Screening of rose varieties against Japanese beetle



 

ABSTRACT: The study was conducted in the farm of Sher-e-Bangla Agricultural University, Dhaka during April to December 2011 for screening rose varieties against Japanese beetle incidence. The study included twelve varieties of roses viz. Wild rose, Crazy love bi-color, Yellow star, Missing love, Compassion, Charming lady, Dream bangle, Sleepy moon, Sweet doll, Moon light, Sweet love and Mini Moni. Incidence of Japanese beetle showed significant variation due to the effect of varieties. Among the varieties, Sweet Love showed the lowest abundance of Japanese Beetle (1.5/plant), the lowest number (0.2/plant) of infested leaves, infested branch (1.3/plant) and infested flower (1.1/plant) per plant.
