List of symptoms / signs

Growing point - internal feeding; boring
Stems - dieback
Stems - internal feeding
Stems - wilt
Whole plant - internal feeding
Whole plant - plant dead; dieback

Symptoms

Because of internal boring, branches and twigs wilt quickly and then become brittle and easily break off; there are holes visible from which the frass is exuded.

Prevention and control

Control is often not practical because of the large number of host species used by the pest. It is also complicated as Z. coffeae is one of several stem-boring pests. The removal and burning of dead and dying branches and seedlings will help to reduce pest numbers.

Chemical control can be effective. Abraham and Skaria (1995) found that swabbing the main stem with a suspension of carbaryl was effective as a prophylactic measure. However, other studies have found such measures ineffective.

Impact

Chang (1984) describes Z. coffeae as one of the most important pests of grapevine in Taiwan.

In Karnataka, India, of seven 3-4 year old plants infested by Z. coffeae, four died. Mortality occured in instances where the main stem had been attacked (Sathiamma and Bhat, 1974).

Hanif and Wali-ur (2000) conducted a survey in different valleys of Dir District, Pakistan, to record the extent of damage caused by Z. coffeae to walnut trees. The pest caused heavy damage in the Sultan Khel valley where tree infestation was 90-100% in Sairai and 80-90% in Kotkai villages. The number of dry branches per tree ranged from 5 to 15 at Sairai and 5 to 10 at Kotkai.
