Table 2. Comparison of Fungal Development Index (FDI) for conidial treatments of Paecilomyces fumosoroseus Trinidadian strains T, T10, and T11 infecting fourth-instar nymphs of Trialeurodes vaporariorum on a glass slide placed inside a PDA Petri dish plate at 25 ± 0.5 °C for 8 days with a 24:0 and 16:8 hour L:D photoperiod at ~100% RH.
