Insecticidal potential of physic nut fruits of different stages of maturation on Myzus persicae (Hemiptera: Aphididae)

ABSTRACT Jatropha curcas L. (Euphorbiaceae) is a plant species widely present in tropical and subtropical regions that have been studied mainly for its potential for biofuel production; it is also a plant known for its toxic substances. To explore its use as an insecticide, we studied the effect of...

(Euphorbiaceae) is a plant species widely present in tropical and subtropical regions that have been studied mainly for its potential for biofuel production; it is also a plant known for its toxic substances. To explore its use as an insecticide, we studied the effect of the seed extract from green fruit and the seed oils from the mature and dried fruit of J. curcas on the green aphid Myzus persicae (Hemiptera: Aphididae). Seven concentrations of extracts and oils of different maturation stages of fruits were used and sprayed with the Potter Spray Tower on cabbage leaves containing 10 individuals of M. persicae. Ten repetitions for each concentration were carried out at each stage of maturation (green, ripe, and dry), and the evaluation of the mortality of individuals occurred for a period of 72 hours. The maturation stage of J. curcas, as well as the concentration and time after the application, influenced the mortality of M. persicae. The best results were obtained 48h after applying the dried fruit oil at 2.5% and 72 hours after the application of dry and ripe fruit oil at 2.5%.info:eu-repo/semantics/openAccessUniversidad de Tarapacá.
