Table 2 Influence of ageing-conditions, hay concentration and conspecific odors on attraction to infusion-baited AGO-Bs

From: An improved autocidal gravid ovitrap for the control and surveillance of Aedes aegypti

Experiment Infusion age (days) Infusion attractant Avg. females per trap (95% CI) F P-valueb
1 - Infusion fermentation conditions 7 Anaerobically-fermented 46.1 (40.7, 51.6) 5.1 <0.05
  In situ (AGO-A) 37.4 (31.9, 42.8)   
  In situ (AGO-B) 36.3 (30.9, 41.7)   
2 - Hay concentrationa 7 In situ (1×) 12.1 (9.6, 14.6) 0.8 NS
  In situ (2.2×) 10.1 (8.1, 13.1)   
  28 In situ (1×) 19.4 (17.0, 21.7) 3.8 NS
   In situ (2.2×) 16.2 (13.8, 18.6)   
3 - Addition of conspecific larvae 7 In situ 34.9 (29.1, 40.6) 1.5 NS
  In situ + 50 larvae 39.7 (33.9, 45.4)

  1. a 1× infusion concentration = 3.8 g of hay per l of dechlorinated tap water, 2.2× infusion concentration = 8.3 g of hay per l of dechlorinated tap water. A 1× concentration was used to prepare in situ infusions in experiments 1 and 3.
  2. b NS: not significant (P ≥ 0.05).
