Spinosad resistance in the housefly, Musca domestica, is due to a recessive factor on autosome 1
Spinosad is a new and highly promising insecticide with efficacy against a wide range of insects, including houseflies. Selection of the field collected houseflies produced a highly spinosad resistant (>150fold) strain of housefly following 10 generations of selection. Spinosad resistance was a recessive trait linked to autosome 1 which could not be overcome with the insecticide synergists pipe...
متن کاملDetermination of Glutathione S-Transferase e2 Region (GSTe2) in DDT Susceptible and Resistant Anopheles stephensi Populations: Significance and Application of Nucleotide and Amino Acid Comparison
Glutathione S-transferases (GSTs) are a major family of detoxification enzymes which possess a wide range of substrate specificities. Interest in insect GSTs has primarily focused on their role in insecticide resistance. In this study, following World Health Organization (WHO) routine susceptibility test, DNA was extracted from specimens of Anopheles stephensi collected from the Kazeroon distri...
متن کاملSex-limited Inheritance and Abnormal Sex Ratio in Strains of the Housefly.
M A L E S of the housefly (Musca domestica L.) causing sex-limited inheritance of the mutants on the second chromosome have frequently been observed in strains of North American origin (SULLIVAN 1958, 1961; MILANI and FRANCO 1959; HIROYOSHI 1960, 1961). TSUKAMOTO, BABA and HIRAGA (1961) also found similar males in a strain from Japan. When those males were crossed to females carrying recessive ...
متن کاملIdentification and characterization of mutations in housefly (Musca domestica) acetylcholinesterase involved in insecticide resistance.
Acetylcholinesterase (AChE) insensitive to organophosphate and carbamate insecticides has been identified as a major resistance mechanism in numerous arthropod species. However, the associated genetic changes have been reported in the AChE genes from only three insect species; their role in conferring insecticide insensitivity has been confirmed, using functional expression, only for those in D...
متن کاملBiochemistry of Pyrethroid Resistance in German Cockroach (Dictyoptera, Blatellidae) from Hospitals of Sari, Iran
The German cockroach is an important household insect pest mechanically involved in transmission of a variety of diseases to humans. Different classes of insecticides have extensively been used for its control leading to insecticide resistance development. Hence, for an optimal control of this pest, the status and underlying mechanisms of insecticide resistance should be studied in this group o...
