为筛选一种容易取材、价格低廉且诱食效果较佳的天然饵料,在野外测定了隆缘桉树皮、杉树皮和甘蔗渣三种饵料对黑翅土白蚁和黄翅大白蚁的诱食效果。结果表明在非选择性取食试验中,桉树皮、杉树皮和甘蔗渣在埋插后15 d的诱食率为84.26%、77.78%和8.33%;在选择性取食试验中,桉树皮、杉树皮和甘蔗渣在埋插后15 d的诱食率为87.04%、81.48%和9.26%。在两种试验条件下,桉树皮和杉树皮对两种白蚁均有较好的诱食效果,且两者之间的差异不显著,甘蔗渣对两种白蚁的诱食效果较差。
In order to screen a kind of natural food which is easy to be drawn, cheap and has good attractant effect, the bait of Eucalyptus bark, cedar bark and bagasse were measured in the field to attract the black termites and yellow-winged termites effect. The results showed that in non-selective feeding experiments, the edible rates of eucalyptus bark, cedar bark and bagasse were 84.26%, 77.78% and 8.33% respectively 15 days after burial; in elective feeding experiments, The catching rates of fir bark and bagasse 15 days after embedding were 87.04%, 81.48% and 9.26%, respectively. Eucalyptus bark and cedar bark had better attractant effect on both termites under the two experimental conditions, and the differences between the two species were not significant. Sugarcane bagasse was less attractive to the two termites.
