Rorippa indica, a wild crucifer, has been previously reported as the first identified plant in the germplasm of Brassicaceae known to be tolerant towards the mustard aphid Lipaphis erysimi Kaltenbach. We herein report the full-length cloning, expression, purification and characterization of a novel R. indica defensin (RiD) and its efficacy against L. erysimi. Structural analysis through homolog...
A Novel Insecticidal Peptide SLP1 Produced by Streptomyces laindensis H008 against Lipaphis erysimi.
Aphids are major insect pests for crops, causing damage by direct feeding and transmission of plant diseases. This paper was completed to discover and characterize a novel insecticidal metabolite against aphids from soil actinobacteria. An insecticidal activity assay was used to screen 180 bacterial strains from soil samples against mustard aphid, Lipaphis erysimi. The bacterial strain H008 sho...
گیاه کلزا کشت عمده در استان خوزستان بوده و درصد بالای روغن دانهی آن سبب شده که سطح زیر کشت این محصول سال به سال افزایش یابد. یکی از آفات مهم کلزا در خوزستان شتهی خردل (Lipaphis erysimi Kalt.) است، ولی اطلاعاتی در خصوص سطح زیان اقتصادی (EIL) آن که در تصمیمگیری نحوهی کنترل این آفت ضروری میباشد، موجود نیست. از این رو آزمایشی در قالب طرح بلوکهای کامل تصادفی با 11 تیمار تراکم شته در 5 تکرار...
different species of aphids in rapeseed fields of khuzestan province were identified and the dominant ones were determined during 2002-2004 field sampling. base upon the collected data, population fluctuations of rapeseed aphids vs. their natural enemies were assessed. also biology of the aphids, major species was studied under controlled conditions. the results showed that lipaphis erysimi (ka...
