Dipterous blood-sucking insects (horseflies, black flies, gnats, midges) have negative impacts on the performance of draught horses in forest enterprises. For the protection of these animals, the following preparations were applied at the interval of 24 hours: diethyltoluamide, Oxamat (N,N-diethyloxamine acid, USSR) and Stomoxin (synthetic pyrethroid, product of the firm Wellcome, England). In the course of 66 working days, the performance of test animals treated with 10% water emulsion of diethyltoluamide increased by 49.25 cu. m. of skidded wood, i.e. by 0.74 cu. m. wood per horse/day (21.65%), as compared with the control group. The daily savings of prime costs per test horse/day made 16.99 Kcs (Czechoslovak crowns). In comparison with the control group, the performance of horses treated with 5% water emulsion of Oxamat increased by 85.50 cu. m. wood, i.e. by 1.29 cu. m. wood per horse/day (38.00%). Stomoxin at the concentration of 0.05% acted as a good insecticide but had no marked repellent effect. The results of this study document that the production of effective repellents should be introduced in the Czechoslovak Socialist Republic.
双翅目吸血昆虫（马蝇、蚋、蠓、摇蚊）会对林业企业中役用马的工作效率产生负面影响。为保护这些动物，每隔24小时使用以下制剂：避蚊胺、奥沙马特（N,N - 二乙基草氨酸，苏联）和斯托莫辛（合成拟除虫菊酯，英国威康公司产品）。在66个工作日期间，与对照组相比，用10%避蚊胺水乳剂处理的试验动物的工作效率提高了49.25立方米集材量，即每匹马每天增加0.74立方米木材（增长21.65%）。每匹试验马每天的直接成本节约为16.99捷克克朗。与对照组相比，用5%奥沙马特水乳剂处理的马匹的工作效率提高了85.50立方米木材，即每匹马每天增加1.29立方米木材（增长38.00%）。浓度为0.05%的斯托莫辛是一种良好的杀虫剂，但没有明显的驱避效果。这项研究的结果表明，捷克斯洛伐克社会主义共和国应引入有效驱避剂的生产。
