مقاومة العائل، الممارسات الزراعية والمكافحة الحيوية مكونات أساسية في برامج المكافحة المتكاملة للآفات; Host Plant Resistance, Cultural Practices, and Biological Control: Essential Components in IPM Programs
A number of pathogens persist in plant remains, and reproduce on them sexually, as they may persevere
on infected seeds, and these become sources of disease transmission from one field to another and from one field to ...
Massive Shift in Gene Expression during Transitions between Developmental Stages of the Gall Midge, Mayetiola Destructor
Mayetiola destructor is a destructive pest of wheat and has six developmental stages. Molecular mechanisms controlling the transition between developmental stages remain unknown. Here we analyzed genes that were expressed ...
A super-family of genes coding for secreted salivary gland proteins from the Hessian fly, Mayetiola destructor
We have previously characterized a gene coding for the secreted-salivary-gland-protein 11A1 (SSGP-11A1) from the Hessian fly,Mayetiola destructor (Say) (Diptera Cecidomyiidae). Here we report the cloning and characterization ...
Nymphal Stage of Sunn Pest at Application Time
Nymphal Stage of Sunn Pest at Application Time
Lethal and sublethal effects of the insecticides d-limonene, mineral oil, and potassium salts of fatty acid on Dactylopius Opuntiae potential predator Cryptolaemus Montrouzieri
In the last few years, Dactylopius opuntiae has seriously harmed the cactus pear in Morocco. Chemical control and predators are presently the predominant method used to control this scale pest. In this study the lethal and ...
Overwintering site of Sunn Pest
Overwintering site of Sunn Pest.
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 ...
Global Phylogenetics of Diuraphis noxia (Hemiptera: Aphididae), an Invasive Aphid Species: Evidence for Multiple Invasions Into North America
The Russian wheat aphid, Diruaphis noxia (Kudjumov) (Hemiptera: Aphididae), is globally one of the most devastating pests of bread wheat, Tritium aestivum L., durum wheat, Triticum turgidum L., and barley, Hordeum vulgare ...
A Massive Expansion of Effector Genes Underlies Gall-Formation in the Wheat Pest Mayetiola destructor
Gall-forming arthropods are highly specialized herbivores that, in combination with their hosts, produce extended phenotypes with unique morphologies [1]. Many are economically important, and others have improved our ...
Distribution, population dynamics and damage of Hessian fly, Mayetiola destructor (Diptera: Cecidomyiidae) in North Tunisia
A three years survey and monitoring studies (2013–2014–2015) were carried out through 4 regions of north Tunisia in order to follow the evolution of the distribution, the frequency of occurrence and damage caused by the ...
