hippelates is a genus of flies in the family chloropidae and are often referred to as eye gnats or eye flies ( the name is also used for members of the old world genus siphunculina ) .

they are very small ( 1.5 – 2.5 millimetres or 0.06 – 0.10 inches long ) flies that frequently congregate around the eyes to lap at the fluids .

they are primarily a nuisance pest , and do not bite .

they have been linked with the spread of bovine mastitis in north america , and in certain tropical regions , they are capable of vectoring disease-causing bacteria ( e.g. , yaws ) .

hippelates pusio is considered to be the vector for anaplasmosis , bovine mastitis , and haemophilus spp. which cause bacterial conjunctivitis or ' pinkeye ' .

hippelates

lioppelates pusio was first named hippelates pusio by loew in 1872 , and liohippelates bishoppi was described by sabrosky as hippelates bishoppi in 1941 . in 1929 , duda described the genus liohippelates , which now contains the most important common species of eye gnats in the southeastern united states including what was hippelates pusio and hippelates bishoppi .

during 1961–62 four hymenopterous parasites of the eye gnat , hippelates collusor ( townsend ) , were discovered in the semiarid agricultural regions of southern california . these parasites were found by field - exposing host hippelates pupae for several days between discs of nylon bolting cloth for predator protection . three of the parasites , phaenopria occidentalis fouts , spalangia drosophilae ashmead , and eupteromalus nidulans thomson , were successfully cultured in the laboratory and also studied in field releases . the fourth , trichopria n . sp . , died before propagation could be attempted . in field releases of parasites s . drosophilae was the most efficient species in seeking hippelates pupae in the environments studied .

hippelates probably contribute to the rapid spread of streptococci throughout the island , and to the frequency of infection with more than one serotype ; they may also contribute to the high incidence of streptococcal skin infection , but this requires further evidence .
will fly predators work for hippelates species , i . e . eye gnats ? these are flies , and they breed in rotting organic matter . but elsewhere in your q & r section it is said that fly predators do not work for any kind of gnat .

an epidemic of acute glomerulonephritis in trinidad led to an investigation into streptococcal skin infection , as most nephritis cases were associated with this . hippelates in this region commonly feed on skin lesions , infected or otherwise . some of these flies captured in the vicinity of infected children were found to be contaminated with streptococcus pyogenes ; 3 species were involved , h . peruanus , h . flavipes and h . currani . the naturally - acquired infection lasted for 28 hours or more , and the flies would return to human bait while still infectious . the hippelates population and the streptococcal skin infection rate at one school showed similar changes .
the eye gnats , a genus of flies in the family chloropidae ( fruit flies ) that are attracted to the bodily secretions and fluids of animals and humans , particularly those in the eyes . hippelates is suspected of transmitting certain types of conjunctivitis ( such as pinkeye ) , bovine mastitis , and yaws ( frambesia tropica ) .
unfortunately the fly predators do not work on hippelates . primarily the fly predators are for flies in the muscidae family , though they will occasionally parasitize those in the calliphoridae and sarcophagidae families . their very limited host range makes them ideal for biological control as they do not pose a risk to non - pest species ; unfortunately , it also means they are unable to control every pest species of fly .
predatory and scavenger arthropods were surveyed in hippelates collusor ( townsend ) breeding habitats in southern california by using 3 collection methods . a total of 117 different species was collected . the importance of potential predatory species is discussed , and various intensities of natural predation are recorded . there was considerable heterogeneity in predatory activity as influenced by locality , habitat , and seasonal and hourly differences . eggs and 1st - stage larvae sustained the highest predation , with a substantial amount being associated with teneral adults after pupal eclosion .
both liohippelates spp . and closely related hippelates spp . occur throughout much of north america ( sabrosky 1941 ) and 270 species have been described ( sabrosky 1987 ) . bingham ( 1941 ) determined during his investigations of liohippelates in the southeastern u . s . that liohippelates pusio was the most common pest of this genus . later that year , sabrosky ( 1941 ) found and described a new species , liohippelates bishoppi , misidentified by bingham as liohippelates pusio , which made up a moderate portion of the southeastern liohippelates .
physical barriers , such as screened porches and windows on houses and fly masks or fly sheets ( which resemble a fine cloth mesh , largely impenetrable by even the smallest pests ) on livestock , can provide some relief from annoyance and protection from possible pathogen transmission . sanitation methods to eliminate potential breeding sites , such as reducing manure and organic matter in soil and reducing loose soil matter , may reduce breeding at the location . however , often reducing liohippelates and hippelates breeding sites is nearly impossible in livestock facilities as manure , moisture and soil disturbance are inseparable from animals .
members of the genus liohippelates , formerly hippelates , are very small true flies and a common occurrence in much of north and south america ( sabrosky 1980 , kumm 1935 ) . these non - biting pests are attracted to fluids secreted by the eyes , nose and ears on both humans and animals . some species are attracted to discharge from open wounds and excrement ( goddard 2007 ) . because of their propensity for hovering around the eyes , this genus has been referred to commonly as eye gnats , but are also known as grass flies , eye flies , and fruit flies .
in 2006 114 people were examined in santa catalina and san joaquin ; 21 patients were clinically diagnosed with trachoma ( 18 . 4 % ) , 15 ( 13 . 2 % ) of them children under 15 years old . all trachoma phases were observed . three women had corneal opacity with poor vision . in the remaining three communities , three women with advanced trachoma with corneal opacity and blindness were detected . the poor quality of living conditions without fresh water and adequate sanitary disposal systems , and the abundance of flies identified as hippelates sp . , are risk factors for the transmission of the disease .

integrated pest management ( ipm ) is a sustainable approach to managing pests that combines multiple approaches including prevention , avoidance , pest monitoring and suppression in a manner that minimizes public health , economic , and environmental risk . ipm serves as a framework to provide an effective , comprehensive , low - risk approach to protect people and resources from pests .
ultimately , the goal with an ipm program is to help stakeholders deal with pests—insects , plant diseases , weeds , and more—with methods that reduce risks to public health and the environmental while saving money .
the north carolina extension ipm program serves as a focal point for team building , communication and stakeholder participation in integrated pest management ( ipm ) within the state . program goals include promoting effective and economical management of pests , reducing risks to human health from pests and pest management practices , and minimizing environmental effects through the adoption of ipm on a variety of crops and settings in north carolina . these goals are achieved by the timely delivery of ipm technology and research information to stakeholders in all regions of the state .
leadership of the extension ipm program in north carolina is provided by an ipm coordinator ( designated by the director of the north carolina cooperative extension service ) , an established advisory board , and working groups . dr . danesha seth carley , the current ipm coordinator , accepted the nc ipm coordinator position in 2013 .
the extension ipm coordinator involves faculty and staff from north carolina state university and north carolina a & t state university in ipm activities across the state , communicates program successes , and maintains stakeholder input via the advisory board and the ipm portal , as well as multiple training sessions and meetings .
the advisory board provides advice to the extension ipm coordinator regarding the direction of the ipm program in the state . it is composed of a wide variety of ipm stakeholders , including north carolina state university and north carolina a & t state university faculty , non - governmental agencies , environmentalists , north carolina department of agriculture & consumer services personnel , farmers and agricultural consultants .
the north carolina extension ipm program focuses on delivering ipm content to our stakeholders and community members through a variety of activities . the primary activities include information delivery , pest monitoring and data managment , evaluation and needs assessment tools development , and programs to magnify statewide ipm impacts .
the extension ipm program is a cooperative effort of the usda nifa , north carolina cooperative extension service , north carolina state university , and north carolina a & t state university . it also works in partnership with the southern ipm center , located at north carolina state university in raleigh , and acts to promote ipm in north carolina and the southern united states .
funding for the north carolina extension ipm program is provided by competitive grants from the u . s . department of agriculture’s national institute of food and agriculture ( nifa ) .
nc state university and n . c . a & t state university work in tandem , along with federal , state and local governments , to form a strategic partnership called n . c . cooperative extension , which staffs local offices in all 100 counties and with the eastern band of cherokee indians .
nc state university and n . c . a & t state university are collectively committed to positive action to secure equal opportunity and prohibit discrimination and harassment regardless of race , color , national origin , religion , political beliefs , family and marital status , sex , age , veteran status , sexual identity , sexual orientation , genetic information , or disability .

common name : eye gnats , grass flies , eye flies , fruit flies scientific name : liohippelates spp . ( insecta : diptera : chloropidae )

extremely large aggregations of eye gnats are common in areas that have loose sandy soils , especially in the southern united states . these high concentrations of flies are a great nuisance to humans and animals in rural towns as well as agricultural , recreational and tourist areas . while they do not bite , liohippelates spp . have been implicated in the transmission of several diseases to humans and livestock including human acute conjunctivitis ( pink eye ) . due to the increase of transmission of pink eye and the reduction in labor efficiency caused by extreme numbers of eye gnats in the coachella valley , california , a control project was initiated by the bureau of entomology in the 1920s to focus on the life history and possible control measures for this pest . hall ( 1932 ) subsequently implicated liohippelates pusio ( loew ) as one of the limiting factors in the development of the coachella valley .
the majority of the flies encountered in the southeastern region of the united states are liohippelates pusio and liohippelates bishoppi ( sabrosky ) , and as a result the biological information below will focus broadly on these two species .
adults : adult liohippelates are true flies ( bearing only two wings ) and are very small , approximately 1 . 5 to 2 mm long , and shiny black or grayish in color with clear wings . some species have reddish or yellowish heads . legs tend to be reddish - yellow to brown with brown bands ( hall 1932 ) .
figure 2 . lateral view of an adult liohippelates , unknown species . photograph by erika t . machtinger , university of florida .
eggs : the eggs of liohippelates flies are a pearlescent white and approximately 0 . 5 mm long . they are half as wide ( 0 . 25 mm ) as long , resembling a banana with one side curved and one nearly straight ( hall 1932 ) . eggs are deposited below the surface of loose soils .
larvae : the larvae hatch in seven to 11 days and feed on organic matter ( kahn 2008 ) . the larvae average 3 mm in length and are a whitish color ( hermes and burgess 1930 ) . larvae are pointed towards the anterior end and rounded towards the posterior . the mouth hook is darker than the rest of the body and curved gently downward .
pupae : the pupae are approximately 2 . 25 mm in length , depending on the media in which larvae developed and grew ( hall 1932 ) , and a reddish - brown color , turning darker as they age . liohippelates pupate in or around sand mixed with organic matter , such as manure , hay and remaining harvested crop debris .
figure 3 . primary liohippelates breeding sites in florida include loose soils with organic matter and moisture , as is found on many livestock facilities throughout the state . photograph by erika t . machtinger , university of florida .
liohippelates spp . are holometabolous , meaning they have four distinct life stages ; egg , larvae , pupa and adult . the life cycle of liohippelates can range from 11 days to three months depending on development conditions such as temperature and moisture ( hall 1932 ) . development from egg emergence to the adult is completed in approximately three weeks during the summer in florida ( bigham 1941 ) and multiple generations can occur each year . breeding sites are primarily those with freshly disturbed soil mixed with organic matter , such as cut grass and hay , and moisture . disturbances can be caused by digging , plowing , harrowing , or even by livestock activities ( bigham 1941 , mulla 1962 ) .
liohippelates are not host specific and will feed on the fluid from wounds , eyes , nose , and other areas on humans as well as livestock and domestic pets in a variety of situations . while they do not bite , due to their persistent feeding behavior this group of insects is responsible for extreme annoyance to people and animals when they occur in large numbers . in livestock , it has been suggested that high numbers of liohippelates can cause losses in condition , such as weight , due to continuous and unrelieved attack ( hinkle et al . 2001 ) .
figure 5 . congregation of adult liohippelates spp . around the eye of a horse . photograph by erika t . machtinger , university of florida .
many species of liohippelates have been implicated in the mechanical transmission of several diseases and conditions in humans and livestock . mechanical transmission of pathogens causing disease from liohippelates to humans or livestock occurs when a fly comes in contact with a pathogen , such as a bacterium or virus , and subsequently feeds or rests on a human or animal , transmitting the pathogen from one location to another by contact . as feeding occurs on the blood , mucus , and other fluids around natural orifices of mammals , pathogens can be carried easily into the body .
human acute conjunctivitis , also known as
pink eye
or
sore eyes ,
is caused by one or more bacteria that can be mechanically transmitted by liohippelates . pink eye causes pain , swelling , changes in vision and extreme sensitivity to light ( mideha 2010 ) . incidents of conjunctivitis have been shown to increase during liohippelates outbreaks ( dow and hines 1957 , greenberg 1973 ) . in california , hall ( 1926 ) correlated pink eye to high populations of lioppelates flavipes ( loew ) .
liohippelates flavipes and liohippelates pallipes have been shown to mechanically transmit the spirochete treponema pertenue , the causative agent of yaws , in jamaica and parts of south america ( kumm 1935 , kumm and turner 1936 , saunders et al . 1936 ) . yaws is a skin infection that causes ulceration and , in severe cases , can affect bone and cartilage . yaws occurs mainly in warm and humid regions of the world , including much of south america , and primarily affects children under the age of 15 . yaws is especially common in poor communities and those in crowded conditions ( dnz 2010 ) .
figure 6 . this person has yaws with 8 month - old juxta - articular nodules on the left elbow . photograph by peter perine , cdc .
liohippelates has been implicated in mechanical transmission of pathogens between animals as well . in cattle , liohippelates can transmit the causative agents of acute bovine mastitis ( sanders 1940 ) and vesicular stomatitis ( taplin et al . 1967 ) . acute bovine mastitis is inflammation of the mammary glands , primarily caused by bacterial infection , which can be extremely painful and compromise milk quality . mastitis may also cause death in extreme cases ( bradley 2002 ) . treatment for mastitis includes the use of antibiotics , which has possible implications in public health as resistant bacterial strains may not respond to treatment ( bradley 2002 ) and milk from treated cattle cannot be sold for human consumption until the required withholding time has elapsed .
vesicular stomatitis is a reemerging viral disease that presents as lesions on the tongue , coronary bands and other body regions of cattle as well as horses , sheep , goats and pigs ( usda 2007 ) . this disease is remarkably similar in presentation to the deadly foot - and - mouth disease , which was eradicated from the united states in 1929 ( usda 2007 ) and infection can transfer to people who handle infected animals .
figure 7 . congregation of adult liohippelates around the puncture wound of a horse . photograph by erika t . machtinger , university of florida .
currently , there is no effective area - wide control . various insecticides , fogs , and soil treatments have been tested , but due to the incredible numbers of flies produced in the soil , area - wide treatment is nearly impossible . insecticides applied on a community level for mosquito control may reduce attack , but development sites quickly repopulate as the insecticide dissipates ( kahn 2008 ) .
repellents containing diethyl toluamide ( deet ) provide temporary protection from eye gnats ( hall and gerhardt 2009 ) , and many commercial livestock insecticides that contain pyrethrins , piperonyl butoxide or other common ingredients may provide some relief to animals .

female eye gnats maintained on honey in the laboratory retained more than half their original radioactivity 5 days after being tagged with p 32 . when tagged gnats were released at the center of three concentric circles of traps on a windy day , some moved 25 feet directly upwind but an equally large number was caught 75 feet downwind in traps on the outermost circle , on both sides of the mean downwind direction . releases of tagged gnats ½ and 1 mile from a rural population center in southwestern georgia resulted in almost complete penetration of the small town on the day of release . in one test , traps more than a mile from the release box caught 15 gnats in less than 3½ hours after it was opened . chi - square analysis was used to test the hypothesis that tagged gnats are distributed like the wild ones . local departures from an overall equilibrium between tagged and untagged gnats could be recognized , and progress of the dispersal could be followed by comparing successive collections .

( townsend ) , arranged in clumped or linear distributions , oviposited randomly producing equal numbers of progeny from cither host arrangement . mixed groups of linear and clumped puparia caused changes in behavioral patterns that resulted in reduced progeny production , thus showing parasitization to be nonrandom . host destruction was , nevertheless , greater in an all - clumped distribution , tile greater acceptance of clumped groups resulting in a greater number of progeny . mixed groups involving a choice between linear or clumped distributions demonstrated the greater acceptance of clumped groups . direct observation showed that the all - dumped distribution elicited the greatest overall initial attraction for hosts and subsequent movement to other areas . it was concluded that maximum host destruction resulted when completely random behavior was involved . a recognition of this , however , required a knowledge of behavior , host condition , and progeny production . the question of evaluating an exotic parasite’s effectiveness before introduction is discussed .

trachoma is the leading cause of infectious blindness in the world . in 2008 there were 1 , 300 , 000 persons with blindness caused by trachoma and 8 million with trichiasis , which might eventually lead to blindness . in latin america it has been documented in brazil , guatemala and méxico .
to inform the presence of trachoma for the first time in colombia , amongst amerindians of the department of vaupés .
in 2003 and 2006 the amerindian makú communities of san joaquín and santa catalina , located 5 km from the border with brazil , were visited . from 2007 to 2009 , san gerardo , san gabriel and nuevo pueblo , at a 35 km distance from san joaquín were visited .
trachoma exists in colombia , and it is frequent among the studied communities . its focalized distribution makes it amenable to elimination . it is advisable to search for trachoma in other indigenous communities in vaupés with similar living conditions .

helicinidae is a family of small tropical land snails which have an operculum .

they are terrestrial operculate gastropod mollusks in the superfamily helicinoidea .

these snails are not at all closely related to the air-breathing land snails , despite a superficial similarity of the shells .

helicinidae

helicinidae are herbivorous / detritivous grazers , feeding on detritus , algal spores , moss and lichens by scraping their radula ( teeth ) along the substrate .
the mating behaviour of helicinidae is poorly known but sexes are separate and fertilisation is internal . females lay eggs in small clusters and development is direct with young hatching as juvenile snails .
for new caledonia more than 30 species of helicinidae were described up to now . the real diversity seem to amount a little more than half of this number of species , but a few taxa had not yet been described . one striking ( and frustrating ) feature of the new caledonian helicinidae is that most of them look roughly the same or very similar , at least at a first glance . this might explain to some extend the number of synonyms created in the past and the difficulties to approach this fauna .
the last comprehensive revision of the group dates back to a . j . wagner ( 1907 - 1911 ) only being followed by scattered papers on restricted areas and the systematic approaches by h . b . baker . major topics of my interest and research on the helicinidae include :

helicinidae are a tropical and subtropical family of over 500 described species . they are restricted to the caribbean and some indo - pacific and pacific islands , as well as the margins of the asian and australian continents . the family is absent from europe , africa , most of asia , new zealand , norfolk and lord howe islands and most of australia where only 7 species from a single genus (

helicinidae are found mainly in tropical rainforest on moist forest floors and the trunks of trees with some species strongly associated with limestone geologies although some species also occur in drier habitats . australian species are found mainly in tropical rainforest habitats of north - eastern australia , where some are arboreal in vine thickets and others are associated with leaf litter or limestone outcrops . helicinids often contribute a significant percentage of the diversity and abundance of the molluscan fauna in tropical forest environments .

biogeographical questions ( e . g . in the caribbean and on pacific islands )
a revision of the new caledonian species is finally published ( richling 2009 ) . it is based on very comprehensive collections made by the staff of the malacology of the muséum national d ' histoire naturelle de paris ( mainly philippe bouchet and simon tillier ) in the 70s and 80s . the project was carried out in a close cooperation with the mnhn , paris .
the lesser antilles harbour a diversity of very pretty , shiny coloured helicinids . by this colouration the species are perfectly camoulaged for an arboreal life style on and under leaves of shrubs , palms and trees . one of the most beautiful helicinids of the area is helicina rhodostoma already described by gray in 1824 . it is easy distinguished by the unusual basal spine .
besides a still wanting alpha - taxonomical revision of the lesser antillean species questions about the real generic affinities arise from the former confusion of the genera helicina and alcadia ( see also richling 2004a ) . this leads directly to the difficult biogeographical discussions in that area that still suffer from a lack of data from really thoroughly studied groups of organisms , especially among the invertebrates .

taxonomy of the gastropoda is still under revision , and more and more of the old taxonomy is being abandoned , as the results of molecular studies slowly become clearer .
these snails have an open pallial cavity which absorbs oxygen . most notably , they have only one pair of tentacles . about 130 species can be found in australia . three main groups are :
these snails , semi - slugs and slugs have two pairs of tentacles . they breathe using lungs . in australia , we have about 3000 species .
this is a group of semi - slugs and one of the most speciose families .
semi - slugs are snails that cannot retract into their shell as it is much reduced in size .
charopids or pinwheel snails are micro - snails ( from 1 . 2 - 7 . 0mm ) with an estimated 750 australian species . charopidae have their greatest diversity in eastern australia .
camaenids are generally larger than snails in most other families . in eastern australia , the stable moisture regime and acidic soils have resulted in the evolution of a number of arboreal species
caryodids are endemic to eastern australia and are generally large . they include our largest land snail , the giant panda snail .
the carnivorous snails eat meat and their diet includes a range of invertebrates including other snails . the long neck is a feature of these snails .
the snail whisperer has just finished filming a scope segment in the malacology lab at the queensland museum . the highlight of the segment is fat albert who is a giant panda snail ( hedleyella falconeri ) from mt tambourine . fat albert proved to be an upcoming movie star for the duration of the filming .
