SUMMARY

The polyphagous stem borer Zeuzera multistrigata Moore, 1881 (Lepidoptera: Cossidae) is reported attacking Coffea arabica L., Glyptostrobus pensilis K.Koch and Passiflora edulis Sims in Vietnam. Field surveys in Dak Lak province in 2024 showed that Z. multistrigata outbreaks in G. pensilis stands resulted in damage incidence ranging from 44.1 to 94.1% and damage indices from 1.32 to 2.18. Damage was less severe in C. arabica and P. edulis, where the damage incidence ranged from 13.8 to 14.5% and the damage index from 0.40 to 0.42 in oneyear-old plants. Further studies are recommended to develop an integrated pest management plan for this pest on these new hosts.

Key words: Cossidae, Coffea arabica, Glyptostrobus pensilis, Passiflora edulis, Stem borer, Zeuzera multistrigata.
