Figure 1

Field efficacy of spirotetramat (St) and Isaria fumosorosea (If) formulations against Asian citrus psyllid (ACP) Diaphorina citri (Hemiptera: Psyllidae) in April 2016. Columns represent ACP population means ± standard error (n = 3). Different small and capital letters over bars signify statistical difference respectively among treatments for each observation time (ANOVA; P ≤ 0.05), and overall among treatments (two factor ANOVA; P ≤ 0.05). FD: field-recommended dose; HD: half of field-recommended dose.

Field efficacy of spirotetramat (St) and Isaria fumosorosea (If) formulations against Asian citrus psyllid (ACP) Diaphorina citri (Hemiptera: Psyllidae) in March 2017. Columns represent ACP population means ± standard error (n = 3). Different small and capital letters over bars signify statistical difference respectively among treatments for each observation time (ANOVA; P ≤ 0.05), and overall among treatments (two factor ANOVA; P ≤ 0.05).
