Abstract:
تعد الافات الزراعية من المشاكل الخطيرة التي تواجه الانتاج الزراعي وللمناخ دور كبير في ظهورها وانتشارها خاصة عندما يشذ عن معدلاته او تفوق او تقل عن متطلبات المحصول. تهدف الدراسة الى تسليط الضوء على العلاقة بين الخصائص المناخية لمحافظة البصرة والافات الزرا | Agricultural pests are regarded serious problems that face agricultural production. Climate has a great role in their appearance especially when its rates go up or down the needs of the crop. The present study aims at shedding light on the relationship between climatic characteristics of Basrah province and the agricultural pests that infect the crops of (palms, wheat, tomato, eggplant, cucumber, watermelon, melon, okra and onion). These agricultural crops have a great economic and trophic importance. Therefore, production rates should be raised and its quality should be improved by observing agricultural pests whether they are diseases or insects that affect the quantity and quality of production. Especially if we know that new insects have entered Iraq like Tuta Absoluta and the Red Palm Weevil which started to affect many agricultural crops. Add t this the endemic diseases like Leaf Blights, Fusarium Wilt, and Powdery Mildew which greatly affect the production despite of the suitability of the climatic conditions and other natural conditions. The collection of the data of the study was done through field work. Four sites were chosen (Karmat Ali, Abo - Alkhaseeb, Aldair, and Az - Zubair) to observe the agricultural pests that infect the crops involved in the study starting from the beginning of the agricultural season 2015 - 2016 and to determine the rate of prevalence for each crop according to the location of prevalence. The study is composed of three chapters in addition to the introduction and conclusions. The first chapter is devoted to the analysis of the climatic characteristics of Basrah province, especially those factors that are related to the agricultural process like solar beams, temperature, relative humidity, winds and dust. Chapter two involved the climatic requirements of the crops under study. Chapter three is concerned with the field observance of the diseases that infected the crops and also the insects and natural plants (grass). The study concluded that the majority of the known diseases appear in different rates on the crops. There appeared also some affections caused by insects especially Tuta Absoluta and Red Palm Weevil. The study also concluded that the prevalence of the diseases and insects didn’t reach to the extent that classify them to be epidemic, their prevalence percentages were somehow reasonable within the season 2015 - 2016.
