Test 2. The same variables were generated according to procedure described in preceding test except that fruit fly larvae reared in Pa or Wd were both exposed to parasitoids in -Wds substrate only. Treatments were subsequently referred to as (Pa-Wds)2 and (Wd-Wds)2.
Test 3. Fruit fly larvae reared in Pa and Wd were both exposed to parasitoids in -Pus substrate only. As in Test 1, similar procedure was followed in the processing of samples and data collection. Treatments were sub- sequently referred to as (Pa-Pus)3 and (Wd-Pus)3.
Data analysis. Data on proportion of responding
D. longicaudata females, rate of parasitization, and
percentage parasitoid progeny yield were compared
between paired treatments by Student’s t-test at P
