title: [The effect of exposure and feed on the results of the testing of bacterial insecticides on mosquito larvae].
abstract: It has been established that the duration of exposition and the availability of larval feed have a reliable effect on the index of insecticide activity (LC-50) of bacterial preparations as regards mosquito larvae. High degree of correlation between the results obtained in different conditions makes it possible to calculate the LC-50 values for any combination of exposition and feed availability, if an index for one of the combinations is known (the formula is presented). The proposed variant of test conditions (daily exposition without larval feed) ensures a more rapid achievement of the results and reduction in labour expenses.
