Abstract

Fumigation has been the most convenient method in the field of pest control in museums. In this study, as fumigants, ethanol 70%, deltamethrin (commercial pesticide (CP) ) , essential oil (EO) from Pinus regida, and low oxygen microenvironment (0.1%, (LOM) ) were tested individually and jointly against museum fungal strain Alternaria alternata. Three concentrations of each CP and EO were chosen for evaluating the individual effect. In the joint action fumigation process, three lower concentrations of CP and EO were tested in LOM. The rate of mycelial growth inhibition at each fumigation process was determined by two steps: 1) directly after the fumigation process and 2) after 7 d of the inoculation of the fumigated spores in new medium and incubating it in normal condition. The results demonstrated that applying of each chemical (CP or EO) in LOM enhanced its fungicidal activity and that effect of EO improved from fungistatic to fungicidal by jointing with LOM.

精油、商品杀菌剂和低氧微环境对博物馆霉的熏蒸作用新认识。

熏蒸是目前博物馆病虫害防治中最简便的方法。以70%乙醇、溴氰菊酯(商用农药)、红松精油(EO)和低氧微环境(0.1%，LOM)作为熏蒸剂，分别和联合对博物馆真菌交替孢霉(Alternaria alternata)进行了抑菌试验。分别选择三种浓度的CP和EO来评估个体效应。在联合熏蒸过程中，在LOM中检测了三种较低浓度的CP和EO。每个熏蒸过程中菌丝生长抑制率的测定分为两个步骤:1)直接熏蒸后，2)在新培养基中接种熏蒸后的孢子，并在正常条件下培养7 d后。结果表明，各化学物质(CP或EO)在LOM中的施用均增强了LOM的杀真菌活性，EO与LOM的结合使其抑菌作用向杀真菌作用转变。
