Ibhungane ejwayelekile kunamaglebhisi ewayini wonke yi-Phlyctinus callosus. Lezi zinambuzane zihlasela amaqabunga omvini namagilebhisi omvini futhi zidle izimbobo emaqabini nasehlathini. Qaphela imivini ekuqaleni kwenkathi ukuba kunomonakalo noma ukubukeka kwebhungane. Njengoba lihamba lisuka emhlabathini liya esihlahleni, ihlumela livame ukushiywa phansi ngokumelene nesiqu ukukhonza njengesilumkiso somonakalo wokudla okunomsoco. Amabhungane avela ezivini njalo unyaka wonke, kodwa shiya imivini ngokushesha lapho amaqabunga ewela umondlo wotshani olugoqekile - isitshalo esigcina amabhungane esihloniphekile.

Noma yikuphi ukulawulwa kwebhungane okuyingozi kufanele kwenziwe ngokwemigomo ye-IPW (Integrated Production of Wine Scheme). Isibonelo, lolu hlelo lukhuthaza ukuthi ama-pyrothroid akufanele afakwe. Lezi zinambuzane zinezinga elibanzi kakhulu elilimaza ezinye izitha zemvelo eziyizilokazane. Lokhu kungaholela ekuqhekekeni kwezinambuzane zesibili ezifana nolwembu obomvu. Ucwaningo luye lwabonisa ukuthi izinhlobo ezimbili zamabhungane ezihlukene zingalawulwa umuthi onamathayo.
