In studies of five regions of the United States, we investigated the effect of region and urbanization on the occurrence and potential toxicity of dissolved pesticide mixtures. We analyzed 225 pesticide compounds in weekly discrete water samples collected during 6–12  ...

Whitegrubs are the key pests in Australian sugarcane, and, following severe damage in the 1990s, there was a concerted RD&E programme to develop and implement a broad-based approach to their management. Studies since the middle 2000s have added to the knowledge on their taxonomy, the ins ...
