Abstract

Resistance to insecticides from various chemical groups was assessed under laboratory conditions, on several strains of German cockroach, Blattella germanica (L.), obtained from populations collected from food facilities in Moscow, Moscow Region (Krasnogorsk, Dmitrov), and Magnitogorsk.. It was established that German cockroaches of all the studied strains had the highest resistance to cypermethrin (92-> 4000×). Resistance to chlorpyrifos was also high (30-50×), only cockroaches from Magnitogorsk were tolerant to this active ingredient (5×). For the first time in Russia, extremely high cockroach resistance to fipronil (23-192×) has been established. In the studied strains of German cockroach, susceptibility or tolerance to neonicotinoids was recorded. Resistance ratios for thiamethoxam were 2.2-10× and for its active metabolite clothianidin were (1.3-9.6×). Mosaic resistance to indoxacarb (3.2-31×) and chlorfenapyr (2.5-60×) was found in different strains of German cockroach. Possible mechanisms of insect multiresistance to insecticides are discussed. Key words: German cockroach, Blattella germanica, resistance, insecticides.

关于多重耐药德国cochachache在俄罗斯的新数据

在实验室条件下，对从莫斯科、莫斯科地区(克拉斯诺戈尔斯克、德米特里罗夫)和马格尼托哥尔斯克的食品设施采集的德国小蠊(Blattella germanica, L.)的几种菌株对不同化学类群杀虫剂的抗性进行了评估。结果表明，所有品系德国蜚蠊对氯氰菊酯的抗性最高(92 ~ > 4000×)。对毒死蜱的抗性也很高(30 ~ 50倍)，只有马格尼托哥尔斯克地区的蟑螂对毒死蜱有抗性(5倍)。在俄罗斯首次发现蟑螂对氟虫腈具有极高的抗药性(23- 192x)。在所研究的德国蜚蠊品系中，记录了对新烟碱类杀虫剂的敏感性和耐受性。噻虫嗪的耐药率为2.2 ~ 10倍，其活性代谢物噻虫胺的耐药率为1.3 ~ 9.6倍。不同品系的德国蜚蠊对茚虫威(3.2 ~ 31倍)和虫螨腈(2.5 ~ 60倍)均有花叶抗性。讨论了昆虫对杀虫剂多重抗性的可能机制。关键词:德国蜚蠊;德国小蠊;抗药性;
