MANAGEMENT OF APHID, LIPAPHIS ERYSIMI (KALTENBACH) (HOMOPTERA: APHIDIDAE) IN CANOLA (BRASSICA NAPUS L.) CROP USING NITROGENOUS FERTILIZERS AND SYNTHETIC INSECTICIDES

چکیده
Field experiment was conducted at the farm of Faculty Agriculture, GomalUniversity, Dera Ismail Khan to determine integrated effect nitrogenous fertilizer and syntheticinsecticides on aphid, Lipaphis erysimi (Kaltenbach) (Homoptera: Aphididae) population in canolacrop during 2010-11. Results showed that tested insecticides significantly reduced aphid populationcompared control. Minimum (8.67aphids) were recorded after 3rd week treatment with karate 2.5EC (625ml.ha-1) using medium dose (58kg.ha-1) nitrogen fertilizer. The same also provided maximum (1246.91kg.ha1) grains yield. It concluded from present studies testedlevels had no population, while synthetic significantlyreduced pest infestation.

متن کاملPlant spacing - a non polluting tool for aphid (Hemiptera: Aphididae) management in canola, Brassica napus
تحقیق حاضر برای به دست آوردن اطلاعاتی از تأثیر فاصله‌ی بین ردیفی گیاه Brassica napus L. روی جمعیت شته‌ها آغاز شد. سه فاصله‌ی خطی (20، 30 و 40 سانتی‌متری)، با فاصله‌ی ثابت نه سانتی‌متر بین هر گیاه، روی آلودگی شته و تأثیرش روی محصول دانه ارزیابی شد. اطلاعات جمع‌آوری و تصحیح شده روی پارامترهای ثابت نشان داد که افزایش فاصله‌ی خط‌ها با جمعیت شته رابطه‌ی معکوس دارد. با کاهش فاصله‌ی داخلی ردیف‌ها، اف...

For the enhancement of cultural control, the agricultural practices such as intercropping can profoundly affect the insect pest populations. Studies were undertaken to examine the effects of intercropping wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) with canola (Brassica napus L.) on the incidence of aphid (Hemiptera: Aphididae) population and related crop yield. Study observed ...
