We determined the resistance of 2 Blattella germanica strains collected in 2 municipalities of City of Havana--Playa (P) and Centro Habana (CH)--to six insecticides: malathion, pyrimiphos-methyl, propoxur, cipermetrine, deltametrine, and lambda cialotrine. The P strain showed resistance only to deltametrine (FR = 80); the CH strain was susceptible to propoxur and lambda cialotrine and resistant to malathion (FR = 12), pyrimiphosmethyl (FR = 13), cipermetrine (FR = 16), and deltametrine (FR = 100). Gene frequency of increased esterases and of the modified acetylcholinesterase was determined in the 2 strains. The values of increased esterases in the two collected strains were: P = 0.90; and CH = 0.91. Values of the modified acetylcholinesterase in the two strains were: P = 0.47; and CH = 0.12.
我们测定了从哈瓦那市两个行政区——普拉亚（P）和哈瓦那市中心（CH）采集的2个德国小蠊品系对六种杀虫剂的抗性，这六种杀虫剂分别为：马拉硫磷、甲基嘧啶磷、残杀威、氯氰菊酯、溴氰菊酯和高效氯氰菊酯。P品系仅对溴氰菊酯表现出抗性（抗性系数=80）；CH品系对残杀威和高效氯氰菊酯敏感，而对马拉硫磷（抗性系数=12）、甲基嘧啶磷（抗性系数=13）、氯氰菊酯（抗性系数=16）和溴氰菊酯（抗性系数=100）具有抗性。我们还测定了这2个品系中酯酶增加和乙酰胆碱酯酶变异的基因频率。两个采集品系中酯酶增加的值分别为：P=0.90；CH=0.91。两个品系中变异乙酰胆碱酯酶的值分别为：P=0.47；CH=0.12。
