Sithole izibungu ezincane ezimhlophe ezifika ku-millimeter ubude ku-greenhouse yethu. Ekuqaliseni kokuqala kubonakala sengathi wonke umbhede ufafazwa nge-semolina. Lapho nje sizama ukuwaqothula! Inhlabathi yayifafazwa nge-dichlorvos, iniselwa ngesisombululo se-potassium permanganate ngisho ne-creolin.
Izibungu umfundi wethu azibhala ngazo zingokuhleleka kwezipikili (collembole - collembola). AmaCollembolans avele eMhlabeni phambilini kunezinambuzane nezitshalo eziphakeme, ngakho-ke azivumelanisa nezimo ukuze zidle i-algae, amakhowe, ama-lichens. Kaningi bahlala phakathi kwezinsalela zokubola zesitshalo nangaphezulu kwenhlabathi, kepha zingakhuphuka zijule. Okungatholakali kakhulu ezitshalweni nasemachibini.
I-Collembolas, noma ama-springtails (ama-Springtail)Izinhlobo ezihlala emhlabathini zimhlophe; lezo ezihlala ezitshalweni eziluhlaza ziluhlaza okotshani; ehlathini lehlathi - ngwevu futhi nsundu; Kunemibala egqamile noma nge-sheen yensimbi. Ubude bomzimba wesibungu buyi-1 mm. Ikhanda elinezimpondo namehlo ezinhlangothini. Amabhuzu amathathu wemilenze akuvumela ukuba uqhubeke ngenkuthalo ebusweni, futhi ngenxa "yemfoloko" ngaphansi kwesisu, uze ugxume. Ama-whitemberg amhlophe ahlala emhlabathini awanayo “iforum yokugxuma”, angakwazi ukukhamba kuphela ngosizo lwemilenze esifubeni emifushane.
AmaColumbolans azala ngendlela eyinqaba. Abesilisa babeka ama-spermatophores ngesimo samaconsi (uketshezi lwesisu) ezihlahleni. Abesifazane bathwebula ama-spermatophores ngokuvuleka kwabo ngokobulili futhi, emva kokukhulelwa, babeka amaqanda ezindaweni ezinomswakama Ama-collembolas amancane, afana nabantu abadala, aphuma emaqanda.
I-Collembolas, noma ama-springtails (ama-Springtail)I-Collembol ayinamahloni ngokupholisa, iyasebenza ngisho nasenhlabathini eqandisiwe, futhi ukuthuthukiswa kwamaqanda akuyeki kufinyelele ku-2-3 °.
Ingabe ama-collembolas ayingozi? Yebo futhi cha.
Ngakolunye uhlangothi, i-colembol yokuphila ithuthukisa inhlabathi. Bazondla ngokuwohloka kwezinsalela zezinto eziphilayo, amagciwane, izidumbu zezilwane. Enyakatho, bachitha amaqabunga awileyo, bacebisa inhlabathi ngezakhi zomzimba.
I-Collembolas, noma ama-springtails (ama-Springtail)Kodwa-ke, kukhona futhi nabamele bama-collembolas amhlophe adla ezimpandeni zezithelo zezitshalo. Ngokungangabazeki, zivimbela izitshalo zombili eluhlaza kanye nasengadini. Ngakho-ke, ukulahleka kwezitshalo.
Yini ukweluleka? Uma ucabanga ukuthi ukuthuthukiswa kwamaqanda we-coupmbol kungenzeka kuphela endaweni enomswakama futhi athinta kakhulu ukomisa, zama ukomisa umhlabathi lapho uthatha ingxenye yawo lapho kugcina ukushisa khona (eshidini lokubhaka emlilweni noma emashidini ensimbi elangeni).
