A comparative analysis of beta-cypermethrin nanoemulsion and traditional emulsion dosages on enzyme activities in Blattella germanica.

To compare the impact of two pesticide dose forms on Blattella germanica (B. germanica)resistance enzymes.The micro-drop technique was utilized on subcultured B. germanica, and the metabolic enzyme activity was assessed.Using spectrophotometry, the relative enzyme activities of B.germanica were determined.Profile analysis was used to compare the enzyme activities of beta-cypermethrin in both nanoemulsion and traditional emulsion forms.Findings: The suppression percentages of the acetylcholinesterase enzyme (AchE), GST, and P450-O demethylases across different pesticide formulations were analyzed using regression equations, yielding F = 31.18, P < 0.001; F = 9.18, P < 0.001; and F = 4.58, P < 0.02.

Conclusion

The suppression of AchE, GST, and P450-O demethylase by beta-cypermethrin nanoemulsion was more significant compared to the beta-cypermethrin emulsifiable concentrate.The study concluded that beta-cypermethrin nanoemulsion had a significant impact on insect detoxifying enzymes compared to beta-cypermethrin emulsifiable concentrate due to their numerous advantages.
