Lantana camara L. (Verbenaceae) is a weed of significant concern in many tropical and subtropical countries. This work aimed to quantify the combined impact of the established suite of lantana biocontrol agents on plant growth under field conditions in an inland area with a continental climate in South Africa. An insecticidal exclusion method was employed to compare plant growth parameters and agent damage between exclusion plants and biocontrol plants. Despite failing to maintain exclusion plants completely biocontrol agent-free, leaf damage was 44% greater, and side-stem production 16% less, in biocontrol compared to exclusion plants. There was a positive relationship between leaf damage and reduction in side-stem production over the study period. Overall, insecticidal exclusion, though only partially effective, showed that the established suite of lantana biocontrol agents is having a measurable growth-inhibitory impact on the target weed.

生物防治剂对南非内陆地区马Lan丹的影响

马tana丹在许多热带和亚热带国家，L。（马鞭草科）是一种备受关注的杂草。这项工作旨在量化已建立的马tana丹生物防治剂套件对南非大陆性内陆地区内地条件下植物生长的综合影响。采用杀虫排斥法比较了排斥植物和生物防治植物之间的植物生长参数和药剂破坏。尽管无法维持完全没有生物防治剂的排斥植物，但与排斥植物相比，在生物防治中，叶片损伤增加了44％，侧茎产量降低了16％。在研究期间，叶片损伤与侧茎产量减少之间存在正相关关系。总体而言，杀虫剂排斥虽然仅部分有效，
