Ibhayoloji kanye Nemvelo Yezinambuzane Zezitshalo
Izinambuzane zezitshalo ziyisici esiyinhloko esivimbela ukukhiqizwa kwezolimo. Ukuba khona kwazo kunganciphisa isivuno, kuphazamise ikhwalithi yezitshalo, futhi kwandise izindleko zokulawula. Kodwa-ke, ukuze kuphathwe izinambuzane ngempumelelo, ukuqonda okungaphezu nje "kokubulala" izinambuzane kubalulekile. Indlela efaneleke kakhulu ukuqonda i-biology yezinambuzane kanye ne-ecology: ukuthi izinambuzane zisinda kanjani, zizalane kanjani, zivumelane kanjani, zisakazeke kanjani, futhi zisebenzisane kanjani nezitshalo ezisingethe, izitha zemvelo, kanye nemvelo. Ngalokhu kuqonda, amasu okulawula angaklanywa ukuze asebenze kahle, abe nobungane nemvelo, futhi aqhubeke nokusimama.
Ukuqonda izinambuzane zezitshalo nezinhlobo zazo
Izinambuzane zezitshalo yizinto eziphilayo ezibangela umonakalo ezitshalweni ezitshaliwe, okuholela ekulahlekelweni kwezomnotho. Igama elithi "izinambuzane" livame ukubhekisela ezinambuzaneni, kodwa lingafaka kabanzi izimbuzane, ama-nematode, ama-mollusk (iminenke), izinyoni, kanye nezilwane ezincelisayo ezithile. Ngokomongo wezolimo zanamuhla, amaqembu avelele kakhulu yizinambuzane (isb., izintethe zamaqabunga, izimpethu zezempi, izibungu zesiqu), kanye nezimbuzane nama-nematode, okunzima ukuzibona kodwa ezinomthelela omkhulu.
Ngokusekelwe endleleni ezilimaza ngayo izitshalo, izinambuzane zingahlukaniswa zibe izinhlobo eziningana: izinambuzane ezihlafunwayo (isib., izibungu ezidla amaqabunga), izinambuzane ezimuncayo (isib., ama-aphid amunca uketshezi lwezitshalo), izimbobo (ezilimaza izicubu zangaphakathi zeziqu noma izithelo), kanye nezinambuzane ezilimaza izimpande noma izingxenye ezingaphansi komhlaba (isib., ama-nematode e-root knot). Lo mehluko ubalulekile ngoba uhlobene ngqo nezimpawu zokuhlasela, isikhathi sokuhlasela, kanye nezindlela zokulawula ezifanele.
Ibhayoloji yezinambuzane: imijikelezo yokuphila namasu okusinda
Ibhayoloji yezinambuzane zezitshalo ihlanganisa umjikelezo wazo wokuphila, ukuzala, ukuziphatha kokudla, kanye nokuzivumelanisa nezimo. Izinambuzane eziningi ziyashintshashintsha. Ekuguqukeni okuphelele (holometabolous), izigaba zokuphila zihlanganisa iqanda, i-larva, i-pupa, kanye ne-adult, njengakwizibungu kanye nezinhlobo ezithile zezimpukane. Ekuguqukeni okungaphelele (hemimetabolous), izigaba zokuphila ziyiqanda, i-nymph, kanye ne-adult, njengakwizintethe zezitshalo kanye nezintethe. Isigaba ngasinye sivame ukuba nemikhuba yokudla ehlukile, izindawo zokuhlala, kanye nokuthambekela kokulawula. Isibonelo, izibungu zivame ukuba yisigaba esilimaza kakhulu ngenxa yezidingo zazo eziphezulu zezakhamzimba zokukhula.
Ukuzalana kwezinambuzane nakho kunquma isivinini sokuqhuma kwenani labantu. Izinambuzane eziningi zinezinga eliphezulu lokuzala, isikhathi esifushane sokuphila, kanye nekhono lokubeka amaqanda amaningi. Ama-aphid angazala ngisho nangokwengxenye yezakhi zofuzo ngaphansi kwezimo ezithile, okuvumela inani lawo ukuba lande ngokushesha ngaphandle kwesidingo sokuzalana. Ngakolunye uhlangothi, ezinye izinambuzane zibonisa i-diapause, isimo "sokulala" ngezikhathi ezithile ukuze zisinde ezimweni zemvelo ezingezinhle, njengesomiso noma amazinga okushisa aphezulu. I-Diapause ivumela izinambuzane ukuthi ziphinde zivele lapho izimo zithuthuka futhi ngokuvamile iyimbangela yokutheleleka okuphindaphindiwe unyaka nonyaka.
Ngaphezu kwalokho, ukuzivumelanisa nezimo nezinambuzane kanye nokuziphendukela kwemvelo kuletha izinselele ezinkulu. Ukusetshenziswa kwezibulala-zinambuzane okungahlakaniphile kungakhuthaza ukukhethwa kwezinhlobo ezimelana nezinambuzane, okuholela ekuthuthukisweni kokumelana nezinambuzane ngokuhamba kwesikhathi. Ukuzivumelanisa nezimo kwenzeka nangokushintsha kokuziphatha, njengokuthi izinambuzane zisebenza kakhulu ngezikhathi ezithile ukuze zigweme ukuchayeka noma ukuthuthela ezindaweni zezitshalo ezivikelwe kakhulu.
I-ecology yezinambuzane: ukusebenzisana nemvelo kanye nezinhlelo zezolimo
I-ecology ifunda ubudlelwano phakathi kwezinambuzane nemvelo yezinto eziphilayo (ezinye izinto eziphilayo) kanye nemvelo engenazo izinto eziphilayo (izinga lokushisa, umswakama, ukukhanya, umoya, njll.). Izinhlobo zezinambuzane azikaze zibe khona zodwa; zibunjwa ukutholakala kokudla (izitshalo ezihlala kuzo), ingcindezi evela ezitheni zemvelo, kanye nezimo zezulu kanye nokuphathwa kwezitshalo.
Isimo sezulu sidlala indima ebalulekile. Izinga lokushisa lithonya izinga lokukhula kwezinambuzane: emazingeni okushisa afanele, amaqanda achanyuselwa ngokushesha, izibungu zikhula ngokushesha, futhi izizukulwane ziyanda ngesikhathi esisodwa sokukhula. Umswakama uthinta ukusinda kwamaqanda, ukuthuthukiswa kwezinambuzane ezibangela izifo (njengesikhunta esibangela izifo), kanye nomsebenzi wezinambuzane ezithile. Imvula enkulu inganciphisa inani lezinambuzane ezincane ngokususa izitshalo ezithile, kodwa futhi ingadala izimo ezikhuthaza ukuvela kwezifo zezitshalo ezenza izitshalo zibe buthaka futhi zizenze zibe sengozini enkulu yokuhlaselwa yizinambuzane zesibili.
Isakhiwo se-agroecosystem naso sibalulekile. Ukutshala izitshalo eziningi ngesitshalo esisodwa kanye nohlobo olulodwa kuvame ukuhlinzeka ngemithombo yokudla eningi nefanayo yezinambuzane, okwandisa amathuba okuqhuma kwabantu. Ngokuphambene nalokho, amaphethini ahlukahlukene okutshala, ukutshala okuxubile, noma ukuba khona kwezindawo zokubalekela kungandisa ukuba khona kwezitha zemvelo futhi kunciphise ukubusa kwezinambuzane ezithile. Izindawo eziphilayo ezihlukahlukene zivame ukuba nebhalansi ezinzile ngenxa yezindawo zokudla eziyinkimbinkimbi.
Ubudlelwano phakathi kwezinambuzane, izitshalo ezisingethe kanye nezitha zemvelo
Emvelweni yezinambuzane, izitshalo ezihlala kuzo azizona nje "izisulu ezingenzi lutho." Izitshalo zinezindlela zokuzivikela ngokomzimba namakhemikhali. Ukuzivikela ngokomzimba kungafaka phakathi ama-cuticle aminyene, uboya bamaqabunga (ama-trichomes), noma izicubu eziqinile ezenza kube nzima ukuthi izinambuzane zilume. Ukuzivikela kwamakhemikhali kufaka phakathi ama-metabolite esibili anobuthi noma aphazamise ukugaya kwezinambuzane. Ezinye izitshalo zingakhipha nama-compounds aguquguqukayo "abiza" izitha zemvelo lapho zihlaselwa, isibonelo, zidonsela ama-parasitoid abeka amaqanda emizimbeni yezibungu zezinambuzane.
Izitha zemvelo zifaka phakathi izilwane ezidla ezinye izilwane (isib., izimbungulu nezicabucabu), ama-parasitoid (ama-small wombs ahlala emizimbeni yezinambuzane), kanye namagciwane (isikhunta, amabhaktheriya, namagciwane athelela izinambuzane). Ukuba khona kwezitha zemvelo kuyisihluthulelo sokulawula kwemvelo. Kodwa-ke, ukusetshenziswa kwezibulala-zinambuzane ezibanzi kunganciphisa inani lezitha zemvelo ngokushesha kunenani lezilokazane, okungase kubangele ukuvela kabusha kwezinambuzane (ukuvela kabusha ngemva kokufutha) noma ukuvela kwezinambuzane zesibili ezazingasalawuleki ngaphambili.
Ukuguquguquka kwabantu kanye nomqondo womkhawulo wezomnotho
Izinhlobo zezinambuzane zithonywa ukuzalwa, ukufa, ukufuduka, kanye nokutholakala kwezinsiza. Emisebenzini yezolimo, ukuqonda lezi zindlela kuholele emqondweni womkhawulo wezomnotho: izinga lezinhlobo zezinambuzane noma ubukhali bomonakalo, uma ungalawulwa, obuzobangela ukulahlekelwa okukhulu kunezindleko zokulawula. Lokhu kusho ukuthi akuzona zonke izinambuzane ezidinga ukususwa ngokushesha. Ukulawula ngesikhathi okusekelwe ekubonweni kwensimu kuvame ukusebenza kangcono kunokufafaza okuvamile, okungadingekile.
Ukuqapha kuyisici esibalulekile. Ukubuka amaqanda, ama-nymph, noma izibungu ezingxenyeni ezithile zezitshalo, ukubeka izicupho ze-pheromone noma izicupho eziphuzi, kanye nokuqopha izimo zezulu kungasiza ukubikezela inani labantu. Lokhu kuvumela isenzo ukuthi siqondiswe ezigabeni zokuphila ezisengozini kakhulu noma ezikhathini ezibaluleke kakhulu.
Imiphumela yokuphatha: ekulawuleni okusimeme
Ukuqonda i-biology yezinambuzane kanye ne-ecology kuyisisekelo se-Integrated Pest Management (IPM). I-IPM igcizelela inhlanganisela yezindlela zokulawula ezisekelanayo: amasu amasiko (ukuhlanzeka, ukushintshaniswa kwezitshalo, isikhathi sokutshala, izinhlobo ezimelana nezifo), ukulawula ngomshini (ukukhetha ngesandla, ukubamba), ukulawula ngebhayoloji (ukulondolozwa kwezitha zemvelo, imithi yokubulala izinambuzane), kanye nokusetshenziswa okukhethayo nokuhlakanipha kwezibulala-zinambuzane zamakhemikhali uma kudingeka.
Isibonelo, uma izinambuzane zilimaza kakhulu ngesikhathi sesigaba sama-larval, amasu angase ahlose ukunciphisa impumelelo yokuchamisela amaqanda noma ukuphazamisa indawo yokuhlala yama-larval. Uma izinambuzane ziphuma ezinsaleleni zezitshalo noma enhlabathini, ekuhlanzeni insimu kanye nokulima kunganciphisa inani labantu abathola isivuno. Uma izitha zemvelo zisebenza kahle, ukutshala ama-refugia nokugwema izibulala-zinambuzane ezibanzi kungaqinisa ukulawula kwemvelo.
I-Penutup
Ibhayoloji kanye nemvelo yezinambuzane zezitshalo kubalulekile ekuqondeni ukuthi kungani kwenzeka ukuhlasela kwezinambuzane, lapho inani lazo landa khona, nokuthi yini eyenza kube nzima ukuzilawula. Ngokubheka izinambuzane njengengxenye yesimiso semvelo sezolimo, abalimi kanye nabasebenzi bezolimo bangathuthukisa amasu ahlakaniphile: ukusebenzisa ubuthakathaka bezinambuzane ezigabeni ezithile zokuphila, ukuqinisa indima yezitha zemvelo, ukuphatha indawo yokulima ukuze kuvinjelwe izinambuzane, kanye nokunciphisa ukuthembela ezibulala-zinambuzane. Ekugcineni, indlela esekelwe kubhayoloji kanye nemvelo ayigcini nje ngokwandisa isivuno kanye nokusebenza kahle kodwa futhi igcina impilo ye-agroecosystem kanye nokusimama kokukhiqizwa kokudla.
