oviposition by Helicoverpa armigera (Lepidoptera:Noctuidae)","pub","s1.3","","","public",,,"Groundnut, induced resistance, oviposition, phytohormones, trichomes",,,"Jasmonic acid (JA) and salicylic acid (SA) are important phytohormones involved in plant resistance
against insect herbivory and pathogen infection. Application of JA and SA induces several defensive traits in plants.
Here we investigated the effect of JA and SA on trichome density in five groundnut genotypes [ICGV 86699, ICGV
86031, ICG 2271, ICG 1697 (resistant) and JL 24 (susceptible)]. The effect of JA- and SA-induced resistance on the oviposition
behaviour of Helicoverpa armigera on different groundnut genotypes was also studied. Pre-treatment with JA
increased numbers of trichomes in the insect-resistant genotypes, ICGV 86699, ICGV 86031, ICG 2271, and ICG 1697.
The induction was greater at 10 days after treatment. Jasmonic acid- and SA-treated plants showed a substantial
effect on the oviposition behaviour of H. armigera. Jasmonic acid application and herbivory reduced the number of
eggs laid by H. armigera in all the groundnut genotypes tested. However, a greater reduction was recorded on plants
pre-treated with JA. More egg layingwas recorded in JL 24 in all the treatments as compared to the insect-resistant genotypes.
These results suggested that pre-treatment with JA increased trichomedensity in groundnut plants, which conferred
antixenosis for oviposition by H. armigera.","2013","published",,"AoB Plants",,,"Oxford University Press",,"1-6",,,,,,,,,,,"TRUE",,"2041-2851",,,,,,"","http://dx.doi.org/10.1093/aobpla/plt053","http://scholar.google.co.in/scholar?as_q=%22Induced+resistance+in+groundnut+by+jasmonic+acid+and+salicylic+acid+through+alteration+of+trichome+density+and+oviposition+by+Helicoverpa+armigera+%28Lepidoptera%3ANoctuidae%29%22&as_epq=&as_oq=&as_eq=&as_occt=t","pub",,"","",,,,,,"",,,,,,,"",,,,,"",,,,,"","",,,,,"","",,,,,
