Ants can act as beneficial insects and some are harmful. At PT Great Giant Pineapple (GGP), it was known that the PLM virus was carried by mealybugs from Dysmicoccus brevipes and D. neobrevipes species. “Mealybugs can’t move from one location to another with a long enough distance. The dispersal of mealybugs is assisted by ants,” said Dr Tri Asmira Damayanti, MAgr, IPB University Lecturer in Ant Identification training at the Plant Protection Laboratory, PT Great Giant Pineapple (GGP), some time ago.
