LX混配制剂对黄胸散白蚁Reticulitermesflavicps（Oshima）的药效，经实验室多次重复试验表明：200ppmLX混配制剂击倒速度比10000ppm氯丹快；24小时校正死亡率LX混剂200ppm为97．05％、氯丹10000ppm为97．45％。采用25％LX乳油作灭治白蚁现场试验，使用有效浓度为2500—3000ppm，用LX2500ppm浓度处理松木块作了对三种白蚁18个处理的预防试验。经三年多来的连续查访结果均获良好的防治效果。但防治效果能维持多久，有待进一步连续观察和残留测试。
LX mixed formulation on the yellow termite Reticulitermesflavicps (Oshima) efficacy, the laboratory repeated tests showed that: 200ppmLX mixed formulations knockdown rate faster than 10000ppm chlordane; 24-hour corrected mortality rate LX mixture 200ppm 97 .05%, chlordane 10000ppm is 97.45%. Field trials using 25% LX EC as off-season termites resulted in 18 trials of treatment of three termites with effective concentrations of 2500-3000 ppm treated pine wood at LX2500 ppm. After more than three years of continuous visit results have been good control effect. However, how long the control effect can last for further continuous observation and residue testing.
