CDC bottle bioassay mortalities for Ae. albopictus populations tested against deltamethrin (pyrethroid) and malathion (OP)
| Population | Deltamethrin 10 µg/ml | Malathion 50 µg/ml | ||||
|---|---|---|---|---|---|---|
| n1 | Mortality (%) (95% CI) | Status | n2 | Mortality (%) (95% CI) | Status | |
| A. Stefanos-ATT | 75 | 100 (–) | S | 79 | 55.70 (28.55–82.85) | R |
| Patras | 70 | 100 (–) | S | 83 | 91.4 (83.10–99.70) | Ra |
| Kefalonia | 88 | 100 (–) | S | 83 | 55.6 (15.15–96.05) | R |
| Heraklion | 78 | 100 (–) | S | 78 | 55.3 (33.70–76.90) | R |
| Susceptible LC | 70 | 100 (–) | S | 76 | 100 (–) | S |
aPossibility of resistance
Notes: Mortality percentages correspond to the discriminating exposure time DT=30 min for both insecticides [40]. The average values of four insecticide treated replicate bottles are presented. n1 and n2 refer to the total number of female mosquitoes tested against deltamethrin and malathion, respectively
Abbreviations: ATT, Attica region; CI, confidence intervals; LC, laboratory colony; R, resistance; S, susceptibility (according to WHO recommendations for CDC bottle bioassay guidelines, 2010)
