The effects of 0.75 % concentration of cinnamon essential oil on bait attractiveness and total biological efficacy of bromadiolone and difenacoum rodenticides to the house mouse were tested in practice. The experiments were conducted in storages with stable house mouse populations for which no resistance to anticoagulant rodenticides had been previously reported. A statistically significant difference was detected between bromadiolone and difenacoum baits. Consumption of bromadiolone baits supplemented with cinnamon essential oil was 74 % higher than the consumption of bromadiolone baits without cinnamon oil. The average efficacy of bromadiolone baits in controlling house mice was 96 %. Cinnamon essential oil added to difenacoum baits increased bait consumption by 39 %, i.e. it was 119 % higher than the consumption of oil-free baits. The average efficacy of difenacoum baits in controlling house mice was 99.5 %.

The effect of cinnamon (Cinnamomi zeylanicum) and clove (Eugenia caryophyllata) essential oils on the acceptibility of cereal-based baits to house mice in storage facilities was examined. The effects of three concentrations, 0.5, 0.75 and 1 %, were tested for optimization purposes. The experiments were performed in a mill storage, and in another storage for seeds and seedlings. Attractiveness of the examined concentrations of cinnamon and clove essential oils was statistically significant, compared to placebo bait, within seven days of the experiment. On the seventh day, the average consumption of baits containing 0.75 % and 1 % concentrations of cinnamon oil was 46 % in the mill storage, i.e. 35.5 % more than placebo baits were consumed. Fourteen days after the beginning of the experiment, no significant difference was detected in the consumption of baits offered in the mill storage. On the other hand, a significant difference was revealed regarding the consumption of examined baits in the seed and seedling storage. The average consumption of baits containing 0.75 % and 1 % cinnamon oil was 47 % and 51 % higher after 14 days than the consumption of placebo bait. Compared to the other test baits, those containing cinnamon essential oil at 0.75 % and 1 % concentration demonstrated better attractiveness without mutual statistically significant differences.

SUMMARYThe efficacy of the newly developed anticoagulant rodenticide WBA 8119 was evaluated against the house mouse (Mus musculus L.) using individual and family groups of warfarin-resistant animals. WBA 8119 at 0·002 %, O % and 0.01 % in pinhead oatmeal bait gave complete kills of mice in ‘no-choice’ feeding tests carried out in cages and small pens. In replicated 21-day treatments on families of mice confined in larger pens and conditioned to feeding on plain foods, the overall mortalities obtained using the three formulated poison baits were 71/72, 62/63 and 57/57 respectively.The results of the WBA 8119 toxicity tests are considered in relation to previous findings on other anticoagulant rodenticides, particularly difenacoum. In equivalent tests, WBA 8119 performed better than difenacoum. The data thus support the laboratory findings that WBA 8119 is the most active anticoagulant so far tested for the control of warfarin-resistant house mice.

AbstractBackgroundHumans routinely attempt to manage pest rodent populations with anticoagulant rodenticides (ARs). We require information on resistance to ARs within rodent populations to have effective eradication programs that minimise exposure in non-target species. Mutations to the VKORC1 gene have been shown to confer resistance in rodents with high proportions of resistance in mice found in all European populations tested. We screened mutations in Mus musculus within Western Australia, by sampling populations from the capital city (Perth) and a remote island (Browse Island). These are the first Australian mouse populations screened for resistance using this method. Additionally, the mitochondrial D-loop of house mice was sequenced to explore population genetic structure, identify the origin of Western Australian mice, and to elucidate whether resistance was linked to certain haplotypes.ResultsNo resistance-related VKORC1 mutations were detected in either house mouse population. A genetic introgression in the intronic sequence of the VKORC1 gene of Browse Island house mouse was detected which is thought to have originated through hybridisation with the Algerian mouse (Mus spretus). Analysis of the mitochondrial D-loop reported two haplotypes in the house mouse population of Perth, and two haplotypes in the population of Browse Island.ConclusionsBoth house mouse populations exhibited no genetic resistance to ARs, in spite of free use of ARs in Western Australia. Therefore weaker anticoagulant rodenticides can be employed in pest control and eradication attempts, which will result in reduced negative impacts on non-target species. Biosecurity measures must be in place to avoid introduction of resistant house mice, and new house mouse subspecies to Western Australia.

Aspergillus flavus is a frequent contaminant of maize grain. We isolated this fungus, determined the colony morphology and species (by internal transcribed spacer sequencing) and measured the aflatoxin content. The selected A. flavus fungi were placed into two groups, toxigenic and atoxigenic; both appeared similar morphologically, except that the atoxigenic group lacked sclerotia. An essential oil fumigation test with clove and cinnamon oils as antifungal products was performed on fungal conidial discs and fungal colonies in Petri plates. Cinnamon oil at 2.5 to 5.0 μL/plate markedly inhibited the mycelial growth from conidial discs of both strains, whereas clove oil showed less activity. The oils had different effects on fungal mycelia. The higher clove fumigation doses of 10.0 to 20.0 μL/plate controlled fungal growth, while cinnamon oil caused less inhibition. Compared with atoxigenic groups, toxigenic A. flavus responded stably. Within abnormal A. flavus hyphae, the essential oils degenerated the hyphal morphology, resulting in exfoliated flakes and shrinkage, which were related to fungal membrane injury and collapse of vacuoles and phialide. The treatments, especially those with cinnamon oil, increased the electroconductivity, which suggested a weak mycelium membrane structure. Moreover, the treatments with essential oils reduced the ergosterol content in mycelia and the aflatoxin accumulation in the culture broth. The fumigations with clove and cinnamon oils inhibited the development of both conidia and colonies of A. flavus in dose-dependent manners.

The house mouse, Mus musculus, was established in the early 1900s as one of the first genetic model organisms owing to its short generation time, comparatively large litters, ease of husbandry, and visible phenotypic variants. For these reasons and because they are mammals, house mice are well suited to serve as models for human phenotypes and disease. House mice in the wild consist of at least three distinct subspecies and harbor extensive genetic and phenotypic variation both within and between these subspecies. Wild mice have been used to study a wide range of biological processes, including immunity, cancer, male sterility, adaptive evolution, and non-Mendelian inheritance. Despite the extensive variation that exists among wild mice, classical laboratory strains are derived from a limited set of founders and thus contain only a small subset of this variation. Continued efforts to study wild house mice and to create new inbred strains from wild populations have the potential to strengthen house mice as a model system.

<p>This experiment was performed to investigate the effects of some essential oils on chemical properties and aerobic stability of lucerne silage. Treatments included lucerne silage without additives (control), lucerne silage with 60 mg cinnamon essential oil/kg, lucerne silage with 60 mg flaxseed essential oil/kg, lucerne silage with 60 mg lemon seed essential oil/kg, lucerne silage with 180 mg blend of essential oils (60 mg cinnamon + 60 mg flaxseed + 60 mg lemon seed essential oils/kg).<strong> </strong>Adding essential oils to lucerne silage reduced silage pH (<em>p </em>&lt; 0.001) compared to control. The highest level of total volatile fatty acids (tVFA) was found when lemon seed essential oil and the lowest level when flaxseed essential oil was used. The lucerne silages treated with essential oils had the highest crude protein contents (<em>p </em>&lt; 0.01). Untreated lucerne silage had the highest level of gas production compared to lucerne silage treated with lemon seed and flaxseed essential oils (<em>p </em>&lt; 0.01). The essential oil additives increased the aerobic stability of the silage. It can be concluded that the use of essential oil additive in the preparation of high quality lucerne silage, can improves the quality and nutritive value of silages.</p>

AbstractEmulsion is an efficient encapsulation tool for enhancing the functional properties of essential oils (EOs). Herein, two two-dimensional cinnamon essential oil emulsions (from micro- to nanoscales) were emulsified by hydroxypropyl methylcellulose, and their antimicrobial and physicochemical properties were investigated. For the models of Escherichia coli CGMCC 1.0907, Salmonella enterica subsp. Enterica serovar Typhi (CICC 10867), Staphylococcus aureus CGMCC 1.0089, and Listeria monocytogene CGMCC 1.9144, the minimum inhibitory concentration (MIC) of the nanoemulsion was 31.25 μL/mL compared to that of the microemulsion (62.5–125 μL/mL) and pure oil (125–250 μL/mL), indicating the superiority of nanoemulsion as an antibacterial agent. The results showed that the highest activity was seen in the gram-positive L. monocytogenes whereas the lowest was in the gram-negative S. enterica. The identified properties of HPMC (hydroxypropyl methylcellulose) provide the potential for emulsifying and enhancing essential oils in light industries, especially for food processing.

AbstractBackgroundAnxiety is the most common psychological reaction in women during labor. Similar to numerous other surgeries, postoperative pain is also reported following cesarean section (C-section). According to the (Gate) Control Theory, there is a relationship between pain and psychological problems such as anxiety. Accordingly, the present study aimed to compare the effect of aromatherapy using lavender and Damask rose essential oils on the level of anxiety and severity of pain following C-section.MethodsThis triple-group randomized clinical trial was performed on 90 mothers who visited Motahari Hospital of Jahrom, Iran, for C-section in 2017. The incidence and severity of pain and anxiety were measured and recorded for all three groups prior to intervention. The intervention groups underwent aromatherapy with lavender and Damask rose essential oils. Patients were asked to inhale cotton balls, separately stained with three drops of each essential oil at a distance of 10 cm for 30 mins. The severity of pain and anxiety was measured using the visual analogue scale (VAS) and the Spielberger State-Trait Anxiety Inventory (STAI) 5 min after the specified process, respectively. The control group underwent aromatherapy in a similar fashion with normal saline. Finally, data were analyzed using descriptive statistical indices and ANOVA and Kruskal–Wallis tests in SPSS 21.ResultsThere was no significant difference between the three groups in the mean severity of pain and anxiety before the intervention (p>0.05). The mean severity of pain and overt anxiety in the lavender and Damask rose aromatherapy groups was significantly different than the control group after the intervention (p<0.001). In addition, no significant difference was observed between the overt and overall anxiety levels of the two intervention groups after the intervention (p>0.05).ConclusionsThe findings suggested that inhalation aromatherapy can reduce the severity of overt anxiety and pain after C-section, with Damask rose essential oil showing a larger effect than lavender.

SummaryA combination of calciferol (vitamin D2) and warfarin, each at 0·025% in medium oatmeal bait, failed to control six of seven house-mouse (Mus musculus L.) populations infesting urban and farm buildings. In three further treatments with both calciferol and warfarin at 0·05 % in dehusked canary seed bait plus 5% corn oil, mortality, estimated from the consumption of pre- and post-treatment census bait, ranged between 94·2 and 97·4%. Finally, among sixteen treatments done with calciferol at 0·1% and warfarin at 0·025% in various cereal baits, the best results (97·0–100%) were obtained in six treatments where the bait-base was whole canary seed; this was so whether the poison bait was applied directly or after a 3-day pre-baiting period. It is concluded that calciferol at 0·1 % plus warfarin at 0·025 % is an effective combination against house-mice, especially when used with whole canary seed. The role played by warfarin in the poison mixture needs to be investigated further.
