Hrošč Cylas formicarius (Fabricius, 1798) je najpomembnejši škodljivec sladkega krompirja. Za preprečitev izpada pridelka je potrebno razviti ustrezen in učinkovit način integriranega zatiranja škodljivca. V ta namen je bil v Jamalpurju izveden poljski poskus s tremi ponovitvami za izbor najustreznejšega načina integriranega zatiranja škodljivca med osmimi obravnavanji. Rezultati so pokazali, da je bil najmanjši odstotek napada, tako v številčnosti škodljivca (2,94 %) kot v masi pridelka (3,22 %) ugotovljen v obravnavanju, ko je bil sladki krompir posajen prvega novembra in dvakrat osipan, poškropljen s karbofuranom 5G 15 kg ha-1 60 dni po saditvi, z namakanjem in spravilom gomoljev 130 dni po saditvi. Tržni pridelek (23,75 kg) in odstotek povečanja pridelka v primerjavi s kontrolo (50,86 %) sta bila največja v istem obravnavanju. Te ugotovitve nakazujejo učinkovito vključevanje različnih načinov zatiranja za učinkovito zmanjšanje napada sladkega krompirja od hrošča Cylas formicarius v Bangladešu.
