We’ve tailored this methodology to be executed simply on-farm, with provides you may get from Amazon or the Greenback Retailer.

You’ve Washed Out Some Thrips – Now What?
We’ve beforehand advocated for the usage of our easy thrips key for growers for figuring out thrips in your greenhouse (replace coming quickly!). Though we clearly suppose that is the bestest instrument of all time, we acknowledge it has numerous steps to get you to a remaining species identification. However typically you simply must know, IS IT PARVI OR NOT PARVI???
To reply this easy query, Ashely Summerfield (Vineland) and I developed a fast determination tree. We hope you prefer it!
To make use of the choice tree, you’ll nonetheless must see sure options on the thrips that may solely be seen at round 40X magnification. (So a daily hand lens isn’t going to chop it!). That is often executed with a dissecting microscope. (Want to purchase one? Take a look at our Information to Shopping for Microscopes!).
When you’re not able to put money into a microscope, you can even purchase this actually neat telephone attachment for beneath $50 CDN! It’s not good, but when the specimens are lifeless, and you utilize the built-in gentle function, the picture high quality is usually adequate to have the ability to see key options, like hairs on the pronotum (see the center image, under).
This hand lens positively not truly 200X magnification (regardless of its description). It’s extra like 35-40X, for my part. However in case you evaluate it with the picture taken with an precise microscope (far proper, under), it positively will get the job executed, particularly in comparison with a daily 20x hand lens (left picture).
Observe: If the hyperlink above doesn’t work, merely kind in “200x telephone microscope” into Amazon.ca’s search bar. We additionally plan to have a extra detailed weblog put up about microscope and hand lens choices within the close to future!
