Influence of Chironomidae (Diptera) faecal pellet accumulation on lake sediment quality and larval abundance of pestiferous midge Glyptotendipes paripes

Original language description

Two opposite distribution patterns of larval Glyptotendipes paripes in relation to organic carbon content in sediments of central Florida lakes were discovered. In a majority of examined lakes, G. paripes larvae were most abundant in sand sediment and their density rapidly declined with increased carbon content (type 1 lakes); however, in some cases the opposite was true (type 2 lakes). To elucidate this anomaly, field-collected organic sediments from types 1 and 2 lakes and sand sediment were studied for G. paripes development in the laboratory. Type 1 organic sediment consisted predominantly of fine particles (<0.25 mm diameter) with low dissolved oxygen levels, whereas type 2 organic sediments consisted primarily of chironomid large faecal pellet aggregates (> 0.25 mm diameter] with significantly higher levels of dissolved oxygen concentrations that were similar to sand sediment. Type 2 organic sediment and sand sediment were conducive to higher survival of G. paripes larvae than...

Vliv akumulace exkrementů pakomárů na vlastnosti sedimentu a abundanci larev škodlivého pakomára Glyptotendipes paripes

Czech description

Pakomár Glyptotendipes paripes vykazuje dva rozdílné typy rozšíření v jezerech střední Floridy. V některých jezerech se vyskytuje pouze v minerálním sedimentu při okraji, v jiných v organickém sedimentu ve středu jezer.Organický sediment jezer druhého typu je tvořen z větší části exkrementy pakomárů. Laboratorní pokusy ukazují, že tento sediment podporuje větší populační hustoty a rychlejší růst larev Glyptotendipes paripes.
