Insecticidal activity of crude extracts of three spices and commercial botanical pesticide on oriental fruit fly under laboratory conditions

Abstract Background The uses of botanical pesticides in pest management are currently on remarkable increase due to their efficacy, biodegradability, environment-friendly, and availability. Ethanol extracts three spices ( Piper guineense , Aframomum melegueta Zingiber officinale ) commercial pesticide AzaSol (6% azadirachtin) were assessed for contact toxicity, residual effects, potential soil application against pupariating larvae oriental fruit fly Bactrocera dorsalis the laboratory at ambient temperature 27 ± 2 °C relative humidity 75–80%. applied 1:1.5 w/v concentration while cypermethrin was introduced as standard check 5 ml/liter water. Results All treatments very effective B. toxicity affects recording 89.4–100% larval mortality 24 h post-application. Z. had similar effects both 100% post-exposure. showed higher than A. better larvae. most among botanicals reducing adult emergence enhancing (96.7%) treated followed by (83.3%). efficacy comparable cypermethrin. significantly more control soil. Conclusion P. highly promising could be adopted targeting puparia under tree canopies part integrated B . orchards.
