Population dynamics of major insect pests infesting fennel (Foeniculum vulgare L.)

Abstract

Fennel (Foeniculum vulgare L.) is major seed spice crop grown in India. Insect- pests are one of the major limiting factors for higher production of fennel. The fennel crop was grown for two consecutive years during rabi, 2017-18 and 2018-19. During the course of study, five different insect pests viz., thrips, Scirtthrips dorasalis Hood; cow bug, Oxyrachis spp., gram pod borer, Helicoverpa armigera (Hunbner) Hardwick; aphid, Hyadaphis coriandri Das and seed midge, Systole albipenis Walker were recorded on fennel at various stages of the crop.
