| Abstract | ||
| Owing to the importance of the Egyptian leek, Allium ampeloprasum L., Dill, Anethum graveolens L. and parsely, petroselinum crispum (Mill.) as an important part of medicinal properties and fresh eating. Therefore, the present work was carried out to study the survey, population fluctuation of injured pests and some related climatic factors (temperature and relative humidity) and control the dominant species of pests by Beauveria bassiana. The obtained results cleared that, the three tested plants infested with Aphis gossypii, Myzus persica, Liriomyza trifolii, Tetranychus telarius and Thrips tabaci. The population of T. tabaci recorded high individuals on the three tested plants during the two successive seasons. The two climatic factors proved to have no significant effect on the population density of T. tabaci nymph on the three tested plants during the two successive seasons. The effect of Beauveria bassiana, illustrated that percent reduction were increasing gradually by time from 3rd to 10 th day, whereas biofly liquid solution was more effect formulation than biover w. p. against T. tabaci nymph on the two tested plants A. ampeloprasum and A. graveolens during the two successive seasons. | ||
