Comparison of egg hatchability, larval-to-pupal viability, and daily adult survivorship between homozygous transgenic and nontransgenic Anopheles stephensi mosquitoes

Mosquito line	Replicate	Egg hatchability (%)a	Larval-to-pupal viabilityb	Adult survivorshipb,c
Nontransgenic	1	76.9 (n = 104)	0.97 (n = 70)	0.93 (n = 200)
	2	79.1 (n = 91)	0.98 (n = 70)	0.93 (n = 200)
Transgenic VD9	1	62.1 (n = 103)	0.97 (n = 70)	0.92 (n = 200)
	2	81.7 (n = 71)	0.99 (n = 70)	0.92 (n = 200)
Transgenic VD35	1	80.3 (n = 76)	0.96 (n = 70)	0.88 (n = 200)
	2	74.5 (n = 94)	0.99 (n = 70)	0.89 (n = 200)
Transgenic VD26	1	75.7 (n = 74)	0.99 (n = 70)	0.89 (n = 200)
	2	70.9 (n = 86)	0.99 (n = 70)	0.91 (n = 200)

^aThe number of total eggs for each experiment is given in parenthesis. No significant difference was detected for egg hatchability (P > 0.05 between nontransgenic and all transgenic mosquitoes).

^bThe number of individuals is given in parenthesis. No significant difference was detected for larval-to-pupal viability (P > 0.05 between nontransgenic and transgenic mosquitoes).

^c

The following equation, based on the log-linear reduction of survivorship, was used to determine daily adult survivorship:

$$u_j={\mathrm{e}}^{({\text{log}}_{\mathrm{e}}(u_j^{\prime })/a_{t+1}-at),}$$

where ($u_j^{\prime }$) is the proportion surviving at the termination of the experiment of each genotype and a_t+1 − a_t is the observation period.
