“…(1997) reported increased (three‐fold) tolerance of this species to pirimiphos‐methyl, fenitrothion and permethrin in Venezuela. Falcão et al . (1988) found that only 10 mg a.i./m 2 was enough to kill 100% of females exposed to treated filter papers in WHO bioassay kits.…”

Abstract. Phlebotomine sandflies (Diptera: Psychodidae) transmit many zoonotic diseases (arboviruses, bartonelloses and especially leishmaniases) of importance to human health in at least 80 countries. Measures used to control adult sandflies (Lutzomyia and Phlebotomus) include the use of insecticides (mostly pyrethroids) for residual spraying of dwellings and animal shelters, space-spraying, insecticidetreated nets, impregnated dog-collars and personal protection through application of repellents/insecticides to skin or fabrics. Because the breeding-sites of sandflies are generally unknown, control measures that act specifically against immatures are not feasible, although the effectiveness of a few biological and chemical agents has been demonstrated in laboratory evaluations. Reports of insecticide-resistance refer to only three sandfly species (P. papatasi, P. argentipes and S. shorttii) against DDT in one country (India), although there are reports of DDT-tolerance in several countries. Current knowledge of sandfly susceptibility to various insecticides is summarized. Constraints and advantages of different compounds, formulations and delivery methods for sandfly control under different environmental conditions are discussed.

“…The tree obtained shows a similar topology to that using the period gene (Bauzer et al 2002a). Although insecticide resistance has not yet been demonstrated in L. longipalpis there are some indications of its occurrence in this species (Falcão et al 1988, Mazzarri et al 1997. The fragment we isolated may provide a useful molecular marker for the screening of putative insecticide resistance mutations in populations of this vector.…”

“…In many vector species such as Neotropical phlebotomine sand flies, the occurrence of insecticide resistance is still poorly studied. Insecticide resistance has not yet been demonstrated in L. longipalpis but there are some indications of its occurrence in this specie [10, 11]. …”

BackgroundGiven the increase in cases of visceral leishmaniasis in recent years, associated with the socio-economic impact of this disease, as well as the wide distribution of Lutzomyia longipalpis in Brazil and the likelihood that this vector may develop resistance to insecticides used for control, the Ministry of Health considers as crucial the creation of a network in order to study and monitor the resistance of this vector to insecticides used for control. In this sense, this study aimed: 1) to characterize the susceptibility of L. longipalpis from Lapinha Cave (Lagoa Santa, MG - Brazil) to Alfateck SC200 in field bioassays, and 2) to define the susceptibility baseline to alpha-cypermethrin in laboratory bioassays, checking the possibility of using it as susceptibility reference lineage (SRL).FindingsThe field bioassays revealed that the tested population was highly susceptible to alpha-cypermethrin in all time periods with high mortality (~100 %) in all treated surfaces before six months after spraying. In the laboratory bioassays, the studied population presented LD50, LD95 and LD99 to 0.78013, 10.5580 and 31.067 mg/m2, respectively. The slope was 1.454121.ConclusionsThe studied population of L. longipalpis was considered as adequate for SRL according criterion recommended by Pan-American Health Organization and has proven susceptibility to tested insecticide in the field. One cannot rule out the possibility of finding populations of L. longipalpis more susceptible to alpha-cypermethrin; therefore, further research is necessary on other populations with potential use as a SRL.
