ixodes neuquenensis is a species of tick that lives on the monito del monte ( dromiciops gliroides ) , a nocturnal marsupial that lives in the northern temperate forests of southern south america .

due to the near-threatened status of its host , ixodes neuquenensis is also at risk .

in summary , this study provides solid evidence for extending the range of lb borreliae to the western coast of south america . it also serves as a basis for further studies of relationships of b . chilensis with ixodes ticks and rodents , and the pathogenic relevance of this genospecies .
almost two years ago , we launched pubmed journals , an ncbi labs project . pubmed journals helped people follow the latest biomedical literature by making it easier to find and follow journals , browse new articles , and included a journal news feed to track new arrivals news links , trending articles and important article updates .
pubmed journals was a successful experiment . since september 2016 , nearly 20 , 000 people followed 10 , 453 distinct journals . each customer followed 3 journals on average .
though pubmed journals will no longer exist as a separate entity , we hope to add its features into future ncbi products . we appreciate your feedback over the years that made pubmed journals a productive test of new ideas .
ncbi labs is ncbi’s product incubator for delivering new features and capabilities to ncbi end users .

the united nations declared 2010 the international year of biodiversity . in celebration of the enormous diversity of parasites and to highlight their importance , we created this blog , which showcased a species of parasite every day . now that 2010 is over , we will continue to add more parasites from time to time , and write about any newly published research on parasite species that we have posted about yet .
see this post from the start of 2011 where we discuss the sheer scale of parasite biodiversity , and this post from the end of 2011 pretty much summarizes the mission of this blog .
got parasites ? the american society of parasitologists is interested . we invite you to share with us your observations , ideas and questions about parasites . our members and the journal of parasitology represent a wide range of research interests including ecology , evolution , systematics , immunology , biochemistry and molecular biology . please post any aspect of parasitology you wish to share with us on our facebook group page . please go to our home page at

in an effort to explore the question of whether b . burgdorferi s . l . is present in south america , i . stilesi ticks collected from vegetation and colilargos in a forest reserve in southern chile and from captive pudus undergoing rehabilitation in the same region were examined . these ticks harbored a novel lb group borrelial species genetically distinct from other lb borreliae from north america , europe and asia . we propose this new borrelial genospecies be named borrelia chilensis va1 in honor of its country of origin .
sp . using serial dilution on solid medium and liquid media , ultrafiltration ( 0 . 2 μm and 0 . 45 μm pore sizes ) , flow cytometry , and antimicrobials ( kanamycin , erythromycin , tetracycline , gentamycin , novobiocin , vancomycin , bacitracin , cycloserine , rifampicin , phosphomycin , amphotericin b ) were unsuccessful .
subcultured at weekly intervals in bsk - h media ; early passages were stored at −80°c . cultured spirochetes frequently grew in long filamentous forms (
morphology of spirochetes from i . stilesi midgut ( a ) , or after in vitro culture for ( b ) 5 or ( c ) 12 days or after ( d ) 9 passages in bsk - h media ( magnification , 100× ) .
borrelial dna in ticks and comparison with dna from b . chilensis va1 cultured from a tick
standard and nested / seminested pcr amplification was used to detect borrelial dna in ticks obtained from the environment and from pudus and colilargos . tick 16s rdna was used as an internal control to define the quality of isolated dna . borrelial 16s rdna ( 800 bp ) was amplified from one flat male tick collected from vegetation in 2005 , two flat female ticks collected from vegetation in 2008 and two flat nymphs removed from colilargos in 2011 , including the one in which spirochetes were observed (
) . the mean prevalence of infection in ticks ( 10 % ) was not significantly different between ticks collected from environmental vegetation in 2005 - 2008 and from colilargos in 2011 ( p > 0 . 05 , fisher’s exact test ) . none of the ticks removed from pudus contained borrelial dna .
b . chilensis va1 sequences in i . stilesi ticks and in b . chilensis va1 cultured from i . stilesi
a 2005 : 13 ticks from environmental vegetation , fixed in 70 % ethanol at 4°c : 1 positive for b . chilensis va1 ( 7 . 7 % prevalence ) .
b 2008 : 25 ticks from environmental vegetation , fixed in 70 % ethanol at 4°c : 2 positive for b . chilensis va1 ( 8 . 0 % prevalence ) .
c 2011 : 12 live ticks from four long - tailed pygmy rice rats ( colilargos ) ( oligoryzomys longicaudatus ) , 2 ticks positive for b . chilensis va1 ( 17 % prevalence ) . difference in prevalence of infection between ticks obtained from environmental vegetation and ticks removed from rice rats is not significant ( p > 0 . 5 , fisher’s exact test ) .
d b . chilensis ( bch ) va1 cultured from tick 5 ( fourth passage ) . sequences for clpa , clpx , nifs , pepx , pyrg , recg , rplb and uvra were identical to those obtained directly from tick 5 .
) , indicating that they represented new alleles for each of these genes ( data not shown ) .
sequences amplified from uruguayan ticks . additional phylogenetic analyses of 23s rrna and igs sequences from several ticks confirmed that borrelial sequences amplified from chilean ticks belonged to a single well - supported clade with 98 % and 99 % support , respectively ( data not shown ) .
va1 was closely related to lb borrelia and only distantly related to rf borrelia . pairwise genetic distances of the concatenated housekeeping genes of
va1 from rf borrelia were 0 . 2859 - 0 . 3011 , while pairwise genetic differences from other lb borreliae were 0 . 0952 - 0 . 1138 (
) . all these distances are much larger than the species threshold of 0 . 0170 using this typing scheme (
va1 was characterized using pcr and pulsed - field gel electrophoresis ( pfge ) on borrelial samples taken from the upper third of culture tubes . microscopic examination of two replicate preparations showed they contained < 1 and 4 contaminating
sp . cells per 100 spirochetes . pcr and pfge results were similar with both preparations . lp17 was not present in
b31a3 by pcr and corresponded to the smallest band in pfge . of the larger borrelial plasmids , lp54 and lp56 were identified by pcr in
) probably corresponding to the four mid - range bands seen on pfge . this profile was clearly different from the mid - range profile of
plasmid profiles of b . burgdorferi b31a3 and b . chilensis va1 analyzed by ( a ) pcr using primers designed for b . burgdorferi b31 and ( b ) pfge of whole - cell dna prepared in agarose plugs . see experimental procedures for details .
ticks collected from local vegetation and from a rodent endemic to chile and argentina . dna sequencing analysis of pcr amplicons from 16s and 23s rrna genes , igs ,
s . l . complex . sequences for each gene from individual ticks ( when multiple sequences were available ) formed well - supported single clades within the lb borrelial group . furthermore , amplicons for igs ,
s . l . complex . taken in toto , these observations provide strong evidence for these sequences representing a new borrelial species and the cultured organism validly representing the borrelial dna found in ticks . we propose to name this new species
, and note that this extends the range of lb group borrelia in south america and the southern hemisphere .
) . the reason for this is not clear . it might be the result of low spirochete load given that microscopy of tick gut fluid showed 0 - 1 spirochetes per field . low spirochete load may be a general condition of southern hemisphere borrelia as recently demonstrated by the inability of barbieri et al . to amplify full sequences of a new borrelial species in ticks from uruguay (
) . other causes for this lack of amplification could be dna degradation as a result of the prolonged fixation of ticks in ethanol , the presence of pcr inhibitors in the dna extracted from the ticks , sequence heterogeneity at the priming sites or some combination of these factors . for example ,
) . the different branching orders in these trees do not reflect phylogenetic uncertainty or the evolutionary history of the species but rather reflect the evolutionary history of the particularl loci used to generate the trees . the basal position of
sp . after repeated attempts by different methods , we took advantage of the physical separation of spirochetes and gram - negative betaproteobacteria during culture to effect a partial separation of the two bacteria . pcr and pfge showed this new
b31a3 while lacking others present in this strain . some of these latter negative results may not indicate absence of particular plasmids but may be a result of sequence heterogeneity at the priming sites .
; król j . e . , rogers , l . m . , sen , d . , and top , e . m . , genbank accession
, no attendent publication ) , but the plasmid content of delftia sp . is in general poorly characterized (
by pcr , but its presence in pfge analysis could not be definitively determined because of the multiplicity of mid - range sized plasmids visible on the gel . obtaining a pure culture of this bacterium will be essential to determine its pathogenic potential . in this regard , our inability to grow
sp . may suggest a symbiotic relationship between these two bacteria and frustrate such studies .
ticks for this study were collected in the san martin experimental forest preserve ( 39°38′ s , 73°07′ w ) , universidad austral de chile , valdivia , chile and from captive pudu deer undergoing rehabilitation at the wildlife rescue center in the veterinary hospital at the faculty of veterinary sciences , universidad austral de chile , valdivia . the preserve is located in the valdivian temperate rain forest ecoregion in the eastern foothills of the pacific coastal range in region de los rios ( region xiv ) at an average elevation of 3 m above sea level . its climate is temperate and wet ( average temperature , 12 . 1°c , range 0° to 30°c ; average annual rainfall , 2 , 500 mm ) ( miller , 1976 ; veblen and schlegel , 1982 ) .
ticks were collected in 2002 , 2003 , 2005 , 2008 and 2011 . a group of 38 ticks was collected from the environment during the austral springs of 2005 and 2008 by dragging 1 m
) undergoing rehabilitation at the wildlife rescue center in the veterinary hospital , faculty of veterinary sciences , universidad austral de chile , valdivia ( one in 2002 , one in 2003 , and at least one in 2005 ) . all ticks clinging to the drag cloth or attached to the deer were removed with forceps , fixed with 70 % ethanol and stored in vials at 4°c for later identification and dna extraction . a third group of 12 ticks was removed with forceps from four colilargos (
) trapped in the reserve in september , 2011 . these ticks were stored alive in sterile glass vials at ambient temperature for later identification , borrelial culture , and dna extraction . fixed and living ticks were identified by standard tick keys (

zelus luridus , also known as the pale green assassin bug , is a species of assassin bug native to north america .

it is the most common zelus species in the eastern united states .

the size ranges from twelve and a half to eighteen millimeters long .

on average , adult females are sixteen millimeters long , while males are fourteen millimeters long .

though the base color is pale green , markings on the back can range from dark brown or red to bright yellow .

nymphs are generally more solid green , wingless , and with narrower bodies than adults .

the most reliable feature to distinguish this species from others is the pair of spines on the rear corners of the pronotum .

these spines are long on the lighter colored individuals and shorter on ones that are darker .

it can also be distinguished by dark bands on the distal ends of the femurs , but these can often be too light to be easily seen .

the egg masses , which are laid from late june to august , are conical in shape with a flat top .

they are laid on leaves in groups of twenty to fifty and held together with a sticky , brownish material .

like many other assassin bugs , zelus luridus preys on other insects .

it will often wait on leaves to ambush passing insects , but occasionally it also actively hunts .

for this , it uses sticky traps , a common predation strategy to species within the genus zelus .

the sticky material is produced by a gland on the leg .

this gland develops in the second instar .

during the first instar , the nymphs use secretions deposited over the egg batch by the female as the source of their sticky material .

zelus luridus

this is an assassin bug in the genus zelus . moving to that guide page . update : z . luridus is the species .
i found a zelus renardii nymph crawling on my bed on the second story . is there a chance that it emerged from eggs laid in my house ? also , what do zelus renardii nymphs eat ?
there are at least two generations annually here along the front range in colorado , probably three or more generations in southerly latitudes . i notice nymphs of z . luridus in spring , so it is likely that winter is passed in the egg stage .
there are currently five recognized species of zelus north of mexico , most with wide geographic distributions . few are readily identifiable to species just by looking at them , but common ones include : the lovely green zelus luridus with a sharp spine on either side of its thorax ; the bright red and black milkweed assassin bug , z . longipes found in the southeast u . s . ; and the non - descript z . tetracanthus with its four small
knobs
across the top of its thorax . the leafhopper assassin bug , z . renardii , is common in the southwest u . s . and has been entertained as a potential biocontrol agent for pest reduction in agricultural settings .
genus zelus fabricius in the united states , canada , and northern mexico ( hemiptera : reduviidae ) hart e . r . 1986 . ann . ent . soc . am . 79 : 535 - 548 .
assassin bugs in general are indiscriminate predators of other insects , and zelus is no exception . so , while they will dine on leafhoppers , small caterpillars , and other pests , they will also capture beneficial insects such as small bees .
zelus species range from 14 - 21 millimeters in body length as adults , and are relatively easy to recognize with their slender build , long legs and antennae , and diurnal period of activity . they are largely arboreal , so you will find them mostly on foliage and flowers of trees , shrubs , and herbs .
this is a zelus luridus - or pale green assassin bug . i believe this is an immature one . being
true bugs
, the babies of these insects look like small versions of the adults - without wings . most insects go through different stages - egg , nymph , pupa , before appearing as an adult that most of us recognize . true bugs grow into adulthood without going through these changes . in addition they eat the same food as the adults ( unlike insects like butterflies , whose babies ( ( caterpillars ) ) eat leaves ) . here is an explanation of these processes : urltoken and here is information about the little bugger who bit your child : urltoken i hope this is helpful . please contact aae again if you have further questions .
your garden is full of amazing predators , easily overlooked among the foliage and flowers . no matter where you live in the u . s . and southern canada , save perhaps for the northern rocky mountains , you probably have sundew assassin bugs of the genus zelus lurking in the yard . these leggy insects move slowly about , or wait in ambush for potential prey .
eric , any idea how long it takes for zelus eggs to hatch ? i collected and kept a female z . renardii in a small jar for a few days and then let it go . while in the jar , she laid eggs that i did not notice . after what seemed like just a few days i noticed the nymphs crawling all over in the jar .

this is a dead bug , since my wife put it in the sun . when it was alive , it was mostly green with a sort of long chevron shaped mark ( with the apex toward the head ) on it ' s back ( wings ) . it ' s about 5 / 8
long not including the front legs . i found it in the kitchen when it landed on my wife in the evening . she said she found another one in her car a day or two later . it ' s possible that we picked them up while camping at summersville lake , w . va . a week earlier . i was trying to be nice to the bug . instead of killing it , i began to carry it outside between my fingers . the little b _ _ _ _ _ _ bit or stung me on the tip of my ring finger . i ' m not sure it ' s related , but i ' ve had an aching feeling in that arm since about a day afterward .
before it dried out , did it look something like this ? urltoken - - t . carter ross
nope . it was mostly green , didn ' t have all that red . i ' ve found there are at least 3 , 000 species of assassin bug .
they have piercing sucking mouthparts so its more of a stab than a bite . when i was a kid i made the same mistake with a wheel bug that patrick mentioned and it seemed much worse than any bee or wasp sting .
thanks for the comment . i too thought it seemed to have a sucking mouth apparatus similar to that of a fly .
this is an assassin bug , family reduvidae . they do bite in self defense , as well as being predatory on other insects , and some of them can inflict a fairly painful stab . the wheel bug , a large gray species , is infamous for inflicting painful wounds . i have a trick for removing insects and spiders from my house without killing them : i coax them into a large plastic cup laid on its side , say , with a wisk broom or a piece of paper . i then carry them outside in the cup . most things cannot climb the walls of the cup , so i know i won ' t get bitten or stung . again , assassin bugs are just about the only
true bugs
that do bite . patrick coin durham , north carolina
thanks for the name and comment . i ' ve used a similar method , putting a cup or glass over the bug and then sliding paper between the cup and the surface , for wasps and hornets , but this guy appeared so harmless . i won ' t assume that again !

sundew assassins get their common name from the unique physiology that allows them to catch prey . while ambush bugs have extremely muscular front legs that snap shut on prey with stunning force , sundew assassins look like the 90 - pound weakling by comparison . their appendages are thin and seemingly delicate or flimsy . the tibiae (
shins
) of the front legs ( and to some degree the middle legs ) are densely covered in short hairs , and this is part of their secret weapon .
special glands in the exoskeleton of the legs secrete a glue - like material that that the insect intentionally smears over those hairs . this creates a sticky layer that small prey cannot escape from once the assassin grabs them . the prey - catching scenario is analogous to the insect - eating plant known as the sundew , which inspires the name
sundew assassin bugs .
when they hatch from the egg , nymphs do not have the ability to produce the glue they need . no matter , mom has covered the egg cluster in sticky goo to help repel egg parasites like tiny wasps , and the nymphs simply wipe their
arms
along the base of the egg mass to gather some glue ( weirauch , 2006 ) .
nymphs go through five instars ( an instar is the interval between molts ) on their way to adulthood . they are noticeably larger after each molt , with wing pads evident in the last couple of stages .
the egg mass reminds me of a tiny crème brûlée , but perhaps i need to eat lunch and return to finish this post later . . . . i was delighted to stumble upon a couple of egg masses in the act of hatching at the cheyenne mountain zoo here in colorado springs back on july 21 . it seems remarkable that such long - legged creatures could be packaged in such small vessels .
despite our tendency to classify insects as
good
or
bad
for our own selfish reasons , sundew assassin bugs should be welcomed for the benefits they provide in occasional pest control , and their unique behavior and
personality ,
if i dare use that word for an invertebrate .

surface morphology of legs in the assassin bug
you ' re welcome , ron ! yes , assassin bugs in general can give a painful bite in self - defense . the worst bite i ' ve ever experienced was from another kind of reduviid .
i do not know the answer to that . i suspect it varies a bit , from species to species and region to region , but i imagine it takes a week or two for the eggs to hatch .
just saw what i thought are my first samples of this species after more than 20 years in this area but saw two on the same day . funny how that works .
not likely that eggs were laid indoors . could have fallen off a tree , been blown in . . . . nymphs feed on any insect they can overpower .
that is a medical question and i am unqualified to answer it . seek a physician if you experience symptoms out of proportion to the bite ( beyond normal localized pain , inflammation ) .
is this ok to have as a pet my son caught one and we thought it was a baby mantis . it just shed and we have been giving it ants to eat or should we just let it go ?
yes , it is fine to keep as a pet , but don ' t feed it ants , especially after it has just molted . ants can kill it ! feed it aphids , leafhoppers , and other small insects that cannot bite or otherwise defend themselves easily .
i found one in my kitchen , i think , but it doesn ' t have any wings . it looks like the pictures though . is it possible that it is one ?
quite possible indeed . nymphs , which are probably already evident in southern latitudes by now , do not have wings .
tell us about it and you ' ll be helping the big bug hunt citizen science project .

is a large cosmopolitan family of about 7000 species of predatory insects in the suborder heteroptera . it includes assassin bugs ( genera :
adult assassin bugs range from 4 - 40 mm , with an elongated head and distinct narrowed neck , long legs , and a prominent , segmented tube for feeding ( rostrum ) . the most distinctive feature of the family is that the tip of the rostrum fits into a groove in the prosternum , where it is rasped against ridges there (
) to produce sound , a tactic often used to intimidate predators , rivals and attract mates .
assassin bugs use their rostrum to inject a lethal saliva that liquefies the insides of the prey , which are then sucked out by means of a cybarial pump through another passage in the rostrum . the legs of some species are covered in tiny hairs that help them hold onto their prey while they feed . as nymphs , some species will cover and camouflage themselves with plant debris , or the remains of dead prey insects [ 1 ] . some species have been known to feed on cockroaches or bedbugs ( in the case of the masked hunter ) and are regarded in many locations as beneficial . some people breed them as pets and for insect control . some assassin bug groups specialize on certain prey groups , such as ants ( feather - legged bugs - holoptilinae ) , termites , or diplopods ( ectrichodiinae ) .
that causes chagas disease , also referred to as american trypanosomiasis . triatomines are primarily nocturnal and feed on the blood of mammals ( including humans ) , birds , and reptiles .
chagas disease is named after the brazilian physician carlos chagas , who discovered the disease in 1909 . it is transmitted to animals and people by insect vectors that are found only in the americas . in the united states , chagas disease is considered a neglected infection of poverty ( nip ) , since it is found mostly in those with limited resources and limited access to medical care .
infection is most commonly acquired through contact with the feces of an infected triatomine bug , but can also be passed from mother to baby , by contaminated blood products , organ transplants , or , rarely , through contaminated food or drink . [ 2 ]
triatomine bugs are currently found over the lower 2 / 3rds of the u . s . , including hawaii . their range is expanding rapidly due to climate change , and they can live indoors and in a variety of outdoor venues : in chicken coops , dog houses , in rodent nest or animal burrows ; in rock or wood piles , beneath the bark of trees , or under concrete walkways and patios .
because most indoor structures in the united states are built with insect - resistent sealed entryways , triatomine bugs rarely infest indoor areas of houses . however , in areas of latin america where human chagas disease is an important public health problem , the bugs nest in cracks and holes of substandard housing , i . e . those with thatched roofs or mud walls .
discovery of immature stages of the bug ( wingless , smaller nymphs ) indoors may be an indication of infestation ; they are likely to be in one of the following settings : in pet bedding , areas of rodent infestation , and in bedrooms , especially under or near mattresses or night stands . in fact , the larvae of the assassin bug
transmission of chagas disease from a bug to a human is not easy . the parasite that causes the disease is in the bug feces . the bug generally defecates on or near a person while it is feeding on his or her blood , generally when the person is sleeping . transmission occurs when fecal material gets rubbed into the bite wound or into a mucous membrane ( for example , the eye or mouth ) , and the parasite enters the body [ 2 ] .
romaña ' s sign : swelling of the eyelid is a marker of acute chagas disease . the swelling is due to bug feces being accidentally rubbed into the eye , or because the bite wound was on the same side of the child ' s face as the swelling . [ 3 ] image : cdc
it is important to note that not all triatomine bugs are infected with the parasite that causes chagas disease . the likelihood of getting chagas disease from a triatomine bug in the united states is low , even if the bug is infected [ 2 ] .

structure of larvae
order hemiptera : true bugs number almost 5 , 000 species in north america , and 40 , 000 worldwide . they have mouthparts formed into a beak , adapted for sucking plant juices or the liquefied insides of their animal prey . suborder auchenorrhyncha - cicadas & planthoppers suborder sternorrhyncha - aphids , scales , mealybugs , jumping plant lice .
my little girl was bit or stung by a tiny green bug , a little bigger than a mosquito , lime green in color . the bit was painful and it swelled up but has since gone down . no one seems to know what this bug is . can you take a look at this photo and let me know please .
wow , thank you so much for your fast reply and yes it ' s name sure does match it ' s bite . my daughter is 11 and it brought her to tears , she said it was worse than a bee sting . should i be on the look out for more of these critters ? this happened while she was just sitting in the living room . again , thank you for getting back to me to quickly . diette
it ' s getting late in the year , so hopefully these bugs will soon cease to be a problem . in spite of the unhappy experience you ' ve had , these insects are beneficial in our gardens and fields . they consume lots of harmful insects . they are rather uncommon and it ' s possible that you and your daughter will live out the rest of your lives without ever encountering another one . here is a quote from a university of missouri article about assassin bugs :
avoiding our harmful assassins involves taking simple precautions . exclude them from your home by repairing window screens , applying weatherstripping , and sealing other openings . use yellow bulbs in porchlights , and dispense with bug zappers . do not camp or sleep inside caves , barns or other sheltered areas frequented by masked hunters , corsairs , and conenoses . to avoid a self - defense bite , gently brush away any bug that lands on you .
the beneficial qualities of assassin bugs far outweigh their negative potential , and learning to get along with these indispensable predators is in our own best interest .
good morning , i ' m pretty sure i just discovered an adult assassin bug in my house . i have to admit , freaks me out a bit ! how many are in here ? ? ? i ' ve attached a few photos , sorry . . . he ' s a bit smushed ! if it ' s not the assassan bug , what is this ? i was looking at the article you sent me back in october and it seems like it ' s the same bug , just an adult this time . please advise , diette
the critter in the photo is too mangled , and the resolution isn ' t good enough for me to pick out identifying details but if you google assassin bug and look at
images
you should be able to verify its identity . since these bugs produce only one generation per year - and they tend to be solitary and somewhat nomadic - there probably aren ' t lots of others in your house . they are coming in from the outside . controlling them indoors involves thorough cleaning and vacuuming to reduce other prey insects , caulking areas that may be open to the outdoor , keeping pets indoors . here is another publication that contains information about keeping them out of your house : urltoken
did not know if you can tell me what kind of insect this is and if it is bad . . . .
