Results from a bitter gourd orchard at Lutsao, Chiayi in 2006 showed the average captured female and male melon files from the 0.02% Spinosad-treated plot (8x), were significantly lower than the numbers captured from surrounding area. The average percentage of fruit damage and percentage infestation of non-paper-bagging bitter gourd were only 19.2% and 4%, respectively, in the treated area that were significantly different from the percentage of no bait check. The average number of captured melon files from the Spinosad treated plot in a screenhouse at Hsichou, Changhwa were 0.1 females and 0 male while in the pretest they were 9.3 females and 7.3 males. The average percentage of fruit damage and percent infestation for non-paper-bagging fruits were 0.9% and 0.1%, respectively, in the screenhouse. In addition, the averaged percent infestation was only 34.7% from the Spinosed-treated plot in a special sponge gourd producting area with high melon fly population at Tounan, Yunlin and the averaged control rate was up to 50% for the melon fly. In conclusion, the Spinosad bait exhibit a significant control to the melon fly and is of great potential in its application. |
