Ushbu maqola poliz pashshasining (Myopardalis pardalina Big.) bioekologik xususiyatlarini poliz ekinlari agrotenziyasida o'rganishga bag'ishlangan. Zarafshon vodiysining iqlim sharoiti bu hasharotning rivojlanishi uchun qulay va poliz pashshasi polizchilik xo‘jaliklariga katta zarar yetkazadi. Shuning uchun biz qovun chivinining miqdoriy ko'rsatkichlarini ularning rivojlanishining turli bosqichlarida o'rganishni dolzarb deb hisoblaymiz.
