The study aimed to decipher the variation in constitutive plant biochemicals, and their influence on development, reproduction and survival of Lipaphis erysimi (Kaltenbach) (Aphididae: Hemiptera) on diverse Brassica juncea (L.) Czern & Coss. (Brassicales) cultivars. These studies revealed significant differences in total nymphal, reproductive and developmental periods, fecundity and offspring survival of L. erysimi on the test B. juncea cultivars. Toal developmental period was significantly longer, while fecundity and survival were lower on Pusa Mustard 27, NRCHB 101, RLC 3, RH 749, RH 725, DRMR 150-35, Pusa Mustard 26 and Pusa Mustard 25, except in a few cases. Further, total protein, antioxidants, tannins, phenols, FRAP, glucosinolates, photosynthetic pigments and different enzymes tested were significantly higher, and total sugars lower in Pusa Mustard 32, Pusa Mustard 30, NRCHB 101, RLC 3, DRMR 150-35, Pusa Mustard 26 and Pusa Mustard 27 as compared to other B. juncea cultivars, except in a few cases. Total sugars exhibited significant and positive association with survival of L. erysimi, while total protein, ferric ion reducing power, chlorophyll A, carotenoids, catalase, phenyl ammonia lyase and tyrosine ammonia lyase showed significant and negative correlation with survival of L. erysimi. Further, the biochemical constituents suggested 94.99, 95.88, 95.30, 97.06 and 84.75% variation in total nymphal, reproductive and total developmental periods, fecundity and survival of the L. erysimi on the test B. juncea cultivars, respectively. Overall, DRMR 150-35, RLC 3, NRCHB 101 and Pusa Mustard 26 have higher amounts of anti-nutritional defence compounds and antioxidative enzymes, distress the growth and survival of L. erysimi, and thus could be deployed in Brassica improvement programme.

该研究旨在破译不同芥菜 ( Brassica juncea (L.) Czern & Coss ) 上植物组成生化物质的变化及其对Lipaphis erysimi (Kaltenbach)（蚜科：半翅目）的发育、繁殖和生存的影响。（芸苔目）栽培品种。这些研究表明，在测试芥菜品种上，甜菜的总若虫、生殖和发育期、繁殖力和后代存活率存在显着差异。除少数情况外，Pusa Mustard 27、NRCHB 101、RLC 3、RH 749、RH 725、DRMR 150-35、Pusa Mustard 26 和 Pusa Mustard 25 的总发育期明显较长，而繁殖力和存活率较低。此外，Pusa Mustard 32、Pusa Mustard 30、NRCHB 101、RLC 3、DRMR 150-35、Pusa 中的总蛋白、抗氧化剂、单宁、酚类、FRAP、芥子油苷、光合色素和不同的测试酶显着较高，总糖较低。 Mustard 26 和 Pusa Mustard 27 与其他芥菜品种相比，少数情况除外。总糖与菌体存活率呈显着正相关，总蛋白、铁离子还原力、叶绿素A、类胡萝卜素、过氧化氢酶、苯基解氨酶、酪氨酸解氨酶与菌体存活率呈显着负相关。此外，生化成分表明，在测试芥菜品种上，甜菜的总若虫期、生殖期和总发育期、繁殖力和存活率分别存在 94.99、95.88、95.30、97.06 和 84.75% 的变异。总体而言，DRMR 150-35、RLC 3、NRCHB 101 和 Pusa Mustard 26 具有较高含量的抗营养防御化合物和抗氧化酶，会抑制erysimi的生长和存活，因此可用于芸苔属改良计划。
