Molecular interrogation of the feeding behaviour of field captured individual insects for interpretation of multiple host plant use.

The way in which herbivorous insect individuals use multiple host species is difficult to quantify under field conditions, but critical to understanding the evolutionary processes underpinning insect-host plant relationships. In this study we developed a novel approach to understanding the host plan...
