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)。
From Dec. 1989 to Nov. 1990, a survey of seasonality of cockroach density was carried out in the indoor trapping box method in Shantou Port Area. A total of 1,440 cases of trapping boxes and 92 cases of cockroaches were caught in a year with a positive rate of 6.39%. A total of 242 cockroaches were trapped, with a total density of 0.17 per box. The density in spring and early summer was lower, and the density was highest in September and October, then decreased rapidly. The growth and decline of cockroach density are closely related to the temperature (r = 0.756, t_r = 4.846, p <0.001).
