Abstract

The objective of this study was to evaluate the insecticidal effect of aqueous extract of castor bean (Ricinus communis) cake for the control of Maconellicoccus hirsutus. The toxicity tests were performed in the laboratory. Subsequently lethal concentrations 50 and 90% (LC50and LC90, respectively) were estimated. Tween80® + distilled water was used as surfactants and solvent respectively. The assay was performed in petri dishes containing a Coffea canephora leaf disc. The spraying was carried out in Torre de Potter spray tower. The extract was toxic to mealybug and the mortality data was adapted to the probit model. Estimates of LC50 and LC90 were 5.32% and 29.30%, respectively. It was concluded that the aqueous extract of R. communis cake is promising for the management of M. hirsutus.
