【摘要】 柑橘粉虱Dialeurodes citri Ashmead和柑橘潜叶蛾Phyllocnistis citrella Stainton是柑橘的主要害虫,为了评估施肥对其发生的影响,本研究调查了施用有机肥、化肥、复混肥(有机肥与化肥混合)的砂糖橘苗木上这两种害虫的发生危害情况。结果表明,施用有机肥的苗木上柑橘粉虱的卵和若虫数量显著低于化肥,由柑橘粉虱诱发的煤污病发病程度也显著低于化肥处理。有机肥处理柑橘粉虱成虫数量也最少,但与化肥、复混肥差异未达显著水平。另外,柑橘潜叶蛾为害情况在3种肥料处理之间则没有显著差异。说明施有机肥的砂糖橘对柑桔粉虱的吸引作用最弱,其次为复混肥,化肥最吸引柑橘粉虱。3种施肥处理对柑橘潜叶蛾的吸引作用差异不明显。更多还原

【Abstract】 Citrus whitefly Dialeurodes citri and citrus leafminer Phyllocnistis citrella are important citrus pests. In order to assess the effect of different fertilizers applying in citrus on these pest species, the numbers of adult, egg and nymph of this whitefly and the damage of citrus leafminer on the citrus young plants treated by 3 kinds of fertilizer, organic, chemical and mixture(mixture of organic and chemical fertilizer) were monitored in a greenhouse. The results showed that although there was no significant difference of settling adults among the 3 treatments, the numbers of egg and nymph of citrus whitefly on the organic fertilizer-treated citrus were significantly fewer than the chemical fertilizer treatment. And the index of sooty mold caused by the whitefly of organic fertilizer treatment was also lowest. However, the damage indexes caused by citrus leafminer were not significantly different among the 3 treatments. The results indicated that applying of the organic fertilizer had the weakest attraction to citrus whitefly, followed by compound fertilizer, and the chemical fertilizer was the most attractive for this pest. However, the three fertilization treatments had little difference in the attraction of citrus leaf miner.更多还原
