The spread of this pest is widely due to the fly's developed resistance to certain insecticides.
This has been a major issue combatted by attempts from the Florida Fruit and Vegetable Association (FFVA) to mitigate the infestation and spread of these pests.
However, due to previous spreading of L. trifolii through exported goods, L. trifolii are already a major pest of ornamentals in California.
The California chrysanthemum industry lost approximately $93 million to damage caused by L. trifolii in the 1980s.
Insecticides also kill off parasitoids that inhabit the area.
Thus, the use of insecticides not only damages the ecosystem, but also reduces the population of the main form of biological control for L. trifolii.
