Kerusakan yang ditimbulkan oleh larva PBK berupa rusak dan mengeriputnya biji, timbulnya warna gelap pada kulit biji yang mengakibatkan turunnya berat dan mutu produk. Untuk mengendalikan hama penggerak buah kakao C. cramerella tersebut umumnya petani menggunakan insektisida kimia. Penggunaan insektisida secara terus-menerus dikhawatirkan menimbulkan masalah yang lebih berat, antara lain terjadinya resistensi hama, pencemaran lingkungan, dan ditolaknya produk akibat residu pestisida yang melebihi ambang toleransi.Pengendalian hayati dengan menggunakan entomopatogen merupakan salah satu dari konsep PHT.
