Extra resources for Coffee pests, diseases and their management
Tanzania Tanzania has about 220,000 ha of coffee of which less than 10% is robusta, grown in the west of the country around Bukoba; 90% is arabica, grown mainly on the slopes of mount Kilimanjaro in the districts of Arusha, Oldeani and Moshi. Estates account for about 7000 ha of arabica and the remainder is under smallholdings. Ofﬁcial estimates put the number of families who derive at least part of their income from coffee at 270,000. During the 1980s, considerable resources were devoted to coffee research and development, and two large processing factories were built.
The main varieties grown are Catuai, Caturra and Colombia – a multi-line variety from Hybrido de Timor/Caturra crosses that was introduced from the late 1980s to combat leaf rust. The main disease problems are rust, South American blight (Mycena citricolor) and pink disease (Erythricium salmonicolor). The main insect pest is the berry borer (Hypothenemus hampei). The world crisis in coffee prices has seen the export value of Colombia’s coffee in 2001 decline by 50% from the average value from 1994 to 1999.
Wrigley, G. (1988) Coffee. Longman (Tropical Agriculture Series), Harlow, UK, 639 pp. 3 Stem- and Branch-borers Introduction Insects in a number of families of the Coleoptera (beetles), Lepidoptera (moths), Isoptera (termites) and Hymenoptera (bees and wasps) can tunnel into and damage woody stems and branches of the coffee plant. The xylem tissue forming the woody part of the stem is composed mainly of cellulose and lignin, which cannot be digested directly by most insects, although some have developed enzymes that can break down these substances.
