Fig 4. Sh.463 yeast IRP induces A. aegypti larval death.
A. aegypti larval consumption of inactivated dried Sh.463 yeast IRP tablets induced significant larval mortality in laboratory (A) and outdoor semi-field (C) larvicide trials. In panels A and C, data are represented as mean percentage mortality; error bars represent SEM, and *** = P<0.001 in comparison to control yeast IRP-treated larvae. B. Consumption of inactivated dried Sh.463 yeast larvicide tablets induced larval mortality in the fourth instar (L4, days 4–6; compare to larvae fed with control yeast IRP that survived and pupariated). D. A dose-response curve depicting the dosage of Sh.463 yeast vs. the percentage mortality of A. aegypti larvae is shown; LD50 = 34 mg.
