Exposure to NaC1, KCI, and CaCl affected the entomopathogenic nematodes Heterorhabditis bacteriophora and Steinernema glaseri differently. Survival, virulence, and penetration efficiency of S. glaseri were not affected by these salts. At high concentrations, however, all three salts inhibited its ability to move through a soil column and locate and infect a susceptible host. Calcium chloride and KCl had no effect on H. bacteriophora survival, penetration efficiency, or movement through a soil column, but moderate concentrations of these salts enhanced H. bacteriophora virulence. NaCl, however, adversely affected each of these parameters at high salinities (>16 dS/m). Salt effects on S. glaseri are attributed solely to interference with nematode host-finding ability, whereas the NaCl effects on H. bacteriophora are attributed to its toxicity and possibly to interference with host-finding behavior.
暴露于氯化钠、氯化钾和氯化钙对昆虫病原线虫嗜菌异小杆线虫和格氏斯氏线虫的影响有所不同。格氏斯氏线虫的存活率、毒力和穿透效率不受这些盐类的影响。然而,在高浓度下,所有这三种盐都会抑制其在土壤柱中移动以及定位和感染易感宿主的能力。氯化钙和氯化钾对嗜菌异小杆线虫的存活率、穿透效率或在土壤柱中的移动没有影响,但这些盐类的中等浓度会增强嗜菌异小杆线虫的毒力。然而,在高盐度(>16 dS/m)下,氯化钠会对这些参数中的每一个产生不利影响。盐对格氏斯氏线虫的影响完全归因于对线虫宿主寻找能力的干扰,而氯化钠对嗜菌异小杆线虫的影响则归因于其毒性以及可能对线虫宿主寻找行为的干扰。
