| Popis: | Nine-year data were collected to analyze the occurrence of rice planthoppers in diversified farming on Chongming Eco-Island in China from 2006 to 2014, the most important pests of rice in agroecosystems. We found a significantly linear decrease in the average numbers of adult rice planthoppers trapped per light trap per day. Using quadratic regression polynomial analysis we concluded that four meteorological indicators (average daily temperature, daily rainfall, sunshine duration, and average daily wind velocity) had significant effects on the numbers of brown planthopper ( Nilaparvata lugens ) and white-backed planthopper ( Sogatella furcifera ) trapped in the lamp, and that average daily temperature had a significant effect on the number of small brown planthopper ( Laodelphax striatella ) trapped in the lamp. These findings suggest that increasing temperature related to climate change might promote the occurrence of rice planthoppers in diversified farming in the future. |
