Fig. 1From: Combined use of zoophytophagous mirids for sustainable biological protection of greenhouse tomato cropsMean (± SE) number of (A) N. tenuis, (B) M. pygmaeus, and (C) D. errans adults per plant depending on the initial density of M. pygmaeus introduced and with or without D. errans. ‘Mp10′ 10 initially introduced M. pygmaeus; ‘Mp15′ 15 initially introduced M. pygmaeus; ‘De’ D. errans present. Vertical dashed lines show the time periods used in statistical tests and coinciding with estimated insect generation times. Different letters show significant differences between treatments or groups of treatments within each time period. N = 40 replicates per treatment and per week (insects counted on 10 plants per tunnel with four tunnels per treatment)Back to article page
