Abstract:

In order to improve the quality of Xishuangbanna rice and reduce pesticide residues, how to control pest scientific and rationally became an important method. Frequency-vibrancy pest-killing lamp is a widely used in the area of physico-kill pest, of which characteristic was broad-spectrum, high performance and pollution-free. In this paper, we divided it into four areas, which were light with non-pesticide, light with pesticide, non-light with pesticide, non-light with non-pesticide; applied randomized block experiment, investigated pest dynamics, carried out prevention and cured with chemical pesticide and tracked measurable yield timely. The results showed that, frequency insect light attracted insects volume between 6.7 g to 224 g of single lamp per night, light with non-pesticide, light with pesticide, non-light with pesticide and compared non-light with non-pesticide, control efficiency that were controlled major pests in rice of rice planthoppers and stem borer to achieve a significant level. Also, in this paper, we mastered the control efficiency of frequency-vibrancy pest-killing lamp to rice pests preliminary, reflecting the reduction occurred in rice pest control cost reduction and rice yield income and other aspects of the more significant outcomes.
