摘要
采用三因子随机区组试验,研究了凤仙花品种、释放胡瓜钝绥螨和添加花粉对西花蓟马为害水平的影响.结果表明,凤仙花品种和释放胡瓜钝绥螨对西花蓟马的为害水平有显著影响,西花蓟马为害水平在品种‘Impulse Or-ange’上明显高于品种‘Cajun Carmine’,西花蓟马为害水平在释放胡瓜钝绥螨处理下明显低于没有释放胡瓜钝绥螨处理,但高、低比例释放胡瓜钝绥螨对为害水平没有影响.是否添加花粉和添加花粉的时间对西花蓟马的为害水平没有显著影响.
The feeding damag block design. cant effect on effect of cultivars of impatiens, release of Amblyseius cucumeris and additional pollen on e rate of Frankliniella occidentalis was studied by the experiment of randomized complete The results showed that the cultivars of impatiens and release of A. cucumeris had a signififeeding damage rate of F. occidentalis. The feeding damage rate was greater on the cuhivar ＇Impulse Orange＇ than on ＇Cajun Carmine＇. The feeding damage rate was greater on the cultivar＇ Impulse Orange＇ than on ＇ Cajun Carmine＇. The feeding damage rate was lower when the predators were released than when they were absent, however, the difference between high ratio predator：prey and low ratio was not significant. Adding pollen to impatiens had no effect on feeding when it was added. damage rate regardless of
