| Abstract: | Splendid knot-horn moth (Dioryctria pryeri ragonot) is a bore pest which is subordinate to Lepidoptera, Pyralidae, Phycitinae. It bores the cones and tender branches of Pinus Taiwanensis Hayata in Huadingshan Forest Farm of Tiantai County, Zhejiang Province, with the result that the new growth withers and the seed yield decreases. In Tiantai county, splendid knot-horn moth produces one generation in a year, and the larva in the stage of 2nd instar overwinters. The adult emerges firstly in the last ten days of June, reaches peak from the middle ten days of July to the first ten days of August, has a clear photokinesis. The average egg number of a female adult is 61, the ratio of male and female 1:1. The hatching of larva begins in the second ten days of July. Five instar larva is high in boring speed and quick in movement. |
