摘要
1989年12月至1990年11月,在汕头港区室内用诱捕盒法进行了蟑螂密度季节消长调查,全年共布放诱捕盒1440盒次,捕获蟑螂的92盒次,阳性率为6.39％。共诱捕蟑螂242只,总密度为0.17只/盒,春季及初夏密度较低,9月及10月密度最高,以后急速下降。蟑螂密度的消长与气温的高低有密切相关(r=0.756,t_r=4.846,p<0.001)。
The survey of seasonal growth-decline of cockroaches using the lure-box method was carried out in indoor of Shantou port during December J989 to November 1990. 1440 Box -times were placed in the whole year. The positive rate was 6. 39 %. Altogether 242 cockroaches were lured. The general density was 0.17/Box. The density is lower in the Spring and early Summer and that is highest in September and October 1989. After October, the density declined hurriedly. There was a close correlation between the density of cockroach and the temperature (r = 0. 756 t, = 4.846 p<0.001) .
