Chernyshevsky is still taught in schools, even in A-level History in England. His ideas are used in the A-level to show an evolution in Russian revolutionary thought from focussing on a rural revolution, to focussing on an urban one.
If you look at JSTOR a simple search can be filtered by date, so from 1991 to 2010 a search of 'Chernyshevsky revolution' yields 190 results, while from 1971 to 1990 it yields 329. If really interested in the question you would want to examine the material qualitatively in more detail but that suggests that academic interest has lessened. At first glance this looks a little faster than might be accounted for simply by decreasing relevance due to the passage of time, so perhaps there has been a re-evaluation in some subfield.
