Abstract:Melitara junctolineella Hulst (Order Lepidoptera, Family Pyralidae), one of the several insects introduced into Australia in connection with the attempt biologically to control the prickly-pear pest, is indigenous to North America. In southern Texas it produces two generations annually. Its brood adjustment to seasons was upset by departure from our winter and immediate entry into the summer of the Southern Hemisphere. During the period it has been accomplishing its swing-over to the opposite seasons of Australia three generations have been produced in sixteen months. Complete adjustment to the Australian seasons has not yet obtained but observations indicate that in its ultimate adaptation to the opposite seasons it will have three broods yearly.
