Abstract
This work was carried out in 1966 and 1967 to obtain a fundamental knowledge on the mass production of Allotrope sp. in the laboratory. Allotrope sp. is an effective larval parasite of Planococcus kraunhiae KUWANA, the pest insect of persimmon and citrus trees.
This parasite is preovigenic and the average number of ovarian egg is 482. The virgin female produces only male progeny.
The number of mummies produced by a female were 82 in average, 187 in maximum, and 25 in minimum, respectively. Of the total number of mummies, 85 per cent were produced on the day of emergence.
Of 2000 adults emerged newly from the mummies, 53 per cent was female, and male emerged earlier than female. Emergence rate is about 90 per cent.
