摘要

Chlorpyrifos is one of the most used insecticides in agro-ecosystems and is repeatedly applied due to the increase in pest resistance, which leads to environmental accumulation. The aim of this work was to evaluate the effect of chlorpyrifos on growth and aflatoxin B-1(AFB(1)) production by fourAspergillussectionFlavistrains, under different water conditions-a(W)(0.93, 0.95 and 0.98)-on maize-based medium (MMEA) and maize grains supplied with 0.06 to 1.4 mmol/L of chlorpyrifos. MMEA plates were incubated at 18, 28, and 37 degrees C and plates with maize grains at 25 degrees C during 21 days. Chlorpyrifos stimulated the growth and AFB(1)production of non-target organisms, such asAspergillussectionFlavistrains, both at low (0.06 mmol/L) and at high concentrations (1.4 mmol/L) on MMEA and maize grains. Stimulation occurred over a wide range of temperature and a(w)conditions. The toxin concentration produced by the two strains on MMEA at 18 degrees C increased when the concentration of chlorpyrifos also increased, being most significant at 0.6 mmol/L. In conclusion, the presence of chlorpyrifos should be considered as a factor, together with environmental conditions, for the development of effective production practices of maize grains, in order to avoid fungal growth and AFB(1)production, to prevent both economic losses and risks to human and animal health.
