Patty,
I found some information about Whiteflies.It does mention Neem Oil and insecticidal soap among other things.It may help. Brady

Here is a link that might be useful: Whiteflies

Thanks, Brady. I have this bookmarked since I use UCIPM's site all the time. Great site for me, since I live in Calif, but good really for anyone trying to safely manage pests on fruit and berries.

Whatever you use, keep at it. Whiteflies recurr.

Whitefiles recently killed one of my tropical guava trees.

I had them under control a few years ago. Spraying the undersides of the leaves with a jet spray from a garden hose and then applying neem oil to the undersides of the leaves.

I got a little lazy and decided not to treat the tree at all last year. Thinking the the leaves were going to fall off in the winter anyways. That was a big mistake. The tree became diseased and unfortunately died.

Patty,

The entomologist guru at Texas A&M told me to use Imidicloprid, but the first thing he said to use, "that I would surely not find in Guatemala" was Centaur (Buprofezin).... after those two, Movento (Spirotetramat).
Organically, the natural pest control is a type of wasp that they have released in California in the melon growing areas... I'm sure you are better able than I to find out about that.
BTW, I learned a lot about Meyer lemons and harvest techniques in Santa Paula, CA... no thanks at all to the big boys, being Sunkist and Limoneira.
Hope the Easter Bunny was good to you

Thanks, John. I will check all out. And, I'd love to hear about your harvesting tips from Santa Paula. Are they growing Meyers up there? How interesting! Let us know about that over on the Citrus forum, I would be very interested in hearing about that.

Patty,

When I get all my trip info and fotos organized I will post some on the citrus forum.
