“…Nevertheless, we did not measure body volume. Previous studies have suggested that predation rates for dragonfly naiads are higher than damselfly naiad rates, but have not been conclusive (Chatterjee et al, 2007;Mandal et al, 2008;Saha et al, 2012). The models showed that for both dragonfly and damselfly naiads the predation rates were highly dependent on predator and prey densities.…”

“…We observed much lower predation rates for both prey species than those in the existing literature. Chatterjee et al (2007) found predation rates of 66 mosquito larvae per day for Brachytron pratense, and Mandal et al (2008) found predation rates of 14, 25, 45, 57, and 64 mosquito larvae per day for Coenagrion kashmirum, Sympetrum durum, Rhinocypha ignipennis, Ischnura forcipata, and Aeshna flavifrons, respectively. However, these studies all used larger, older naiads (12.5 to 37.5 mm) compared to the current study.…”

“…Individuals of some odonate species have been shown to prey on numbers as high as 66 mosquito larvae per day (Chatterjee et al, 2007). Several studies have tried to quantify the effects of odonate predation on mosquito populations (Hirvonen and Ranta, 1996;Fincke et al, 1997;Stav et al, 2000;Mandal et al, 2008;Saha et al, 2012). Stav et al (2000) showed that odonate naiads caused a significant reduction in mosquito oviposition as well as a 100% reduction in mosquito emergence.…”

“…Odonata naiads are another group of mosquito larvae predators. They have not been extensively studied but show great potential in biological control (Mandal et al, 2008). Individuals of some odonate species have been shown to prey on numbers as high as 66 mosquito larvae per day (Chatterjee et al, 2007).…”

“…Blaustein and Chase [7] found that predator and larvae associations are likely to reduce the mosquito populations and thus could be an effective management tool for their control. Predators such as notonectids [11], belostomatids [11], dytiscid beetles [8,11], crustaceans [12], copepods [13], Odonata [14,15], wolf spiders (Araneae: Lycosidae) [16] and amphibians [11] have been shown to be potential biological control agents against mosquito species in various habitats such as agricultural drainages, rice fields and small water bodies. These habitats are some of the predominant larval habitats in the region for An.…”

Predation efficiency of Anopheles gambiae larvae by aquatic predators in western Kenya highlands

et al. 2011

BackgroundThe current status of insecticide resistance in mosquitoes and the effects of insecticides on non-target insect species have raised the need for alternative control methods for malaria vectors. Predation has been suggested as one of the important regulation mechanisms for malaria vectors in long-lasting aquatic habitats, but the predation efficiency of the potential predators is largely unknown in the highlands of western Kenya. In the current study, we examined the predation efficiency of five predators on Anopheles gambiae s.s larvae in 24 hour and semi- field evaluations.MethodsPredators were collected from natural habitats and starved for 12 hours prior to starting experiments. Preliminary experiments were conducted to ascertain the larval stage most predated by each predator species. When each larval instar was subjected to predation, third instar larvae were predated at the highest rate. Third instar larvae of An. gambiae were introduced into artificial habitats with and without refugia at various larval densities. The numbers of surviving larvae were counted after 24 hours in 24. In semi-field experiments, the larvae were counted daily until they were all either consumed or had developed to the pupal stage. Polymerase chain reaction was used to confirm the presence of An. gambiae DNA in predator guts.ResultsExperiments found that habitat type (P < 0.0001) and predator species (P < 0.0001) had a significant impact on the predation rate in the 24 hour evaluations. In semi-field experiments, predator species (P < 0.0001) and habitat type (P < 0.0001) were significant factors in both the daily survival and the overall developmental time of larvae. Pupation rates took significantly longer in habitats with refugia. An. gambiae DNA was found in at least three out of ten midguts for all predator species. Gambusia affins was the most efficient, being three times more efficient than tadpoles.ConclusionThese experiments provide insight into the efficiency of specific natural predators against mosquito larvae. These naturally occurring predators may be useful in biocontrol strategies for aquatic stage An. gambiae mosquitoes. Further investigations should be done in complex natural habitats for these predators.

Motivated by recent global initiatives for biodiversity conservation and restoration, this article reviews the gaps in our understanding of, and the challenges facing, freshwater macroinvertebrate biodiversity and conservation in tropical regions. This study revealed a lack of adequate taxonomic, phylogenetic, and ecological information for most macroinvertebrate groups, and consequently there are large‐scale knowledge gaps regarding the response of macroinvertebrate diversity to potential climate change and other human impacts in tropical regions. We propose ideas to reduce the impact of key drivers of declines in macroinvertebrate biodiversity, including habitat degradation and loss, hydrological alteration, overexploitation, invasive species, pollution, and the multiple impacts of climate change. The review also provides recommendations to enhance conservation planning in these systems (as well as providing clear management plans at local, regional, and national levels), integrated catchment management, the formulation of regulatory measures, the understanding of the determinants of macroinvertebrate diversity across multiple scales and taxonomic groups, and the collaboration between researchers and conservation professionals. It is suggested that the integrated use of macroinvertebrate biodiversity information in biomonitoring can improve ecosystem management. This goal can be facilitated in part by conservation psychology, marketing, and the use of the media and the Internet.
