大气苯酚对蓖麻蚕的影响及其对策

Effects of airphenol on the castor silkworm(Attacus ricini)and its countermeasures

  • 摘要: 蓖麻接触15μl/L大气苯酚2~10h后叶片出现伤斑、失绿、枯焦卷曲等受害症状,接触6h后株高、条重、产叶量以及叶绿素、粗蛋白和可溶性糖含量分别下降9.9%、11.8%、9.5%、34.7%、3.8%和42.8%。全龄蓖麻蚕接触1μl/L大气苯酚或食下苯酚含量7~21mg/kg的污染叶后均影响其虫蛹率、产卵量及孵化率;接触8μl/L以上的大气苯酚或食下苯酚含量45~70mg/kg的污染叶后蚕生长发育变慢,生命力和生殖能力下降,茧丝性状也明显不良。大气苯酚在这些方面的影响比苯酚污染叶大,蓖麻蚕对大气苯酚的抵抗力随龄期增大而显著增强。用5%石灰水浸渍苯酚污染叶后喂蚕,或将苯酚污染叶与非污染叶交替喂蚕,可减轻苯酚对蚕的毒害。

     

    Abstract: The castor plant leaf lost green, appeared scars,withered up and rolled up after being treated with 15μl/L air-phenol for 2~10h. The plant height,twig weight and output dropped by 9.9%,11.8% and 9.5% respectively, and the contents of chlorophyll, protein and dissolvable sugar for the leaf also dropped by 34.7%,3.8% and 42.8%, after being treated with 15μl/L air-phenol for 6h. The castor silkworm contacted 1μl/L air-phenol or ate castor leaf that contained 7~21mg/kg phenol during their larval stage, thus the larva-pupa rate,amount of laid eggs and hatchability dropped. When the worm contacted large than 8μl/L air-phenol or ate castor leaf that contained 45~70mg/kg phenol during their larval stage,it became slow in growth and development, bad in properties of cocoon and silk, and dropped in reproduction rate. The effects of the air-phenol were more serious than those of the plant-phenol. The resistance of castor silkworm to phenol increased with the larva growth.The toxicity of plant-phenol decreased, when the phenol-polluted leaf was treated with 5% limewater or the polluted leaf and normal leaf was feed alternately to the worm.
