There was a significant interaction effect between
stage of ripeness and mango variety in the total duration
of visits by female flies (ANOVA: F2,114 = 3.641,
P = 0.029), and so results for each variety were analyzed
separately. For variety Namdorkmai, the total duration
of visits differed significantly with ripening stage (ANOVA:
F2,57 = 3.823, P = 0.028).
