The results are following:1 QTL mapping for resistance to Verticillium wilt in G.barbadenseA highly tolerant to Verticillium wilt G.barbadense var.Hai7124 and a highly sensitive to Verticillium wilt G.hirsutum var.Junmian 1 were crossed and F_1 seeds produced self-pollinated F_2 progeny which comprised 128 individuals and BC_1 was produced from a cross between(Hai7124×Junmian 1)×Junmian 1.The BC_1F_1 individuals were self-pollinated to produce a BC_1S_2 population,resulting in 96 families of BC_1S_2.A genetic map included 36 linkage groups with an average distance of 7.29 cM between markers and covered 2726.89 cM was constructed using F_2 population.

Using a long-term reared housefly population which is very susceptible to pyrethroid insecticides as the susceptible strain, a population collected in 1993 in Shanghai and has been treaded by cyhalothrin as the resistant strain, we bioassayed their susceptibility to organophosphorus, carbamate, pyrethroid and organehloride insecticides. We also investigated the role of metabolic enzymes, i. e. esterase, GST, MFO and of target enzymes, i. e. AChE and 〓-ATPase in resistance to insecticides. Cyhalothrin resistance inheritance, the co-toxicity coefficient of cyhalothrin and methylene dithiocyanate was also studied. The insecticides resistance in adults and larvae of houseflies was compared and the mechanism of resistance differences between adults and larvae was discussed.
