Using eco-friendly green insecticides for storages pest management: Prangos ferulacea (essential oil and powder) against Callosobruchus maculatus (Col. : Chrysomelidae)

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 ± 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 has acceptable respiratory toxicity to the examined storage pest.
