Registros de Mantodea (Insecta) coletados à luz no dossel da floresta, na torre do km 14 do núcleo ZF-2, Manaus, Brasil

Abstract

Foram realizadas coletas mensais de insetos de janeiro a dezembro de 2004, durante três noites de transição lunar minguante/nova, das 18:00 às 06:00 horas. Os espécimes foram capturados em um lençol iluminado com lâmpada de 250 watts, luz mista de vapor de mercúrio e lâmpada de 20 watts black light (BL) e black light bulb (BLB). A armadilha foi montada a 45 metros de altura numa torre metálica de 50 metros, que ultrapassa a maioria das copas das árvores, num platô de terra firme, na bacia do rio Cuieiras, Manaus, Amazonas, Brasil. Foram coletados 23 espécies de Mantodea, sendo Chaeteessidae (1 espécie); Mantoididae (2); Mantidae (15); Thespidae (2) e Acanthopidae (3). Seis espécies são novas e serão descritas oportunamente nos seguintes gêneros: Cardioptera Burmeister, 1838, Phyllovates Kirby, 1904, Pseudovates Saussure, 1869, Stagmomantis Saussure, 1869, Stagmatoptera Burmeister, 1838 e Metilia Stal, 1877. Três espécies registradas para o Brasil sem uma região determinada estão sendo registradas para a Amazônia brasileira: Heterovates pardalina Saussure, 1872, Macromantis ovalifolia (Stoll, 1813) e Photina reticulata (Burmeister, 1838). Quatro registros são novos para o estado do Amazonas: Angela guianensis Rehn, 1906, Photina gracillis Giglio-Tos, 1915, Raptrix perspicua (Fabricius, 1787) e Vates festae Gigio-Tos, 1914. Os números de indivíduos, em cada coleta mensal, são apresentados para cada espécie.

Population survey of predatory insects in sugarcane in the municipality of União, Piauí state, Brazil, using light trap

“…They are voracious agricultural pest predators, playing an important role in agricultural ecosystems. According to Dantas et al (2008), this insect group has been little studied in Brazil, and a higher number of specialists are needed.…”

A new species of Microphotina Beier, 1935 from the southernmost region of Amazonia (Mantodea: Photinaidae)

“…Type locality in French Guiana, with additional records from that country in François & Roy (2015). Presumably the most widespread member of Microphotina, also reported from Venezuela (Cerdá 1997) and Brazil (Terra 1995;Dantas et al 2008). However, Venezuelan and Brazilian records require corroboration.…”

“…Likewise, the multi-taxa expedition that revealed M. viridula in French Guiana employed at least seven trapping methods capable of capturing Mantodea, yielding only thirteen specimens of Microphotina out of 398 praying mantis specimens obtained (Touroult et al 2018;Roy 2019). A canopy light trap survey in Manaus, Brazil (Dantas et al 2008) yielded only seven specimens of (presumably) M. vitripennis out of 254 samples. Pooling together the results from these studies and our own work at RPPN Cristalino, Microphotina represented only 26 (1.98%) out of 1313 specimens.…”

First Records of Mantodea (Insecta, Dictyoptera) from the Serra das Confusões National Park, Piauí State, Brazil

“…The species richness of the Neotropical region is considered low, mainly due to the scarce sampling efforts, low population densities, and few studies that have focused on Mantodea fauna (especially in the semiarid region of Brazil) (agudelo et al 2007;danTas et al 2008). The semiarid region of northeastern Brazil (including northern Minas Gerais State) is defined and delimited by average annual precipitation rates lower than 800 mm, and aridity indices below 0.5 (calculated as the relationship between precipitation and evaporation) and includes several plant formations such as caatinga and open rocky field vegetations, moist forests, seasonal forests, and Cerrado (Neotropical savannas) (QueiRoz et al 2006 .…”
