Hessian fly is an important pest of wheat on the North American continent and the temperate Mediterranean drylands. Yield losses caused by this insect in Morocco are the heaviest in the Mediterranean region and are estimated ...
Chemical composition, and insecticidal activities of four plant essential oils from Morocco against larvae of Helicoverpa armigera (Hub.) under field and laboratory conditions
Aromatic and medicinal plants are a rich source of molecules with insecticidal activities against many insect pests. The present study investigated the insecticidal activities of four essential oils against the third instar ...
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 ...
Antixenosis Resistance to Oulema melanopus (Coleoptera: Chrysomelidae) in Central Asian Wheat Germplasm
The cereal leaf beetle, Oulema melanopus (L.) (Coleoptera: Chrysomelidae), which is Eurasian in origin, is an emerging pest of agriculturally important cereal crops in western Canada, including wheat, oat, and barley. Among ...
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 ...
The Chickpea Pod Borer, Helicoverpa armigera (Hübner): Yield Loss Estimation and Biorational Insecticide Assessment in Morocco
Helicoverpa armigera (Hübner) is considered one of the most destructive insect pests of chickpea crops in Morocco; however, the extent of the yield loss it causes in Morocco is unknown. This study assessed the yield losses ...

Genome-Wide Association Mapping For Five Major Pest Resistances In Wheat
Insect pests cause substantial damage to wheat production in many wheat-producing areas of the world. Amongst these, Hessian fly (HF), Russian wheat aphid (RWA), Sunn pest (SP), wheat stem saw fly (WSSF) and cereal leaf ...
Conserved and Unique Putative Effectors Expressed in the Salivary Glands of Three Related Gall Midge Species
Species in the stem gall midge genus Mayetiola (Diptera: Cecidomyiidae) cause serious damage to small grain crops. Among Mayetiola species are Hessian fly (Mayetiola destructor Say), barley midge (Mayetiola hordei Keiffer), ...
Effect of temperature on the expression of resistance to Hessian fly (Diptera: Cecidomyiidae) in durum wheat cultivars
Hessian fly, Mayetiola destructor (Say) is a destructive insect pest occurring in many wheat growing areas of the world. The most effective management option for controlling Hessian fly is the use of resistant wheat cultivars ...
