MONITORING TRACE ELEMENTS IN DIETS AND LIFE STAGES OF THE ONION MAGGOT, HYLEMYA ANTIQUA (DIPTERA: ANTHOMYIIDAE), WITH X-RAY ENERGY SPECTROMETRY1
Published online by Cambridge University Press: 31 May 2012
Abstract
Elemental profiles of onion maggots reared on a dried carrot based medium were monitored by X-ray energy spectrometry. Adult insects had higher levels of S, Fe, Cu, and Zn and lower levels of Cl, K, Br, and Sr than were apparently present in the medium. Addition of Rb to the larval diet resulted in a higher than normal concentration of Rb in the newly-emerged adults. This concentration of Rb decreased to ambient levels after 10 days. When Y was added to the rearing medium, it was not incorporated into the adult flies. Pupae from the Ga-supplemented diet failed to mature. The elemental profiles of male and female adults from the Rb- and Y-rearings differed significantly from the control rearings and each other. X-ray energy spectrometry shows much promise in helping define and monitor mineral requirements in insects.
