Predicting the number of nymphal instars plus new-generation adults of the Sunn Pest from overwintered adult densities and parasitism rates
The present study evaluated the effect of overwintered adult density and egg and adult parasitism rates on the new-generation population densities of the Sunn Pest (Eurygaster integriceps Put.) under field conditions. We ...
Effect of egg parasitoid density on the population suppression of Sunn Pest, Eurygaster integriceps (Hemiptera : Scutelleridae), and its resulting impact on bread wheat grain quality
The impact of the density of Sunn Pest egg parasitoids, Trissolcus grandis Thomson (Hymenoptera: Scelionidae), at three levels of Sunn Pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae), infestation was assessed ...
Effects of planting date, varieties and insecticides on chickpealeaf miner (Liriomyza cicerina R.) infestation and the parasitoid Opius monilicornis F.
The effects of planting date, varieties and insecticides on chickpea leaf miner (Liriomyza cicerina R.) infestation and the parasitoid
Opius monilicornis F. were studied during the 1998 and 1999 cropping seasons. The ...
Susceptibility of some Chickpea accessions to infestation with leaf miner Liriomyza cicerina Rondani and its impact on yield
The susceptibility of some chickpea accessions to infestation with leaf miner Liriomyza cicerina Rondani was studied at the International Centre for Agricultural Research in the Dry Areas (ICARDA), Aleppo, Syria. Eight ...
Sources of resistance to Hessian Fly ( Diptera:Cecidomyiidae ) in Syria identified among Aegilops species and Synthetic derived bread wheat Lines
The Hessian fly, Mayetiola destructor
(Say), is a major pest of wheat in North Africa,
southern Europe, North America, and northern
Kazakhstan. It is believed this pest (like wheat)
originated in West Asia. The Syrian ...
First sources of resistance to Sitona weevil (Sitona crinitus Herbst) in wild Lens species
Lentil is one of the important cool-season food legumes grown in many countries in the Mediterranean region. But a substantial yield loss is observed every year due to various biotic stresses. The Sitona weevil (Sitona ...
Genetic diversity among summer and winter Beauveria bassiana populations as revealed by AFLP analysis
The genetic diversity of Beauveria bassiana was investigated by comparing 40 isolates collected from summer
and overwintering populations of Sunn pest from different areas in Syria and Turkey, using amplified fragment
length ...
QTL mapping identifies a major locus for resistance in wheat to Sunn pest (Eurygaster integriceps) feeding at the vegetative growth stage
Sunn pest (Eurygaster integriceps Puton) is the most destructive insect pest of bread wheat and durum wheat in West and Central Asia and East Europe. Breeding for resistance at the vegetative stage of growth is vital in ...
Development of SNP assays for hessian fly response genes, Hfr-1 and Hfr-2, for marker-assisted selection in wheat breeding
Background
The Hessian fly response genes, Hfr-1 and Hfr-2, have been reported to be significantly induced in a Hessian fly attack. Nothing is known about the allelic variants of these two genes in susceptible (S) and ...
Survey and biological study of Barley stem gall midge Mayetiola hordei Keiffer (Diptera: Cecidomyiidae) in Syria.
