Entomopathogenic fungi of Eurygaster integriceps Puton (Hemiptera: Scutelleridae): collection and characterization for development
Exploratory activities were done in Syria, Turkey, Iran, Uzbekistan, Kazakhstan, The Kyrghyz Republic, and Russia to locate entomopathogenic fungi of Eurygaster integriceps. Isolates from the entomopathogenic genera ...
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 ...
Resistance in wheat to a new North American–Russian wheat aphid biotype
The Russian wheat aphid (RWA), is a serious threat to wheat production worldwide. The identification of a new RWA biotype in the USA virulent to all commercially grown winter wheats poses new challenges to wheat breeders. ...
Biotypes of Hessian fly (Dipt., Cecidomyiidae) in Morocco
Hessian fly, Mayetiola destructor (Say), is the most important insect pest of wheat in Morocco, where host plant resistance has been used successfully for control. Our objective was to determine the frequency of Hessian ...
Field-based screening identifies resistance to Sunn pest (Eurygaster integriceps) feeding at vegetative stage in elite wheat genotypes
Sunn pest (Eurygaster integriceps Puton) is currently widely distributed in West and Central Asia
and Eastern Europe, but has not been found in Australia, Western Europe or North America. Climate
warming is known to promote ...
Embryo Development and Egg Hatching of Sitona crinitus Herbst (Coleoptera: Curculionidae) under Constant Temperature Regimes
The effect of constant temperatures (5, 8, 10, 15, 20, 25, 30 and 35°C) on embryo development period
and percentage of egg hatching of S. crinitus Herbst was determined in the laboratory. A significant negative
relationship ...
New resistance sources to Russian wheat aphid (Diuraphis noxia) in Swedish wheat substitution and translocation lines with rye (Secale cereale) and Leymus mollis
Russian wheat aphid is an important pest in many wheat growing countries of the world. Different resistance genes to the pest have previously been identified. However, some biotypes of the pest are virulent to most of these ...
First combined resistance to Hessian fly and Sunn pest identified in synthetic hexaploid wheat
Hessian fly, Mayetiola destructor (Say), and Sunn pest, Eurygaster integriceps (Puton), are the two most damaging insect pests of wheat in North Africa, West and Central Asia. Host plant resistance is the most environmental ...
Hyperpredation of local adults ladybirds on the eggs of Cryptolaemus montrouzieri a potential predator of carmine cactus cochineal Dactylopius opuntiae in Morocco
The mealybug destroyer Cryptolaemus montrouzieri has been introduced in many countries for biological control of mealybug species, recently the ladybeetle was tested on the biocontrol efficiency of Dactylopius opuntiae in ...
Sustainable management of chickpea pod borer. A review
The pod borer [Helicoverpa armigera Hubner
(Lepidoptera: Noctuidae)] is responsible for causing up to 90%
damage in chickpea due to its regular occurrence from the vegetative
growth to the pod formation stage. In order to ...
