Development of Deltamethrin-Laced Attractive Toxic Sugar Bait to Control Aedes aegypti (Linnaeus) Population

Table 1

Deltamethrin susceptibility status of the four strains of Aedes aegypti: laboratory strains (AND-Aedes aegypti and AND-Aedes aegypti-DL10) and wild-caught colonized strains (GVD-Delhi and SHD-Delhi) of Aedes aegypti after 24 h exposure to 0.05% deltamethrin-impregnated papers.

Strains	LT50 (min.)	RR LT50 (min.)	LT90 (min.)	RR LT90 (min.)	% Mortality after 24 h
AND-Aedes aegypti	4.43	—	8.85	—	100
AND-Aedes aegypti-DL10	4.76	1.07 (S)	9.98	1.12 (S)	100
Aedes aegypti (GVD-Delhi)	8.78	1.98 (S)	15.99	1.80 (S)	100
Aedes aegypti (SHD-Delhi)	8.38	1.89 (S)	14.91	1.68 (S)	100

LT_{50 or 90}: lethal time for killing 50% or 90% mosquitoes exposed; RR: resistance ratio; S: susceptible, based on the WHO protocol (WHO, 2022).
