Table 2 Mean survival rates of Aedes aegypti released into rooms containing black cloths impregnated with fungal conidia using three different carriers

From: Monitoring persistence of the entomopathogenic fungus Metarhizium anisopliae under simulated field conditions with the aim of controlling adult Aedes aegypti (Diptera: Culicidae)

  1. Three fungal treatments were tested: conidia + Tween (T), conidia + vegetable oil (V) and conidia + vegetable oil + isoparaffin (I).
  2. At the end of each time period, the surviving mosquitoes were captured and a new cohort released into the room. Mean survival values followed by the same letter indicate that the results for each treatment were not statistically different when using a one way analysis of variance followed by Tukey’s test (5% probability) to compare the different periods that cloths had been left in the rooms. ND = not determined. Control results for each time period were not significantly different for each repetition (P > 0.01) and were thus pooled and shown as a single mean value for each treatment.
