美洲蟑螂(Periplaneta americana L.)是種很可怕的衛生害蟲,能傳染疾病,汙染環境,雖然近年來環境衛生已改善,但為害廚房、屋室、倉庫甚為嚴重。 早再1932年Collins氏等發現動物能產生特有的性誘引劑(sex attractants),直到1952年Roth氏等肯定美洲蟑螂之Virgin female產生微量性誘引劑,能使雄翅飛翔(7)。1954年應國Warton氏等從Virgin female爬過的濾紙抽出28?g的純誘引劑,對雄蟲產生高度之誘引力。(8, 9) 1963年美國的Jacobson氏等發表其為2,2-dimethyl-3-isopropylidene-cyclopropyl propionate之構造(6),後來被Day氏(1964)所推翻(4),故其真正結構能未知,目前大家只承認其為一種含有酯類的不飽和酮類物質(1)。本文擬報導期性誘引劑分離的結果。 Isolation of the sex pheromone of the female American cockroach,Periplaneta americana L。, has been collected and isolated by a combination of extraction and chromatographic procedures. Progress through these procedures has been followed by bioassay. The sex pheromone has been isolated by gas-liquid chromatography and characterization by infraed spectrometry is proceeding.
