Relative susceptibility of some promising fennel varieties against Lasioderma serricorne (Fab.).

Abstract

The present investigation was conducted to examine the varietal preference of fennel against
Lasioderma serricorne (Fab.) under laboratory conditions in the Department of Entomology, College
of Agriculture, Bikaner from March, 2014 to Aug., 2014. Ten varieties of fennel viz., GF-2, UF-206,
RF-143, RF-145, HF-125, RF-178, RF-101, HF-118, RF-205 and Local were tested against L. serricorne
in relation to ovipositional response, developmental period, adult emergence, per cent grain damage
and weight loss. On the basis of different parameters, GF-2 and UF-206 were found comparatively
less susceptible while RF-101, HF-125, local, RF-205 and RF-143 were moderately susceptible,
whereas, HF-118, RF-178 and RF-145 were the most susceptible varieties.
