  1. Each data point represents the mean of five replicates. Twenty insects were used in each experiment. Insects in each container were counted 14 h after introducing the test samples (20 g). Means followed by same letters in each column and same letters in each raw are not significantly different (P < 0.05) according to Tukey’s Studentized test
