Five field strains of Blattella germanica from different areas of Bulgaria were tested for resistance to DDT. The strain from Sofia-city after 24 hours of exposure was resistant to DDT in terms of mortality by resistant ratio of 3.76 at the LT50 level. Also 5 strains of B. germanica from 3 regions of Bulgaria have been tested to the carbamate insecticide--Propoxur. For the first time in Bulgaria, DDT- and Propoxur-resistant cockroach strains have been found. It is due to female and nymph resistance, while the males are highly susceptible to Propoxur.
对来自保加利亚不同地区的5个德国小蠊野外菌株进行了滴滴涕抗性测试。来自索非亚市的菌株在暴露24小时后，就死亡率而言，在LT50水平上对滴滴涕具有抗性，抗性比率为3.76。还对来自保加利亚3个地区的5个德国小蠊菌株进行了氨基甲酸酯类杀虫剂残杀威的测试。在保加利亚首次发现了对滴滴涕和残杀威具有抗性的蟑螂菌株。这是由于雌虫和若虫具有抗性，而雄虫对残杀威高度敏感。
