Abstract

An unidentified parasitoid attacking coconut scale insect (CSI), Aspidiotus sp., was discovered after series of intensive field surveys and collections in Davao region. The said wasp was suspected to be under the genus Aphytis and observed to be a potential biological control agent against the pest. Initial study results on its biology and behavior under laboratory conditions and its efficiency in the field were verified at PCA -Davao Research Center. Successful mass production of the parasitoid was developed in the laboratory. The technique involves rearing of coconut scale insect on squash fruit as host of the parasitoid. This method is currently being used to produce considerable number of parasitoids for field release in scale insect-infested areas. A satellite laboratory for the mass propagation of the parasitoid was established in Isabela City, Basilan for the control of coconut scale insect (CSI) infestation in the island. A large mass production laboratory is being proposed in Batangas and Laguna where heavy CSI infestations were found.
