Use of the Cricket Embryo (Acheta domesticus) as an Invertebrate Teratology Model. Walton, B.T. (1983). Fundam. Appl. Toxicol 3: 233236. Embryos of the cricket Acheta domesticus (L.) have been shown by bioassay to develop gross morphological abnormalities after exposure to a number of complex organic mixtures as well as to display a critical period of teratogen sensitivity and an ability to metabolize xenobiotics during development. Because the assay is simple, inexpensive, short-term (less than two weeks), and objective, it could be useful as an in vivo screen in a hierarchical approach to teratogen detection. Further investigation of cricket embryo responses to known terato-gens is needed to establish the predictive value of this assay.
