Toxic baits, widely used against insect pests, are being successfully used to control mosquito vectors. In the present study, basic aspects for Attractive Toxic Sugar Baits (ATSBs) use as a control tool against Aedes aegypti including insecticide dosage, bait composition and plant application under laboratory conditions were evaluated. The Lethal Concentrations (LC 50 and 90) of boric acid (insecticide) Ae. aegypti engorgement and mortality were determined using ATSBs prepared using fruits (guava, mango and cupuaçu) and offered to mosquitoes on cotton discs and also sprayed on a Kalanchoe blossfeldiana plant. LCs of Ae. aegypti males and females did not differ significantly and varied from 0.53 to 2.46%, decreasing from 24 to 48 hours. No significant difference in the proportion of engorged male mosquitoes in ATSB (0.60) and Attractive Sugar Bait (ASB) (0.65) was found, but females engorged more on ASB (control bait) (0.80) compared to ATSBs (0.67). General mortality rate of mosquitoes in ATSB and ASB were 0.81 and 0.10 for males, respectively; 0.61 and 0.12 for females, respectively. Fruit composition affected neither engorgement nor mortality. ATSB applied on plants caused the mortality of males and females ranging from 0.75-0.87 while mortality on ASB sprayed plants varied from 0.07-0.14. Different common fruit juices and a low toxic oral insecticide are readily accepted, engorged and causes a high mortality both males and females Ae. aegypti using ATSBs. Moreover, the use of a common indoor plant in the region sprayed with ATSB under laboratory conditions leads to significant mosquito mortality.
