Characterization of a mutation in the eyes of the natural enemy Orius laevigatus (Hemiptera: Anthocoridae)

Abstract: Orius laevigatus (Fieber) (Hemiptera: Anthocoridae) is a key predator in biological
control programs in protected crops, used primarily to control thrips. The eye color of adults of this natural enemy is dark (garnet to black). However, adults with a bright red eye color have been found in a mixture of wild populations, easily recognizable from the rest of the individuals of the species. From these adults, a population carrying this eye mutation was established. Genetic analysis determined that the mutation (red) was controlled by a single autosomal recessive allele. The use of this red-eyed mutant strain could be useful as a visible marker for ecological and biological studies.
