Biochemical mechanism of resistance in some Brassica genotypes against Lipaphis erysimi (Kaltenbach) (Homoptera: Aphididae)
*Corresponding author E-mail : [email protected] INTRODUCTION The genus Brassica comprises an important group of cultivated vegetable and oilseed crops and have great economic importance worldwide. The cultivated species of Brassica include cabbage, cauliflower, kale, broccoli, Brussels sprouts, turnip, swede, oilseed rape, various mustards and other leafy vegetables (Hong et al. 2008). As oils...
متن کاملresistance characterization of different oilseed cultivars of brassica to mustard aphid, lipaphis erysimi (hem.: aphididae) under greenhouse conditions
the mustard aphid, lipaphis erysimi kalt, is one of the most severe pests of brassica species in iran and other tropical regions in the world. seven cultivars of three brassica species including b. napus (cv. licord, elite, okapi, hyola 401, and rgs003), b. juncea (cv. land race) and b. rapa (cv. park land) were evaluated to study the antixenosis and antibiosis resistance to l. erysimi under gr...
متن کاملInfluence of PGRs on carbohydrate content in Lipaphis erysimi (Kalt.).
Six compounds (IBA, chlorogenic acid, cytokinine, GA3, alar B-9 and maleic hydrazide) belonging to four different categories of plant growth hormones were used to study their effect on carbohydrate content in L. erysimi. The second instar nymphs (48 hr old) were given both dipping and leaf surface treatment with 1024 ppm concentration of compounds for two time intervals i.e. 48 and 96 hr. The c...
متن کاملPopulation Trend of Canola Aphid, Lipaphis Erysimi (Kalt.) (Homoptera: Aphididae) and its Associated Natural Enemies in Different Brassica Lines along with the Effect of Gamma Radiation on Their Population
Studies regarding the determination of population trend of Lipaphis erysimi (kalt.) and its associated natural enemies in different Brassica lines along with the effect of gamma radiation on their population were conducted at Agricultural Research Farm, Malakandher, Khyber Pakhtunkhwa Agricultural University Peshawar during spring 2006. Three different Brassica lines F6B3, F6B6 and F6B7 were us...
متن کاملاثر کوددهی نیتروژن و گوگرد در کلزا بر توانائی های زیستی شته خردل lipaphis erysimi (kaltenbach,1843) (hom.: aphididae)
شته¬ خردل kalt.)) lipaphis erysimi یکی از آفات مهم گیاه کلزا brassica napus l. است. تغییر کیفیت گیاه میزبان در نتیجه کوددهی می¬تواند بر توانایی¬های زیستی و انبوهی جمعیت حشرات گیاه-خوار تأثیر گذار باشد. این تحقیق به منظور بررسی اثر برهم¬کنش سطوح مختلف کوددهی نیتروژن (صفر، 150 و 225 کیلوگرم نیتروژن در هکتار) و گوگرد (صفر و 40 کیلوگرم گوگرد در هکتار) بر شاخص¬های رشدی و فیزیولوژیک کلزا و ویژگی های ...
