Insecticidal activity of essential oil and powder of Prangos ferulacea as eco-friendly insecticides against Callosobruchus maculatus (Coleoptera: Chrysomelidae)

Abstract

To promote the use of eco-friendly green pesticides as storage pests, this study was designed to evaluate the insecticidal effects of Prangos ferulacea Lindl. essential oil and powder on Callosobruchus maculatus F in vitro.The LC 50 value of the essential oil was 16.28 μL/L, and the LD 50 value of the powder was equal to 1.6 g/kg food after 72 h. The LT 50 value of the essential oil was 36.623 h for stability and analysis of the probit slope (1.596±0.291), and the logarithm of time and mortality rate were significant (95% CI). The LT 50 value was determined to be 38.72 h for the powder and 50.85 h for the aluminum phosphide tablets; thus, the essential oil had a greater effect on the powder formulation as well as the aluminum phosphide. A comparison of the durability of the treatments revealed that during 24 h, the essential oil with a mortality rate of 80.55 $$\pm$$ 6.10% was significantly superior to the aluminum phosphide tablets (40.50±7.43% at 99% CI).The results of this study revealed that P. ferulacea essential oil exhibits acceptable respiratory toxicity against the examined storage pest.
