Mechanical Infestation Device Used in Fall Armyworm Plant Resistance Programs

Abstract
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 were made to fit individual plant resistance programs for infestations of fall armyworm, S. frugiperda (J. E. Smith), southwestern corn borer, Diatraea grandiosella (Dyar) and the European corn borer, Ostrinia nubilalis (Huebner). The implementation of this mechanical larva 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.
