  1. Twenty insects were used in each experiment. Insects in each section were counted 30 min after introducing each extract. Each data point represents the mean of five replicates. The means followed by the similar letters in each column and each raw are not significantly different (p < 0.05) according to Tukey’s mean comparison test
