Rarefaction curves of the OTU number in a 97% similarity boxplot for each sample. T1, Br1 and m1 are shorts for the midgut samples from field-caught population, deltamethrin-resistant population and deltamethrin-susceptible population of Plutella xylostella, from field-caught population, deltamethrin-resistant population and deltamethrin-susceptible population, respectively.
