As early as 1980 David B. Weissman began publishing the results of his field and laboratory studies of the Gryllus of the United States and Canada (Weissman et al. 1980). By 2003, David Gray had started his cooperation with Weissman by providing genetic analysis of the living Gryllus made available by Weissman's studies (e.g., Weissman, Walker, and Gray 2009). Weissman and Gray's results regarding the Gryllus of US and Canada are in ms and their target date for publication is May 2019. Their results will be made publicly available on SINA as soon as possible.
