摘要: Lathyrus sativus L. (Fabaceae) is an important pulse crop of Asia, Europe, and Africa. Infestation by the aphid, Aphis craccivora Koch (Hemiptera: Aphididae) causes stunted growth plants reduces seed production. Females lay nymphs on leaves flowers sativus. Hence, it relevant to study importance leaf wax compounds (long-chain alkanes free fatty acids) from two cultivars [BIO L 212 Ratan (BIO) Nirmal B-1 (NIR)] as short-range attractant stimulant for nymph laying in aphid. The TLC, GC-MS GC-FID analyses n-hexane extracts revealed 18 n-alkanes n-C15 n-C36 14 acids C12:0 C22:0. Pentadecane was predominant among both cultivars. Palmitoleic acid pentadecanoic were waxes BIO NIR, respectively. attracted towards compared control solvent (n-hexane) Y-tube olfactometer bioassays. A synthetic blend either pentadecane, tridecanoic acid, linoleic at similar amounts present one equivalent BIO, or docosane, pentacosane, heptacosane, tritriacontane, NIR acted stimulated females nymphs. But, latter more attractive than former blend, hence, this could be employed development baited traps pest management strategies.
