The superfamily Cercopoidea, some members of which are called froghoppers and still others known as spittlebugs, are a group of hemipteran insects in the suborder Auchenorrhyncha. Adults are capable of jumping many times their height and length, giving the group their common name, but many species are best known for their plant-sucking nymphs which produce foam shelters, and are referred to as "spittlebugs".
The Xanthomonadales are a bacterial order within the Gammaproteobacteria. They are one of the largest groups of bacterial phytopathogens, harbouring species such as Xanthomonas citri, Xanthomonas euvesicatoria, Xanthomonas oryzae and Xylella fastidiosa. These bacteria affect agriculturally important plants including tomatoes, bananas, citrus plants, rice, and coffee. Many species within the order are also human pathogens. Species within the genus Stenotrophomonas are multidrug resistant opportunistic pathogens that are responsible for nosocomial infections in immunodeficient patients.
Xylella fastidiosa is an aerobic, Gram-negative bacterium of the genus Xylella. It is a plant pathogen, that grows in the water transport tissues of plants and is transmitted exclusively by xylem sap-feeding insects such as sharpshooters and spittlebugs. Many plant diseases are due to infections of X. fastidiosa, including bacterial leaf scorch, oleander leaf scorch, coffee leaf scorch (CLS), alfalfa dwarf, phony peach disease, and the economically important Pierce's disease of grapes (PD), olive quick decline syndrome (OQDS), and citrus variegated chlorosis (CVC). While the largest outbreaks of X. fastidiosa–related diseases have occurred in the Americas and Europe, this pathogen has also been found in Taiwan, Israel, and a few other countries worldwide.
Philaenus spumarius, the meadow froghopper or meadow spittlebug, is a species of insect belonging to the spittlebug family Aphrophoridae. In Italy and America, it is economically important as one of the vectors of Pierce's disease.
Philaenus is a genus of insects belonging to the family Aphrophoridae, the spittlebugs.
The Aphrophoridae or spittlebugs are a family of insects belonging to the order Hemiptera. There are at least 160 genera and 990 described species in Aphrophoridae.
Aphrophora is a genus of spittlebugs in the family Aphrophoridae. There are at least 80 described species in Aphrophora.
Verrallia aucta is a species of fly in the family Pipunculidae. It is found in the Palearctic.
Carystoterpa fingens, commonly known as the variegated spittlebug, is a spittlebug of the family Aphrophoridae. It is endemic to New Zealand.
Aphrophora gelida, the boreal spittlebug, is a species of spittlebug in the family Aphrophoridae. It is found in North America.
Aphrophora saratogensis, the Saratoga spittlebug, is a species of spittlebug in the family Aphrophoridae. It is found in North America.
Aphrophora cribrata, the pine spittlebug, is a species of spittlebug in the family Aphrophoridae.
Lepyronia angulifera, the angular spittlebug, is a species of spittlebug in the family Aphrophoridae. It is found in the Caribbean Sea and North America. Host plants for nymphs include Sporobolus indicus and Cyperus swartzii. They prefer fen habitat.
Philaronia abjecta is a species of spittlebug in the family Aphrophoridae. It is found in Central America and North America.
Aphrophora quadrinotata, the four-spotted spittlebug, is a species of spittlebug in the family Aphrophoridae. It is found in North America.
Neophilaenus is a genus of spittlebugs in the family Aphrophoridae. There are about 10 described species in Neophilaenus.
Lepyronia gibbosa, known generally as the hill-prairie spittlebug or great plains spittlebug, is a species of spittlebug in the family Aphrophoridae. It is found in North America.
Aphrophora princeps, the cone spittlebug, is a species of spittlebug in the family Aphrophoridae. It is found in North America.
Epipygidae is a lineage of froghoppers in the insect superfamily Cercopoidea. There are at least three genera and about five described species in Epipygidae, found in the American tropics. In addition, there are more than 20 undescribed species in the family. Molecular analyses indicate that the group is monophyletic, but is clearly nested within the family Aphrophoridae and is probably best relegated to the status of a subfamily or tribe, rather than retained as a separate family.
Pecan bacterial leaf scorch is a disease of the pecan tree that is common throughout the production regions of the United States caused by the pathogenic bacterium Xylella fastidiosa subsp. multiplex. The pathogen was initially discovered to be coincidentally associated with symptoms of pecan fungal leaf scorch in 1998 and has subsequently been found to be endemic in the southeastern United States, as well as Arizona, California, and New Mexico.
