During this survey in southeastern France, there were found three new alien spider mites species: Aponychus corpuzae on Phyllostachys sp. and Semiarundinaria yashadake; the Persea mite Oligonychus perseae americana most probably also Vitis vinifera; Stigmaeopsis nanjingensis S. yashadake. In connection with records of A. corpuzae, we propose an identification key for world species genus Aponych...

Mites of family Erythraeidae are parasites in their larval stage and predators in their post-larval stages on a variety of arthropods, among which are important pest species. During 2011-2013, in a faunistic survey of mites associated with beetles of the family Chrysomelidae in Oil and Gas company of Gachsaranregion, Iran. Specimens were preserved in AG (alcohol 75%, glyserin 5%), cleared in la...

Life history theory predicts that females should produce few large eggs under food stress and many small eggs when food is abundant. We tested this prediction in three female-biased size-dimorphic predatory mites feeding on herbivorous spider mite prey: Phytoseiulus persimilis, a specialized spider mite predator; Neoseiulus californicus, a generalist preferring spider mites; Amblyseius anderson...

Abstract Twospotted spider mite, Tetranychus urticae Koch (Trombidiformes: Tetranychidae), is an important, worldwide pest of watermelon, Citrullus lanatus L. (Thunb.) Matsum. & Nakai (Cucurbitales: Cucurbitaceae). Feeding results in chlorotic spots and leaf necrosis, which can substantially reduce yields. In T. managed solely with acaricides. Issues acaricide resistance pesticide label res...

Agriculture is the most important economic activity around world with its contributions reflected by share in gross domestic product of countries. It ensures food security, provides raw materials for many industries and employment opportunities. Today, pest diseases are among main challenges plaguing agricultural sector. More specifically, phytophagous mites devastating economically crops world...

Current understanding of animal phylogeny has provided new insight on the evolution of the ancestors of the Euchordata (cephalochordates1vertebrates). Modern, adult euchordates possess a capacity for swimming, displacing themselves through water independently of currents. Swimming is achieved by the presence of a fin and axial body movements. However, the classic hypothesis on the origin of euc...

Inflow of matter and organisms may strongly affect the local density and diversity of organisms. This effect is particularly evident on shores where organisms with aquatic larval stages enter the terrestrial food web. The identities of such trophic links are not easily estimated as spiders, a dominant group of shoreline predator, have external digestion. We compared trophic links and the prey d...

Leprosis is a serious disease of citrus caused by Citrus leprosis virus C (CiLV-C, genus Cilevirus) whose transmission is mediated by false spider mites of the genus Brevipalpus. CiLV-C infection does not systemically spread in any of its known host plants, thus remaining restricted to local lesions around the feeding sites of viruliferous mites. To get insight into this unusual pathosystem, we...
