Kunemihlobo elisumi eyahlukahlukeneko etholwa eSewula Africa, kodwana mihlanu kwaphela engaba nomthelela omumbi kwezomnotho esimini yamadiribe. Inomboro enengi, yentjalo khulukhulu utjani buyonakala. Lokha kunetjwalwe isimu etja yamadiribe, kubalulekile ukwazi bona ngiyiphi isimu esebenza njengeyemvelo entjalweni ze-margarodes. Njeke ukusuleleka kwemvelo kungakhandelwa. Umuthi i-The camel-thorn tree (Acacia erioloba), etholakala khulukhulu endaweni ye-Orange River esiphandeni seMpumalanga, sele itlhadlhulwe njengendawo yemvelo yengogwana ebizwa bona yi-margarode species.
Isitjalo semvelo sengongwana ezinye zeSewula Africa zisengakaziwa. Asikho isihlahla esiyikhemikhali esingasetjenziswa ukulawula iinunwana ze- margarodes eSewula Africa kwanjesi, kodwana kuphakanyiswa bona amatayera namanye amathulusi ahlwengiswe lokha nakafuduswa esimini wamadiribe asele asuleleke ngengogwana le asiwa kenye angakasuseleleki ngengondwana.
