Abstract:
[Objectives]  To study the effects of chlorantraniliproleon on rice planthoppers and their parasitic natural enemies in paddy fields, together with changes in arthropod community parameters, in order to provide a scientific basis for the rational use of chlorantraniliprole. [Methods]  Four rice fields were treated with chlorantraniliprole and four control rice fields were selected in Suizhou city and Xiaogan city, Hubei province. Arthropods were collected using the suction method and their dominance, population density, and the correlation between rice planthopper abundance and that of their parasitic natural enemies, was compared between treated and control rice fields. [Results]  In most cases, there was no significant difference in the dominance and population density of rice planthoppers and that of their parasitic natural enemies between treated and control fields in 2011 and 2012. There was, however, a significant positive correlation between the number of rice planthoppers and that of their parasitic natural enemies in control and treatment fields in Xiaogan (2011: control field, R2=0.249, P=0.007; treated field, R2=0.462,P<0.001;2012: control field, R2=0.189, P=0.021; treated field, R2=0.212, P<0.014). However, no significant correlation between rice planthopper abundance and that of their parasitic natural enemies was found in the two treatment fields in Suizhou over these two growing seasons. [Conclusion] The application of chloramphetamine to rice fields did not affect the ecological function of parasitic natural enemies of the rice planthopper, and did not adversely affect non-target pests or parasitic natural enemies of the rice planthopper.
