Table 1 Numbers and proportions of pupae and adults obtained for the different experimental groups.

From: Cardiocladius oliffi (Diptera: Chironomidae) as a potential biological control agent against Simulium squamosum (Diptera: Simuliidae)

Experimental group (C. oliffi:S. squamosum) Number of larvae introduced in the rearing systems Number of S. squamosum pupae (% of larvae) Adults S. squamosum emerged
  C. oliffi* S. squamosum   Total number (Mean + SD) % of larvae % of Pupae
Control (0:25) 0 150 96 (64) 81 (14 ± 3.94)a 54.00 84.38
Treatment ii (1: 5) 30 150 55 (36.6) 22 (4 ± 2.94)b 14.67 40.00
Treatment iii (1: 2) 78 150 42 (28.0) 15 (3 ± 2.16)b 10.00 35.71
Treatment iv (1: 1) 150 150 28 (18.6) 1 (0.20 ± 0.48)b 0.67 3.57

  1. Values followed by different letters are significantly different (p < 0.05).
  2. *There was no significant difference between the proportion of adult C. oliffi that emerged from the control and the proportion of adult of the same species emerging from the various treatments
