Apple blotch leafminer trap captures

The average number of adult leafminers caught per trap in each monitored block. The averages are cummulative.
* Threshold = 8/trap by tight cluster or 21/trap by pink*

*I do not have a true threshold, but if I find more than a couple per 25 clusters I get nervous.*
