摘要:
开展了4种诱剂对橘小实蝇的田间诱集效果比较试验, 结果表明:在整个试验期间 (30d) , 好田园物理诱黏剂在最高单日诱蝇数量和诱蝇总量上都最高, 分别为 (15.0±3.9) 头·瓶-1、 (114.8±27.7) 头·瓶-1, 均极显著或显著高于诱蝇醚、翼牌果蝇草本芳香诱剂和针锋克星粘板。在不同时间段内, 4种诱剂的诱集性能具有明显差异, 以5d为时间区间分析, 在110d的2个时间段好田园物理诱黏剂的田间诱蝇量最高;在2125d的时间段, 翼牌果蝇草本芳香诱剂的田间诱蝇量显著优于好田园物理诱黏剂;在6个时间段中, 诱蝇醚和翼牌果蝇草本芳香诱剂的田间诱集效果相当, 两者比较无显著差异;针锋克星粘板诱集的有效期最短, 诱集效果最差, 与空白对照无显著差异。好田园物理诱黏剂田间诱集效果速效性突出, 可推荐在危害高峰期使用, 以快速降低雄虫虫口密度, 翼牌果蝇草本芳香诱剂和诱蝇醚的持效性期较长, 可用作为监测虫情及长期防治使用。
Abstract:
The comparison in field trapping efficacy on B.dorsalis was carried out for zhenfengkexing sticky-trap and 3attractants such as Yi′brand Herbal aromatic attractant (Yi′brand) , Haotianyuan′physical induced adhesive (Haotianyuan′) and Methyl eugenol, in red meat honey pomelo orchard.The results showed that the numbers of B. dorsalis attracted by Haotianyuan′was maximal in overall trial (30d) and single-day for (114.8±27.7) and (15.0 ±3.9) head·bottler-1, respectively, which were significantly higher than those of‘Yi'brand, Methyl eugenol and Zhenfengkexing sticky-trap.The differences in field trapping efficacy of 4attracts were remarkable for various trapping time schedule as showed in following: (1) the highest trapping number of B.dorsalis was obtained by Haotianyuan′in two time phases of the 1-5dand 6-10dafter treatment; (2) during the 20-25dafter treatment, the trapping number was significantly lower in Haotianyuan′than in Yi′brand; (3) there was no significant difference in attracting quantity between Yi′brand and Methyl eugenol during entire trial period.Because of the shortest in function time, the quantity of attracted B.dorsalis by zhenfengkexing sticky-trap was the lowest one with no significant difference to the blank control.The results suggest that, by quick function, Haotianyuan′ could be used while the population of B.dorsalis reached in hazard peak to reduce the density of male adult quickly; Yi′brand and Methyl eugenol could be used in monitoring and long-term prevention for controlling of B.dorsalis.
