Abstract
The purpose of this study is to develop a red fire ant pesticide spreader for ridge application to eliminate the damage of red imported fire ant（RIFA） on the bank. Based on a scriber for course, a suitable red fire ant pesticide spreader for ridge application is designed. The model is designed with a computer software－I-DEAS 8.0, which can analyze the stress, strain energy and deformation of the spreader’s model under various loading condition. According to the analysis, the largest deformation of the spreader’s model is 4.34mm.
On the other hand, in order to prove that the performance of the red fire ant pesticide spreader for ridge application is better than that of the scriber for course, both of them are tested by some spreading experiments, and the results are compared with each other. The tests reveal that the coefficient of variation（CV） of the red fire ant pesticide spreader for ridge application is smaller than that of the scriber for course, which means that the red fire ant pesticide spreader for ridge application can spread more uniformly than the scriber for course. The coefficient of variations of the exits on parallel are close, which means that the spread quantities of these two exits are close. Reducing the space of exits in advance can solve the problem of over-spreading.
