AbstractA total of 167 blood-fed mosquitoes of the genera Ficalbia, Mimomyia and Uranotaenia was collected from the Kisumu area of Kenya using Monks Wood light-traps under the outside eaves of houses, CDC light-traps inside houses and sweep-net catches. Precipitin tests were used to obtain 72 positive identifications of the hosts, 89% of which were amphibia. M. mediolineata (Theo.) and M. splendens Theo. were shown to feed occasionally on man while U. balfouri Theo. and M. hispida (Theo.) were shown to feed on other mammals, including cattle. No identification was effected from a single F. uniformis (Theo.) specimen collected resting in vegetation. The medical importance of these mosquitoes is uncertain but, since there is evidence for several arboviruses in amphibia, further study of these potential vectors should be undertaken.

A study on diversity and abundance of grasshopper and its relatives (Orthoptera) was conducted at two mountainous rainforest ecosystems (Mounts Kendeng and Botol) of Gunung Halimun-Salak National Park. A hundred meters of a line transect was used to sample and set up several insect traps (yellow pan, malaise, pit fall, bait pit fall, sweep net, and light traps), and insect sweepings as well. The light traps were set up at about fifty meters distance from the end of the sampling sites. A total individual collected by traps was combined on every comparable sampling site. Total individuals of the Orthoptera captured were 414; consisted of 25 species of 9 families. Both species diversity and number of families were higher at Mount Kendeng rather than Mount Botol. Number of species of each family usually similar except on family of Grillidae was much higher at Mount Kendeng. Species belong to Phasmidae was not recorded at Mount Kendeng, while species belong to both families of Gryllotalpidae and Tettigonidae were not captured at Mount Botol as well. Overal there was a difference in the species richness at each between. Shannon Diversity Index (H’) and evenness (E) were higher at Mount Kendeng (2.44 and 0.81) rather than Mount Botol (1.80 and 0.66). Similarity Index of Jaccard (Cj) and Sorenson (Cn) of both localities were similar (0.40 and 0.32). Herbivores were most dominant at both localities (Phasmidae, Tetrigidae, Acrididae, Gryllidae, dan Gryllotalpidae), followed by omnivores (Blattidae), scavenger (Gryllacrididae), and predator (Mantidae).

This study focused on species of Heimbra Cameron, 1909 (Hymenoptera, Eurytomidae, Heimbrinae), a small genus of chalcid flies poorly represented in entomological collections, from two Brazilian savanna areas in Central Brazil. The surveys were carried out with Malaise, Moericke, light traps and sweep net and lasted from February 2018 to May 2019. Herein we provide new geographical records to H. opaca (Ashmead, 1894) and H. parallela Stage & Snelling, 1986.

<p>Anak Krakatau Island is a volcanic island in the Krakatau preservation complex. With its regular explosions, ranging from2 80 times/day in the year 2013, it was expected that the biodiversity would experience many changes. In orderto determine the recent condition of the biodiversity, especially animal inhabitants, a survey was conducted within the island in June, 2013. The survey was made for mammal, bird, reptile, and invertebrate(ground, aerial, and arboreal) diversity. For mammals, 10 live traps were used along 100 m of line transect, birds and reptiles were adopted faced encountered method, while the invertebrate survey was conducted with visual techniques with a sweep net, pit-fall traps, and light traps. The result from the inventory (especially invertebrate) was followed by determining the diversity and dominance of species. Relative abundancewas also determined for mammals only. The survey indicated that there was 1 species of mammal with 20% of relativeabundance, 13 species of birds within 11 families, 2 species of reptiles, 58 species of insect, and 10 species of non-insect invertebrates, which consisted of 6 species of Araneae, 2 species of Scorpiones, 2 species of Chilopoda. The diversity indexfor insects was 4.011 with Bothriamyrmex sp. as subdominantin which its index of 2.86, and index for non-insects was 2.079. The result also was compared with the other 3 islands of the Krakatau complex and data collected in the last 10 years.</p><p><br /><strong>Keywords</strong>: Anak Krakatau, volcanic, biodiversity</p>

The Relationship

The focus of this study is to find the relationship between El Nino and dengue fever cases in the study area.Mosquito density was recorded with the help of light traps and through aspirators collection. Climate data were obtained from National Meteorology and Environment centre. (Year wise El Nino and La Nina data are according to NOAA & Golden Gate Weather Services). Statistical methods were used to establish the correlation coefficient between different factors. A high significant relationship was observed between Relative Humidity and Dengue fever cases, but Aedes abundance had no significant relationship with either Relative humidity and Temperature. Our conclusion is that the El Nino does not affect the dengue transmission and Aedes mosquito abundance in this region, which is supported by earlier works.

New Distribution

The holarctic moth genus Catocala Schrank (1802) (Erebidae: Erebinae, Catocalini) includes about 300 species that are often monophagous on oak (Quercus), willow (Salix) and poplar (Populus). In this research, we studied the moths of the genus Catocala in Iran that were collected by light traps in different Iranian provinces, mostly during 2010–2018. Our results revealed eight species and two subspecies of Catocala from the provinces of Kermanshah, Lorestan, Chaharmahal-va Bakhtiari, Ilam, Khuzestan, Kohgiluyeh-va Boyerahmad, Fars, Kerman, Khorasan-e Jonubi, Yazd and Khorasan-e Razavi. Among the records there are 14 new provincial records. Overall, we list 20 species and four subspecies of Catocala as occurring in Iran. This list is compiled from our own research and a review of existing literature.

Background: Tricyclic psychotropic drugs are defined as a tricyclic rings of the dibenzazepine group with the presence of sulfur and nitrogen atoms. They have been prescribed for antidepressive therapy over the years. Due to their medical importance, many analytical methods have been developed for their monitoring. However, benefits of electrochemical techniques such as costeffectiveness, fast, easy operation and non-destructiveness make them appropriate analytical methods for drug assays. Electrochemical determinations of pharmaceuticals require suitable working electrodes. During years, many electrodes are modified by a variety of modifiers and several sensors were developed based on them. In this regard, nanomaterials, due to their remarkable properties, are one of the most important choices. Objective: Here, the application of electroanalytical methods in the determination of electroactive tricyclic psychotropic drugs will be reviewed and the nanomaterials which are used for improvements of the working electrodes will be considered.
