Performance of Trichogramma japonicum under field conditions as a function of the factitious host species used for mass rearing.
Different factitious hosts were used to mass rear Trichogramma japonicum Ashmead in different parts of the globe because thorough details were lacking in both the laboratory and the field. The objective of this study was to compare, parasitoid, T. japonicum reared in different factitious hosts. Thre...

The highest parasitism by T. japonicum was observed on E. kuehniella eggs.
