“…The correlation is possibly caused by preys (food) that are more abundant at locations with increased nutrient concentrations (Maul et al 2004). This is supported by previous studies which demonstrated that Corixidae feed on stream bottom organic matter containing algae, diatoms (Alahmed et al 2009;Cummins 1973;Sweeney & Schnack 1977) and Gerridae feed on detritivores and small arthropods at or near water surface that could be more abundant related to increasing nutrient concentrations (Cummins 1973;Jardine et al 2008;Sih & Watters 2005). Fernandez and Lopez Ruf (2005) reported that Gerridae was found in streams that subjected to agricultural and cattle-rearing activities in La Plata estuary, Argentina.…”

“…The possibility that Sigara could feed on larger invertebrates, including insect larvae, has been rarely considered. For example the review of Shaalan & Canyon (2009) on predatory insects feeding on mosquitoes lists only one study reporting predation by Sigara hoggarica on mosquitoes ( Alahmed, Alamr & Kheir, 2009 ); all other hemipterans in their review were members of the family Notonectidae. Nevertheless, the ability to feed on large prey, even larger than the predator, seems to be common among suctorial predators ( Klecka & Boukal, 2013 ; Nakazawa, Ohba & Ushio, 2013 ).…”

The role of a water bug,Sigara striata, in freshwater food webs

Freshwater food webs are dominated by aquatic invertebrates whose trophic relationships are often poorly known. Here, I used laboratory experiments to study the role of a water bug, Sigara striata, as a potential predator and prey in food webs of stagnant waters. Multiple-choice predation experiment revealed that Sigara, which had been considered mostly herbivorous, also consumed larvae of Chironomus midges. Because they often occur in high densities and are among the most ubiquitous aquatic insects, Sigara water bugs may be important predators in fresh waters. A second experiment tested the role of Sigara as a potential prey for 13 common invertebrate predators. Mortality of Sigara inflicted by different predators varied widely, especially depending on body mass, foraging mode (ambush/searching) and feeding mode (chewing/suctorial) of the predators. Sigara was highly vulnerable to ambush predators, while searching predators caused on average 8.1 times lower mortality of Sigara. Additionally, suctorial predators consumed on average 6.6 times more Sigara individuals than chewing predators, which supports previous results hinting on potentially different predation pressures of these two types of predators on prey populations. The importance of these two foraging-related traits demonstrates the need to move from body mass based to multiple trait based descriptions of food web structure. Overall, the results suggests that detailed experimental studies of common but insufficiently known species can significantly enhance our understanding of food web structure.

“…Excluding mosquito larvae, insects were identified to order, family, genus and species using a microscope and references (Mori & Kitayama, 2002; Kawai & Tanida, 2005). On the basis of the literature (Mogi, 2007; Alahmed et al , 2009; Saha et al , 2010), insects were classified as potential mosquito predators (e.g. Coleoptera, Heteroptera and Odonata) or non‐mosquito preys of predators (e.g.…”

Fallow field biotopes that develop from abandoned rice fields are man-made wetlands that provide new habitats for various aquatic animals. Although consideration of such biotopes generally focuses on their positive aspects, this study evaluated the negative aspects of establishing fallow field biotopes with regard to mosquito breeding sites. To determine whether fallow field biotopes become breeding habitats for vector mosquitoes, we evaluated mosquito fauna in fallow field biotopes and adjacent rice fields. We found larvae of Anopheles lesteri, Anopheles sinensis and Culex tritaeniorhynchus (all: Diptera: Culicidae) in the biotopes. Although abundances of mosquito larvae in the biotopes and rice fields were statistically similar, mosquito abundances in rice fields increased dramatically in August when the water level reduced after the rainy season. The abundance and variety of the mosquitoes' natural predators were greater in biotopes than in rice fields because the former are a permanent and stable aquatic environment. A generalized linear mixed model showed a negative effect of predator diversity on mosquito larvae abundance in both habitats. Although fallow field biotopes become breeding habitats for vector mosquitoes, establishing biotopes from fallow fields in order to protect various aquatic animals, including mosquito insect predators, may help to control mosquito breeding.
