abstract
Included were the spider mites Tetranychus spp, western flower thrips Frankliniella occidentalis, big-eyed bugs Geocoris pallens and G. punctipes, and the minute pirate bug Orius tristicolor. Association patterns were modeled using a log-linear statistical model. Co-occurrence patterns for most species pairs were significantly nonrandom and mostly positive and were seen to change over the season. In general, associations tended to become increasingly positive (or less negative) as the season progressed. Pesticide treatments did not affect associations. -from Authors
