Levels of insecticide resistance to deltamethrin, malathion, and temephos, and associated mechanisms in Aedes aegypti mosquitoes from the Guadeloupe and Saint Martin islands (French West Indies)

Table 5 Resistance status of Ae. aegypti females from Guadeloupe and Saint Martin to deltamethrin

Deltamethrin concentration/time of exposure	Assessed parameters	DH	AB	SF	SXM	ABY	BM
0.06%/1 h	KD rate	0.93	0.94	0.98	1	0.96	0.99
0.06%/1 h	Mortality rate	0.83	0.64	0.79	0.88	0.79	0.90
0.08%/1 h	KD rate	1	0.96	1	1	0.99	1
0.08%/1 h	Mortality rate	0.94	0.93	0.81	0.98	0.85	0.99
0.05%/2 h	KRR50 (ci 95%)	17.7 (16.7–20.5)	28.1 (24.2–34.9)	13.7 (13.0–14.4)	12.4 (12.0–12.8)	8.0 (7.8–8.3)	13.6 (13.1–14.2)

KD rate: rate of knockdown mosquitoes after one hour of exposition, KDT₅₀: time (min) necessary to knock down 50% of mosquitoes
KDT₅₀ were determined using papers impregnated with 0.05 g/100 ml deltamethrin following WHO insecticide testing recommendations, KRR₅₀: ratio between field samples KDT₅₀ and susceptible Bora Bora strain KDT₅₀, DH Deshaies, AB Anse-Bertrand, SF Saint-François, SXM Saint-Martin, ABY Les Abymes, BM Baie-Mahault
