概述聚集现象在动物中是常见的,德国小蠊也有聚集性,特别是在休息时,聚集信息素起着重要作用(Brossut 1979,Ishii and Kuwahara 1967)。这种聚集信息素存在于粪便中(Ishii and Kuwahara 1967,1968)。Fuchs和Sann(1981,1985)等人对粪便提取物作了化学分析,鉴定出150种化合物,但均无信息素活性。Persoons和Ritter(1979)指出德国小蠊聚集信息素的化学成分比较复杂,可能是由于几种或多种物质按一定比例混合后共同发生作用,因此,化学结构至今未被阐明。Glaser(1980),Persoons(1979)Rust,(1977a、1977b.等人探讨了用聚集信息素的粗提物进行诱捕防治试验,降低了蜚蠊对化学
Summary Aggregation is common in animals and cockroaches are also aggregated, concentrating pheromone, particularly during rest (Brossut 1979, Ishii and Kuwahara 1967). This aggregated pheromone is found in faeces (Ishii and Kuwahara 1967, 1968). Fuchs and Sann (1981, 1985) et al. Chemically analyzed fecal extracts and identified 150 compounds but none of them had pheromone activity. Persoons and Ritter (1979) pointed out that the chemical composition of the concentrated pheromone of the cockroach Blattella germanica is rather complicated, possibly due to the combined effect of several or more substances in certain proportions. Thus, the chemical structure has not yet been elucidated.
