摘要
为了明确新型无机铜制剂对柑橘全爪螨种群的影响,选用两种进口铜制剂,对比分析在不同施药浓度下,温州蜜桔上柑橘全爪螨若螨与成螨种群数量的动态变化。结果表明:分别用84%王铜水分散粒剂1500倍、750倍液和86%波尔多液水分散粒剂水分散粒剂750倍、500倍液处理2次后,随着处理时间的增加,温州蜜桔上柑橘全爪螨的成、若螨的种群数量有所上升,但在相同时间段,与CK相比,各处理间种群数量无显著差异,表明这两种新型铜制剂不会诱发红蜘蛛的发生。
In order to determine the effects of modern high-quality copper preparations on the population of Panonychus citri McGregor,two imported copper preparations were selected in this study to compare and analyze the dynamics of the populations of nymphal and adult mites in satsuma mandarin under different application concentrations.The results showed that the population of P.citri in satsuma mandarin was increased with the same concentration,after treatment with 84%copper oxychloride WDG diluted 1500 times and 750 times,86%Bordeaux liquid WDG diluted 750 times and 500 times.But compared with the CK,there was no significant difference for the population over the same period.It indicated that these two new copper preparations could not induce the occurrence of spider mites.
