Abstract:

 Description of the subject: Presently, biopesticides are gaining more and more attention from researchers as an alternative to persistent chemical pesticides.

Objective: The insecticidal activity of leaves extracts from Castor (Ricinus communis L.)  was evaluated against green rose aphids Macrosiphum rosae L. affecting the propagation of ornamental plants.

Methods : The biological extracts of the Castor, namely the aqueous extract, the ethanolic extract, the methanolic extract, and the acetonic extract were obtained by extraction with an appropriate solvent. The functional groups of the biomolecules have been determined by spectroscopy. The polyphenols are assayed by spectrophotometry according to the Folin-Ciocalteu method. The toxicity tests against aphid larvae were carried out under laboratory conditions. 

Results : The highest yield was obtained from the aqueous extract (31 ± 0.69%). Analysis by spectrophotometry indicates that the acetonic extract is the richest in polyphenols (151.66 ± 0.85 mg EGA / g). The bioinsecticidal effect shows that the acetonic extract is the most effective against Macrosiphum rosae L. with a mortality rate of 93.33 ± 6.69% after 48 h of exposure and of 100% after 96 h of contact. The LC50 and LT50 values are 0.62 mg/ml and 19.19h, respectively. 

Conclusion : The present study shows the effectiveness of plant extracts, in particular Ricinus communis L. in controlling the green rose aphid Macrosiphum rosae L. This will allow farmers to control pests with minimal negative impact on the environment.
