The use of model objects in evaluating the effectiveness of DEET-based repellent agents for individual protection against blood-sucking arthropods

With the aim of unifying and simplifying the assessment of categories of the effectiveness of the repellents funds audited 473 studies 245 samples of repellent remedies on the basis of DEET in various formulations, made in 1995–2019 employees of the Scientific Research Disinfесtology Institute in laboratory and in field conditions. The experiments were conducted in parallel with the standards of the corresponding or expected categories of effectiveness of repellent remedies. The concordance of the results of standard laboratory experiments on a model object Ae. aegypti mosquitoes and the results obtained from testing repellent agents against natural populations of flying blood-sucking insects and taiga ticks is proved. The effectiveness of repellent remedies based on other repellent substances, as well as the effectiveness against other species, should continue to be investigated in full-scale conditions for individuals of natural populations. These remedies should be included in the system of categories of effectiveness of repellent products.
