Initial observation on field infestation in Basilan and Zamboanga [Philippines] revealed mixed populations of various scale insect species on coconuts, with coconut scale insects (Aspidotus spp.) predominating in outbreak proportions in Basilan [Philippines]. Samples were taken to compare the abundance of scale insect species in Basilan, Zamboanga City and Zamboanga Sibugay, as well as obtain insights on the relative proportions and extent of mixing of scale insect populations per leaflet/tree and initially assess the qualitative responses of host plants.Questions are discussed in connection with the present pattern of occurrence of the CSI in those areas,where there is an outbreak in Basilan but not in Zamboanga, despite their relatively short geographic distance.
