“…Although the consumption of synanthropic insects was lower than that of the other groups, we found other prey associated with human habitats, such as Culex and Chrysomya mosquitoes. Culex declarator is the primary vector of St. Louis encephalitis and other arboviruses [ 61 ]. In Brazil, densely populated cities are infested by Culex and Aedes mosquitoes.…”

Going out for dinner—The consumption of agriculture pests by bats in urban areas

Insectivorous bats provide ecosystem services in agricultural and urban landscapes by consuming arthropods that are considered pests. Bat species inhabiting cities are expected to consume insects associated with urban areas, such as mosquitoes, flying termites, moths, and beetles. We captured insectivorous bats in the Federal District of Brazil and used fecal DNA metabarcoding to investigate the arthropod consumed by five bat species living in colonies in city buildings, and ascertained whether their predation was related to ecosystem services. These insectivorous bat species were found to consume 83 morphospecies of arthropods and among these 41 were identified to species, most of which were agricultural pests. We propose that bats may roost in the city areas and forage in the nearby agricultural fields using their ability to fly over long distances. We also calculated the value of the pest suppression ecosystem service by the bats. By a conservative estimation, bats save US$ 94 per hectare of cornfields, accounting for an annual savings of US$ 390.6 million per harvest in Brazil. Our study confirms that, regardless of their roosting location, bats are essential for providing ecosystem services in the cities, with extensive impacts on crops and elsewhere, in addition to significant savings in the use of pesticides.

“…To assess the toxicity of SARS-CoV-2 proteins on aquatic biota, we used larvae of a species distributed worldwide ( Samy et al, 2016 ) and highly anthropophilic, Culex quinquefasciatus ( Vieira et al, 2020 ). In addition, the species has recognized importance in public health, as it acts as the main vector of the periodic Wuchereria bancrofti (which causes lymphatic filariasis) ( Shenoy, 2008 ; WHO, 2010 ; Samy et al, 2016 ; King, 2020 ), and it is a secondary vector of different human arboviruses ( Lima-Camara, 2016 ; Pesko & Mores, 2009 ; Romero-Alvarez et al, 2018 ).…”

Knowledge about how the COVID-19 pandemic can affect aquatic wildlife is still extremely limited, and no effect of SARS-CoV-2 or its structural constituents on invertebrate models has been reported so far. Thus, we investigated the presence of the 2019-new coronavirus in different urban wastewater samples and, later, evaluated the behavioral and biochemical effects of the exposure of Culex quinquefasciatus larvae to two SARS-CoV-2 spike protein peptides (PSPD-2002 and PSPD-2003) synthesized in our laboratory. Initially, our results show the contamination of wastewater by the new coronavirus, via RT-qPCR on the viral N1 gene. On the other hand, our study shows that short-term exposure (48 h) to a low concentration (40 μg/L) of the synthesized peptides induced changes in the locomotor and the olfactory-driven behavior of the C. quinquefascitus larvae, which were associated with increased production of ROS and AChE activity (cholinesterase effect). To our knowledge, this is the first study that reports the indirect effects of the COVID-19 pandemic on the larval phase of a freshwater invertebrate species. The results raise concerns at the ecological level where the observed biological effects may lead to drastic consequences.

“…It has been previously demonstrated that changes in the landscape can lead to an increase in some etiological agents which vector species may spread, such as those that cause malaria and yellow fever (Baeza et al 2017;Wilk-da-Silva et al 2020). Other studies point to the positive relationship between high temperatures and the abundance of some species of mosquitoes (Vieira et al 2020). They also reveal that in tropical areas the seasonality of rainfall may be the main factor of variation in the composition and structure of mosquito communities (Julião et al 2010).…”
