“…We applied the Abbott's formula to correct the knockdown rates for testing the toxicity of each insecticide [28] and then transformed them to Probits [29] for linear regression analysis and the determination of 50% knockdown (KDT 50 ). For Probit analysis, we used GraphPad Prism version 7.00 for Mac (La Jolla, CA, USA).…”

The aim of the study was to determine the level of insecticide resistance and diversity in Anopheles mosquitoes in northern Uganda. Standard WHO insecticide susceptibility test assays were used to test for susceptibility to 0.5% malathion, 0.1% bendiocarb, 0.05% deltamethrin and 0.75% permethrin on 3-5 day old generation one progeny. We also screened for species diversity and knockdown resistance using PCR assay. Results: Anopheles gambiae s.s. is the predominant malaria vector in northern Uganda followed by An. arabiensis. An. gambiae s.s. was susceptible to malathion and bendiocarb with the observed mortality rate of 100% and 98-100% observed respectively while very high resistance was observed with deltamethrin and permethrin. Minimal KDReastern variant homozygous forms of 8.3% in An. gambiae s.s. were detected in Oyam district. In conclusion, this study confirms that An. gambiae s.s. females are susceptible to malathion and bendiocarb while high intensity of resistance was observed with deltamethrin and permethrin in the same area. Use of carbamate and organophosphate insecticides bendiocarb and malathion for indoor residual spraying activities in northern Uganda is highly recommended since high levels of pyrethroids resistance (deltamethrin and permethrin) was detected in the area.

Goal of the research is to consider the main concepts used in the probit-analysis method, the features of its application to determine the toxicity of pesticides, in particular insecticides, acaricides and fungicides. Methods. To determine the toxicity of pesticides, the method of probit-analysis was used. It consists in determining the dose of a substance necessary to achieve a certain level of mortality of test organisms, based on the transformation of the S-shaped «dose-effect» curve into a straight line. Results. The article describes in detail the main stages of probit-analysis: selection of biological material; determination of the pesticide dose range to be used and preparation of working solutions; processing of biological material; assessing the mortality of the studied objects; processing of the obtained results. The peculiarities of its use in determining the toxicity of insecticides and fungicides of different chemical groups and with different mechanisms of action are shown. As an example, the application of the method for determining the toxicity of insecto-acaricide Vertimek 018 EC against the spider mite (Tetranychus urticae Koch.) is given. Conclusion. The results of the research show the effectiveness of the probit-analysis method in determining the toxicity of pesticides, the possibility of its application for assessing the sensitivity of pests and pathogens to pesticides, and monitoring of their resistance.
