Abstract The cereal leafminer, Syringopais temperatella Led. is a destructive insect pest of wheat and barley in the field,
and causes economic damage to these crops in many countries including Jordan. The insect feeds on plant foliage and
eventually leads to a sharp decline in production. Management of agricultural pests is undoubtedly considered one of the most
important farming practices that should be taken by growers. Continuous use of chemical insecticides is neither economic nor
sustainable, and poses risk to humans, animals, beneficials and their environment. One of the promising alternatives is the use
of integrated pest management (IPM). IPM was proven to be a successful, sustainable, effective, economic and
environmentally friendly control strategy for pests. However, to the best of our knowledge, no an integration published work
was found to cover the status, biological and ecological aspects, current and future control options of S. temperatella.
Therefore, this review paper was prepared to better understanding the biological and ecological aspects of S. temperatella,
and to develop management strategies to successfully suppress its population. Also, this review aims to improve wheat and
barley production in our region, through the introduction of IPM practices such as resistant plant cultivars, natural enemies,
bio-insecticides and cultural practices to control S. temperatella, since this paper is the first to tackle some of IPM measures
of this pest. However, in this review, the geographical distribution, host plant spectrum, life cycle and biology of the pest,
susceptibility/resistance of hundreds of wheat and barley cultivars/accessions, role of oxalic acid, crop rotation, ploughing,
right chemical and time, parasitoids, bio-insecticide and environmental factors were thoroughly discussed. All these aspects
are fundamental components of IPM, and should be taken into account in any future IPM program to control S. temperatella.

1. Introduction
Wheat and barley are the principal food crops for
hundreds of millions of people in the predominantly mixed
crop-livestock farming systems world-wide. The grain yield
of these crops achieved by farmers in arid and semi-arid
regions in West Asia and North Africa is low with large
variability from year to year [1]. Low grain yield and even
crop failure are common in Jordan [2]. Jordan is not
self-sufficient in the production of wheat and barley, and the
self-sufficiency ratio is only 1.8% and 6.1%, respectively. In
2010, the country imported 1,076,650 and 447,332 tons of
wheat and barley, respectively [3] to cover the national needs.
Both crops are classified as low-input crops to farmers,
though, farmers can’t accept much loss of their yield due to

any causal agent. The demand on Jordanian agriculture to
rapidly increase cereals' production should be effectively
addressed through modifications in the present control
measures, and adaption of proven newer protection
measures.
In addition to the environmental stresses (mainly drought)
which are main causes for low productivity of wheat and
barley [4, 5], insect pests cause serious and yield loss to these
crops [6]. Hundreds of insects have been monitored on wheat
and barley worldwide. While most of these insects cause
insignificant damage, others are considered major limiting
factors that cause serious reduction in wheat and barley
grains and forage production [7, 8, 9]. Some insect pests are
specifically adapted to wheat and barley and their relatives
and to the set of environmental conditions where wheat and
barley are grown. As some agricultural practices eliminate
natural regulating forces that would normally check their
populations, many insect-pest populations have erupted into
severe outbreaks wreaking near-total destruction on the
crops they infest [6].
