[Damage-loss relationships and integrated control of 3rd instar larvae of Actias selene nigpoana Felder in planting area of Cornus officinalis Sieb. et Zucc].
In the present paper, the damage-loss model of Actias selene ningpoana to Cornus officinalis was tested and the results indicated that the yield loss rates obeyed the equation Y = 100 - EXP(4.6042 - 0.0315X). The economic threshold of the 2hd and 3rd instar larvae of A. selene nigpoana was then determined as 22 and 8 insects per tree respecitively. Suggestions for integrated control have been made based on the research of activities of A. selene ningpoana in the forest.
