ABSTRACT

The cocoa pod borer, Conopomorpha cramerella (Snellen) is a serious pest in cocoa plantations in Southeast Asia. It causes significant losses in the crop. Unfortunately, genetic resources for this insect are extremely scarce. To improve these resources, we sequenced the transcriptome of C. cramerella representing the three stages of development, larva, pupa and adult moth using Illumina NovaSeq6000. We have identified a number of genes that are involved in reproduction and development such as genes involved in general function processes in the insect. Genes found to be involved in reproduction such as porin, dsx, bol and fruitless were associated with sex determination, spermatogenesis and pheromone binding. This serves as a valuable genetic repository of the insect for potential RNA interference and genome editing.
