Flower chafer beetle is a damaging pest of pulse flowers. However, its occurrence on maize cob has not been reported in maize. In this study, infestation of flower chafer beetle on maize cob was reported incidentally from Bundelkhand region of India. The invasion of flower chafer beetle was recorded in farmer field from three districts (Jhansi, Datia, and Tikamgarh) of Bundelkhand region. The level of infestation recorded was 5-7 beetles per five plants on maize cob at the time of peak grain formation time. Adult beetles were found to feed vigorously on the maize grain. Important taxonomic characters of the flower chafer beetle found on maize were also recorded in this study. Maximum infestation was found in Pipra-Jhansi at a cob formation stage in maize while the minimum infestation was observed in maize cob at Daryankala – Tikamgarh. The local check showed minimum infestation as compared to single cross hybrids (DHM-121, DHM-117). The maximum yield was obtained from a single cross hybrid (DHM-121, DHM-117) and minimum yield from a local check. Regular monitoring of flower chafer beetle on maize should be carried out in order to assess its damage potential and to develop appropriate management practices.
