双带夜蛾生物学及防治

双带夜蛾是水稻常见的害虫之一．在湖北省一年发生5代．以第五代幼虫化蛹越冬,每年5至9月为发生为害期．有世代重叠现象．本记述了该虫的生活年史,发育历期,生活习性．稻田种群数量消长,发生与环境的关系及天敌情况,提出了防治建议．     

铜色长角沼蝇的习性和生活史的初步观察（双翅目：沼蝇科）

长角沼蝇属幼虫可捕食鸭血吸虫(毛毕吸虫属)的中间宿主椎实螺。鸭血吸虫的尾蚴也可导致人的稻田皮炎;另一方面．长角沼蝇属的卵又是稻螟赤眼蜂(稻田螟虫卵的天敌)天然的交替寄主：因此长角沼蝇对卫生和农业都是有益的．本初步观察了华东地区一种常见的长角沼蝇——铜色长角沼蝇的成蝇形态特征、活动场所．出现季节,螺类宿主、幼虫食性和生活史．成虫寿命在春季为2个月。夏季为40-50天,一卵块通常含20-30个卵;幼虫以活椎实螺饲养．幼虫是否能攻击活的椎实螺,视幼虫期和宿主螺大小有关;自卵产下发育到羽化为成虫,平均温度在26℃时约需20天,在32℃时约为13天。

Pyrrhopterus (Latham), Ecuador, Peru; P. sanctithomae sp.n. from B. sanctithomae (Müller), Bolivia, Peru; P. tiricae sp.n. from B. tirica (Gmelin), Brazil; P. versicolori sp.n. from B. versicolorus (Müller), Brazil, Peru. From Touit: P. hemiphyllus (Mégnin & Trouessart) comb.n. [ =Pterolichus (P.) hemiphyllus ] from Touit batavica (Boddaert), Surinam, Trinidad; P. dilectissimae sp.n. thrn T. dilectissima (Sclater & Salvin), Colmbia, Costa Rica; P. huetii sp.n. from T. huetii (Temminck), Brazil, Guyana, Peru; P. parpuratae sp.n. from T. purpurata (Gmelin), Brazil, Guyana, Surinam; P. surdae sp.n. from T. surda (Kuhl), Brazil.

Pseudangularia gonzalezi n. sp. and Gibsonilepis swifti (Singh, 1952) n. g., n. comb. (Cestoda, Dilepididae) from the House Swift, Apus affinis (J.E. Gray) (Aves, Apodiformes) from Franceville, Republic of Gabon

Nine specimens of Apus affinis (J.E. Gray) were studied at Franceville, Haut-Ogooué Province, Republic of Gabon, for the presence of helminth parasites. Two cestode species of the family Dilepididae were recorded. Pseudangularia gonzalezi n. sp. is distinguished from the most similar species P. europaea Georgiev & Murai, 1993 by having elliptical cirrus-sac, longer vagina, longer rostellar sheath and greater diameter of suckers. An identification key to the species of the genus Pseudangularia Burt, 1938 is proposed. The present study is the first record of the genus Pseudangularia in the Afrotropical Region. Our study confirms that, in dilepidids with vaginal sclerites from swifts, breaking off the cirrus after copulation is a frequent phenomenon. The genus Gibsonilepis n. g. is erected as monotypic for Vitta swifti Singh, 1952 (originally described from the same host species in India) and Gibsonilepis swifti n. comb. is proposed. Gibsonilepis n. g. is distinguished from Vitta Burt, 1938 by its highly elongate rostellum, rostellar sheath much bigger than rostellum, relatively small rostellar hooks possessing strongly developed guard, disc-shaped suckers with weak peripheral musculature and flat or convex central part, long and well-expressed neck, highly lobed two-winged ovary (lobes rounded) and presence of a band consisting of rows of spine-like microtriches along posterior margin of each proglottis. This is the first record of G. swifti in the Afrotropical Region. The separation of G. swifti from the genus Vitta (parasites of swallows) suggests that, contrary to previous opinions, no dilepidid genera are shared by Apodidae (swifts) and Hirundinidae (swallows).     

Feinstruktur der Leberzellen vonOxidus gracilis (C.L. Koch, 1847) (Diplopoda,Paradoxosomatidae)

Zusammenfassung Bei den Vertretern einiger Diplopoden-Familien ist der Mitteldarm von einer zelligen Hüllschicht umgeben. Die Perikaryen stehen dicht bei dicht, basale Ausläufer durchziehen die Fasern der Muskularis und verzweigen sich sekundär beim Eintritt in die sehr dicke Basallamina des Mitteldarmepithels. Die terminalen Endigungen jeder Zelle dringen in ein extrazelluläres basales Labyrinth je einer ausdifferenzierten Mitteldarmzelle ein und verflechten so die Hüllschicht mit dem Darmepithel. Darüberhinaus scheint es Fusome zwischen den Endaufzweigungen und der Mitteldarmzelle und damit die Möglichkeit eines intrazellulären Stofftransports zwischen beiden Zellen zu geben.Die Hüllschicht ist kein Epithel, denn Zellkontakte zwischen benachbarten Zellen fehlen ebenso wie eine gemeinsame Basallamina. jede Zelle ist von ihrer eigenen, dünnen Basallamina umgeben. Sie wird außerdem bei normal ernährten Individuen durch einen großen Vorrat an Glykogen und zahlreiche Zytosomen charakterisiert. Viele Mitochondrien sind dadurch vor allem in die Zellperipherie oder in die basalen Ausläufer gedrängt. In deren Nähe findet man auch überwiegend glattes endoplasmatisches Retikulum, und auch freie Ribosomen sind nicht selten. Der Zellkern vermittelt den Eindruck hoher Stoffwechselaktivität; ein Nukleolus ist immer vorhanden. Mikrotubuli sind im Zellkortex parallel zur Oberfläche orientiert, vor allem aber in den basalen Ausläufern in Längsrichtung. Obwohl kein Fett gespeichert wird, kann man die Zellen mit dem Chloragog-Gewebe der Anneliden oder mit den Leberzellen der Vertebraten vergleichen. Sie scheinen von den Mitteldarmzellen Nährstoffe zu übernehmen, diese zu verarbeiten, die Produkte freizusetzen oder zu speichern und dabei wertlose stickstoffhaltige Moleküle in den Zytosomen abzulagern. Der gebräuchliche Terminus Leberzellen ist daher angebracht.Tiere, die 14 Tage ohne Nahrung gehalten wurden, zeigen eine erhebliche Schrumpfung der Leberzellen. Deren Plasmalemm ist nur an einigen Stellen mit der Basallamina verbunden, überall sonst ist der extrazelluläre Raum zwischen Zellmembran und Basallamina stark erweitert. Das Glykogen ist größtenteils abgebaut. Der elektronenoptische Kontrast der verschiedenen Zellelemente ist äußerst schwach. Die Mikrotubuli sind völlig verschwunden. Nur die Zytosomen heben sich weiterhin deutlich ab. Aber auch sie scheinen umgewandelt und zu wenigen Ansammlungen zusammengeflossen zu sein. Dies deutet auf Mobilisierung des gespeicherten Glykogens hin, kann aber auch beginnende Degeneration der Leberzellen signalisieren.

Fine structure of the liver cells ofOxidus gracilis (C.L. Koch, 1847) (Diplopoda, Paradoxosomatidae)

Summary In some families of Diplopods the midgut is surrounded by an enveloping cell layer. Basal runners of their pericarya get through the longitudinal and transversal muscle fibres and ramify secundarily before entering the very thick basement membrane of the midgut epithelium. The terminal branches of each cell enter into a basal labyrinth of only one differentiated midgut cell interlacing intensively with the epithelium in this way. Moreover it seems that there are open junctions (fursomes) between terminal branches and the midgut cell and therefore an intracellular transport of materials.The enveloping layer is no epithelium. THere are no typical contacts between neighbouring cells; each enveloping cell is surrounded by its own thin basement membrane, a common basement membrane does not exist. Enveloping cells of normally nourished individuals are characterized by a large storage of glycogene in the cytoplasm. Besides this there are many distinct cytosomes which point at a significant activity in metabolism. Many mitochondria, which mostly pushed off towards the cell periphery or lie in the primarily ramifications indicate the same. Close by there is also prevailing smooth endoplasmic reticulum. Free ribosomes are not rare. The nucleus gives the impression of activity in metabolism too; a nucleolus does exist. Microtubules arranged parallely to the cell surface in the cortex, but especially in the basal ramifications in longitudinal direction can be seen. Though lipoids are not being stored, one might compare these cells with the chloragog tissue in annelids or with the liver cells in vertebrates. They seem to accept food from the midgut cells, to digest and release, respectively store it temporarily, depositing at that valueless nitrogene containing molecules into the cytosomes. The usual term liver cell therefore is wellchosen.Animals after 14 days without food signify a large shrinkage of the liver cells. Plasmalemma is fixed only at certain points to the basement membrane; the extracellular space between them is widened extremely. Glycogene mostly is removed. The electron microscopically visible contrast of the cell elements is very faint. Microtubules have disappeared. Cytosomes, however, contrast distinctly. But they, too, seem to be transformed and joined into a few accumulations. This points to mobilization of the stored glycogene, but in the same manner also to symptomes of degeneration brought into action.
