Rodent Damage


Picture
A: Recently severed coffee verticals from rat chewing; one of them still hangs from the plant.
B: Rats hollowed out the stem and left teeth
marks on the woody tissue of stems in A.
C: Rats also feed on lateral branches of coffee (white circle).
D: Rats may feed on the green stem tissue of coffee verticals.
E: Several hanging and dead verticals on a coffee plant which was planted next to a forest.

Rodents, particularly rats, can cause damage to coffee branches by gnawing on the pith and cambium to feed on the moisture and nutrients within the branch.
Dr. Scot Nelson has information on rat damage to coffee and other crops in a past Hawaii Coffee Quarterly issue as well as in a CTAHR publication titled "Rat-feeding injury to plants in Hawaii".
