Last week, we reached a milestone in our Tamarixia release program–200,000 wasps released! Tamarixia is a parasitic wasp species that attacks citrus psyllids, which transmit greening disease. We’re interested in establishing Tamarixia in our area to help cover the declining backyard citrus trees that are difficult to treat for psyllid control by other means. We keep track of our wasp releases using our own iPhone app we developed (Tamarixia Tracker) to GPS and photograph each release.
We participate with the State of Florida in a program to release wasps that attack citrus psyllids, which transmit greening disease. Several months ago, I wrote an app to help us collect and organize the data. Well, this week, I’m happy to announce our wasp app, Tamarixia Tracker, is now in the Cloud! This cuts down on our administration time, and now we can report our wasp data back to the Dundee lab in real-time. Check out the video after the jump to see how it works!
We completed our Tamarixia work this week and we’re now at 177,400 wasps released! We’re pleased with the way this project is going.Our custom app, Tamarixia Tracker, helps us get the information back to the state quickly. In fact, we often have our report data tabulated and sent to the state within an hour or so of completing our release work. Here’s a sample report if you’re interested checking out our results.

Abandoned trees in backyards can be a risk to nearby commercial citrus groves. This is because abandoned trees may have psyllids that are not being controlled. These psyllids can spread to nearby commercial plantings and infect them with citrus greening disease.

This is an example of the feather flush where you find a lot of psyllids in citrus trees. You have to check these leaves carefully, because young psyllids are difficult to see with your naked eye.

Using the tap method for psyllid sampling. This is a good way to estimate the numbers of adult Asian citrus psyllids in a citrus grove. You can find more info on this technique from University of Florida IFAS Extension.
