The origin and population dynamics of annually re-occurring Paratanytarsus grimmii (Diptera: Chironomidae) colonising granular activated carbon (GAC) adsorbers used in potable water treatment.
Various sampling techniques were employed to study the population dynamics and identify the origin of annually re-occurring infestations of Paratanytarsus grimmii in granular activated carbon (GAC) adsorbers. Larvae overwintered in all adsorbers studied and are the main source of endemic persistent infestations. Significant differences in larval densities were identified between the down-flow c...
متن کاملNuisance midges (Diptera: Chironomidae) and their control in Japan.
In recent years, adult Chironomidae (particularly Chironomus yoshimatsui and Tokunagayusurika akamushi) emerging from polluted natural and man-made aquatic habitats in urban areas of Japan have become intolerable because they pose severe nuisance and economic problems. Several organophosphorus (OP) insecticides and insect growth regulators (IGRs) including methoprene and diflubenzuron were test...
متن کاملColonisation of temporary macrophyte substratum by midges \(Chironomidae: Diptera\)
This study investigates a phytophylous community of Chironomidae larvae on the submerged plant species Myriophyllum spicatum L. in a eutrophic lake (Lake Sakadaš, Danube floodplain area in Croatia) during summer 2004. This macrophyte species appeared for the first time in the lake in 2004, lasted approximately three months and was considered as a temporary habitat. The chironomid community was ...
متن کاملTwo new species of Paratanytarsus (Diptera: Chironomidae) from southeast of Brazil
The adults and immature stages of Paratanytarsus corbii sp. n. and the male adult of Paratanytarsus silentii sp. n. are described and illustrated. P. corbii larvae were collected on sediment and aquatic vegetation of the headwater of the Anhumas Reservoir (Américo Brasiliense, SP) and reared in laboratory to obtain the pupal exuviae and associated adults. The adult males of P. silentii were obt...
