Eksempler på nymph

• Daily fecundity (number of nymphs produced per adult per day) varied with time for both aphid species and in each experiment (fig. 2).

• 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 clear age structures of these populations are corroborating evidence of two separate cohorts of both nymphs and adults (fig. 2).

• 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.
