The species belonging to the genus Eurygaster Laporte are very
important from the economic point of view in Turkey. Eurygaster
integriceps Puton is one of the most harmful insects to wheat and
barley, but in addition it also attacks rye, oat and other graminaceous
plants. In Turkey it causes extensive damage especially in the eastern
south provinces, the amount of injury caused varying from year to
year and from place to place. In epidemic years the total amount of
the losses in some areas can reach up to 9o% if no control measures
are used. Eurygaster maura (L.) and Eurygaster austriaca (Schrk.),
found especially in Western Anatolia, cause damage approaching only
20% if no control measures are used, because their egg parasites are
very active in this part of the country. A good knowledge of this
genus is therefore very important to Turkish entomologists and agriculturists.
While working at the University of Aegea, Izmir-Turkey,
I paid speciaL attention to these insects and collected many specimens
whenever time was available. Amongst my material I find one new
species which is described below.
