Herbivores may interact with each other through resource competition, but also through their impact on plant defence. We recently found that the spider mite Tetranychus evansi down-regulates plant defences in tomato plants, resulting in higher rates of oviposition and population growth on previously attacked than on unattacked leaves. The danger of such down-regulation is that attacked plants c...

This study estimated the exposure to dust mites in various occupational environments in Croatia. In total, 29 occupational dust samples were collected: 10 from urban areas (offices, archive of an insurance company, tobacco, paper-recycling, fish-processing and textile plants, animal unit for experimental rats, winery), nine from rural areas (barley, hay, animal food and flour warehouses, tailor...

The role of herbivore‐induced volatile substances in prey‐finding by phytoseiid mites has been repeatedly documented using an olfactometer. The objective of the present paper is to test the hypothesis that movement by Phytoseiulus persimilis is affected by these volatiles even on plants. Two series of laboratory experiments were carried out. In the first series we stud...

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...
