Just saw the post by Patrina mentioning the use of yellow sticky cards and catching lots of thrips. I have read that thrips do prefer blue but if you have whitefly AND thrips go ahead and use the yellow.
But this has been my experience using sticky cards--you go down to the garden and marvel at the tons of bugs stuck on the card--
I took the card and looked under a high-powered microscope
and NO thrips. I am afraid I was just catching alot of harmless insects and beneficials as well.
But I have to say I have never seen alot of thrips on my plants even in the year I suffered heavily from TSWV.
So I was wondering do the rest of you really have a heavy infestation of thrips --so that you see them on all your plants. Have you looked at the cards (even with a 10x lens) to see what you are really catching?
