All ticks attached were counted, and all nymphs and adults were collected into tubes with damp paper and transported live to the laboratory. Twenty-four hours later, the plants were checked to see if the founding aphid had settled and any nymphs produced were counted. The effect between treatments was dramatic, with no nymphs found on control trees (table 3). The majority of larvae moult to nymphs that overwinter as flat nymphs. Mortality of nymphs in all other treatments was less than 7%. Approximately 12 weeks were spanned from the time that the first nymphs and then first adults were collected. Ninety-seven females, 66 males, 21 nymphs and one larva were identified. Some of the attacked nymphs died and desiccated during the rearing process and thus could not be dissected for parasitism. Twenty nymphs in the fourth arena were dissected each day for four days consecutively to assess the stages of the competition between the species. The dance was also a poignant reminder of the difficulties that the young nymph would face on the path to immortality. Leaf disks were removed from the ethanol and assessed individually under a dissecting microscope for numbers of eggs and nymphs. Plants were kept until surviving nymphs had reached third or fourth instar or adulthood (10-15 days after treatment). The nymph crawls above ground, where it unfolds its wings and becomes the winged form capable of spreading the phylloxera above ground. The difference in the numbers of nymphs on coppiced versus control trees was compared using a chi-square analysis. These examples are from corpora and from sources on the web.
