Clay preference and particle transport behavior of Formosan subterranean termites （Isoptera： Rhinotermitidae）＂ A laboratory study

引用

Insect Science 2014年第6期21卷 785-795页

作者： Cai Wang Gregg henderson department of Entomology Louisiana State University Agricultural Center Baton Rouge LA 70803 USA

Although preference and utilization of clay have been studied in many higher termites, little attention has been paid to lower termites, especially subterranean termites. The Formosan subterranean termite, Coptotermes formosanus Shiraki, can modify its habitat by using clay to fill tree cavities. Here, the biological significance of clay on C. formosanus was investigated. Choice tests showed that significantly more termites aggre- gated in chambers where clay blocks were provided, regardless of colony group, observation period, or nutritional condition （fed or starved）. No-choice tests showed that clay had no observable effect on survivorship, live or dry biomass, water content, and tunneling activity after 33-35 d. However, clay appeared to significantly decrease filter paper consumption （dry weight loss）. Active particle （sand, paper, and clay） transport behavior was observed in both choice and no-choice tests. When present, clay was preferentially spread on the substrate, attached to the smooth surfaces of the containers, and used to line sand tunnels. Mechanisms and potential application of clay attraction are discussed.

Catalytic Performance in CO Hydrogenation Over SiO_2-Supported Ru-M (M=Co, Fe,Mo,Ni,Rh,Mn and Cr) Bimetallic Cluster-derived Catalysts

The bimetallic Ru-M (M=Co,Fe,Ni,Mo, Rh,Cr, Mn) catalysts were prepared from SiO_2-supported bimetallic carbonyl clusters, and it was found that the Ru-Co, Ru-Fe and Ru-Mo bimetallic carbonyl cluster-derived catalysts showed higher activity and selectivity for oxygenates such as C_1-C_5 alcohols in CO hydrogenation,in contrast to catalysts prepared from SiO_2-supported homometallic Ru and Co carbonyl clusters. In situ FT-IR studies revealed that the bands at 1584 and 1555 cm^(-1) species were intermediates to produce methanol and higher oxygenates,and at higher temperatures the 1584 cm^(-1) species could react with alkyl to form 1555 cm^(-1) species. By the surface chemical reaction and the IR study of isotopic molecules,it was suggested that 1584 and 1555 cm^(-1) were assigned to surface formyl and acetyl species.

Localized treatments using commercial dust and liquid formulations of fipronil against Coptotermes formosanus （Isoptera： Rhinotermitidae） in the laboratory

引用

Insect Science 2014年第2期21卷 174-180页

作者： Bal K. Gautam Gregg henderson Cai Wang department of Entomology Louisiana State University LA 70803 USA

Use of proper application methods and formulations of termiticides are im- portant to reduce their negative impact to the environment. In this study, we conducted laboratory experiments to determine the effect of localized treatments with commercial dust and liquid formulations of fipronil against Formosan subterranean termites, Coptoter- mes formosanus Shiraki. The test arena consisted of a specially designed 16-chambered structure with a center chamber connected to 5 foraging chambers that themselves were connected to 10 additional foraging chambers. One peripheral chamber received a liquid or dust treatment and termites were released in the center chamber. Results showed that 〉 91% of the termites were dead within the 9-d test period despite the localized treatment of only 1 foraging chamber. Termites that were still alive after 9 d were transferred to an untreated dish and held for 10 more days. The majority of those termites were dead and the rest were moribund on day 19. Regardless of the specific dish treated, both formulations of fipronil were found to be highly efficacious. Termites did not exhibit repellency to either formulation. Our results suggest that localized （or spot） treatment with either commer- cially available dust or liquid formulations of fipronil can be a viable option for control of a termite infestation where complete soil drenching is not desirable.

Cocoon samples were collected from fifty-two mulberry gardens with high, intermediate, and low silkworm cocoon productivities in the lower-middle reaches of the Yangtze River in the six China’s provinces of Jiangsu, Jiangxi, Anhui, Fujian, Hunan, and Hubei to determine the transformation efficiency of S from mulberry leaves to silkworm cocoons, and to evaluate the sulfur cycle (uptake and output) in the mulberry leaf-silkworm cocoon system with typical mulberry gardens in the lower-middle reaches of the Yangtze River in China. The transformation efficiency of sulfur (TES) from mulberry leaves into silkworm cocoons in the high-productivity mulberry gardens was significantly lower (P ductivity gardens. For the high-productivity mulberry gardens the TES from mulberry leaves into the cocoon shells was significantly higher (P d mulberry gardens. Producing 1 kg dry cocoon in mulberry gardens required uptake of about 20 g S, however 1 kg of dry cocoon only removed about 4 g S. Therefore, recycling of these organic wastes with silkworm cultivation was important for sulfur balances.

Regional Moisture Source Changes Inferred from Late Holocene Stable Isotope Records

引用

Advances in Atmospheric Sciences 2008年第6期25卷 1021-1028页

作者： Zhonghui LIU Andrew C. G. henderson Yongsong HUANG department of Geological Sciences Brown University Providence RI 02912 USA Environmental Change Research Centre Department of Geography University College London 26 Bedford Way London WCIH OAP UK

Qinghai Lake, China, is located near the northern limit of the East Asian summer monsoon （EASM） and thus is an ideal region for studies of past monsoonal changes. However, isotope records from this region reflect the combined effects of multiple climatic factors, and make climatic interpretations difficult. The authors use multi-proxy records, generated from the same sediment core from Qinghai Lake, to disentangle these multiple effects in isotope records and to infer EASM variability during the late Holocene. Records of leaf wax （C2s） δd, lake carbonate 5180 and the dunde ice core δ18O all indicate a millennial-scale depletion of mean isotopic values at -1500-1250 years before present. Compared with independent lake temperature and salinity records, the authors suggest that this depletion of long-term mean isotopic values must have resulted from changes in moisture sources in this region. In contrast, the authors attribute high-frequency （centennial timescale） C2s δd and ice core δ18O variability dominantly to a temperature effect. The multiproxy records provide a coherent picture in that many aspects of this regional climate （temperature, dryness, and moisture source） are strongly linked to the EASM variability.

Cremaster muscle thickening: the anatomic difference in men with testicular retraction due to hyperactive cremaster muscle reflex

引用

Asian Journal of Andrology 2023年第4期25卷 484-486页

作者： Parviz K Kavoussi Hayden T henderson Kayla Hudson Romtin Mehrabani-Farsi Graham Luke Machen Austin Fertility and Reproductive Medicine/Westlake IVF AustinTX 78746USA

The objective was to assess whether men suffering from testicular retraction secondary to hyperactive cremaster muscle reflex havean anatomic difference in the thickness of the cremaster muscle in comparison to men who do not have retraction. From March2021 to december 2021, 21 men underwent microsurgical subinguinal cremaster muscle release (MSCMR) on 33 spermatic cordunits, as 12 of them had bilateral surgery, at Surgicare of South Austin Ambulatory Surgery Center in Austin, TX, USA. duringthat same time frame, 36 men underwent subinguinal microsurgical varicocele repair on 41 spermatic cord units, as 5 werebilateral for infertility. The thickness of cremaster muscles was measured by the operating surgeon in men undergoing MSCMRand varicocele repair. Comparison was made between the cremaster muscle thickness in men with testicular retraction due toa hyperactive cremaster muscle reflex undergoing MSCMR and the cremaster muscle thickness in men undergoing varicocelerepair for infertility with no history of testicular retraction, which served as an anatomic control. The mean cremaster musclethickness in men who underwent MSCMR was significantly greater than those undergoing varicocele repair for infertility, witha mean cremaster muscle thickness of 3.9 (standard deviation [s.d.]: 1.2) mm vs 1.0 (s.d.: 0.4) mm, respectively. Men withtesticular retraction secondary to a hyperactive cremaster muscle reflex demonstrate thicker cremaster muscles than controls,those undergoing varicocele repair. An anatomic difference may be a beginning to understanding the pathology in men whostruggle with testicular retraction.
