FIRST RECORD OF THE PREDATORY BUG, NESIDICORIS TENUIS IN
ETHIOPIA
The zoophytophagous predator, Nesidiocoris tenuis Reuter (Hemiptera: Miridae) occurs in the
Mediterranean (Gabarra, et al., 2008) and Asia (Muniappan, et al., 2012). It predates on aphids,
whiteflies, thrips, mites, and eggs and small larvae of lepidopteran insects. In the absence of prey
insects, it will feed on host plants. In addition, it oviposits its eggs in plant tissue. In the
Mediterranean, it is inundatively released in greenhouses for control of whiteflies and the South
American tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae).
Tuta absoluta is a native of South America, and was accidentally introduced to Spain in 2006
(Urbaneja, et al., 2007). Since then, this highly invasive and destructive pest has spread to most of
Europe and the Mediterranean. It was reported in Ethiopia, in the Tigray region in 2012 and in the
Central Rift Valley in 2013 (Ayalew and Fekadu, 2013).
In November 2013, the USAID-sponsored IPM Innovation Lab (formerly CRSP) conducted a
Tuta absoluta workshop in Addis Ababa, Ethiopia to sensitize Eastern African countries
of its impending invasion. As a part of the workshop, a field trip was conducted to a
tomato field at Koka in the Oromia region on November 27, 2013. A single male specimen
of Nesidiocoris tenuis was collected by using a sweep-net over tomato plants. Its identity was
confirmed by Dr. Thomas J. Henry of the Systematic Entomology Laboratory in the
Agricultural Research Service of the U.S. Department of Agriculture, and the specimen
was deposited at the Smithsonian Institution’s National Museum of Natural History,
Washington, D.C. It was the first record of N. tenuis in Ethiopia and most probably in Africa.
