Performance of selected lines of Trichopria drosophilae and of Ganaspis brasiliensis on different fruit

A few generations of laboratory selection can increase the developmental success of native parasitoids on invasive targets. However, for this approach to be used more widely for biological control we need to understand if the improved performance of native species, achieved under artificial laboratory conditions, translates to improved control in more natural environments. It is also unknown what the biocontrol potential of laboratory selected generalist native parasitoids may be compared to co-evolved specialists that are typically introduced for biological control of invasive species. To assess how rearing in artificial diet affected host finding ability in natural hosts we used laboratory selected (adapted) and non-adapted populations of the generalist native parasitoid Trichopria drosophilae to parasitize the invasive fly, Drosophila suzukii in three different fruit types. In a separate experiment, we compared the effectiveness of adapted and non-adapted populations of T. drosophila..., Collected in the laboratory., , # Performance of selected lines of Trichopria drosophilae and of Ganaspis brasiliensis on different fruit

Give a brief summary of dataset contents, contextualized in experimental procedures and results.

## Description of the data and file structure

In the first tab data for 'experiment 1' is given. The second tab contains data for 'experiment 2'.

Fruit experiment (first tab)
Column A: the fruit type used
Column B: the parasitoid treatment used
Column C: the number of parasitoid wasps used
Column D: the temporal block the treatments were tested, the two blocks are one week apart
Column E: cage number = replicate; in each cage there was fruit placed on the ground or elevated, hence two lines for each replicate
Column F: ‘up’ refers to fruit elevated and ‘down’ refers to fruit on the ground, for the control treatment no parasitoids were released therefore the position of the fruit during parasitism is n...
