天竺葵品种、胡瓜钝绥螨和花粉对西花蓟马为害水平影响

研究了天竺葵品种、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,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影响,而品种对西花蓟马的为害水平有显著影响,并且品种和胡瓜钝绥螨对西花蓟马的为害水平有交互作用,在每一个相同的胡瓜钝绥螨处理下,西花蓟马对品种Sybil Holmes为害水平明显高于Amethyst 96。在不同品种上,胡瓜钝绥螨作用不同,对于品种Sybil Holmes来说,是否释放胡瓜钝绥螨以及不同释放比例对西花蓟马的为害水平没有影响,而对于品种Amethyst 96,在胡瓜钝绥螨与西花蓟马为1∶2高比例释放胡瓜钝绥螨处理下,西花蓟马的为害水平明显低于1∶10低比例释放和没有释放胡瓜钝绥螨的处理。

The Effect of Cultivars of Ivy Geranium,Amblyseius cucumeris and Pollen on Feeding Damage Rating of Frankliniella occidentalis

The effect of cultivars of ivy geranium,Amblyseius cucumeris and additional pollen on feeding damage rating of Frankliniella occidentalis was studied.The results showed that pollen had no effect on feeding damage rating,Cultivars had significant effect on feeding damage rating,there also had an interaction between cultivar and A.cucumeris.The feeding damage rating was higher on cultivar Sybil Holmes than on Amethyst 96 under the same predator treatment.A.cucumeris had different effects on different cultivars,on cultivar Sybil Holmes,the feeding damage rating was not significant different with or without predators,but on cultivar Amethyst 96,high predator:prey ratio had lower feeding damage rating than lower ratio and no predator.
