The endobiont braconid parasitoid, Aulacocentrum philippinense (Ashmead), was reared on three new hosts, namely, Crocidolomia binotalis Zeller in Mamana Uno, Sariaya, Quezon Province from July to November 1996 and on Maruca vitrata F. and Hymenia recurvalis (F.) in Cale, Tanauan, Batangas from 1979 to 1981. Parasitization level ranged from 0.16 to 90.8% (mean[plus or minus]se =24.3[plus or minus]33.9) out of the 2,612 field-collected third instar to fifth instar larvae reared in the laboratory. In C. binotalis, parasitization reached 72.3% based on 755 larvae collected from July to November 1996 but less than one percent in Maruca and Hymenia larvae. The record of A. philippinense on Maruca and Hymenia indicates possible adaptation of the parasitoid in the absence of preferred host.
