Abstract

The experiment was conducted at Horticulture farm S.K.N. College of Agriculture, Jobner (Rajasthan) during Kharif, 2017 to identify the infestation of major insect pests of okra (leaf hopper, whitefly and shoot and fruit borer). Ten okra varieties were screened to know their response on the basis of morphometric and biochemical characters. Based on the infestation of major insect pests of okra the grading is done as least, moderately and highly susceptible. The morphological characters of plant showed that the variety IIVR-11 which had more hairiness (trichome density), was found least susceptible for the leaf hopper, whitefly and shoot infestation. Whereas, the variety Parbhani Kranti was found to be most susceptible which had less hairiness to the variety IIVR-11. The total phenols had significant negative effect with leaf hopper and whitefly and non-significant effect with shoot and fruit borer and free amino acid had significant positive effect with leaf hopper, whitefly and shoot

Conclusion

The morphological characters of plant showed that the variety IIVR-11 which had more hairiness (20 per sq. mm trichome density), was found least susceptible for the leaf hopper, whitefly and shoot infestation. Whereas, the variety Parbhani Kranti was found to be most susceptible which had less hairiness (13 per sq. mm trichome density). The biochemical parameters showed that the variety IIVR-11 which had higher amount of total phenols (4.89%) and lower amount of free amino acids (2.83%) was found least susceptible for the major insect pests infestation. Whereas, the variety Parbhani Kranti was found to be most susceptible which contained these parameters contrary to the variety IIVR-11.
