Comparative toxicity of different chemical and biological insecticides against the scale insect Dactylopius opuntiae and their side effects on the predator Cryptolaemus montrouzieri
The contact toxicity of various chemical and biological pesticides for the first and second instar nymphs and adults of the Opuntia cochineal scale insect Dactylopius opuntiae and the predator ladybird Cryptolaemus ...
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 ...
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 ...
Selection of new high yield potential bread wheat lines resistant to Hessian fly, Mayetiola destructor (Say), in Morocco
Wheat (Triticum sp.) is the main staple food of the Moroccan population. However, the
crop is attacked by several pests and diseases. Hessian fly is the most serious pest, causing
an average yield loss of 30% yearly. In ...
Grain yield losses due to leaf miner (Liriomyza cicerina R.) in winter- and spring-planted chickpea in Morocco
Chickpea leaf miner (Liriomyza cicerina R.) is one of the main insect pests damaging chickpea (Cicer arietinum L.) inthe Mediterranean region.This study assessed yield losses caused by the chickpea leafminer on four improved ...
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 ...
