Abstract
Sweetpotato whitefly, Bemisia tabaci (Gennadius), is an important pest of many crops, with an extremely wide host range. Management strategies using natural products, e.g., plant extracts, might be alternatives for control of this pest. Ethanolic extracts of Chenopodium ambrosioides L., Piper nigrum L., Thymus vulgaris L., and Origanum vulgare L., were evaluated. C. ambrosioides ethanolic extract at 6% concentration killed 93%; P. nigrum at 4 and 5% concentrations killed 96 and 98%, respectively; T. vulgaris at 11% concentration killed 94%; and O. vulgare at 12 and 15% concentrations killed 98 and 100% of whiteflies. P. nigrum was most toxic with a lethal concentration 50 (LC50) of 1.6%. All extracts were positive for tannins and flavonoids. P. nigrum was very positive for alkaloids, tannins, and saponins. These spices are inexpensive and easy to cultivate in Mexico and are available as raw material for production of extracts with insecticidal activity. They are harmless to humans and are much u... Resumen. Bemisia tabaci (mosca blanca) (Gennadius) es reconocida como una plaga importante en muchos cultivos y tiene un rango de huéspedes extremadamente amplio. El uso de estrategia de control empleando productos naturales en la forma de extractos vegetales puede ofrecer alternativas para este control de plagas. Se evaluaron los extractos etanólicos de Chenopodium ambrosioides L., Piper nigrum L., Thymus vulgaris L., y Origanum vulgare L., contra la mosca blanca. El extracto etanólico de C. ambrosioides mató el 93% de moscas blanca a una concentración del 6%; P. nigrum a 4 y 5% de concentración llevó a la muerte 96 y 98%, respectivamente; T. vulgaris a una concentración del 11% causó la muerte de 94%; y O. vulgare a 12 y 15% de concentración mató el 98 y 100%. El extracto de P. nigrum fue el más tóxico con una concentración letal 50 (CL50) de 1.60%. Todos los extractos fueron positivos para taninos y flavonoides. En P. nigrum se determinó principalmente la presencia de alcaloides, taninos y saponinas. E...Keywords
