Abstract

Transcriptomics or the global profiling of transcripts or expressed genes in an organism through next generation sequencing may offer support to the effort of investigating field parasitism. Through transcriptome analysis, transcripts from both the host and the natural enemy can easily be detected. Additionally, transcript sequences of other species of potential parasitoids may appear from the transcriptome sequencing data. This study aims to investigate the presence of natural enemy transcripts in a field population of the coconut scale insect (CSI), Aspidiotus rigidus Reyne (outbreak species) and A. destructor (the non-outbreak species) through transcriptome sequencing. Results show that transcripts from field samples of CSI have similarity to some known parasitoids indicating parasitism in the field. Transcriptomics of Comperiella sp., a new species of a parasitic wasp discovered in a survey for natural enemies of the cocolisap in Calauan, Laguna in 2017, also revealed similarities to the same species in parasitoids.
