Occurrence and genetics of black‐eyed migratory locusts, L ocusta migratoria ( O rthoptera: A crididae)

Black‐eyed L ocusta migratoria appeared in albino locusts as a result of crossing between a short‐winged strain originating from T sushima I sland, J apan, and an albino strain originating from O kinawa I sland. The black eye trait was recessive to the white eye trait because the crosses between black‐ and white‐eyed albino locusts produced only individuals with white eyes in the F 1 generation. In the F 2 generation, black‐ and white‐eyed individuals appeared in a ratio of 1:3, indicating that the black eye trait was controlled by a simple M endelian unit. The black eye trait showed no genetic association with other traits including wing morph, adult body dimensions and classical morphometric ratios such as hind femur length / head width and forewing length / hind femur length.
