“…frugiperda moths was approximately 10 moths per hectare (ha) ( Table 1 ), we calculated that one bat consuming two moths per night could reduce the S. frugiperda population by 20%. The maize crop is infested with one caterpillar for every 10 plants, generating a population of 4,000 caterpillars per ha [ 36 ]. In this way, the 5 female moths flying each night can generate a population of 4,000 caterpillars per ha.…”

“…First, we used previously published data to estimate the initial population of S . frugiperda in a 1-ha crop land [ 36 ], calculating the approximate abundance of S . frugiperda for several crops, including maize, in one harvest per season per year in the Brazilian Federal District from 2013 to 2017.…”

“…frugiperda was assumed to take place in November, December, and January, as reported by local farmers. We considered the mean number of moths collected by Fonseca-Medrano et al [ 36 ] during maize harvests from 2013 to 2017 ( Table 1 ) and divided it by the number of months related to the critical period of S . frugiperda (3 months) to obtain the number of moths per night per ha as the initial moth population ( N i ).…”

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.

“…3). Studies conducted in 2013 in the same area (Embrapa Cerrados) revealed that, in November, a large number of Lepidoptera (Santos et al, 2017;Piovesan et al, 2018;Fonseca-Medrano et al, 2019) and other insects, including Coleoptera, were collected and associated with high precipitation. This suggests that there may be annual variation in Coleoptera abundance as a function of climatic inter-annual variation.…”

“…In Brazil, the most widely used model in agriculture is the "Luiz de Queiroz" trap, fitted with a black light fluorescent lamp (Silveira Neto et al, 1976). The most common black light fluorescent lamp used in current research and IPM is the 15 W BL T8 (Branco et al, 2016;Medrano et al, 2019).…”

This study aimed to present the design and field test results of an LED (light emitting diode) lamp for integrated pest management (IPM) and other entomological studies. The light spectrum of the LEDs was tuned to optimize insect attraction and lower energy consumption. An electronic circuit with control software was integrated with the lamp, enabling it to operate in standalone mode, automatically identify night and day, monitor and control the battery charge with energy from a photovoltaic solar panel, protect the battery against over-discharge, and provide feedback about the operating status of the system. Additionally, energy consumption is about five times lower than that of the fluorescent lamp, reducing the battery and solar panel size needed for its energy supply. In the 2017/2018 growing season, the smart LED lamp was installed in a Sonne light trap in an irrigated rice field, and the total number of insects captured was compared with the number collected in a conventional light trap fitted with a traditional 15 W black light fluorescent lamp. Total captures in the Sonne trap were approximately three times greater than in the conventional system.
