摘  要:
In this paper, prevention pine caterpillars experiments are carried out by using transportation plane 11 to spray Bt biotic pesticides, and the suitable dosage, spraying time and modes are selected out, it provides reliable data for prevention over an extensive area in production. The results show that insect mortality may reach 93.4% by using low-capacity spray which the quantity of pesticide is 750g·hm -2 and spraying time is 198s, so it is an economical, effective and optimum selection for prevention pine caterpillars over an extensive area.
