The effect of pyrethroid lambdacyhalothrin applications on the spatial distribution of phytophagous and predatory mites in apple orchards

AbstractLeaves were collected between 28 July and 10 September from 36 (1986) and 85 (1987) apple orchards, and examined for mites. Twelve species of Phytoseiidae were found: Amblyseius fallacis (Garman), Typhlodromus longipilus Nesbitt, A. andersoni (Chant), T. caudiglans Schuster, T. pyri Scheuten, T. pomi (Parrott), Phytoseius macropilis (Banks), T. herbertae Chant, A. driggeri Specht, A. finlandicus (Oudemans), T. conspicuus (Garman), and A. pusillus (Kennett), in order of frequency. The stigmaeid mites Zetzellia mali (Ewing) and Agistemus fleschneri Summers, a complex of erythraeid mites of Balaustium spp. and Hauptmannia spp., and tydeid mites, primarily Tydeus spp., were other common predatory species. Species of Tetranychidae, Bdellidae, Eriophyidae, Winterschmidtiidae, and Tarsonemidae, also were collected.Predatory mites were present each season in all abandoned orchards and in 43–74% of the commercial orchards. Their abundance in commercial orchards was compared with the use of insecticides applied only for control of the spotted tentiform leafminer, Phyllonorycter blancardella (Fabr.). Fewer (P < 0.05) phytoseiids occurred where pyrethroids were employed than in sites without pyrethroids, but differences were not found for similar use of the carbamoyl oxime, methomyl. Fewer (P < 0.05) stigmaeids occurred in sites treated with methomyl than in sites without methomyl, whereas such differences were not found for pyrethroid use.

The Family

AbstractDuring 2005–2007, 1,332 individuals of predatory mites were found in integrated and ecological orchards in Slovakia. Seven predatory mite species of the family Phytoseiidae, namely Phytoseius echinus, Phytoseiulus macropilis, Euseius finlandicus, Typhlodromus pyri, Paraseiulus triporus, Amblyseius andersoni and Neoseiulella tiliarum, were identified. Out of 1,332 individuals, 519 (39.0%) were found in the apple orchards and 813 (61.0%) in the pear orchards. Out of all predatory mite individuals, 460 (34.5%) were found in the integrated pest management system (IPM) and 872 (65.5%) in the ecological pest management system (EPM). In apple orchards, P. echinus was dominant and constituted 49.3% of the detected mites. In pear orchards, E. finlandicus was dominant and constituted 48.7% of the detected mites. Typhlodromus pyri was also abundant, especially in pear orchards. The other species were less abundant.
