Carmine Mite in Strawberry

This one doesn't show too much in strawberry here on the Central Coast, so I was glad when the sample was brought in to me.  Complaint was fairly significant numbers of a reddish mite mixed together with a mess of twospotted mite. Are these going to cause a problem was the question.  Given that the carmine mites here are few in number and, as per the UC IPM website, tend to decline anyway as the temperatures warm in the spring, my call was to focus on the vast numbers of twospotted spider mite here.

I'm not going to restate the excellent information provided by colleague Shimat Joseph several years on the Salinas Valley Agriculture blog, so here is the link:
