الحشرات التي تصيب النباتات
هي انواع عديدة ولابد ان نعلم ان المحصول اذا ظهر بيه بعض الحشرات فانه معرض للانهيار بالكامل والخسارة الكاملة للفلاح وبعض قائمة الحشرات سنتعلم عليها الان هناك أنواع عديدة من العناكب كالأحمر والأصفر التي تتوافق ألوانها مع البيئة الجافة. ويستدل على الإصابة بالعنكبوت الأحمر - الذي يشاهد بصعوبة على النبات - وجود شبكة من الخيوط الدقيقة المتجمعة تمتد بين ورقة وأخرى ويشاهد العنكبوت ينتقل بينها.

The China Property Forum is an economics and finance forum dedicated to discussion of Chinese and global real estate markets, including China house prices, global house prices, housing affordability, and the likelihood of a global house price crash or China house price crash. Is there a Chinese housing bubble? Will house prices crash, boom or stagnate? Is it better to buy using a home loan, or rent and save the difference? How might a credit crunch or peak debt environment impact Chinese property prices? Is the Chinese property market a pyramid scheme or Ponzi scheme? Can house prices rise forever as people bet on future gains, refinance their mortgage and borrow against equity, or can we find a more sustainable long term approach to managing the Chinese housing market? These are the type of questions we hope to address here, at the China Property Forum, the premier real estate site for property bears, bulls, investors, and speculators! Whether you're a Property Investor, First Home Buyer (FHB) or you're a happily renting tenant, this forum has something for everyone.
