Postembryonic development and adult emergence ofCorcyra cephalonica (Stainton) were adversely affected in varying degrees when individuals were reared for the first 2 weeks of larval life or for a similar duration from the sixteenth day of their lives in an environment of eucalyptus oil volatiles. This was, however, not so in the progeny of parents exposed to these volatiles for only 5 min. Exposure of this pest to neem oil volatiles during larval stages for similar periods failed to produce such adverse effects. A marked decline in the reproductive potential, in terms of egg output and egg hatchability, of the moth was observed when the larvae were reared for the first 15 days in the presence of eucalyptus oil volatiles or when the parents were exposed for 5 min to such an environment during adult life. Thus, a "carry over" of the detrimental effect of the volatile(s) of this oil on the reproductive potential of the pyralid was indicated.
在桉油挥发物环境中饲养的个体，幼虫生命的头两周或第十六天起相似时长内，咖啡透翅长蠹（Corcyra cephalonica）的胚胎后发育和成虫出现受到不同程度的不利影响。然而，仅接触这些挥发物 5 分钟的亲代的后代则没有受到这种影响。在幼虫期接触类似时长的印楝油挥发物也未能产生这种不利影响。当幼虫在存在桉油挥发物的情况下饲养头 15 天，或当亲代在成虫期仅接触这种环境 5 分钟时，观察到蛾子的生殖潜力（产卵量和卵孵化率）明显下降。因此，表明这种油的挥发物对鳞翅目昆虫的生殖潜力产生了“延续”的有害影响。
