The Leucaena psyllid HeteropsyHa cubana Crawford (Homoptera: Psyl/idae) has ~aused damaging ef fects to Leucaena leucocephala (Lam.) de Wit in Tanzania since its outbreak in 1992. Cultural, genetic and chemical controls havebel!n tried in some localised areas. In 1995, a hymenopterous parasitoids, Tamarixia leucaenae Boucek (Eupelmidae) was imported from Trinidad and Tobago for biological con-trol of this pest in Tanga and Morogoro areas. Mummies of the parasitoid were recordedfrom the sixth week after release. The population declined to the lowest level between November 1995 and January 1996 before building-up again to about 10 and 11 mummies per shoot in July for Tanga and Morogogro respectively. Spread of the parasitoidwas fairly fast, a...
