The diet of the four larval instars of a Chaoboridae species of Lake Monte Alegre, was evaluated through the analysis of the crop content of individuals caught at night in the lake. Peridinium and zooflagellates were the major components of the diet of instars I and II, whereas microcrustaceans, especially the cladoceran Bosmina, were most important for late instars. When the preferential prey decreased, in the course of the year, the diet was more diversified, increasing the ingestion of… 
Secondary production of Chaoborus ceratopogones (Diptera: Chaoboridae) in Lake Bosumtwi, Ghana
TLDR
Primary production of Chaoborus ceratopogones was determined to assess its role in the zooplankton community and growth rates were low in instar I and pupae, while transfer efficiency of chaoborus production to planktivorous fish may be low because of intense fishing pressure on the lake.
Water mite predation on zooplankton of a tropical lake.
TLDR
Water mite predation on zooplanktonic species from Lake Monte Alegre (São Paulo State, Brazil) was tested in laboratory experiments and older larvae were seen to be seized by several mites, both predators and prey sinking to the bottom of the vessel.
Mesocosm experiment on the impact of invertebrate predation on zooplankton of a tropical lake
TLDR
Copepod losses to predation in the experiment may be compensated by higher fecundity, shorter egg development time, and lower pressure on egg-bearing females, resulting in a lower susceptibility to Chaoborus predation.
Experiments on the influence of Chaoborus brasiliensis Theobald, 1901 (Diptera: Chaoboridae) on the diel vertical migration of microcrustaceans from Lake Monte Alegre, Brazil.
TLDR
The experiments indicated that Daphnia responded to physical contact with Chaoborus larvae but not to kairomones alone, and adult copepods seemed to be more sensitive to k airomones, as they were almost homogeneously distributed in the water column.
Day-Night Vertical Distribution and Feeding Patterns of Fourth Instar ofChaoborus Larvae in a Neotropical Reservoir (Socuy Reservoir, Venezuela)
TLDR
The results indicate that vertical migration may promote a spatial separation between larvae and zooplankton, and feeding activity of larvae occurred only when both overlapped.
Predation on microcrustaceans in evidence: the role of chaoborid larvae and fish in two shallow and small Neotropical reservoirs
This study was focused on the predation upon microcrustaceans by an invertebrate predator (chaoborid larvae), and vertebrate predators (fish), in two small reservoirs in southeastern Brazil, with and
The role of predation in the diel vertical migration of zooplankton in two tropical freshwaters ecosystems
Aim: This study aimed to examine and compare the different patterns of diel vertical migration (DVM) in two tropical freshwater ecosystems: Carioca Lake (PERD, MG), dominated by piscivorous fishes
Diel vertical migration of copepods in a Brazilian lake: a mechanism for decreasing risk of Chaoborus predation?
TLDR
The migratory pattern change for copepodites and adults might be related with a recent predation pressure increase by Chaoborus larvae on copepods, after the virtual disappearance of their main cladoceran prey.
Diel horizontal distribution of microcrustaceans and predators throughout a year in a shallow neotropical lake.
TLDR
The results indicated that DHM was not performed by the microcrustaceans and is not, therefore, a strategy for decreasing predation by both invertebrates, Chaoborus brasiliensis Theobald and Krendowskia sp.
Experiments on invertebrate predation on cladocerans and its relationships with lake data
Until recently, knowledge of the impact of invertebrate predators on cladocerans in the Brazilian Lake Monte Alegre was limited to a few species. In order to assess the effects of predation on other

Ecological studies on Chaoborus (Diptera, Chaoboridae) in Lake George, Uganda
TLDR
Chaoborus anomalus and Chaoborus ceratopogones were found together throughout the year in Lake George, Uganda, the larvae forming 65-85% by number of the macro-benthos of the central lake area, and the co-existing species are thought not to be competing for the same resources.
Feeding selectivity of a tropical Chaoborus population
TLDR
Diurnal variation between instars in food composition cannot be explained simply on the basis of the vertical distributions of predators and prey, but an interaction of vertical distribution with prey density and predator selectivity does explain the overall Chaoborus feeding pattern.
Zooplankton populations and the diets of three Chaoborus species (Diptera, Chaoboridae) in a tropical lake
TLDR
Zooplankton populations in a small, natural, tropical lake are dominated by a few, small-sized taxa including the copepod Thermo- cyclops consimilis, the cladoceran Moina micrura and several rotifer species, and algae have not been previously reported to be a large component of the diet of Chaoborus populations in nature.
Differential use of food resources by the instars of Chaoborus punctipennis
TLDR
The relationship between prey body width and Chaoborus gape diameter, coupled with knowledge of prey escape behaviour, should be useful for predicting the presence of hard-bodied prey taxa in diets of other Chaoborous species.

TLDR
At some times of the year, certain zooplankton populations (especially noncolonial rotifers, small copepods, and small cladocerans) were strongly influenced by Chaoborus predation.

TLDR
While Chaoborus can regulate zooplankton community structure in acidified, fish-free lakes, the frequency of occurrence of such control remains uncertain.
