[Genes, controlling the response of the juvenile hormone degradation system to stress in the Drosophila virilis imago, linked to chromosome 6].

Chromosome localization of the gene controlling the stress response of DFP-sensitive juvenile hormone (JH) esterase in females of Drosophila virilis was conducted. Line 160 of D. virilis carrying recessive markers on all chromosomes was used as a tester. Mature females of line 160 were shown to exhibit a high level of JH hydrolysis; these flies responded to stress by a sharp decrease in JH hydrolysis. Flies from line 147 lacked this response. Thus, mature females of lines 160 and 147 had different levels of JH hydrolysis under heat stress. F2 hybrids that inherited one chromosome pair from flies of line 147 and the remaining chromosomes, from flies of line 147 were analyzed. This analysis showed that the D. virilis gene controlling the stress response of the JH degradation system is linked with chromosome 6.
