Table 2. Occupancy and insecticide efficacy (when occupancy was significantly different from the control) of fruits by Pezothrips kellyanus in 2 orchards located in Alzira and Tavernes.

		Day −1	Day 2		Day 7		Day 14	Day 21	Day 28
Data presented are mean % ± SE. Means followed by different lowercase letters within a column and location are significantly different (1-way ANOVA followed by Tukey post hoc tests, P <0.05).
