Acetylcholinesterase (A), alpha carboxylesterase (B), beta carboxylesterase (C). There is no statistically significant difference between values that follow the same letter (one-way ANOVA), as shown by the Tukey test at p = 0.05. Notes: the mid-gut tissues of larvae were stained with ehrlich’s haematoxylin and viewed under a light microscope at ×100 magnification.
