Pterygodermaties (Mesopectines) nycticebi (M?nnig, 1920) (Nematoda: Spirurida: Rictulariidae) is redescribed based on immature and mature adults collected from the stomach and small intestine at autopsy of a slow loris, Nycticebus coucang (Boddaert, 1785) (Mammalia: Primates), in a zoological garden in Japan. It is first demonstrated that male possesses a minute telamon and a left lateral pore in the preanal part of body. The cause of death of the slow loris is strongly surmised to be related to the nematode infection, which was apparently acquired under captivity in the zoological garden. 相似文献

在中国的赤眼蜂属(庞雄飞和陈泰鲁,1974,1978)中记述了分布于我国的12种赤眼蜂,其中个别种的学名仍有争议。此外,在过去的一些资料中曾记述过其他种名。不少读者来信询及这些问题,我们在这里提出简单的讨论。 1.螟黄赤眼蜂Trichogramma chilonis Ishii Flanders et Guednau(1960)把该种列入稻螟赤眼蜂T.japonicum Ashmead的异名,Doutt et Viggiani(1968)也没有列入该种。我们认为,把该种列为稻螟赤眼蜂T.japonicum Ashmead的异名不一定恰当。Ishii(1941)在首次描述该种时,曾在附图中把这两种的雄性外生殖器特征作了比较,看来,螟黄赤眼蜂T.chilonis Ishii的雄性外生殖器比较特殊,应为独立的种。在Ishii的原描述中,记录了该种首次采于菲律 相似文献

Plant extracts (botanicals) are of special significance for plant protection, especially in organic farming. This is due to their origin, specific modes of action, toxicological and ecotoxicological properties as well as to ever changing legal, patent, economic and social/political issues. This paper surveys this complex background and presents data on two selected botanicals which pertain to the use of extract fractions from Glycyrrhiza glabra (sweet wood) for control of Bremia lactucae (downy mildew) in lettuce and azadirachtin for control of leafhoppers in Melissa officinalis L. Both compounds exhibited good effects in the greenhouse which were less pronounced or absent in the field. The effects of sweet wood were strongest when applied twice preventively at 5?% concentration. In the greenhouse, this resulted in a lower number of infected plants and smaller leaf areas attacked by the downy mildew pathogen at high disease pressure. Azadirachtin (plant protection chemical NeemAzal®-T/S in combination with the additive Trifolio S-forte; 1.5 l/ha + 3 l/ha in 600 l water per hektar, 3 applications, interval 7 days) was better in controlling leaf hoppers than natural pyrethrins in combination with rapeseed oil (Spruzit Schädlingsfrei; 6 l/ha in 1,000 l water per hektar, 1 application) in the greenhouse and exhibited very high insecticidal efficacy almost equivalent to that of thiacloprid (Calypso 480 SC; 0.12 l/ha in 400 l water per hektar, 1 application) at moderate disease pressure. Thiacloprid, however, is not applicable in organic farming. In order to introduce these promising results in practical plant protection further fundamental studies are needed. These can only be realized by a joint effort of private companies, research and plant protection institutions, as well as public funding bodies. This article is not meant as a presentation of “perfect” results, it is rather an example of the problems and pitfalls that need to be overcome during development of a botanical and its applications. They are the reason why the market for botanicals will remain small. 相似文献

Fusarium head blight (scab) epidemics of wheat occurred in uawy (Northern Poland) during 1998 and in Wielkopolska (West) and in Southern regions of Poland in 1999. Four species were identified in wheat heads with scab symptoms: Fusarium culmorum, Fusarium graminearum, Fusarium avenaceum and Microdochium nivale. A significant increase in the frequency of F. graminearum (between 23% and 38%), was observed, compared to about 10% during the previous decade. The mycotoxins deoxynivalenol (DON), nivalenol (NIV) and moniliformin (MON) in amounts up to 24.3, 14.2 and 1.72mgkg–1respectively, were identified in kernels samples. 相似文献
