Fan Hui · Journal of Gansu Forestry Science and Technology · 2005
Through field observing and simulating natural environments to raise Acantholyda posticalis. And determined its duration of different insect forms, quantity of nibbled leaves by larva and losing quantity of non-nibbled leaves after the leaves have been damaged, established index value of control of different instar larva of Acantholyda posticalis on single branch with length of 30 cm of Pinus tabulacfarmis, studied its forecasting methods in terms of growth law, developing process and effective quantity of insect. All of them above provided feasible techniques for its control method and right time of control.
