The action of bacterial insecticides based on Bacillus thuringiensis H-14 and B. sphaericus in a dose of 0.005-2 mg/l on the mermithids Romanomermis iyengari, R. culicivorax and R. jingdeensis was studied. It was shown that though bacterial agents suppressed mermithid preparasite larvae density about 30-40%, the survivors might invade 100% of mosquito larvae. The viability and fertility of adult mermithids did not change under the influence of bactoculicide in doses 5-50 times higher than those used against mosquitoes in practice. In combined field trials of sphaerolarvicide (1.5 kg/ha) and R. iyengari mermithids the infectivity of Anopheles sacharovi larvae reached 96%. Mermithids in combination with bactoculicide and sphaerolarvicide might be useful in integrated control systems because these bacterial agents are harmless for mermithids of all stages in doses useful against mosquito larvae.
研究了基于苏云金芽孢杆菌H-14和球形芽孢杆菌、剂量为0.005 - 2毫克/升的细菌杀虫剂对罗曼索线虫、嗜蚊索线虫和建德索线虫的作用。结果表明，尽管细菌制剂可使索线虫寄生前期幼虫密度降低约30 - 40%，但存活下来的索线虫仍可侵入100%的蚊虫幼虫。在比实际用于防治蚊虫的剂量高5 - 50倍的细菌杀虫剂影响下，成年索线虫的活力和繁殖力并未改变。在球形幼虫杀虫剂（1.5千克/公顷）与罗曼索线虫的联合田间试验中，萨氏按蚊幼虫的感染率达到了96%。索线虫与细菌杀虫剂和球形幼虫杀虫剂联合使用可能对综合防治系统有用，因为这些细菌制剂在对蚊虫幼虫有效的剂量下对索线虫的所有阶段均无害。
