Elaeidobius kamerunicus is essentially the sole insect pollinator that efficiently pollinates oil palm, a major commodity crop accounting for 31.4% of the world’s oils and fats production. Despite its importance, in-depth molecular studies of this pollinator are severely lacking. The scarcity of molecular information to complement the current biological knowledge of E. kamerunicus warrants an investigation into the genome features of the pollinator. This aids in understanding the molecular mechanisms of plant-insect interaction during pollination events. Genome size estimation was conducted on Malaysian-bred males and females E. kamerunicus using flow cytometry and k-mer analysis on genome survey sequencing data. The cytometric analysis underestimated the genome size compared to the computational sequence-based method with differences of 157 megabase (Mb) to 179 Mb for the female and male E. kamerunicus, respectively. Genome sizes estimated from k-mer analysis were 365.93 Mb (female) and 380.73 Mb (male). Low sequence repeats ratios of 43.49% (female) and 43.70% (male) and high heterozygosity ratios of 1.92% (female) and 1.62% (male) were obtained. The average guanine-cytosine (GC) content of the female genome was 33.48%, and 31.71% for the male. These results lay the groundwork for E. kamerunicus genomic studies.
