1980 Fall Armyworm Symposium: Mechanical Infestation Device Used in Fall Armyworm Plant Resistance Programs

B. R. Wiseman, F. M. Davis, J. E. Campbell


A mechanical device called the "Bazooka" was developed by an entomologist of the Centro Internacional de Mejoramiemto de Maiz y Trigo (CIMMYT) for manually dispensing lepidopterous larvae. Modifications have been made to fit individual plant-resistance programs for infestations of fall armyworm, Spodoptera frugiperda (J. E. Smith), southwestern corn borer, Diatraea grandiosella (Dyar), and the European corn borer, Ostrinia nubilalis (Hubner). The implementation of this mechanical larval dispenser allows its use in the laboratory for rearing insects, in the greenhouse for infesting seedlings, and in the field for large or small testing purposes.
