于2008年3月柚子花期,将柚园划分为两个区域,一个区域引迁黄蚁,另一个区域不做处理作为对照。在2个区域分别选取20个枝条共40枝,对柚子花期主要害虫(柑桔花蕾蛆、蓟马)及健叶率进行调查。结果表明:对照区柑桔花蕾蛆和蓟马的虫口密度及虫花率都显著高于处理区,而且虫口数量一直保持在较高的水平;有黄蚁存在的情况下,柚子树花蕾蛆的有虫花率减少了70%～80%,蓟马有虫花率减少了近60%,健叶率增加了30%左右。建议在今后害虫综合防治中,充分认识到黄蚁对害虫的防治作用,通过保护和引迁黄蚁来有效防治害虫。
In March 2008 grapefruit flowering, the pomelo garden is divided into two regions, one area leads to the yellow ants, the other area is not treated as a control. 40 branches of 20 branches were selected in the two regions to investigate the main pests of citron (flower bud maggot, thrips) and healthy leaf rate of grapefruit at flowering stage. The results showed that the population density and pest blossom rate of citrus bud maggot and thrips were significantly higher than those of the treatment area, and the population of pest population kept at a relatively high level. In the presence of the yellow moth, Of the pest blight rate decreased by 70% to 80%, thrips pest rate decreased by nearly 60%, the rate of healthy leaves increased by 30%. It is suggested that in the future comprehensive pest management, the prevention and control of pests by the yellow ants should be fully recognized, and the pests should be effectively controlled by protecting and inducing the yellow ants.
