Monoterpenoids and low pressure have each been demonstrated to cause mortality of stored-product insect pests. The current report investigated the prospects of integrating the two methods in the management of diapausing and nondiapausing larvae of Plodia interpunctella (Hübner). In a separate experiment, the larvae were exposed to 35.5 mmHg in Erlenmeyer flasks at 19 and 28 degrees C for times ...

Terpenes and terpenoids encompass one of the most extensive valuable classes secondary metabolites. Their ten-carbon-containing oxygenated representatives, monoterpenoids, are main components plant essential oils, being widely exploited in cosmetic, pharmaceutical, food industrial areas. Due to its widespread use, it is crucial investigate their environmental distribution. Thus, new water solub...

The aim of the work was to obtain essential oil from leaves and flowers genus Hawthorn Crataegus monogyna L. study its component composition justify possibility expanding use this herbal drugs in medicine.
 Materials methods. Сrataegus L., which were used oil, harvested western region Ukraine 2019. quantitative content determined by hydrodistillation. By chromato-mass spectrometry method o...

We evaluated the acute toxicities and the physiological effects of plant monoterpenoids (eugenol, pulegone, citronellal and alpha-terpineol) and neuroactive insecticides (malathion, dieldrin and RH3421) on flight muscle impulses (FMI) and wing beat signals (WBS) of the blow fly (Phaenicia sericata). Topically-applied eugenol, pulegone, citronellal, and alpha-terpineol produced neurotoxic sympto...

Abstract Cyanobacteria are characterized by a very high tolerance to environmental factors. They found in salt water, fresh thermal springs, and Antarctic waters. The wide spectrum of habitats suitable for those microorganisms is related their particularly effective metabolism; resistance extreme conditions; the need only limited resources such as carbon dioxide, simple inorganic salts, light. ...

Bioassays were conducted to study the effectiveness of selected chemicals to prevent the multicolored Asian lady beetle, Harmonia axyridis (Pallas), from overwintering in buildings. We discovered that certain monoterpenoids elicited avoidance in adults toward treated Þlter paper within a petri dish bioassay at 1.0 mg/cm. Camphor and menthol were the most effective of the monoterpenoids tested. ...
