The field surveys revealed the presence of several naturally-occurring natural enemies (predators and parasitoids) on <em>G. crouanii</em> in the major coconut growing regions in the Fiji Islands <em>viz.</em>, Viti Levu, Vanua Levu and Taveuni. Two species of egg parasitoids, <em>Paranastatus verticalis</em> Eady and <em>Paranastatus nigriscutellatus </em>Eady were recorded as the most prevalent natural enemies, of which <em>P. verticalis</em> was the dominant species.&nbsp; This paper presents information from field and laboratory studies on the pest and dominant natural enemy and role of <em>P. verticalis</em> on the population suppression of <em>G. crouanii</em> in Fiji. &nbsp;The release of <em>P. verticalis</em> and field sanitation were the two best management practices identified that contributed to the improvement of plant health toward the management of <em>G. crouanii</em>.</p> <p>&nbsp;</p> <p><strong><em>Keywords</em></strong> <strong>—</strong> <strong><em>Cocos nucifera </em></strong><strong>L., Coconut stick insect pest, </strong><strong><em>Graeffea crou</em></strong><strong><em>a</em></strong><strong><em>nii</em></strong><strong>,</strong> <strong>natural enemies, </strong><strong><em>Paranastatus verticalis</em></strong><strong>, Fiji</strong>.</p> <p>&nbsp;</p&gt;}, number={1&2}, journal={Asia Pacific Journal of Sustainable Agriculture, Food and Energy}, author={Deesh, Aradhana and Joshi, Ravindra and Jokhan, Anjeela and Khan, Mohammed and Jerard Bosco, Augustine}, year={2020}, month={Oct.}, pages={1-14} }
