The present invention provides a method for suppressing propagation of insects by attracting female insects to mate with a genetically modified mosquito, and the method comprises the following steps. First, a male insect is ground so as to prepare a homogeneous solution. An odor of the homogeneous solution is transferred to the genetically modified insect, and the genetically modified minsect is then released to an environment for attracting the female insect.本發明提供一種昆蟲繁衍的抑制方法,用以誘引雌性昆蟲與基因改造昆蟲交配,且前述方法包含下列步驟。首先,將雄性昆蟲磨碎以製得均質液。接著,將均質液之氣味移轉至基因改造昆蟲上,再將基因改造昆蟲放置於一環境中以誘引雌性昆蟲。S202~S206‧‧‧步驟
