Abstract

The Lotka-Volterra cubicdifferential systems with (1:-2)-singularity possessing invariant
straight lines of two direction and total multiplicity six are classified. There are obtained fifteen distinct
classes modulo the affine transformations and time rescaling. The Darboux first integrals are constructed
