松大蚜在城市绿地发生规律研究

在连续4 a观测松大蚜在辽南地区城市绿地发生情况基础上,记述了松大蚜在辽南城市绿地中的发生规律,认为松大蚜在城市绿地中偶尔发生,轻易不会暴发成灾。一旦发生量大,影响了松树的生长和观赏效果,也有诸多制约因子,可防可控。其中最有效的控制因子是一种鸟类--麻雀,对其控制起到至关重要的作用。在此基础上,提出了对该害虫的综合治理方法,为松大蚜在城市绿地中的控制提供了有力的防治依据。

Study on the Occurrence Regularity of Cinara Pinitabulaeformis in Urban Green Space

Based on the observation of the occurrence of Cinara Pinitabulaeformis in the urban green space in southern area of Liaoning Province for 4 years, this paper described the occurrence regularity of Cinara Pinitabulaeformis in the urban green space in southern Liaoning Province. It is considered that Cinara Pinitabulaeformis occurs occasionally in the urban green space,so it is not easy to cause a disaster. Once the occurrence of a large number which may have an impact on the growth of Pine and ornamental effect,there are many constraints which can control them. Among these constraints, the most effective control factor is a bird-sparrows. On this basis, the integrated control method of the pest was put forward, which provided a strong basis for the control of Cinara Pinitabulaeformis in the urban green space.
