Study of potential activity of clove oil 10 % emulsifiable concentrate formulation on Two-spotted spider Mite Tetranychus urticae Koch (Acari: Tetranychidae)

Clove oil is reported to have a great range of biological activities against many species of pests; termites, cockroaches, aphids, weevils and moths, and many different usages such as perfume and food flavoring agent. This study aimed to determine the acaricidal activity of clove oil emulsifiable concentrate new formulation against two-spotted spider mites Tetranychus urticae. Clove oil was formulated as 10 % emulsifiable concentrate (EC). The new formula passed successfully all physical and chemical tests reported for emulsifiable concentrates. It was then tested biologically on the individuals of two-spotted spider mite T. urticae Koch (Acari: Tetranychidae) on two host plants beans and squash under laboratory conditions. In both cases, there were a direct relationship between the increase in the concentration of the formulation and the percentage of inhibition on the individuals of the two-spotted spider mite, after 72 hours of treatment, at concentrations of 20, 40, and 80 mg/ml the new formulation showed 10.30, 44.8, and 75 percent inhibition, respectively in case of beans, while squash at the same concentrations and for the same period of treatment showed 33.3, 40.7, and 51.9 percent inhibition, but the effect in case of beans was greater than that in case of squash as its EC50 value was lower than that in case of squash. In the case of the former, it was 39.81 mg/ml, whereas in the case of the latter, it was 79.43 mg/ml. Therefore, the new clove oil formulation can be used to combat the two-spotted spider mite.

Harnessing Acremonium zonatum (Sawada) Gams oil formulations as water hyacinth control mycoherbicides.

The effect of formulating Acremonium zonatum (Saw.) Gams in corn oil, mineral oil and glycerol was determined in a glasshouse at Maseno University Botanic Garden and laboratory. The study was situated at latitude -100’ 00’’ S and longitude 340 36’ 00’’E. A. zonatum was aseptically isolated from symptomatic plants and inoculated upon healthy water hyacinth plants in a CRD experiment. Data was analyzed using SPSS version 20 computer software. Oil and spore density effects were statistically significant at p < 0.05. The main effect of oil yielded an effect size of 0.281 indicating that 28.1 % of the variance in disease severity was explained by the oil formulation (F(2, 28) = 5.459, p = 0.01). Spore density yielded an effect size of 0.326 indicating that 32.6% of the variance in the study was explained by spore density (F(3, 28) = 4.515, p = 0.011). The interaction effect was not significant (F(6, 28) = 0.199, p = 0.974) indicating that there was no combined effect for the kind of oil used in the formulation of the A. zonatum and the spore density. The results suggested that A. zonatum pathogenicity varies with different spore concentrations, 1x 108 spores/ml being the most potent. A. zonatum has favorable characteristics for consideration as a mycoherbicide. Corn oil as formulation material was concluded to be the best formulation material for A. zonatum.

Susceptibility of Tuta absoluta (Lepidoptera: Gelechiidae) Pupae to Soil Applied Entomopathogenic Fungal Biopesticides

Management of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) in greenhouses and under open-field tomato cultivation relies on an integrated approach, largely targeting the egg and larval stages of the pest. However, little to no research has been done on the efficacy of EPFs for control of the pupal stage. The aims of this study were to determine the susceptibility of T. absoluta pupae to Beauveria bassiana and Metarhizium anisopliae spores applied as soil drench treatments, and the possible effects of these treatments on fecundity and fertility of moths. The lethal concentrations (LC50 and LC80) of the respective products were estimated in dose-response bioassays by exposing pupae in a soil substrate to different concentrations of EPF products. Emerging moths were paired in different combinations, according to EPF exposure treatments after which fecundity and fertility of females were recorded. Pupae in the soil were effectively controlled by all EPF products in both bioassays as well as in a growth tunnel experiment. The LC50 value of the B. bassiana oil formulation was significantly lower than that of other treatments. The fecundity of females that were subjected to the B. bassiana oil formulation was significantly lower than that of the control treatment. This study showed the potential of soil drench applications of both B. bassiana and M. anisopliae for control of T. absoluta pupae.

The beneficial effect of Cannabis Sativa seed oil on the epidermis

Background: Cannabis Sativa seed oil has become more and more popular in cosmetic industry mainly due to the high content of antioxidants and unsaturated fatty acids that are desirable in formulations because they prevent moisture loss and reduce the occurrence of dry skin. Objective: The aim of this study was to determine the effect of Cannabis Sativa seed oil on skin parameters such as hydration and transepidermal water loss. Methods: The in vivo tests on volunteers with combination skin were performed by using non-invasive methods by using corneometer and tewameter. Results: The obtained results proved that Cannabis Sativa seed oil improved skin condition. The transepidermal water loss decreased because the lipophilic components of the oil formulation tend to form an occlusive layer on the epidermis surface. The highest increase in skin hydration was observed after one week of treatment. Conclusion: These results confirmed that Cannabis Sativa seed oil has strong moisturizing properties and can be recommended as a natural based skin conditioning agent.
