【摘要】 本文通过对温带臭虫生活史中各龄若虫及成虫形态的进一步描述，首次提出臭虫度量的长度随虫龄的成熟而逐步增大，身长与体宽之比基本保持在１：１．８左右，前胸宽及前胸长之比在３：１左右；除一龄若虫外，其基节基缘毛丛的数量，每增加一龄，其毛丛根数也增加一根，即ｎ＋１，这在臭虫形态分类及对臭虫的进一步研究和防治有首重要的意义。更多还原

【Abstract】 This paper deals with morphological description of the nymph and adult of Cimex lectularius.Its length gradually increases with maturation of the different stages.The proportion of length and width is atabout 1:1.8.The length and width of prothorax is at about 1:3.The number of coxal marginal setae increaseone as the nymph grows up with one instar.i,c,n+1.except the frist instar nymph.This observation of Cimexlectularius is made for the frist time.These results have great significance in the study of classification andcontrol of the bedbug.更多还原
