Abstract
The parasitoids and predators associated with armored scale insects on coconut were identified using 28S nucleotide regions. Based on BLAST hits, the parasitoids identified were Comperiella bifasciata, Pteroptrix sp., Coccophaginae sp., Encarsia heratyi, and Marietta sp., while the predators were Telsimia sp., Pseudoscymnus sp., Nothocolus sp., and Chilocorus cacti. However, low percent homologies were observed, ranging from 83-92%. All of the sequences of parasitoids and predators showed cytosine (C) and guanine (G) biases. Sequences of Co. bifasciata, Coccophaginae sp., E. heratyi, and Telsimia sp. were aligned among their samples, these shown with gaps, singleton variable sites and parsimony informative sites. In terms of nucleotide and haplotype diversities among the parasitoids, highest was obtained from Coccophaginae sp. and Pteroptrix sp., respectively. In the case of predators, only Telsimia sp. showed polymorphic sequence. Phylogenetic trees for parasitoids and predators were constructed.
