| Abstract: | The purpose of this study is: study of the activity of insecticides, extracted from the branches and leaves of Rosmarinus officinalis against A.fabae. Three different doses (24h, 48h, 72h) are used for the fight against the pest (black aphid), we found that the fight of A.fabae is positively proportional with the concentrations of the extract as a function of time. The 72-hour concentration seems to be the most effective concentration, after a product use time of 48 hours divided into an observation time of six hours, with a maximum mortality rate of 70%. |
