Are Paris greens suitable for killing the larvae of malarial mosquitoes?

Recently after our articles "Paris greens as a means of struggle against larvae of malarial mosquitoes" and "Parisergrün als Anopheles-Larvizid" there appeared 2 articles on the same subject by F. I. Yatsenko, in which the author, considering his experiments in laboratory and natural conditions quite convincing, advises to use Parisergrün instead of oil and kerosene on huge areas (calculations are made on tens!) and suggests that Parisergrün promises to displace all other larvicides. In view of the fact that our experiments published earlier as well as those which we made further do not give us the right to consider Paris greens as an excellent larvicide, we will dwell first on Yatsenko's experiments to clarify whether they really allow to draw conclusions about superiority of greens over kerosene and oil and then we will pass to description of our new experiments which did not give a difference with the previous ones.
