Acaricidal, insecticidal, and larvicidal efficacy of fruit peel aqueous extract of Annona squamosa and its compounds against blood-feeding parasites.

Plant products may be alternative sources of parasitic control agents, since they constitute a rich source of bioactive compounds that are eco-friendly and nontoxic products. The plant extracts are good and safe alternatives due to their low toxicity to mammals and easy biodegradability. In the present study, fruit peel aqueous extract of Annona squamosa (Annonaceae) extracted by immersion method exhibited adulticidal activity against Haemaphysalis bispinosa (Acarina: Ixodidae) and the hematophagous fly, Hippobosca maculata (Diptera: Hippoboscidae), and larvicidal activity against the cattle tick Rhipicephalus (Boophilus) microplus (Acari: Ixodidae), Anopheles subpictus, and Culex quinquefasciatus (Diptera: Culicidae).
