摘要
目的 研究7种磷酸盐对散白蚁取食偏好性的影响.方法 通过选择取食实验筛选出对白蚁取食纤维素有较强促进作用的磷酸盐及其最佳添加浓度,然后通过无选择取食实验测定白蚁对添加这些磷酸盐的纤维素的取食量.结果 在选择取食试验条件下,7种磷酸盐均能不同程度促进白蚁取食,促进取食的效果与其浓度密切相关.促进取食效果最好的4种样品分别是含0.12％K2HPO4、0.09％Na4P2O7、0.18％Na4P2O7和0.46％K2HPO4的纤维素,取食量分别是参照的7.83、7.64、6.33和5.15倍;在无选择取食条件下,白蚁对添加磷酸盐的纤维素的取食量与对照无显著差异.结论 磷酸盐对白蚁取食纤维素有明显的影响,添加磷酸盐虽然在无选择取食条件下并不会明显增加白蚁对纤维素的取食量,但是在选择取食条件下能明显提高白蚁的取食偏好性,特别是K2HPO4和Na4P2O7,效果最为明显.
Abstract
Objective To study the effect of 7 phosphates on feeding preference of Reticulitermes speratus.Methods The phosphates and their optimal concentration with better promoting effect on termite feeding were selected through choice feeding trials,and consumption of the phosphate samples of termite was then tested by no choice feeding trials.Results The choice feeding trials showed that all the 7 phosphates could promote feeding preference of termites to different degrees,the promoting effect was closely related to their concentration.The cellulose containing 0.12％K2HPO4,0.09％Na4P2O7,0.18％Na4P2O7 and 0.46％K2HPO4 were most effective,and the consumption was 7.83,7.64,6.33 and 5.15 times of the control,respectively.The no choice feeding trials showed that there was no significant difference between the consumption of phosphate samples and the control.Conclusion Phosphate has a significant effect on the feeding preference of termites.Although the consumption of phosphate samples did not significantly increased under no choice feeding conditions,the feeding preference of termites could be significantly improved under choice feeding conditions,especially K2HPO4 and Na4P2O7 showing the most effective.
