摘要:从印榕仙人掌(Opuntia ficus-indica Mill)植株高度、新增茎片数量和新增茎片面积3个方面研究不同密度胭脂虫Dactylopius coccus Costa寄生对仙人掌生长量的影响。结果表明:1)胭脂虫寄生对寄主仙人掌有明显的抑制作用,未被寄生的仙人掌株高、茎片数量和茎片面积的增加均明显大于被寄生的仙人掌;2)随着胭脂虫寄生密度的增加,仙人掌植株生长量的增加相应减少,生长高峰期的出现也会相应推迟;3)胭脂虫的寄生密度应控制在1000头/株以下,过大会导致仙人掌的死亡。
Effects of different cochineal beetle Dactylopius coccus Costa densities on growth of the host cactus(Opuntia ficus-indica Mill) were measured with regard to three dependent variables;cactus plant height,the number of new cladodes and the area of new cladodes.The results show that:1) D.coccus can inhibit cactus growth;plant height and the number and area of new cladodes were reduced at higher beetle densities.2) The rate of cactus growth decreased and the peak period of growth was also delayed at high beetle density.3) Beetle density should be controlled to be no more than 1 000 beetles per plant;higher densities will lead to cactus death.
