Table 2 Aedes aegypti survival rates following exposure to blastospores at different times after applying the suspensions to the cloths

Drying time	Blastospores 0 h	Blastospores 12 h	Blastospores 24 h	Control
Survival (%) ± SD	8.8 ± 9.97a	61.1 ± 4.32b	81.1 ± 1.61c	82.2 ± 2.36 c

End-point survival rates (% ± SD) and median survival times (S₅₀) of female Ae. aegypti 7 days after exposure to cloths impregnated with ESALQ 818 blastospores at a concentration of 1 × 10⁷ propagules ml⁻¹. The cloths were placed in the pots immediately (0 h), 12 h, or 24 h after applying blastospores to the cloths. Mean survival percentages followed by different letters indicate statistical differences when comparing values using ANOVA followed by Duncan’s post hoc (5% level). Control data for all treatment groups were combined, and a single mean survival rate was calculated
nd not determined
