对利用信息素诱捕云杉八齿小蠹的策略进行了对比分析,尤其是雄性小蠹的诱捕。第一种策略是障碍法,在林分的周围密集的布置捕捉陷阱,使用交互式信息素分别诱捕雄性小蠹和雌性小蠹。第二种策略是单一诱捕法,广阔使用投有相同诱饵诱捕陷阱,以捕捉最大数量的雄性小蠹为目的,而不包含雌性小蠹的捕捉。在带有低含量的(4S)一反式马鞭草烯醇诱饵混合物中,用0%,1%,10%,35%,60%and90%的(+)-柠檬烯逐步取代α-蒎烯。这种替换对雄性小蠹的反映数量没有影响,但对雄性小蠹的捕捉量稍有影响。在有高含量(4S)-反式马鞭草烯醇捕捉雌性小蠹的引诱剂混合物中,用1-甲氧基-2-丙醇取代2-甲基-3-丁烯-2-醇,对雌性小蠹的捕捉率没有影响。因而,在具有反式马鞭草烯醇和(4县)-2-甲基-6-甲基-2,7-辛-4-醇的混合物中使用1-甲氧基-2-丙醇,捕捉效果没有明显的变化。在单一捕捉的引诱剂混合物中,用(+)-柠檬烯取代α-蒎烯,用1-甲氧基-2-丙醇取代2-甲基-3-丁烯-2-醇,α-蒎烯被代替后对雄性小蠹的捕捉率轻微的影响,但2-甲基-3-丁烯-2-醇被代替后,将不会没有明显地降低捕捉效果。
The strategy of using pheromone trapping spruce (Pterodactylus) was comparatively analyzed, especially the trapping of male beetles. The first strategy is the Barrier, where trap traps are densely arranged around the stands, using interactive pheromones to trap male beetle and female beetle, respectively. The second strategy is the single trapping method, which is widely used to trap traps with the same bait to capture the largest number of male beetles without the capture of female beetles. Alpha-pinene was gradually substituted with 0%, 1%, 10%, 35%, 60% and 90% (+) - limonene in a low content of (4S) -transfeverine enol bait mixture. This substitution has no effect on the number of male beetles, but slightly affects the male beetles’ catch. In an attractant mixture with high levels of (4S) -trans verbenal enol catching female beetles, 2-methyl-3-buten-2-ol was replaced with 1 -methoxy- The capture rate of female beetle has no effect. Thus, 1-methoxy-2-propanol was used in a mixture with trans verbena enol and (4x) -2-methyl-6-methyl-2,7-octan-4-ol to capture No significant change in effect. In a single captured attractant mixture, α-pinene was replaced by (+) - limonene and 2-methyl-3-buten-2-ol was replaced by 1- The substitution of alkene has a slight effect on the capture rate of male beetles, but the substitution of 2-methyl-3-buten-2-ol will not significantly reduce the catching effect.
