目的研究能有效防治白蚁的盐土种类和浓度。方法采用不同种类、不同浓度的盐土,对白蚁进行阻杀、致死和抗穿越效果实验。结果由粗盐、细盐和混合盐制成的盐土对白蚁均具有一定的阻杀效果,其阻杀效果与实验浓度呈正相关趋势,混合盐效果最差;台湾乳白蚁和黑翅土白蚁在0.4%及以上浓度的盐土中100%死亡的平均时间分别在25.33 d和5.67 d以下;台湾乳白蚁在浓度为0.4%的盐土中平均修筑了28.47 cm长的蚁路,最终因接触盐土而死亡。结论盐土对白蚁具有一定的阻杀、致死效果和抗穿越能力,其中粗盐和细盐对白蚁的阻杀效果优于混合盐,阻杀效果的好坏与土中盐的浓度有关,0.4%浓度的盐土对白蚁具有较好的致死效果和抗穿越能力。
Objective To study the types and concentrations of salt soil that can effectively control termites. Methods Different types and concentrations of saline soil were used to kill and kill termites. Results The saline soil made from coarse salt, fine salt and mixed salt had certain resistance to termites, and the blocking effect showed a positive correlation with the experimental concentration, the mixed salt had the worst effect. The termites of Taiwan and black-winged termites The average time of 100% death in salinity of 0.4% and above was below 25.33 d and 5.67 d, respectively. On average, the termites of Taiwan produced 28.47 cm long ant road in saline soil with a concentration of 0.4% and eventually died of salt soil contact . CONCLUSION Saline soil has some effects of killing, lethal effect and anti-traumatic effect on termites. Among them, crude salt and fine salt show better resistance to termites than mixed salt, and their effect is related to the concentration of salt in the soil. 0.4% Salt concentration of termites have better lethal effect and anti-traversal ability.
