Table 1. Mean percent larval parasitization of B. dorsalis and parasitoid
progeny yield compared between fruit fly larvae that developed in papaya
or wheat diet then exposed concurrently to D. longicaudata in a pair of
stinging units. Treatment means were compared in each test by Student’s

a Abbreviations Pa and Wd refer to papaya fruit or wheat diet, respectively,
the culture media in which fruit fly larvae developed. The suffixes
-Pus and -Wds refer to papaya puree or wheat diet, respectively, the
substrates in which treatment larvae were mixed with and exposed to
parasitoids in stinging units. Numerical subscripts indicate test num
