First, De Maozhi Deer caterpillar Dendrolimus kikuchii Mats. Host South Asia pine △ Simao pine, Yunnan oleander, Pinus yunnanensis, Masson pine.

Degree of damage +++ Harm situation June 1966, slaughtered for the first time found slash pine caterpillar disaster. The tree is the victim of the natural plantation of South Asia pine, about 9,000 strains, accounting for about 60% of the total number of trees in this area. Serious victim strains, more than half of the needles lost, and even all were eaten. In 1977 continue to disaster, damage trees about one thousand strains. Biological pest damage occurred, the elevation of 440 meters. Three generations a year, the larvae winter, but do not sleep. Inter-generational larvae, cocoon pupation began in late March, adult emergence in mid April. The first generation larvae appeared in late April,
