Impact of predator diversity treatments on aphid prey density

Predator density and diversity were manipulated in a field cage experiment. <br><br>The data uploaded is the mean numbers and standard deviation of aphids (<i>R. padi</i>) at predator introduction and at the end of experiment 12 days later. <br><br>we had:<br>- Three low diversity treatments: carabid <i>P. melanariu</i>s, ladybird larvae <i>(C. septempunctata)</i>, lacewing larvae (<i>C. carnea</i>)<br>- A high diversity treatment using a subsitutive design
