Immunocytochemical localization of the Bacillus sphaericus binary toxin components in Culex quinquefasciatus (Diptera: Culicidae) larvae midgut

This study describes the immunocytochemical localization of the Bacillus sphaericus 2362 binary toxin components, BinA and BinB, in Culex quinquefasciatus larvae that had been intoxicated with this entomopathogen. Ultrathin sections of C. quinquefasciatus larvae midgut embedded in the hydrophilic resin L.R. White were incubated with the antibodies anti-BinA or anti-BinB and then revealed with goat anti-rabbit IgG coupled to gold particles. Immunocytochemical detection demonstrated the presence of specific labeling in ultra-thin sections that had been incubated with the BinA antiserum. Gold particles were detected on the apical areas of cell membranes and inside the epithelial cell cytoplasm, particularly the mitochondria, of cells from the gastric caeca and posterior stomach in larvae exposed during 2 or 24 h to the entomopathogen. A similar labeling pattern was observed in ultrathin sections from both midgut regions when incubated with BinB antiserum.     

斯蒂齿斑摇蚊的再描述(双翅目:摇蚊科)

对摇蚊科（Chironomidea）斑摇蚊属（Stictochironomus Kieffer,1919）斯蒂齿斑摇蚊[S.sticticus（Fabricius,1781]进行了再描述,并纠正Wang（2000）中所记录的辽宁省分布的S.sticicus（Fabricius）为S.akizukii（Tokunaga）。     

帽儿山溪流昆虫纲双翅目大蚊科稚虫分属分类检索

2011年7月和9月,在东北林业大学帽儿山实验林场溪流利用索伯网和D型网对水生昆虫进行调查和取样,根据外部形态特征对其中的双翅目大蚊科的幼虫进行了物种鉴定,共鉴定出11个属,编写了该区域大蚊科稚虫分属检索表,并对重要检索特征进行了图示。

为害柑桔春芽的达瘿蚊属二新种(双翅月:瘿蚊科)

广东省一些县市的柑桔春芽期受到瘿蚊科幼虫的危害,经调查与饲养发现有两个同属的近似种混合发生。本文为分类鉴定部分,优势种被命名为桔芽达瘿蚊(Dasincuracitrigemmia Yang et Tang),另一种则称为桔孪达瘿蚊(D.citrigemina Yang et Tang),描记了新种的成虫和幼期,与近似种进行了比较。

本文对我国食蚜亚科昆虫的区系进行了分析。我国该亚科昆虫的区系具备以下特点：东洋区与古北区种类所占比重较大，两者分别占总种数的３０．１０％和２８．０６％，几乎相等；而特有种和广布种较为丰富；以食蚜蝇族的区系最具多样性。     

Populational dynamics of Stomoxys calcitrans (Linneaus) (Diptera: Muscidae) in three biocenosis, Minas Gerais, Brazil

Populational flux of the adult phase of Stomoxys calcitrans was observed in the municipal district of Pedro Leopoldo, Minas Gerais, Brazil. Three biocenoses were selected for the study: stable agrobiocenosis, pastural agrobiocenosis and eubiocenosis. The occurrence and the populational flux of the insects, using the Magoon trap for their capture, were established. For each trap located in different biocenoses, a crossbred calf (Bos taurus × Bos indicus) approximately 6-month-old was used as “live bait,” exposed weekly for 48 h in the traps. Of the three agrobiocenoses studied, the stable agrobiocenosis contributed the greatest number of specimens of. S. calcitrans captured, corresponding to 96.9% of the total flies of this species collected. S. calcitrans shows seasonal behavior for approximately 6 months (spring and summer being the rainiest months of the year). The population peaked during the months of November and December. During the months of July and August, there was no capture of flies.
