Resistance mechanisms of a strain (PRAIAS) of northern house mosquito, Culex pipiens L., collected in Portugal in 1993, and highly resistant to organophosphates and carbamates, were investigated by comparing the resistance characteristics to 3 organophosphorous (temephos, chlorpyrifos, malathion) and 1 carbamate (propoxur) insecticides in the presence or absence of synergists; and by determining the possible occurrence of overproduced esterases or insensitive acetylcholinesterase (AChE).

Insensitive acetylcholinesterase (AceR) and five over-produced esterases (A1, A2 and B2, and A4 and B4) involved in detoxification are responsible for resistance to organophosphorous insecticides (OPs) in Culex pipiens L. from the Rhone-Alpes region, where C. pipiens control is mainly accomplished with the OPs temephos and chlorpyrifos using 0.15 mg/liter doses.

The assay for major enzyme-based resistance mechanisms was done in a microtiter plate to detect elevated non-specific esterases, monooxygenase, and insensitive acetylcholinesterase in the temephos-selected and non-selected groups.

The results of bioassays showed low levels of resistance to fention, malathion and deltametrine, moderate levels of resistance to temephos, metyl-pirimifos and cipermetrine and high levels of resistance to chlorpirifios.
In accordance with the high frequency values observed in each of the mechanisms, it was proved that esterases and glutathione-S-transferase were involved in the insecticide resistance but acetylcholinesterases were not.

Biochemical tests showed high frequencies of esterase and glutathione-S-transferase activity; however, the frequency of altered acetylcholinesterase mechanism was low.
Eight Latin American strains of Aedes aegypti were evaluated for resistance to 6 organophosphates (temephos, malathion, fenthion, pirimiphos-methyl, fenitrothion, and chlorpirifos) and 4 pyrethroids (deltamethrin, lambdacyhalothrin, betacypermethrin, and cyfluthrin) under laboratory conditions.

For temephos, ratios ranged from 3 to 18 and from 1 to 2, respectively.
Cross resistance to organophosphates and carbamates was caused by an insensitive acetylcholinesterase allele (AceR).

Resistance to the organophosphates temephos and chlorpyrifos, the carbamate propoxur, the pyrethroid permethrin, and the organochloride DDT was investigated in Tunisian populations of Culex pipiens pipiens (L.) collected between 1990 and 1996.
To better understand the factors influencing the distribution of resistance in Tunisia, the polymorphism of genes involved in organophosphate resistance (i.e., over-produced esterases and insensitive acetylcholinesterase) was investigated in relation to the genetic structure of populations studied by analyzing the electrophoretic polymorphism of "neutral" genes.

8723267 Wirth MC, Georghiou GP: Organophosphate resistance in Culex pipiens from Cyprus. J Am Mosq Control Assoc. 1996 Mar;12(1):112-8.

All population samples generally revealed organophosphate resistance to malathion, temephos, chlorpyrifos, fenthion, dichlorvos, and pirimiphos methyl, in decreasing order of magnitude.
Resistance was associated with the presence of 5 different overproduced esterases (esterases A1, A2, A5, B2, and B5) as well as an insensitive form of acetylcholinesterase.

15311465 Corbel V, Duchon S, Zaim M, Hougard JM: Dinotefuran: a potential neonicotinoid insecticide against resistant mosquitoes. J Med Entomol. 2004 Jul;41(4):712-7.

The results showed that dinotefuran was less toxic than most of the commonly used insecticides (e.g., deltamethrin, carbosulfan, and temephos) against the susceptible mosquitoes tested (between 6- and 100-fold at the LD50 level).
More interestingly, the carbamate-resistant strain of Cx. quinquefasciatus was significantly more affected by dinotefuran than the susceptible strain (RR = 0.70), probably because the insensitive acetylcholinesterase is less efficient to degrade nicotinic substrates than normal acetylcholinesterase.

Microplate assays were performed to measure levels of beta esterase, acetylcholinesterase, insensitive acetylcholinesterase, oxidases, and glutathione-S-transferase enzymes.
The Qalubiya larval population was susceptible only to malathion, whereas Sharkiya larvae were susceptible to malathion, temephos, and chlorpyrifos.
