Responses of Liriomyza huidobrensis and L. trifolii to pesticides
In the United Kingdom, experiments were carried out in order to determine the applicability of different pesticides in eradication campaigns against Liriomyza huidobrensis (EPPO A1 pest) and L. trifolii (EPPO A2 pest).
Compared to a susceptible laboratory population field populations of L. trifolii showed resistance to the pyrethroids tested as well as some evidence of resistance to gamma-HCH. No evidence of resistance to organophosphates was observed in L. trifolii.
L. huidobrensis also showed resistance to the pyrethroids tested, but its response to gamma-HCH was similar to that of susceptible L. trifolii. Furthermore, L. huidobrensis showed an eight times higher tolerance to organophosphates than the susceptible L. trifolii population.
