The potential abilities of 3-methylbenzaldehyde derived from Myosotis arvensis oil and its structural analogues to act as new acaricide and mite kit (mite color deformation) against Tyrophagus putrescentiae (Schrank) were evaluated in the present study. Based on the LD values, 2,4,5-trimethylbenzaldehyde (0.78 μg/cm) had highest vapor action against T. putrescentiae, followed by 2,4-methylbenzaldehyde (1.14 μg/cm), 2,5-dimethylbenzaldehyde (1.29 μg/cm), 2-methylbenzaldehyde (1.32 μg/cm), 2,3-dimethylbenzaldehyde (1.55 μg/cm), 3-methylbenzaldehyde (1.97 μg/cm), and 4-methylbenzaldehyde (2.34 μg/cm). The color deformation of seven methylbenzaldehyde analogues mixed with 2,3-dihydroxybenzaldehyde against T. putrescentiae showed mite color deformation, from coloress to reddish brown, and valuable to distinguish with the naked eye. In addition, there was no antagonistic interactions between 2,3-dihydroxybenzaldehyde and the methylbenzaldehyde analogues. These finding suggests that the methylbenzaldehyde analogues could be developed as dual functional agent to protect from fall in the commercial value of stored food products.
本研究评估了来自于勿忘草油及其结构类似物的 3-甲基苯甲醛在作为新型杀螨剂和杀螨剂 kit（螨体色变形）防治腐食酪螨（Schrank）方面的潜在能力。基于 LD 值，2,4,5-三甲基苯甲醛（0.78μg/cm）对腐食酪螨具有最高的蒸气作用，其次是 2,4-甲基苯甲醛（1.14μg/cm）、2,5-二甲基苯甲醛（1.29μg/cm）、2-甲基苯甲醛（1.32μg/cm）、2,3-二甲基苯甲醛（1.55μg/cm）、3-甲基苯甲醛（1.97μg/cm）和 4-甲基苯甲醛（2.34μg/cm）。七种甲基苯甲醛类似物与 2,3-二羟基苯甲醛混合对腐食酪螨的体色变形显示出螨体色变形，从无色变为红棕色，用肉眼即可有价值地区分。此外，2,3-二羟基苯甲醛与甲基苯甲醛类似物之间没有拮抗相互作用。这些发现表明，甲基苯甲醛类似物可以开发为双重功能剂，以防止储存食品商业价值下降。
