Insensibility of larvae with different chromosomal inversions to the toxins of Bacillus thuringiensis subsp. israelensis (Bti) was examined. It has been shown that larvae with inversion combinations XL0(XL1)2R0-3R0-3L0 had greater variability after treatment with Bti than larvae with inversions XL1(XL2)2R1-3R1-3L1(3L0). The former inversion combinations were previously shown to dominate in the south of the species area and to be supported by K-selection. The latter inversion combinations form "northest" karyotypes and are supported by r-selection. It is obvious that genetic effects of treatments with Bti depend on the population's structure and the directions of natural selection. The decrease in the level of heterozygotes after treatment of larvae with Bti reflects destruction of the system of genetic homeostasis in the natural populations of A. messeae.
研究了具有不同染色体倒位的幼虫对苏云金芽孢杆菌以色列亚种（Bti）毒素的不敏感性。结果表明，与具有倒位XL1(XL2)2R1-3R1-3L1(3L0)的幼虫相比，具有倒位组合XL0(XL1)2R0-3R0-3L0的幼虫在用Bti处理后的变异性更大。先前已表明，前一种倒位组合在该物种分布区域的南部占主导地位，并受到K选择的支持。后一种倒位组合形成“最北”核型，并受到r选择的支持。显然，Bti处理的遗传效应取决于种群结构和自然选择方向。用Bti处理幼虫后杂合子水平的降低反映了梅氏按蚊自然种群中遗传稳态系统的破坏。
