Carotenoids underlie many of the vibrant yellow, orange, and red colors in animals, and are involved in processes ranging from vision to protection from stresses. Most animals acquire carotenoids from their diets because de novo synthesis of carotenoids is primarily limited to plants and some bacteria and fungi. Recently, sequencing projects in aphids and adelgids, spider mites, and gall midges...
Tetranychus urticae Koch, is known as a two-spotted spider mite and the most obtrusive polyphagous non-insect pest that causes havoc on horticultural crops. Cucumber cultivation threatened by variety of infestations, among which mites cause damage to crop. The efficiency six different chemical acaricides against T. in cucumber grown polyhouse was examined. results acaricide evaluation trial rev...
Plants infested with the spider mite Tetranychus urticae Koch, may indirectly defend themselves by releasing volatiles that attract the predatory mite Phytoseiulus persimilis Athias-Henriot. Several plants from different plant families that varied in the level of spider mite acceptance were tested in an olfactometer. The predatory mites were significantly attracted to the spider mite-infested l...
Monitoring of Acaricide Resistance in Two Spotted Spider Mite, Tetranychus urticae Koch in Carnation
The two-spotted spider mite, Tetranychus urticae Koch, has caused significant damage to vineyards in the valley of São Francisco River Brazil. Neoseiulus idaeus Denmark & Muma is one most abundant species predatory mites on vines this region. This study evaluated population growth rates T. leaves two grape (Vitis vinifera L.) cultivars (‘Italia’ and ‘Superior Seedless’) jack bean [Canavalia ens...
The negative cross-talk between induced plant defences against pathogens and arthropod herbivores is exploited by vectors of plant pathogens: a plant challenged by pathogens reduces investment in defences that would otherwise be elicited by herbivores. This negative cross-talk may also be exploited by non-vector herbivores which elicit similar antiherbivore defences in the plant. We studied how...
