Lasia klettii: Cov duab los ntawm April Nobile, TSHEB
Rau qhov cov tshuab yoov yog tsis muaj kab mob kuv pog overly txog. Txawm li cas los, enigmatic tsev neeg Acroceridae yog lub kos. Kuv mam li pib txij ua ke mus ua ke koom ib co nthuav genera – morphology cov tsev neeg yog miv amazingly. Feem ntau ntawm cov hnub kuv yuav siv rau lub tsev khaws puav pheej inventorying peb noog txog loj heev lawm 16,000 Acorcerids (aka choj taws yoov). Uas tej zaum yuav tsis sound tag thiab impressive thaum koj piv rau lwm cov tsev neeg ntau ntau (thiab nws daj zoo thiab lub dhau 17,500,000 lwm yam nrws peb muaj nyob rau hauv cov tsev khaws puav pheej); tab sis nws puv los sawv cev ntau, Yog hais tias tsis muaj cov, ntawm tag nrho paub tias lub nrws rau tag nrho tsev neeg. Txawm tias yuav loj assemblages cov yoov rau cov hauj lwm, lub xeev California Academy of Sciences yooj yim thov tau cov ntaub ntawv ever vim tau tus sau rau Dr. Evert kuv. Schlinger (Leej puav tuaj cuag hauj lwm los ntawm cov tsev khaws puav pheej).
Acrocerids sib sau ua ib pawg theej yooj yim kawm vim tsawg npaum li cas yog nyob qhov, lawv ib parasitoid, tsis yooj yim npaum li cas lawv tsis tau txais rau tis. Lawv tus loj hauv sab qab plab no packed nrog nqaij uas rocket tus yoov ya nrog cua – li ntawd, yog hais tias koj tsis ntes nws thaum lub paj koj nyob nraum tshuav kublug ntxiab Malaise. Ev puas tau qhia rau kuv ib zaj dabneeg kev kawm rau cov nyob hauv Costa Rica tis. Koj sawv downwind ntawm tus colleague hauv lub tshav pob – Thaum ib tug neeg hnov tej yam zauv ib cheebtsam yav tas los, koj viav vias wildly hoping rau lub snare yoov… nws ua hauj lwm txhua txhua ib zaug hauv ib pliag. Cov yoov no kuj yog cov tsuas paub endoparasites laus kab laug sab. (tej zaum mas muaj ib cov ntaub ntawv ntawm ib lub Tachinid…). Cov genus hais los saum toj, NeoLasia, yog ib tug kab mob no ntawm Theraphosid tarantulas (ib yam dab tsi zoo li Aphonopelma). Ua ib tug menyuam kab yoov, txoj kev tuaj tus ceg ntawm ib kab laug sab thiab ua burrows hauv lub plab mog tuaj qhov twg nws mam li yuav ya mus nyob rau ib sab ntawm cov phau ntawv lub ntsws thiab pokes me ntsis pa zoo li tus d.. Ces nws waits ntuj ntev rau tus kab laug sab los ze maturity. Nrog poj niam tarantulas, cov yoov no yuav yog dormant xyoo lawm. Nws thiaj li akin to cov yeeb yam Aliens tej yam tshwm sim thiab tus menyuam kab yuav tus kab laug sab nyhuv ces emerges los pupate. Tiam sis koj khom lub tsheb tawm losis tsis ib kab laug sab muaj tus kab mob cab no yeej ua tsis tau ib tug dissection – loj li collections kab laug sab. nyob yuav tsum raug tswj tseg kom tau cov ntaub ntawv ntawd. Parasitoid ib txias li ntawd xwb, yog.
Tus mus saum toj no (Lasia klettii tus tshiab, unnamed, hom) yog sau rau hauv 1977 ntawm Schlinger nyob ze lub nroog Alamos, Mexico – rau paj nrog mimic tus qauv yuav, ib cov kab Chrysomelidae (kab neeg, tej tswv yim tshaj tsev neeg?).
Interesting heev! Tsis xav, vim koj pav collections loj loj nyob nrog cov kab laug sab., muaj kev soj ntsuam mus txog rau lub hobby tarantula keepers nyob hauv ib tug hu ua rau nrws? Thaum kuv muaj yeej tsis pom ib yam spectacular kom raws li cov saum no mam li tawm hauv ib tug tsiaj qus caught tarantula, Kuv twb tau hnov ntawm ib txhia neeg uas twb tau tuaj nrog “coj txawv txawv” yoov yav tag los…
Caw lawv rau cov tarantulas muaj hmoov txhuas los kuj ob peb nrws rau Brent Hendrixson rau nws kho nqi lus hauv lub genus Aphonopelma, tsawg rau lub tebchaw Asmesliskas haiv hom. Kuj ntau heev ntawm ntau hom tuaj ntawm Central thiab mis kas qab teb imports, Nws yog ib qho tsis muaj xyaum kuv nyiam los yog yuav tsis kam…tiam sis nws yuav ua rau kom tsawg kawg yog ob peb muab cov zauv feem nrws. Tus xav xwb.
Kuv xav tias cov lus teb no somewhat. Kuv twb mus txog ntawm lus cam thiab tej zaum tseem nyuam qhuav muab ib tug tham me ntsis rau SF Bay Area Tarantula Society. Qhov teeb meem los rau haiv neeg teb tam sim ntawd thaum lawv pom ib tug giant grub nkag hauv cov kab laug sab – lawv mus txog hauv lob lawv nqi zog mus thiab nyob rau hauv cov txheej txheem ua puas tus menyuam kab los ntawm yoov qho pupae. Thaum nws puv cov yoov no muaj zoo nkauj ua ntej pupating thiab thaum kuv pom ntau dluab kas, yeej tsis pom ib tug yoov reared ua ib hobbyist. Kuv xav tias cov tej yam nyuab biggest yog tias neeg tsuas pom lawv muaj li cas tom qab lawv tau ib kab laug sab tuag – thiab yuav muaj nws ces yuav tau xyoo ua ntej lwm tus uas lawv qus ntes tau kab laug sab. tsis paub qab hau yog parasitized!
Uas ua rau txoj kev txiav txim zoo heev, Kuv twv nws tsis tshua tshwm rau kuv ntawd rau ntau tus neeg muaj tus cab no mam li tawm hauv ib qhov ntawm cov captives yog tus phem tshaj plaws…tsi tshaj ntawd yuav ua rau kuv lub hnub. 🙂
Yog tias cov kab laug sab nqi koj them nyiaj ob peb puas!!
Kuv xav tias cov miv uas yoov ib tug pom zoo heev. 🙂
Thawj tswv yim ntawm cov kab yog ib hom Chrysolina (subfamily Chrysomelinae), tiam sis kuv paub cov Neotropical chrysos no xwb.
Tsaug rau lub genus ballpark – Kuv yuav tau khawb av ntawm peb collections ntawm no yog kuv tsis tau nqaim nws mus ntxiv saib.
Koj puas txhais tias cov acrocerid yoov yog tus tsuas paub dipteran endoparasites kab laug sab. laus? Muaj cuab kav kab laug sab-tua nematodes, thiab cov mantidfly yuav nkag mus rau hauv lub ntsws phau ntawm lawv ib hom tsiaj kab laug sab thiab noj hemolymph thaum hitching caij lub qe deposition site.

Ntawm no yog ib qho txias txog ib mantidfly vaim rau ib kab laug sab, fwm hauv amber!

(Ntsoov, tias yus lub rau sab nraum cov kab laug sab, tiam sis tus ncej muaj xav pab ntxiv yog nyob lwm tactics.)
Ua tsaug rau taw uas! Koj nyob nraum tseeb kiag, Thaum twg kuv twb xav “tsis endoparasitoids” Kuv lig neglected cov kab tsuag xws li cov nematodes. Kuv yuav tsum tau rov lo ua cas nws yuav ua tau mus nematode dua ib zaug nyob rau hauv lub khob cij captive kab laug sab.!
Kuv kuj tsis paub tias txog mantidflies. Yeej yuav tsum nuv rau hauv cov ntawv nyeem, tej zaum yuav muaj lwm diptera los yog hymenoptera parasitoids li nyuam qhuav paub tias. Txias heev, tsaug rau qhov txuas.
Augh augh augh thiab os tus duab ib huuuuuge nematode los ntawm ib tug kab laug sab! Yog tej zaum tseem yog ib tus cwj pwm modifying cab no — nws induces cov tswv tsev los nrhiav kev ua dej ua ntej yuav tuag, yog li tus nematode sau nws lub neej nws. (Zoo li tus cua nab horsehair nyob crickets!)
