摘要:为保证昆嵛山重要旅游景区赤松、红松的正常生长,维护景区沿线景观,于2009年开展昆嵛山腮扁叶蜂发生特点的调查,采用随机区组实验设计、利用无公害植物源杀虫剂1.2%烟碱·苦参碱乳油开展了昆嵛山腮扁叶蜂防治试验并确立了可靠的操作技术。结果表明:昆嵛山腮扁叶蜂在不同林分类型中的有虫株率差异极显著(F2.6=12.570,P=0.007),虫口密度差异也达到极显著水平(E.6=12.807,P=0.007);其中赤松纯林的有虫株率和虫口密度均最高。1.2%烟碱·苦参碱乳油(750—1500)g/hm^2,按照原药与柴油容量比1:9,1:12和1:53个浓度实施喷烟,15d后各林分内的腮扁叶蜂校正死亡率均达80%以上,浓度1:9处理后昆嵛山腮扁叶蜂校正死亡率显著高于其它2个浓度处理,因此,该浓度配比可以作为今后大面积防治腮扁叶蜂的最佳选择。
Investigations on the occurrence of Cephalcia kunyushanica Xiao and application of a botanical pesticide against the pest were carried out in Kunyushan National Forest Reserve in 2009 for the purpose of establishing a reliable operational technique of non-pollution control of C. kunyushanica. The results showed there were significant differences in the attacking rate( F2,6 = 12. 570 ,P =0. 007 )and larval densities(F 2,6 = 12. 807, P = 0. 007 ) among Pinus densiflora pure forest, P. koraiensis pure forest and P. densiflora-Quercus spp. mixed stand. Both indexes were highest in P. densiflora pure forest. Matrine-nicotine 1.2% EC mixed with diesel in the ratios(v: v)of 1:9,1:12 and 1:5 were applied for the control of the insect at the dosage of (750 - 1 500) g/hm2. The corrected mortality exceeded 80% in all treatments 15 days after the application and the mortality in the treatment in ratio of 1:9 was signifi- cantly higher than the other two treatments. Thus the treatment of 1:9 was recommended for large area control of C. kunyushanica in Kunyushan Forest Reserve.
