The graphs show the sticky card weekly whitefly counts for all 3 growers and the percentage of poinsettia plants each week that were found to have whitefly present (very rarely was there more than 1-2 whiteflies found per plant). The main point of interest for Grower A is the spike in whitefly numbers on the sticky cards at week 37. Normally, these sorts of numbers would result in the biocontrol program being terminated. However despite the sticky card numbers and the fact that adults were becoming easier to find on the plants, there was very little evidence of reproduction. No egg-laying, no sign of immature whiteflies. From week 37 onwards, the adult numbers declined and there was still no sign of whitefly eggs, larvae or pupae on the poinsettias.
