【摘要】 本文报告用亚致死量的二氯苯醚菊酯处理淡色库蚊幼虫后对其羽化成蚊体大小及其体大小与吸血关系的实验研究。结果表明,亚致死量的二氯苯醚菊酯处理淡色库蚊幼虫对成蚊体大小具有明显的影响,随着用药浓度增加成虫翅长相应缩短,成蚊体大小与吸血率高低也有明显的关系,即小体蚊吸血率比大体蚊为高。更多还原

【Abstract】 This paper presents the experimental studies on the effects of suble- thal dosage of permethrin on the adult size(wing length) of Cx.pipiens pallens and the relationship of the adult size to blood feeding during Aug.1990 to Jan.1991.The results showed that the adult sizes of Cx.pipie- ns pallens were affected after the mosquitoes were exposed as fourth ins- tar larvae to the sublethal dosages of permethrin,and there were some relationships of the adult size to the blood feeding of the mosquitoes tr- eated by permethrin,e.g.the percentages of blood feeding in the smaller adults were higher than in the larger adults.更多还原
