Abstract

The contribution and safety of the natural enemies is often neglected whenever a module is developed to manage major pest of the crop. So, field experiments were conducted to evaluate the different IPM modules for the management of brinjal shoot and fruit borer, Leucinodes orbonalis along with their safety towards predatory coccinellids during Rabi 2020-21 and Kharif 2021-22 at Zonal Agricultural and Horticultural Research Station (ZAHRS), Shivamogga. The results revealed that the Bio Intensive Pest Management (BIPM) module was ultimately the most promising and recorded higher number of coccinellids compared to IPM module, chemical intensive Farmers practice module and untreated control during both seasons recording mean number of 1.96 adult coccinellids/plant. This highlights the scope to augment the natural enemies and maintain their population under BIPM module through which the infestation of L. orbonalis could be much more reduced.

Keywords

Leucinodes orbonalis, coccinellids, BIPM, Modules

Conclusion

Our study highlighted the negative impacts of chemical intensive modules on the coccinellid beetles which keep the sucking pest’s population under check. Bio-intensive module, untreated control and also IPM plots maintain significantly higher activity of coccinellids compared to chemical intensive farmers practice module.
