Abstract

Halictophagus sp is a strepsipteron parasitoid of the mango leafhopper, Idioscopus clypealis (Leth). Its occurrence was observed and monitored among mango tress located inside the University campus from May 1999 to May 2000. Collection was done by sweep net on a weekly basis. Results showed that both parasitoid and its host insect were present on mango trees throughout the collection period. Annual mean parasitization reached 5.12%. No significant correlation was obtained between the rate of parasitization and the relative density of the host insects. Likewise, no significant correlation was found between rate of parasitization and the mango variety attacked by the leafhopper host. The surveys conducted from December 1999 to October 2002 showed that the parasitoid is also present in Luzon is Batac Ilocos Norte, Sto. Domingo Ilocos Sur, Ilagan Isabela, Masinloc Zambales, Munoz Nueva Ecija, Calatagan Batangas), Palawan is (Puerto Princesa), Negros is (Sibulan Negros Oriental, Manjuyod Negros Oriental), and Mindanao is (Manresa Cagayan de Oro City, Kidapawan North Cotabato, Opol Misamis Oriental). The parasitoid was collected from mango trees whether these were sprayed with insecticides or not.
