Table 3 Aedes aegypti survival rates following exposure to blastospores formulated in oil at different times after preparation

From: Metarhizium anisopliae blastospores are highly virulent to adult Aedes aegypti, an important arbovirus vector

Treatments Mean survival (%) ± SD S50 (days)
Blastospores + oil 0 h 4 ± 9.75a 3
Blastospores + oil 12 h 8.8 ± 10.6b 3
Blastospores + oil 24 h 11.1 ± 8.37b 3
Blastospores + oil 48 h 28.8 ± 7.9c 4
Control + oil 81.1 ± 2.76d nd
Control (TW) 82.2 ± 2.28d nd
  1. 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, with and without the addition of 20% sunflower oil to the suspensions. Mosquitoes were exposed to the cloths immediately after application of fungi to the cloths (0 h) or 12 h, 24 h, or 48 h later. 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 each oil treatment group (four data sets) were combined, and the single mean survival rate was calculated
