Eight varieties of fennel viz., UF-205, UF-206, JF-376, HF-118, HF-125, GF-2 RF-101 and the local were tested for their preference by L. serricorne. The influence on developmental period, adult emergence, ovipositional response, incubation period, grain damage (%) and weight loss (g), growth index and the physico-chemical characters were studied. On the basis of different parameters, GF-2 and UF-206 were comparatively less susceptible; RF-101, HF-125 and local were moderately susceptible, whereas, JF-376, HF-118 and UF-205 were among the highly susceptible varieties.
