“…Some authors consider that a life cycle is short when last less than 12 days (G) (Danks 2006) and others establish a rank of 14 to 30 days as short (Strixino & Trivinho-Strixino 1985). In our study the average duration of G. holoprasinus generation time (G) indicates that this species has a short life cycle in temperatures around 26°C.…”

“…In contrast, the growth proportion for TBL had a high variability (Table 1) with an average r of 2.14. As stated by many authors, the more sclerotized structures (as the cephalic capsule) grow with gaps between moultings (Strixino & Trivinho-Strixino 1985), while the less sclerotized structures (as the abdominal segments) show continuous growth. Thus, the continuous length growth was the result of the resource exploitation capability of the organism, whereas the changes between instars were showed by cephalic increments.…”

“…Development times of the 1 st , 2 nd and the 3 rd instars of the Brazilian Chironomus population was shorter than that of the 4 th instar, as has also been observed in other Chironomus species (Fonseca and Rocha 2004; Zilli et al 2008). The 4 th instar’s long larval development time is probably due to the greatest body growth occurring in this period (Tokeshi 1995), as well the production and maturation of the oocytes (Strixino and Trivinho-Strixino 1985). …”

In most freshwater ecosystems, aquatic insects are dominant in terms of diversity; however, there is a disproportionately low number of records of alien species when compared to other freshwater organisms. The Chironomidae is one aquatic insect family that includes some examples of alien species around the world. During a study on aquatic insects in Amazonas state (Brazil), we collected specimens of Chironomidae that are similar, at the morphological level, to Chironomus kiiensis Tokunaga and Chironomus striatipennis Kieffer, both with distributions restricted to Asia. The objectives of this study were to provide morphological information on this Chironomus population, to investigate its identity using DNA barcoding and, to provide bionomic information about this species. Chironomus DNA barcode data were obtained from GenBank and Barcode of Life Data Systems (BOLD) and, together with our data, were analyzed using the neighbor-joining method with 1000 bootstrap replicates and the genetic distances were estimated using the Kimura-2-parameter. At the morphological level, the Brazilian population cannot be distinguished either from Chironomus striatipennis or Chironomus kiiensis, configuring a species complex but, at the molecular level our studied population is placed in a clade together with Chironomus striatipennis, from South Korea. Bionomic characteristics of the Brazilian Chironomus population differ from the ones of Chironomus kiiensis from Japan, the only species in this species complex with bionomic information available. The Brazilian Chironomus population has a smaller size, the double of the number of eggs and inhabits oligotrophic water, in artificial container. In the molecular analysis, populations of Chironomus striatipennis and Chironomus kiiensis are placed in a clade, formed by two groups: Group A (which includes populations from both named species, from different Asiatic regions and our Brazilian population) and Group B (with populations of Chironomus kiiensis from Japan and South Korea). Genetic distance between the Brazilian population and specimens in Group A suggests that it was recently introduced in Brazil, and that its country of origin is probably South Korea.

“…The experiments were conducted in 300ml glass beakers, with 95g of artificial substrate (75% fine sand, 20% clay white, 5% topsoil and 0.01% calcium carbonate) and 120 ml of reconstituted water (8 ml solution I: calcium sulfate (CaSo 4 ); 1000 ml distilled water and 4 ml solution II: potassium chloride (KCl); sodium hydrogen carbonate (NaHCo 3 ) ; 1.000 ml distilled water adjusted to hardness level of 16. Specimens were kept under static conditions at 25 ± 2°C and 12:12 hours light:dark regimen (STRIXINO & STRIXINO 1985). Before use, the sand was washed with tap water and sterilized in an oven for five hours at 100°C.…”
