Ten different maize germplasm (inbreds) of 15 days old were studied for their oviposition preference tomaize stalk borer, Chilo partellus (Swinhoe) on the basis of different plant parameters viz., (i) Averageplant height, (ii) Average number of eggs per plant, (iii) Average number of egg masses per plant, (iv)Serial number of leaves received eggs (leaf from the bottom to top of the plant), (v) Average percentageof plant received eggs, (vi) Average percentage of leaves received eggs. Maximum egg laying wasobserved in HKI-1128 (15.02) and minimum in HKI-161(2.23). It was observed that third leaf (frombottom to top of the plant) was most preferred for oviposition by gravid females of C. partellus.Ovipositional preference was not found to be influenced by plant height. Similarly, average number ofeggs is more or less the same in each egg mass irrespective of the germplasm. The average percentage ofplants received eggs and average percentage of leaves received eggs by C. partellus showed significantdifferences between the resistant and susceptible maize germplasm. The mean egg mass was foundmaximum in HKI-1128 (1.03) and minimum in HKI-161(0.11), implying that the moths ensured greatersurvival of the freshly hatched larvae to continue the progeny on susceptible germplasm than to geteliminated on resistant ones.
