为给防制蟑螂提供科学依据,进行控制或减少有关蟑螂传播疾病的流行机会,曾于一九八四年七月至一九八五年六月在东胜市对蟑螂种群分布、季节消长、栖息与活动场所、夜间活动规律的生态习性进行了调查。对全市四个办事处用ZA型粘蟑纸捕获蟑螂8,595只,其中成虫占56％,若虫占43％,经鉴定只有一种,即德国小蠊Blattella germanica. 对全市11,047户口询687户,阳性率达46.72％,在口询301户阳性中,布放粘蟑纸,粘蟑率达79.10％。并对其侵袭户蟑螂密度进行了对比,其比率高密度为29.86％,中密度为46.18％,低密度为24.15％,呈两头小中间大的状态。对不同行业、活动栖息场所、房屋结构进行了密度对比。以医院、豆腐房、毛纺厂、酒厂、食堂为高。分别依次为100％、50％、50％、50％、37.50％。其栖息活动场所密度以锅台,火炕、橱柜为高,分别占7.02～34.60％,其房屋结构密度,新建房屋占62.17％,旧房占44.62％,楼房占52.56％,平房占47.24％,并对蟑螂今后迁徙、蔓延以及传播某些疾病的可能性加以讨论。
In order to provide a scientific basis for controlling cockroaches and to control or reduce the prevalence of cockroach-borne diseases, the cockroach population in Dongsheng was distributed from July 1984 to June 1985 with seasonal fluctuations, Habitat and activity sites, activities of the law of ecological habits were investigated. Of the city’s four offices, 8,595 cockroaches were caught with ZA sticky cockroach paper, of which 56% were adult and nymphs accounted for 43% of the cockroaches and only one was identified as Blattella germanica. Rate of 46.72%, in an interview with 301 positive, cloth sticky cockroach paper, sticky cockroach rate of 79.10%. The density of cockroach invaders was compared with the ratio of high density of 29.86%, medium density of 46.18%, low density of 24.15%, showing two small middle large state. For different industries, the activities of habitat, housing structure density contrast. To hospitals, tofu room, wool mills, wineries, canteens as high. Respectively, followed by 100%, 50%, 50%, 50%, 37.50%. The density of habitats is in the range of 7.02-34.60% for pots, kangs and cabinets, respectively. The density of housing structures is 62.17% for new houses, 44.62% for old houses, 52.56% for buildings and 47.24% for bungalows. Cockroaches in the future migration, spread and the possibility of transmission of certain diseases to be discussed.
