Heavy metals toxicity is a significant concern for primary consumers, like grasshoppers. In a lab setting, the effects of HgCl2, CdCl2, and ZnCl2 on egg hatchability and embryonic duration of Oxya hyla hyla and Oedaleus abruptus (Acrididae) species were investigated. The same-aged healthy eggs were incubated in sand that had been exposed to various quantities of the metals. When metal concentrations in both experimental species increased relative to the control, egg hatching considerably decreased. Similar patterns were also seen when looking at the length of the embryonic duration.
