Abstract:

Spiders, particularly assemblages of species, have been shown to be effective in reducing pest insects and crop damage in field crops and orchards. We investigated the potential for a single jumping spider species to reduce pests in a greenhouse setting. We placed three treatments in large enclosures: 1) control treatment of only sweet basil, Ocimum basilicum L.; 2) sweet basil and a phytophagous pest, fourlined plant bug, Poecilocapsus lineatus (F.) (Heteroptera: Miridae); and 3) sweet basil, fourlined plant bug, and jumping spider Phidippus clarus (Keyserling 1884). After 1 wk, jumping spiders reduced the number of plant bugs. Plants exposed to plant bugs alone were significantly shorter than either control plants or plants exposed to plant bugs and spiders. Chlorophyll concentration did not significantly differ across treatments. We discuss the feasibility of using P. clarus and similar salticids in biocontrol.
