Abstract

Synergistic effect of aloe essential oil on 150 g/L indoxacarb in the control of Spodoptera frugiperda.

Abstract

Purpose: To evaluate the synergistic effect of aloe essential oil on indoxacarb in the control of Spodoptera frugiperda and provide theoretical basis for the control of S. frugiperda. Methods: The effect of physical properties, indoor toxicity and field control effect with adding 0.05% aloe essential oil were determined by surface tension, expanded diameter, maximum retention, indoor toxicity and field control effect. Results: After added aloe essential oil, the surface tension reduced from 51.30-67.57 mN/m to 34.43-51.60 mN/m; the expanded diameter increased from 1.33-1.98 mm to 1.69-2.93 mm; maximum retention increased from 2.86-3.25 mg/cm2 to 3.34- 4.65 mg/cm2; the synergistic ratio of indoor toxicity for indoxacarb to control S. frugiperda between 7.20%-19.61%, and field control effect between 3.82%-26.93%. Conclusion: The aloe essential oil had a good synergistic effect on the control of S. frugiperda by reducing the surface tension, increasing the expanded diameter and retention.
