BEMISIA-L Listserver

What is a list server? A list server is like on open conversation that travels through e-mail.  One person e-mails a question to a specific email address and it is sent to all on the list.  As people respond to the questions and statements they are e-mailed back to all on the list.  This is a good way to get questions answered and to learn about the many new species of whiteflies attacking plants in Florida. This list is not limited to Bemisia. In fact, we will probably concentrate on a number of newly introduced invasive species.

The following links are to photos of the site where we released the predatory beetle Nephaspis oculatus (links to videos of this beetle feeding on whiteflies are at the end of this page). All of the photos wer taken of the same tree.

This site was also treated twice with an insect pathogenic fungi which is sold as Preferal. The site was treated a few weeks prior to the release of beetles in February 22, 2012. You will note that the whitefly population continued to increase until June where we noted a significant decrease in whitefly numbers while the number of beetles had increased significantly.  On August 8, 2012 the whitefly the population appears to be increasing while only one beetle was observed.  We were told the trees had been treated with insecticide 2 weeks earlier.  There are many questions we have about what is actually going on at his site!

Note how there is a T-shaped rip in the exoskeleton which allowed the adult to emerge from the “body” of the fourth nymphal stage.

The eight photos above were taken in February of 2012 in Fort Lauderdale, Florida. The population was thriving with adults, nymphs and eggs on almost every leaf.

These photos were taken in May of 2012 and there were very few adult, nymphs or eggs on any of the foliage. The trees hadn't been treated and most of the nymphs we observed were parasitized.

Note how close this tree is to a body of water making treatment with insecticides almost impossible.

Infested plant material is often placed alongside the road where it is eventually picked up and placed in the back of a truck.  The truck drives to a landfill where the material is disposed of.  Currently, there are no efforts to prevent insects from escaping and infesting new plants along the route to the disposal site.

Rugose spiraling whiteflies that were killed by the parasite, Encarsia guadeloupae. Note the round emergence holes in the exoskeleton which allowed the adult wasp to emerge from the “body” of the fourth nymphal whitefly stage.  These were collected at Phipps Ocean Park in Palm Beach, FL (May, 2012).
