Stable fly (<Emphasis Type="Italic">Stomoxys calcitrans</Emphasis>) and house fly (<Emphasis Type="Italic">Musca domestica</Emphasis>) densities: a comparison of three monitoring methods on pig farms

House flies (Musca domestica L.) and stable flies (Stomoxys calcitrans [L.]) are important pests on livestock farms and often occur in mixed populations. In order to identify when control actions must be taken, monitoring is essential. The two fly species should be monitored independently as they affect animals differently and may also differ in their responses to control measures. Here, we assess three monitoring methods on pig farms with mixed population of stable and house flies for quantifying fly abundance: spot cards, sticky traps, and a visual index. We compared estimated values from the spot card and a visual index method, which did not discriminate between fly species, with the number of each species caught on the sticky traps. Our results indicate that stable flies contribute less than half of the spots on the spots cards, compared with house flies. Thus, to monitor house flies, use of spot cards could be justified if the number of stable flies is low. However, the contribution of stable flies and house flies to the visual index differed between sites. Whether the visual index or sticky traps best represent the true fly densities is unknown. However, until proved otherwise, the visual index should primarily be used when the two species are registered separately. Threshold values for house fly control, as defined using spot cards (Pennsylvania, USA) versus visual index (Denmark), were compared and found to differ. Although this might be due to differences in tolerance between the two locations, unequal use of monitoring methods and differences between farms is also possible and highlights the need for a common monitoring technique for house flies internationally.     

Durability of isocyanate resin adhesives for wood I: Thermal properties of isocyanate resin cured with water

The thermal properties of isocyanate (IC) resin cured with water were studied using dynamic mechanical analysis (DMA) and Fourier transform infrared spectroscopy. The thermal properties of cured phenol formaldehyde (PF) resin were also studied for comparison purposes. The DMA specimens were prepared using a unique technique. The relation between the mechanical and chemical changes of the resin during DMA was clarified. The cured PF resin had better thermal stability than the IC resin cured with water. The improvement of thermal stability in cured IC resin by heat treatment was considered to be less effective. The effect of the heating rate on the mechanical properties was also investigated. The apparent activation energy in the thermal degradation of cured IC resin was calculated based on the results obtained.Part of this paper was presented at the 47th Annual Meeting of the Japan Wood Research Society, Kochi, April 1997

Amoebicidal and giardicidal compounds from the leaves of Zanthoxylum liebmannianun

The crude ethanol extract from the leaves of Zanthoxylum liebmannianum exhibited inhibitory effect on the reproduction of trophozoites of Entamoeba histolytica (IC(50)=3.48 microg/ml) and Giardia lamblia (IC(50)=58.00 microg/ml). From this extract, asarinin, hyperin, beta-sitosterol, and beta-sitosterol glucoside were isolated. Among them, asarinin was the most active with IC(50) values of 19.86 microg/ml for E. histolytica and 35.45 microg/ml for G. lamblia. The remaining compounds showed moderate activity against both parasites.     

Cytotoxic constituents from Plumbago zeylanica

Compound 1 showed cytotoxic activity against MCF7 and Bowes cancer cell lines (IC50 113 microM and 152 microM, respectively), beta-sitosterol inhibited Bowes cell growth (IC50 36.5 microM) and plumbagin was cytotoxic against MCF7 and Bowes cells (IC50 1.28 microM and 1.39 microM, respectively).     

3,5-Dicaffeoylquinic acid isolated from Artemisia argyi and its ester derivatives exert anti-Leucyl-tRNA synthetase of Giardia lamblia (GlLeuRS) and potential anti-giardial effects

An aqueous ethanol extract of Artemisia argyi inhibited the aminoacylation activity of LeuRS from Giardia lamblia (GlLeuRS). The bioassay-guided fractionation of the extract led to the isolation of 3,5-dicaffeoylquinic acid (1), with an IC(50) of 5.82μg/mL. The ester derivatives of 1 were also found to possess strong anti-GlLeuRS effects, with IC(50) values of 1.79, 5.51 and 2.56μg/mL respectively. Anti-giardial assay showed that the derivatives, especially 3,5-dicaffeoylquinic acid propyl ester (4) (IC(50)=4.62μg/mL), were effective at killing G. lamblia.
