28. The parasitoid wasp, Leptopilina heterotoma, injects eggs into young larvae of fruit flies, Dro- sophila melanogaster. One reaction by the flies is to self-medicate by consuming alcohol (etha- nol), which is naturally present in the decaying fruits where they live. The ethanol reduces ovi- position by wasps, and it increases death rates of wasp larvae within parasitized flies. Kacsoh et al. (2013) investigated whether the presence of the wasp influences where female fruit flies prefer to lay their eggs. They presented female flies in cages with two dishes of fly food, one having 6% ethanol and the other with 0% etha- nol. They recorded the proportion of eggs laid in the 6% ethanol dish when females were placed with female wasps, with male wasps, or with no wasps. The data below give the proportion of eggs laid in the ethanol dish for multiple repli- cates of each wasp treatment. No wasp: 0.25, 0.40, 0.46, 0.44 Male wasp: 0.42, 0.47,0.31, 0.52 Female wasp: 0.89, 0.83, 0.92, 0.93
