Acantholippia deserticola essential oil as a natural pesticide against agricultural plagues woolly whitefly [(Aleurothrixus floccosus (Maskell)], chilean false red mite (Brevipalpus chilensis Baker) and two-spotted mite (Tetranychus urticae Koch)

Different concentrations of essential oil obtained from Acantholippia deserticola (Phil.ex F. Phil.) Moldenke were assessed against Chilean agricultural pests like Aleurothrixus floccosus (Maskell), Brevipalpus chilensis Baker, and Tetranychus urticae Koch. The bioassays were carried out under laboratory conditions and both direct and residual applications were done through Potter precision spray tower test. The oil was obtained by steam distillation containing a rich fraction of  and -thujones (88.4%) and it shows marked toxic effects against pests. Indeed, a mortality of 82% and 89% was observed in both B. chilensis and T. urticae after 48 h whereas in A. floccosus over 97% of mortality was seen after 7 days. These results open the possibility to use essential oil from Acantholippia deserticola as natural pesticide

(spa) Se evaluó el efecto a diferentes concentraciones de una solución de aceite esencial de Acantholippia deserticola sobre plagas agrícolas en Chile, tales como Aleurothrixus floccosus(Maskell), Brevipalpus chilensis Baker y Tetranychus urticae Koch. Los bioensayos fueron realizados mediante una torre de Potter en condiciones de laboratorio y las aplicaciones fueron directas y residuales.El aceite se obtuvo por hidrodestilación, el cual contenía una gran cantidad de  and -tuyonas (88.4%), mostrando marcados efectos tóxicos para A. floccosus, con un 97% de mortalidad después de 7 d y, para B. chilensis, y T. urticae, con una mortalidad de 82% y 89% respectivamente, después de 48 h. Estos resultados abren la posibilidad de usar aceite esencial de Acantholippia deserticola como pesticida natural
