| Abstract | ||||
| The present work was conducted during two successive seasons 2011 / 2012 and 2012/2013 in order to study the population dynamics of aphids, leafhoppers and whitefly insect species infesting Solanaceae plants Eggplant, (Solanum melongena L.), Pepper (Capsicun annuun L.) and Tomato (Lycopersicum esculentum ), in Kasasine district, Ismailia Governorate, Egypt. Aphid species Aphis gossypii (Glov.), leafhopper insect species included Empoasca decipiens (Paoli), Empoasca decedens (Paoli), whitefly insect species was Bemesia tabaci (Genn.) and mites Tetranychus sp. The seasonal population abundance of A. gossypii on Eggplant, Pepper and Tomato plants showed two peaks. The first one occurred at 2nd of Oct., 4th of Oct. and 4th of Sept. on Eggplant, pepper and tomato plants, respectively. The second peak was recorded at 3rd of Dec. on Eggplant and Pepper, while Tomato plants at 4th of Dec. Two peaks occurred for both E. decipiens and E. decedens during the two seasons on Eggplant the first peak on1st of Nov. and the second peak2rd of Dec for the two season s respectively. On Pepper the first peak 4th of Oct. , and the second peak 2rd of Dec for E. decipiens and and1th of Dec while the first peak occurred on tomato plan2nd of Oct ts . Whitefly, B. tabaci on eggplant and Tomato plants in nymph at 4th Sept. in the first peak on Eggplant and Tomato plants , 4th of Nov. on Eggplant plants and 1st of Dec. in Tomato plants for the two seasons, respectively. While, adult stage the first one 2nd of Oct. for the two season , while the second season 2nd of Dec. on eggplant and 4th of Dec. on Tomato plants on both seasons. Mite Tetranychus sp., on Eggplant and tomato plants was recorded two peaks. The first on 2nd of Oct., 1st of Oct.and 1st of Oct., 4th of Sept. respectively. The second peak 3rd of Dec. on both seasons. The obtained results attributed in forecasting of the infestation of these pests on Solanaceae plants. Conclusively, from these results it could be concluded that through knowledge of the number of pests′ generations under study that can be used in a program to forecasting pests injuries and using it in an integrated pest management program. | ||||
