  1. Notes: Testing was performed using Ae. aegypti Rockefeller strain larvae at Instituto Oswaldo Cruz (IOC-Fiocruz), and on Ae. aegypti Liverpool strain at the Uniform Services University (USU) and the University of New Mexico (UNM). Variation in LD values may reflect difference between the two larval strains used. LD values are in mg/l of orange oil. This table is a compilation of all experiments performed at the three sites, with n representing the total number of insects tested at each larval stage. While there were some differences between the LD50 and LD90 values measured in different research institutes, these measurements fall in the same order of magnitude
