Pine sawfly: njira kulimbana

Pine sawfly - mdani woopsa kwa mitundu yonse ya conifers. Iye amakhala mu nkhalango, pamene pali ofanana nkhuni. Zimafalikira mofulumira, wokhoza kuononga lalikulu la nkhalango. Tizilombo kuwononga kwambiri kuti mitengo.

Anapeza osati Russia (gawo European, Siberia ndi Caucasus), komanso mu Japan komanso m'mayiko ena Asian. Ngakhale inayamba zinachitika mu North America, kumene kachilomboka anakantha madera akuluakulu a mitengo coniferous. malo konse anakumana ndi tizilombo - kozizira.

ndi larva wa tizilombo chiyani?

Pali mitundu yambiri ya tizilombo awa:

• sawfly wamba;

• paini sawfly.

Ngakhale kusiyana kunja, tizilombo kuwononga kwa chomwecho, chifukwa chakuti zofanana chizolowezi. The okha kusiyana - kubalana. Wamba sawfly amapereka mibadwo osachepera awiri pa nyengo ya chilimwe, motero akhoza kuwononga kwambiri.

Kuonetsetsa zimene tizilombo Kukubweretsera masautso mtengo, muyenera kudziwa chimene chimaoneka wamba paini sawfly. Pa kukula kwa larva si lalikulu kuposa 2.5 masentimita. mtundu siyana kuchokera wotumbululuka zachikasu wobiriwira. Mutu bulauni. Pali awiri miyendo zonyenga, zomwe zinali ndi mawanga akuda.

Mphutsi za sawfly mumtundu wa ng'ombe ndi mutu. Iwo ali ndi kuwala imvi mtundu ndi khalidwe woyera lamizeremizere pamodzi mmbuyo, pa mbali ya mawanga akuda amaonedwa ndi zazikulu bulondi. Mutu ndi chonyezimira wakuda.

maonekedwe Akuluakulu

Maonekedwe a tizilombo wamkulu wa mtundu onse wa sawflies pafupifupi ofanana. Kusiyana pakati pa amuna ndi akazi.

Mkazi ali ndi kuwala chikasu, nthawi zina utoto maselo mtundu. Mozungulira kukafika kutsogolo kwa malo wakuda. Kukula ndi ang'ono, kutalika si upambana 1 centimeter.

Maonekedwe a sawfly yaikazi zofanana kwambiri ndi tizilombo pupa. Iwo lili chikhungwa wa chomwecho mtundu wachikasu, ndi kutalika si centimeter kuposa wina.

Amuna ndi wakuda, kupatula yoteroyo ndi (wofiira mthunzi). Masharubu zooneka ngati Crest ya mafunde.

Kodi ndi tizilombo?

akazi kachilomboka kuikira mazira mu njira yapadera, monga ngati kudula kudzera ndi masingano lapansi. Choncho, mazira basi kugwera mu minofu zofewa ya mtengo. Ngati inu kuyang'ana zabwino, ndiye mitengo ya paini ndi kachilombo tizilombo, mukhoza kuona lofufuma kwambiri mbali imodzi otukukira kunja (galls).

Malinga nyengo m'ma April ndipo oyambirira May mazira zitangomera mphutsi kuti anayamba kuwononga masingano wamng'ono kumbali, pamene akuluakulu kudya zonse za izo. Iwo anasunga nkhosa, kukwawa ku nthambi wina ndi mzake. Zikuoneka kuti larva munthu angathe kuwononga njira yonse mpaka masingano 40 pa mtengo wa paini.

chitukuko Larval zimatenga nthawi yaitali ndipo zikuphatikizapo magawo 6. Pa avareji akamakula m'miyezi yochepa, kenako pupate mu nthambi za mtengo, ndipo pakutha masiku 15, kuwala limapezeka paini sawfly wamba.

Koma izi sizichitika nthawi zonse. Nthawi zambiri amalondola thunthu mu bedi la udzu, Moss, masingano wagwa. Mosamala ananamizira mmenemo ndi kumira tulo tofa nato. Larva tingakhale pa boma zaka 2, ndi chakudya zina si lamulo. Anthu ena akhoza kubisala mu makungwa a mtengo pa maziko ake.

Kodi kuwononga kwambiri achita tizilombo?

Nkhalango, amene adalima conifers bwino bwino akuti "paini sawfly." Njira kuthana ndi osiyana, chinthu chachikulu - nthawi kupeza vuto, mwinamwake awononga chifukwa cha tizilombo kwambiri mumtima.

Kulikonse chifukwa kuti mphutsi ndi akulu. Ngakhale woyamba umeze masingano m'mbali, kusiya pakati pa osafikiridwa, izo wabwerera, likukhalira chikasu ndi kugwa pa nthawi. Komanso, wamkulu mbozi kudya izo zonse, ndipo ngati pali kusowa kwa chakudya, mukhoza kupeza kuti makungwa ndi zanthete. Ndipo izi akutsogolera chakuti nthambi mu korona youma. Patapita kanthawi mmera wofooka, izo limaphwanya, kudzetsa imfa mtengo.

Ngati paini sawfly anafika mitengo achinyamata paini, umafa mu zaka 4. Nthawi zambiri zimachitika kuti kuwonjezera anafotokoza ofooka mtengo tizilombo kuukira tizirombo tina. Pankhaniyi, paini afa nthawi yozizira.

Pine sawfly: bwanji kulimbana ndi kupambana m'nkhalango

The nkhalango coniferous amakhala ovuta kwambiri kulimbana ndi mtundu uwu kuopseza. Koma njira ndiyotani pakuchotsa tizilombo ali:

1. Ntchito yapadera mphete zomatira. Pa mmunsi mwa tsinde ndi wosanjikiza woonda guluu amenewa, amene si nkhani kwa kuyanika ndi kugonjetsedwa ndi chinyezi. Panthawi imene mphutsi atsika pansi kupanga chikhungwa, iwo muya- analenga.

2. Chemical kupopera mitengo wodzala ndi blizhestoyaschih.

3. Ngati malo owonongeka waukulu, chithandizo wochititsidwa ndege.

4. Kugwiritsa ntchito yokonza tizilombo ( "Virin-diprion"). pH a sing'anga tiyenela kuiganizila pamene ntchito.

Koopsa paini sawfly: kasamalidwe tizilombo m'munda

Ngati dziko mungapeze tizilombo loipali, m'pofunika kupulumutsa mitengo. Nkhondoyi adzakhala motere:

1. Kubzala pafupi ndi kachilombo paini chitsamba phwetekere. Michere umatulutsa zomera, amawateteza tizilombo.

2. Obkapyvanie kachilombo mtengo.

3. Pamaso kubzala, ndi paini achinyamata akulimbikitsidwa kudzaza mu dzenje mwapadera okonzeka phulusa njira ndi madzi.

4. Kupopera tincture wa mpiru, tomato, tchire ndi fodya.

5. Ntchito biologics.

6. Ngati yaing'ono mitengo ya paini, kusonkhanitsa mphutsi ndi dzanja. Pankhaniyi, onetsetsani kuti kuvala magulovu ndipo Goggles. Tizilombo ngati ngozi burps mwazi wake, ndipo zimenezi zingachititse munthu aakulu awo sagwirizana anachita.

njira zopewera

Ngati mtengo chimodzi mu nkhalango nakantha paini sawfly, njira ya kulimbana ayenera kumwedwa nthawi yomweyo. Koma si nthawi zonse zotsatira ankafuna. Njira iliyonse ndi zabwino ntchito pa nthawi yeniyeni (kukhwima larval, mapangidwe pupal, ndipo nthawi zina kubalana). Choncho ndi bwino kupewa pakutchulidwa tizilombo zoipa. Pakuti ichi pali miyeso wapadera njira:

• Mu njira zambiri, kufalikira kwa sawfly paini kumathandiza kuti nyengo yabwino. Ngati olosera nyengo kulosera otentha ndi youma May ndi June, ndi chikhulupiriro 80% tinganene kuti mitengo kukumana ndi tizilombo. Ngati mu miyezi awa amapita okwanira kuchuluka kwa mvula, simungathe nkhawa paini lapansi. Pa chinyezi mkulu tizilombo mphutsi akuphedwa.

• Ngati n'kotheka, ndi bwino kudzala nkhalango wosanganiza (coniferous ndi deciduous). Pamaso pa zitsamba complicates anthu wamkulu foraging.

• Pine sawfly - ndi chokoma mbamu mbalame. Kumanga birdhouses, kulisunga kuti akope mbalame, amene chilengedwe orderlies nkhalango.

Pine sawfly wachulukitsa mofulumira ndipo amagwira ambiri mitengo. Nkhondo m'pofunika kuti kupewa kutha kwa nkhalango.
