Interspecific Attraction in Lepidoptera in the Field1

Abstract
Field tests were conducted to investigate interspecific attraction among lepidopterous species. In addition to attracting males of their own species, females of each species tested also attracted males of other species, some transcending superfamily lines. Female Indian meal moths, Plodia interpunctella (Hübner), and almond moths, Cadra cautella (Walker) (family Pyralidae) were attractive to male lesser cornstalk borers, Elasmopalpus lignosellus (Zeller) (also Pyralidae) in addition to male beet army worms, Spodoptcra exigua (Hübner), and to male Heliophana mitis (Grote), both Noctuidae. Beet armyworm and fall armyworm, Spodoptera frugiperda (J. E. Smith), females were attractive to lesser cornstalk borer and H. mitis males.
