This study was aimed at identifying host plant resistance sources of Solanum species against the dreaded brinjal pest, ash weevil. Myllocerus subfasciatus Guerin-Mene­ville. A total of 84 brinjal genotypes (both cultivated and wild) were screened for feeding preference/non-pre­ference against the ash weevil under field as well as in vitro conditions. All the cultivated and five wild genotypes (bitter brinjal, Solanum gilo Raddi; black nightshade, Solanum indicum L.; African eggplant, Solanum macrocarpon L.; Ethiopian eggplant, Solanum aethiopicum L. and Dutch eggplant, Solanum acculeatissimum Jacq.) were found highly susceptible to the ash weevil. The other wild species, namely tropical soda apple, Solanum viarum Dunal; nipple fruit (= cow’s udder) Solanum mammosum L.; European nightshade, Solanum nigrum L.; cockroach berry, Solanum capsicoides Allioni; Brazilian nightshade, Solanum seaforthianum Andrews; Turkey berry, Solanum torvum Sw. and sticky nightshade, Solanum sisymbriifolium Lam exhibited complete resistance to the ash weevil with leaf feeding damage ranging from zero to <1.00 (when scored on 0.00–10.00 scale). This study helped identify feeding antixenosis (feeding non-preference) as the major component of resistance in these wild genotypes against M. subfasciatus. Response of the ash weevil to these wild/cultivated genotypes and their volatiles has also been discussed in detail
