Bioactividad de Spilanthes acmella (Asteraceae) a Raoiella indica (Acari: Tenuipalpidae) y selectividad al depredador Amblyseius largoensis (Acari: Phytoseiidae)

摘要: The jambu, Spilanthes acmella (Asteraceae), has bioactivity on pests, but little is known of the effect phytophagous mites and its compatibility with predatory mites. red palm mite, Raoiella indica , a severe pest several crops, coconut trees among them. mite Amblyseius largoensis (Acari:Phytoseiidae) found in association R. countries, it can assist control this field. Associated biological control, products that are compatible natural enemies could help pest. Therefore, acaricidal activity S. amella selectivity for predator A. was evaluated using concentration-mortality bioassays ethanolic extract (EE). Additionally, repellent population growth rate were LC 50 8 0. EE highly toxic to did not kill . 80 from estimated indica, untill 48 hours after application, while, at highest concentration, repelled.
