Resistance of some varieties/clone of lucerne to spotted alfalfa aphid, Therioaphis trifolii (Monell)



Resistance of some varieties/clone of lucerne to spotted alfalfa aphid, Therioaphis trifolii (Monell)



Indian Journal of Entomology 42(3): 403-407



The resistance mechanisms of the LLI, T9 and T9-85 varieties or clones of lucerne (see preceding abstract) to Therioaphis trifolii (Monell) were studied under field-cage conditions. The antibiosis mechanism of resistance was studied by comparing the mortality of nymphs on the different varieties; the cumulative mortalities of nymphs up to the age of 12 days were 15.0% on LLI, 83.0% on T9 and 86.0% on T9-85.
