Abstract
The objective of this study was conducted to evaluate the efficacy of four compounds ; achook 0.15% (Azadirachtin) ; cloves-oil (Syzyguim aromaticu) ;Plant extracts damaseia (Ambrosia maritime) and selecron 72.0% EC. (Profenofos) for controlling some squash plants pests; whitefly, Bemisia tabaci (Genn.); Aphis gossypii (Glover.), as well as its effects on squash leaves chlorophyll contents.
Obtained results cleared that cloves oil exhibited the highest reduction percentages of A. gossypii (97.0and 796.9) followed by damaseia extract (94.2&95.1), achook o.15 % (93.0&92.3), while, selecron was the lowest one (89.7and 788.2) after five days of treatment during 2011 and 2012 seasons. While, whitefly reduction percentages after five days of treatment showed that damaseia extract exhibited the highest reduction (100and100) and(98.2and100) of both adult and immature stages ,followed by selecron 72.0% (100& 89.7) and (97.5 &85.0), cloves oil (97.5 &91.2) ,(96.3 &89.4) and achook 0.15% (95.2 &83.2), (90.9 &82.3) during the two seasons respectively.
Squash leaves chlorophyll (a, b ) was the highest with cloves oil treatment, followed by damaseia extract,while it was lowest with both achook and selecron treatments.
