Abstract AR
أجريت الدراسة في منطقة ريجوا حديثة الاستصلاح على طريق مصر الإسكندرية الصحراوي خلال الموسم الشتوي الذي بدأ 9 أكتوبر 2001 و الموسم الصيفي الذي بدأ 21 إبريل 2002.
و تشير النتائج المتحصل عليها إن الموسم الشتوي كان أكثر حساسية بالإصابة بأنواع المن المختلفة عن الموسم الصيفي.
و من ناحية أخرى وجد أن من القطن Aphis gossypii (Glover) هو أكثر الأنواع انتشارا على نباتات الكوسة خلال موسمي الزراعة.
وقد استخدمت سبع معاملات آمنة لمكافحة المن و ذلك للمحافظة على البيئة، و قد وجد أن (Transparent Biofly, Transparent Biovar) كانت أكفأ المعاملات حيث سببت أكثر خفض في نسبة الإصابة بالمن و أعلى زيادة في محصول الكوسة في الفدان خلال موسمي الزراعة، و ينصح باستخدام إحدى المعاملتين المذكورتين في حقول الكوسة لمكافحة المن بكفاءة عالية.
Abstract EN
Field studies were carried out on squash plants cultivated in sandy soil in newly reclaimed land at Regwa farm (62 km.
north Cairo) during the winter and the summer plantations (October, 2001 and April, 2002, respectively).
Results indicated that squash plants in winter plantation were more susceptible to aphids' infestation than those sown in summer.
Aphis gossypii was found to be the most dominant and abundant aphid species on squash plants, being 56.38 and 62.10 % for dominance degrees and 31.25 and 17.60 % for abundance degrees in winter and summer plantations, respectively.
The safe materials Kz oil, Pirimor, Biovar and Biofly were evaluated against aphids in squash fields using two techniques.
In the first technique, the populations of alate aphids were counted by green water pan during the period from plant emergence till fruit ripening.
However, in the second technique, direct counts of aphids on the squash leaves were made during the growing period of the plants.
The maximum reduction in aphid population and the highest squash yield were obtained after using transparent Biovar or transparent Biofly.
Therefore, it is advisable to use transparent Biovar or transparent Biofly for controlling aphids in squash fields.
Significant negative correlation was found between the accumulated mean number of aphids and the yield of squash fruits.
