Automated instrumentation sorts grain kernels and insects.
Agricultural and electrical engineers at the USDA-ARS Grain Marketing and Production Research Center, Engineering Research Unit in cooperation with entomologists and cereal chemists have developed an automated single-kernel trait-selection system. The system feeds single kernels to a viewing area where a near-infrared spectrum is collected. The system was originally developed to measure wheat quality characteristics, such as protein, hardness, vitreousness, fungal damage, toxin levels, and sprout damage from the NIR spectrum. Kernels are then sorted at a speed of about one kernel per second based on user calibrations. Applications of this technology include selecting specific grain traits, such as high protein content, from early generation breeder samples to aid in development of cultivars with specific attributes. The system is also being used to select specific traits from samples, such as kernels with specific hardness characteristics, to study environment and genetic affects on quality traits. Other applications include selecting specific quality traits, such as sprout damage or toxin levels, to potentially aid inspectors in determining grade criteria, including those relating to food safety. The system is also finding applications in other grains, such as sorting millet by starch levels and sorting sorghum by hardness. An additional application of this technology includes sorting tsetse fly tsetse fly (tsĕt`sē), name for any of several bloodsucking African flies of the genus Glossina, and in the same family as the housefly. pupae, which are about the same size as grain kernels, by sex. In fact, the first commercial application of this technology was to automatically sort tsetse fly pupae by sex so that males could be sterilized and females returned to rearing colonies as part of the Foreign Agriculture Organization, International Atomic Energy Agency International Atomic Energy Agency: see Atomic Energy Agency, International.

International organization officially founded in 1957 to promote the peaceful use of nuclear energy. , Sterile Insect Technique Sterile insect technique is a method of biological control, whereby millions of sterile insects are released. The released insects are normally male as it is the female that causes the damage, usually by laying eggs in the crop, or, in the case of mosquitoes, taking a bloodmeal fly eradication programs in Africa. The system was developed through the Cooperative Research and Development Agreement “CRADA” redirects here. For other uses, see CRADA (disambiguation).
