Melia azedarach
Host plants are needed in the establishment of an orchard; the species selected for this purpose impart factors affecting growth, resistance to infestation, and the harvest. The study of "Melia azedarach" (white cedar) as a host to this species revealed that "S. acuminatum" acquired insecticidal compounds that increased its resistance to the quandong moth. Researchers then determined that neurotoxins found in the host plant, and other substances harmful to mammals, can pass into the harvested fruit.
