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.
Today, Drew Dyes from PFS and I are surveying citrus groves in Southwest Florida. This past week, I covered about 500 miles looking at groves around the state. I’ll update this post later with more photos and details, but generally, trees are looking better than they did the last two years on a similar drive.
Recently, I released a new version of Tamarixia Tracker that works in the Cloud. Here’s a quick little FileMaker script I added to make the app “iOS aware”. What this means is the app will detect your device (desktop, iPad or iPhone) and adjust it’s screen size and resolution for your device. The code from the Filemaker site is in the image.
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 started collecting tissue sample this week. This will help us work out the optimum nutrition program for the trees. Depending on these results, we might also start soil tests, too. These are the hands of Drew Dyess from Plant Food Systems, who is helping out.

No one likes a good mobile app more than I. I think I have about 200 apps on my iPhone and iPad. Somehow, I seem to use most of them often. This includes apps like SoilWeb, Planimeter and four or five weather apps. However, there are times when I just need to write something down quickly, such as when a call comes in from the grove on something that needs to be acted upon right away. In these cases, I might not have time to whip out the PDA, turn it on, enter the passcode, start an app, get the type screen called up, and start typing away.
In these instances in the past, I’d jot something on a piece of paper lying around, or in an increasingly disorganized notepad. But I eventually worked out a better way. I call this, the GroveDex™ system. GroveDex™ is a PIM (personal information management) system that uses 3×5 index cards specially designed to handle the kind of grove information I have to use every day. In this post, I’ll show you what GroveDex™ is, and how you can even adapt it for your own use. In a second post to follow, I’ll show you a companion system that I call, “GroveMod™ PIM, which is based on the popular PocketMod technique for carrying ready-to-access information in your pocket.

Several days ago, we noticed that fruit and leaf drop are beginning again. From what I can gather, this might be some of the first of the season, at least in our area in Central Florida. This is the same sort of drop we’ve seen the past couple of years at about this same time. It’s hard to pin down a cause, but it seems the fruits and leaves most affected by this drop are affected with greening symptoms. Here’s a quick drive through video of several trees to give you a general idea what we’re seeing in the groves. The video is after the jump.

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.
