A study by World Agroforestry Centre found that the black coffee twig borer in coffee systems with older and taller shade trees have less infestation than younger systems with smaller trees.

Researchers in a study, Influence of shaded systems on Xylosandrus compactus infestation in Robusta coffee along a rainfall gradient in Uganda also found that the twig borer infestation is stronger in high rainfall zones as well as with shade composed predominantly of the legume tree species.

Meanwhile, at Kituza, a number of coffee wilt disease-resistant varieties developed using tissue culture and stem cutting through clonal propagation are now available as part of efforts to fight the weevil. Magambo told URN that the varieties known as Kituza KR1–7 and KR8-9 have traits conferring resistance to coffee wilt disease.
