Abstract

Marietta javensis was found to be a solitary ectoparasite. Eggs were laid on the pupa of the primary host or attached to the inner surface of the integument of the scale insect. The threshold temperature for development was 13,8 �C and the thermal constant 218,8 day-degrees. The female percentage of hyperparasites emerging from large hosts was more than double that from small ones. The life span of females was not reduced at 0% as compared with 50% RH, but that of males was only one-quarter as long as at 50% RH. Females lived longer than males on honey but not so long as males on water, pollen or without any food.
