Ongoing research

While Virginia creeper leafhopper egg clusters can be seen with the naked eye, in order to determine their status it is best to use a dissecting microscope with back lighting. What follows is a series of images that depict the various states of VCLH eggs.

Nupsyllid project A federal NIFA-CAPS grant was awarded to researchers in Florida, California, Texas and Arizona to develop a Nupsyllid. The goal of this research is to replace the wild type Asian citrus psyllid (ACP) insect vector with a population that is unable to transmit CLas.

Regenerating rooted plant and plantlet In citrus, the process of genetic engineering (cutting and pasting new information into the citrus genome) has been used experimentally to protect against citrus tristeza virus (CTV) and canker diseases, provide resistance to certain insects, create dwarf varie...
