大溪地巴戟天成熟果实对三种近缘种（D. melanogaster、黑腹果蝇D. simulans和D.毛里求斯）。绿色和腐烂的水果对所有供试物种均无毒性。短脂肪酸被发现存在于大量的成熟果实的提取物。最丰富的（辛酸）进行了测试，其毒性纯剂量依赖性的方式; D。sechellia比D.黑腹菌转化为辛酸。单用辛酸似乎就足以解释果肉的毒性作用。腐烂的果实中含量较少，而绿色果实中则没有。
The ripe fruit of Morinda citrifolia, host plant for Drosophila sechellia is highly toxic for three closely related species (D. melanogaster, D. simulans, and D. mauritiana). Green and rotten fruits are not toxic for all species tested. Short fatty acids were found to be present in large quantities in the extract of the ripe fruit. The most abundant (octanoic acid) was tested pure for its toxicity in a dose-dependent manner; D. sechellia is five to six times more resistant than D. melanogaster to octanoic acid. Octanoic acid alone seems to be sufficient to explain the toxic effect of the pulp. It is less abundant in the rotten fruit and absent in the green fruit.
