘蝽死亡。缓释包诱芯1-2、PVC诱芯2-2和双向倒漏斗型诱捕器的组合效果次之,且其能诱捕到点蜂缘蝽完整活体,可为进一步研究提供试虫。对诱捕到的昆虫种类分析表明:试验期间诱到的蛾类昆虫相对较多,特别是橡胶塞诱芯3-x对蛾类有较强的引诱效果;不同诱芯、诱捕器都只诱到少量蜂类昆虫;绿色粘虫板较其它诱捕器粘到显著更多的瓢虫类昆虫。PVC诱芯2-2、缓释包诱芯1-2和小船型诱捕器、双向倒漏斗型诱捕器组成的4种组合能引诱到较多点蜂缘蝽,且其它昆虫较少,说明有较高的专一性,实用性。

Study on the Trapping Effect of Different Aggregation Pheromone Lure Cores and Trap Devices Against Riptortus pedestris in Soybean Field

With the gradual expansion of the area of soybean ’Zhengqing’, the Riptortus pedestris has attracted the attention of soybean science and technology workers and producers. In order to explore the high efficient trapping technique of Riptortus pedestris, this study evaluated different lure cores of the aggregation pheromone, trap devices and their combinations in August in Dangtu county, Anhui province. The analysis of variance showed that the trapping effect of trap device, lure core and their interactions reached a very significant level. The slow-release lure core 1-2 and PVC lure core 2-2 were significantly higher than the rubber plug lure core 3-x and blank control. The small boat trap and the two-way inverted funnel trap were significantly higher than the general bucket trap and the green stick board. The combinations of the PVC lure core 2-2 and the slow-release lure core 1-2 and the small boat trap was the best, but R. pedestris would be sticked to the sticking plate at the bottom of trap and die. The combinations of the slow-release lure core 1-2 and the PVC lure core 2-2 and two-way inverted funnel trap could capture alive R. pedestris, which could provide test insects for further scientific research. The analysis of the species of the trapped insects showed more moth insects were attracted during the whole experiment, especially the rubber plug lure core 3-x had strong attracting effect on moths. Different lures core and trap devices only attracted a small number of bee insects. Green sticky board significantly captures more ladybug insects. The PVC lure core 2-2, the slow-release lurecore 1-2 and the small boat trap, the two-way inverted funnel trap were best combinations which could attract more R. pedestris and fewer other insects, indicating a high degree of specificity and practicability.
