“…The data have been kindly provided by Dr. Mark Stevens, Yanco Agricultural Institute. A full description of the experiment is given by Stevens et al [1999]. Bloodworms are a significant pest of rice in the Murray and Murrumbidgee irrigation areas and damage can result in poor establishment and substantial yield loss.…”

“…Each tray contained a total of 32 seedlings and the trays were paired so that a control tray (no bloodworms) and a treated tray (bloodworms added) were grown in a controlled environment room for the duration of the experiment. After this, rice plants were carefully extracted, the root system washed and root area determined for the tray using an image analysis system described by Stevens et al [1999]. Two pairs of trays, each pair corresponding to a different variety, were included in each run.…”

“…The role of C. tepperi as a pest of directly-sown rice crops has been well established (Jones, 1968;Stevens et al, 2000), however many other chironomid species occur within crops during the first few weeks after sowing. In this study, we examined the composition of chironomid communities developing in experimental rice fields that were not exposed to any agrochemical applications.…”

“…In these first days after flooding only small amounts of algae (Roger & Reynaud, 1976;Anastácio et al, 1999c) and aquatic macroinvertebrates are present (Simpson et al, 1994;Leitão, 2002). Of these, the chironomids are one of the most important groups because of their rapid colonisation, the negative impact they have on rice (Grigarick, 1984;Tinarelli, 1989;Simpson et al, 1994;Stevens et al, 2000) and their susceptibility to crayfish consumption…”
