Study on the parasitoids ofPissodes nitidus Roel

A systematic observation and intensive study on the parasitoids ofPissodes nitidus were made in Langxiang and Xin'qing Forestry Bureau in Xiaoing'an Mountain area in 1996–1999, including the diagnosis, life history, biological characteristics ofEurytoma sp. and parasitoid complex ofPissodes nitidus. There were about 70 species of parasitoids onPissodes nitidus, including Eurytomidae, Ichneumonidae and Braconidae etc. Among them,Eurytoma sp. is a dominant species and a braconid,Ipobracon sp. is a subdominant species, and they play an important role in controlling the pest.

Study on biological and ecological characteristics ofIps subelongatus Motsch

Ips subelongatus Motschulsky were raised indoors and in the field using fresh baits for study of biological and ecological characteristics during 1992–1994. The life cycle of the pest in Lishu County, Jilin Province was described. The study results indicated that temperature was a main factor affecting the development ofIps subelongatus. The initial temperature for development of egg, larva, pupa and adult was 6.1, 8.0, 10.3 and 9.8°C, respectively. To complete one-generation needs, respectively, 48 d at temperature of 18°C, 39 d at 20°C and 33 d at 22°C. The pest has different number of generations in different area as a result of temperature change. In Jilin Province, it generally has three generations, except that some individuals have 2 generations. The nature enemies for this pest areThanasinus substriatus, Tomimicobia seitneri Ruschk,Coeliodes sp. etc. Foundation item: This paper is part of key subject of the Ministry of Forestry (formerly)—The Systematic Control Technique ofIps subelongatus Motschulsky.

速扑杀防治云南木蠹象试验初报

云南木蠹象是鞘翅目象甲科的一种蛀干害虫,危害健康云南松。2002年在贵州威宁暴发危害,当时除了人工清理枯死枝条、枯死植株外,无有效防治措施。在羽化期喷施1000倍40%速扑杀乳油两次后,云南木蠹象的危害指数平均下降11.08,防治效果可达50.6﹪。通过试验,我们认为速扑杀可用在虫源地控制虫口密度,连续2￣3年使用可以抑制虫害蔓延扩散。

Relationship between trophic component of different poplar strains and occurrence ofSaperda poplnea

An experimental area of poplar was established in Songyuan of Jilin Province in 1999 for testing the resistance of different poplar stains toSaperda poplnea. Incidence ofS. poplnea on ten poplar strains were investigated, and the main trophic component of branches of these poplar trees were measured and analyzed in April 2001. The results showed that there existed significant difference in population size ofS. poplnea on different poplar strains, and the branches of these poplar strains have significant difference in nutrient component and content of amino acids. The population size of this pest had a significantly positive correlation with dissolvable total sugar and water content but had no significant correlation with content of total nitrogen and protein nitrogen. Foundation Item: This paper is part of the subject of integrated control of longicorn of poplar for mainly focusing on pest resistance, which was supported by Jilin Provincial Forestry Department (96-010).
