	Csr interacts with for, more specifically fors homozygous larvae behave as rovers in the presence of one Csr allele. (Sokolowski et al., 1995) A third chromosome modifier of for that increases the foraging path lengths of fors larvae. (Varnam and Sokolowski, 1995) One allele of Csr interacts with fors homozygous larvae to produce rover behaving larvae. (Burgess et al., 1994)
