Several genera of psyllids, especially among the Australian fauna, secrete coverings called "lerps" over their bodies, presumably to conceal them from predators and parasites.

Due to the spread of citrus greening worldwide and the growing importance of psyllid-spread diseases, an International Psyllid Genome Consortium was established.

[4] Insect genomics provides important information on the genetic basis of the pest's biology which may be altered to suppress psyllid populations in an environmentally friendly manner.

Thus far, 10 microbial organisms have been identified within these psyllids, among them the primary endosymbiont, whose genome has been sequenced and posted at the NCBI database, as well as a Wolbachia species.
