Temporal Variation in Species Abundance and Richness of Culicoides (Diptera: Ceratopogonidae) in a Tropical Equatorial Area

Abstract: The aim of this study was to investigate whether temperature, rainfall, and humidity influence the annual distribution of Culicoides Latreille 1809, species abundance and richness in rural areas on São Luís Island in the state of Maranhão, Brazil. Biting midges were collected in housing for domestic animals in the peridomestic areas of 10 homes. A CDC light trap was installed in each peridomestic area from 6:00 p.m. to 6:00 a.m. once a month for 12 mo. In total, 23,633 individuals belonging to 26 Culicoides sp… Show more

“…Foxi et al 53 also reported relatively poor tolerance of Culicoides to lower temperatures. Eventhough it is not evident in our multivariable negative binomial regression models, previous study by Gusmão et al 21 suggests that persistent or heavy rain can create conditions for biting midges to proliferate but it can also be a barrier to the activity of adult (winged) biting midges and prevent them from flying. Rain can prevent adults from leaving their shelters and could affect catch.…”

“…In our study, rainfall amounts 4 and 8 weeks prior to trapping significantly impacted the abundance of C. biguttatus and was associated with both a decrease in abundance [4 weeks prior (0.1–2.6 mm category), and 8 weeks prior (2.2–72.0 mm category)]. Too much rain may discourage midges from activities such as foraging or mate-seeking [ 53 ], which may explain the decrease in abundance of C. biguttatus in the higher rain categories. Culicoides biguttatus tend to emerge early in the season (i.e., spring) and emergence longevity depends on environmental moisture levels [ 54 , 56 ].…”

“…While temperature has been proposed to positively influence Culicoides spp. abundance in some temperate regions [ 52 , 53 ], there are temperature thresholds at which abundance is negatively impacted for some Culicoides spp. [ 5 ].…”

“…biestroi has been recorded for the first time for the island of São Luís and for MA. This may be explained by the fact that this work was performed in a natural environment, whereas most previous entomological surveys were conducted in rural and urban areas (Silva and Rebêlo 1999, Carvalho and Silva 2013, Costa et al 2013, Silva and Carvalho 2013, Bandeira et al 2017, Gusmão et al 2019).…”

“…Some entomological surveys were carried out in forested areas, especially in Central Amazonia (Goeldi 1905, Castellón et al 1990, Farias et al 2015, 2016), and some were conducted in coastal areas in the state of Pará (Trindade and Gorayeb 2010). In the state of Maranhão (MA) in Brazil, studies have focused on their blood sources (Gusmão et al 2015), leishmania infection in endemic areas of cutaneous leishmaniasis (Rebêlo et al 2016), influence of environmental management and animal shelters on vector control (Bandeira et al 2017), and other ecological aspects (Barros et al 2007, Gusmão et al 2019, Silva and Carvalho 2013).…”
