Assessing stability of the larvae-derived oviposition stimulant(s). Ae. aegypti oviposition preference to conspecific larval extracts (A) kept at 4 °C for three days and (B) freshly lyophilized, kept at room temperature and reconstituted three days later. Similar experiments performed with fresh extract (C) kept at 4 °C for 30 days and (D) freshly lyophilized extract kept at room temperature for 30 days and reconstituted on the day of the tests. N = 12 for each dataset. Data were arcsine transformed, and after passing the Shapiro-Wilk normality test, each group was compared by using 2-tailed, paired t tests.
