This paper describes the first record of Sejida (= Sejina) family Sejidae (superfamily Sejoidea) from Burmese amber, based on deutonymphs. Specimens were found in amber piece along with a wasp (Hymenoptera: Scelionidae), flies (Diptera: Ceratopogonidae) and thrips (Thysanoptera: Adiheterothripidae). traces back to mid-Cretaceous (ca. 100 Ma) represents not only oldest valid Mesostigmata, but it...

1. The hypothesis proposed by the fractal foraging model, that prey procurement by predators declines as habitat complexity increases, was tested. To evaluate this hypothesis, the effect of two prey species, second-instar larvae of Scirtothrips perseae Nakahara and Heliothrips haemorrhoidalis (Bouché) (both Thysanoptera: Thripidae), and environmental complexity on the functional response of the...

A new species from the genus Cosmolaelaps, with potential to control western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), were collected litter and remains of plant material on soil different rose greenhouses in The Netherlands. Collected specimens used initiate a laboratory colony. Subsequently, sample mites developmental stages analysed morphologically, by m...

1 The presence and abundance of arthropods were compared in three olive orchards under organic, integrated and conventional management regimes. In each olive orchard, trees were sampled in the canopy by beating branches and soil arthropods by placing pitfall traps. Contrary to expectations, the highest abundance of arthropods occurred in the integrated management orchard. The most abundant grou...
