  • 胭脂虫

例句与用法

  • 2 ) while at suitable temperatures , 60 - 80 % relative humidity is suited for cultivating the cochineal insect , and comparing from the size and eggs of the female adults , high relative humidity is more suited for the cultivation of the insect
    2 )在合适的温度条件下， 60 % rh到80 % rh对胭脂虫的培育是适宜的，从雌虫体大小和怀卵量上比较，高湿度更有利于胭脂虫的培育。
  • 3 ) the cochineal insect can develop well when the light is 601ux to 9801ux while the temperature and humidity are at suitable levels . comparing from the population tendency index , the index is larger under weaker light
    3 )在光照对胭脂虫的影响方面，只要有适宜的温湿度条件， 601ux到980lux的光照强度下胭脂虫均能正常发育，从种群趋势指数上看，弱光下胭脂虫的种群趋势指数更大。
  • On the basis of foreign documents , the dissertation firstly describes the morphology , taxonomy , and biological characters of cochineal insects . then , by using artificial climate cases in the lab , according to orthogonal design , 8 lands of combinations of temperature , humidity and light is set , while the temperature has four levels : 15 , 20 , 25 and 30 , and the relative humidity has two levels : 60 % and 80 % , while the light also has two levels : 980 lux and 60 lux . through observations and analysis of hatching percentage , survival percentage of the first instar and during from the second instar to the adult , the population tendency index , generation life cycle , size and eggs of female adult , the development of the cochineal under different conditions is studied
    在收集、整理国外对胭脂虫的研究资料基础上，首先从胭脂虫的形态学、分类学、生物学特性入手，进而在实验室内利用人工气候箱，应用正交设计方法，设计了4种温度、 2种湿度、 2种光照梯度的不同组合，通过测定胭脂虫的孵化率、 1龄若虫的存活率、 2龄若虫至成虫期存活率、种群趋势指数、世代历期、雌成虫的大小、怀卵量等生物学指标，深入研究胭脂虫在这些组合下的生长发育状况，应用数理统计方法，分析出温度、湿度和光照对各项生物学指标的影响，找出胭脂虫适宜的室内培育条件，并为野外胭脂虫的培育提供一定的理论依据。
  • The main conclusions include : 1 ) among the non - biological factors , temperature is the most important factor that influence the development of the cochineal insect , the insect cannot finish life cycle under 15 associated conditions in spite of a few of egg can hatch , while at associated conditions of temperatures 20 , 25 , 30 , the insect can finish life cycle , but comparing from the amount of eggs , generation tendency indexes and the sizes of the female adults , 25 associated conditions are the best
    得出的主要结论包括： 1 )在胭脂虫的生长发育过程中，温度是影响胭脂虫发育的最主要因子，在15的恒温状态下，尽管胭脂虫卵有少量孵化，但不能完成世代，而在20 、 25 、 30的恒温下胭脂虫能正常发育并完成世代。从培育的胭脂虫雌虫体大小、怀卵量及世代倾向等方面比较， 25的温度最有利于胭脂虫的培育。
  • The samples of cactus which is the host of cochineal insects in 10 counties of yunnan and guizhou province are collected and the cochineal female adults are cultivated on them to test the influence of host species to the development of the cochineal . the samples of different cactus are dissected and the anatomical st ructure are compared as well as the nutritional compositions are analyzed to study the relation between the cochineal and its hosts
    采集云南省和贵州省共10个县(市)的胭脂虫寄主仙人掌的不同种和种源，通过放养胭脂虫比较出不同种的仙人掌和地理种源对胭脂虫生长发育的影响，并对仙人掌进行解剖及营养成分分析，比较仙人掌解剖结构及营养成分的差异，初步探索胭脂虫与仙人掌寄主之间的关系。
