Abstract
Aphids are visitors to the majority of plants. These insects multiply rapidly and they secrete lots of reduces. They cause huge direct and indirect damages especially to vegetables that are used fresh, where pesticides cannot be used. Experiments carried out with some plant extracts on Aphis fabae showed that these extracts were effective in controlling aphid multiplication without the use of chemicals. The percentage of aphid mortality reached 90% when plants were treated with extracts of Cyclamen persicum, Styrax officinalis and Smilax aspera. A decrease in the number of nymphs after treatment with Carex hispida and S. officinalis extracts was noticed. Additional negative effects were recorded on aphid females.
