Plants and insects
Lavender (L. angustifolia ) plants were harvested at different
developmental stages from a field belonging to the Institute of Botany,
Chinese Academy of Sciences, China. The three distinct stages were as
follows: B, bud stage: the petals were completely closed and green; I,
blossom stage: the 60% of flowers had opened and petals turned purple;
II, fade stage: the petals had shrunk and were ready to fall.
Four-week-old tobacco
(N icotiana
benthamiana )
andA. thaliana were grown in a green-house at
25°C
under a 16/8h light and dark photoperiod (200 μmol
m−2s−1).
Aphids (Myzus persicae ) and ladybugs
(Harmonia axyridis ) were
kindly provided by Prof. Su Wang (Beijing Academy of Agricultural and
Forestry Sciences) and maintained in a growth chamber (30×30×25 cm) at
25°C with a L16:D8 photoperiod feeding on tobacco plant.
