Effect of colours on oviposition preference of the oriental fruit moth, Grapholita molesta Busck
Acta Ecologica Sinica 34 (11), 2971-2977
Abstract: The oriental fruit moth (OFM), Grapholita molesta Busck is one of the major fruit tree pests which lay their eggs on the leaves of young peach shoots. In order to find out the roles of the host colour in oviposition orientation, we conducted a comparative study to reveal effects of 12 different colours (red, pink, light pink, orange yellow, deep yellow, light yellow, green, deep green, light green, blue, purple, brown) on oviposition preference of adults using the color cardboard to simulate the host colours outdoors. The results showed that colour affected the oviposition preference significantly. OFM preferred light yellow and light green for laying eggs, with oviposition preferences of 68.9% (white reference) and 63.8% (black reference) on light yellow cards, 64.1% and 65.5% on light green cards. OFM showed a certain avoidance to blue and light pink cards, with oviposition preferences of 47.7% and 40.4% on blue cards, as well as 47.2% and 42.7% on light pink cards. Colour also affected the fecundity significantly.
