An experimental hut study to quantify the effect of DDT and airborne pyrethroids on entomological parameters of malaria transmission

Table 9 The fecundity of mosquitoes after exposure to mosquito coils and DDT in experimental huts

Treatment	Total mosquitoes that laid eggs/total blood fed mosquitoes	OR [95% CI]	Mean proportion	[95% CI]	z value	p value
Control	202/614	1.00 [0.00 – 2.00]	0.33	[0.28 - 0.37]	-7.36	NA
DDT	19/76	0.68 [-0.32 – 1.41]	0.20	[0.13 - 0.30]	-2.41	0.016
Transfluthrin coils	1/6	0.41 [-0.36 – 3.02]	0.15	[0.02 - 0.61]	-0.94	0.347
Metofluthrin coils	11/34	0.96 [-0.57 – 5.98]	0.24	[0.13 - 0.40]	-1.13	0.258

Legend: Fecundity was measured by determining the proportion of mosquitoes that laid eggs out of those that successfully blood fed. Fecundity was compared between mosquitoes exposed to mosquito coils, DDT and no insecticide inside experimental huts in the semi field system for 16 nights.
CI – Confidence intervals; OR – Odds ratios of the proportion of mosquitoes.
