| Abstract | ||
| The results of studying the biological effect of water and coholic leaf extracts of piper and tomato plant on larvae and adults of Colorado potato beetle showed a superior and significant effect of water leaf extract of piper on mean percentage of larvae mortality which reached 73.33% at 8% concentration, while water leaf extract of tomato revealed a significant effect on mean mortality percentage on adult of CPB which reached 46.66% at 8% conc. The alcoholic leaf extract of piper exhibited a good repellency effect on larva and adults of the insect in comparison with leaf water extract. While the water leaf extract of tomato produced a highest repellency percentage on larva and adult reached 36.67 and 56.67% respectively . | ||
