Rayap yang menyerang tanaman kakao menyebabkan produktivitas kakao menurun secara signifikan. Penelitian telah dilakukan di kebun kakao di Kecamatan Manyak Payed, Kabupaten Aceh Tamiang pada Juli 2021-Januari 2022. Tujuan penelitian ini adalah untuk menginventarisasi jenis rayap yang menyerang tanaman kakao. Pengkoleksian rayap menggunakan Metode Koleksi Koloni yaitu dengan mengkoleksi beberapa individu dari kasta prajurit dan pekerja dalam satu koloni. Hasil penelitian menunjukkan sebanyak 9 jenis rayap yang menyerang tanaman kakao. Rayap berasal dari 4 sub famili yaitu Macrotermitinae, Nasutitermitinae, Coptotermitinae dan Termitinae. Jumlah koloni yang dikoleksi pada luas kebun kakao polikultur keseluruhan 1,24 ha sebanyak 78 koloni. Macrotermitinae sebanyak 7 koloni (9%), Nasutitermitinae 10 koloni (13%), Coptotermitinae 4 koloni (5%) dan Termitinae 57 koloni (73%). Persentase serangan rayap terhadap kebun kakao dengan luas 1,24 ha mencapai 24%. Faktor penyerangan rayap terhadap tanaman kakao disebabkan oleh tumpukan kayu, penggunaan kayu mati sebagai penyangga serta tumpukan serasah di sekitar tanaman kakao.
