Abstract

plant extracts using for pest control programs is considered as an alternative control method to decrease synthetic pesticides. The efficacy of petroleum ether and water extracts obtained of I. carnea plant, Convolvulaceae on T. urticae was evaluated. The sprayed leaf disk method was carried out to determine the effect of the plant extract on eggs and adult females under laboratory conditions at concentrations, 5%, 10%, 25% and 50 % were experimented. Mortality % percentages were recorded after 1, 3 and 5 days from treatment. The highest death rates of T. urticae adults were found at 50% concentration recording 82.50 % and 35.00% for petroleum ether and water of Ipomoea carnea extracts, respectively. Both extracts have poor toxic effect to eggs compared with adult females. Both extracts showed superiority in repellency to T. urticae, whereas repellency was decreased gradually as well as time elapsed after treatment. T. urticae females preferred to settle, deposit eggs and feed on the untreated leaves of the disc . The majority or mdinduaes refused to settle on the treated part especially in the high concentrations. Both solvent extracts decreased the female longevity and fecundity. of T. urticae. As a consequence, of Ipomoea carnea are thought to be used as an alternative material to control the two-spotted spider mites.
