【摘要】 对采自10个地方的仙人掌进行胭脂虫放虫试验,并对仙人掌进行解剖及营养成分分析,结合胭脂虫的生长情况对胭脂虫与仙人掌种类、内部构造及营养成分的关系进行研究,结果表明,胭脂虫在梨果仙人掌、朱耳掌及缩刺仙人掌上均能寄生,但以梨果仙人掌最好;从秘鲁引进的梨果仙人掌及云南禄丰的梨果仙人掌上胭脂虫生长较好;少刺型的梨果仙人掌上胭脂虫生长比多刺型梨果仙人掌好;仙人掌的表皮越厚,胭脂虫的生长越差,而胭脂虫的寄生能刺激仙人掌维管束的发育;仙人掌中蛋白质、水分含量对胭脂虫的生长具有显著影响。更多还原

【Abstract】 The cochineal(Dactylopius confusus) were cultured on cacti collected from ten different counties and the anatomical structure and nutritional components of cacti were analyzed to study the relationship between cochineal and cacti.The results showed that cochineal could host on Opuntia ficus-indica, Opuntia tuna, and Opuntia stricta,but it grew best on Opuntia ficus-indica,and in the species Opuntia ficus-indica,cochineal grew on cacti that imported from Peru and native cacti in Lufeng County of Yunnan Province were better than that of growing on other cacti, and the cochineal grew on spineless cacti were better than that of growing on spinous cacti. The thicker the epiderm of cacti, the worse the cochineal grew. The cochineal could stimulate development of vascular bundle of cacti. Protein and water content of cacti had significant influence to cochineal growth.更多还原
