A review of the status of the larval parasitoid, Asecodes hispinarum Boucek, and of the pupal parasitoid, Tetrastichus brontispae Ferriere (Hymenoptera: Eulophidae), as biological control agents of the coconut leaf beetle, Brontispa longissima (Gestro) (Coleoptera: Chrysomelidae: Cassidinae), in the Asia-Pacific Region

The Coconut Leaf Beetle, Brontispa longissima, endemic to Indonesia and Papua New Guinea, has spread to many countries in Asia and the Pacific region, where it has become a serious pest.Several countries have achieved significant control of B. longissima by releasing and establishing parasitoids, such as Asecodes hispinarum and Tetrastichus brontispae, which attack immature stages of the pest.A review of previous works undertaken on the biological control of the Coconut Leaf Beetle in these countries and elsewhere indicate that a combined release of A. hispinarum, with T. brontispae is an excellent tool to control B. longissima.Biological control of B. longissima is also seen to be environmentally sound and cost effective.
