Repellency and toxicity of three Impatiens species (Balsaminaceae) extracts on Myzus persicae Sulzer (Homoptera: Aphididae)

Original language description

The extracts of Impatiens noli-tangere, I. parviflora and /. glandulifera (Balsaminaceae) were evaluated for their effect on green peach aphid (Myzus perssicae), an important insect pest of many plants. All the extracts showed insecticidal and repellentactivity. After 24 h of exposure, the most active extract was Impatiens parviflora with 99.7 and 90.0 % mortality at 0.5 and 0.1 % concentrations, respectively, and with highly percent repellency (90-100%) at different times. The extract of/, parvifloracontained tryptophan (2.13 mg/g); 2-methoxy-1,4-naphthoquinone (0.02 mg/g), total flavone (7.64 mg/g) and total derivatives of caffeic acid (15.60 mg/g).
