不同诱剂对橘小实蝇的田间诱集效果比较

Trapping Efficacy of Different Attractants on Bactrocera Dorsalis Hendel in Red Meat Honey Pomelo Orchards

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（30 d ），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＆#177;3.9）头＆#183;瓶-1、（114.8＆#177;27.7）头＆#183;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5 d为时间区间分析，在1～10 d的2个时间段好田园物理诱黏剂的田间诱蝇量最高；在21～25 d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。

The comparison in field trapping efficacy on B .dorsalis was carried out for zhenfengkexing sticky-trap and 3 attractants 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 ＆#177; 27.7） and （15.0 ＆#177; 3.9） head ＆#183; 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 4 attracts 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 -5 d and 6 -10 d after treatment ;（2） during the 20 -25 d after 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 .
