A mutant Colorado potato beetle, Leptinotarsa decemlineata (Say), with white-body and pearl-eye was isolated. Karyotype analysis showed that the No. 2 chromosomes of the mutant are of the acrocentric race. Reciprocal crosses of the mutant with a metacentric race of the wild type revealed that both the white-body and pearl-eye are due to single autosomal recessive genes that are not allelic but segregate independently from each other. The pericentric inversion of No. 2 chromosomes is a stable mutation that followed Mendelian segregations in the F2 hybrids. Hybrids showed normal meiotic pairing. Chiasma frequency analyses indicated that the female parent influenced the recombination value of the hybrids.
