Plant bugs (Hemiptera: Miridae) associated with pastures in Colombia 

Abstract

Eight species of the family Miridae found in Colombian pastures belong to four genera: Collaria, Cynodonmiris, Neotropicomiris and Stenodema. All species are included in the tribe Stenodemini and are associated with Poaceae grasses. Diagnosis, keys to species and genera, and distribution in Colombian regions as well as the principal host of these species are presented. Habitus and male genital structures illustrations for each species are provided to facilitate their recognition.

Life cycle and morphometric analysis of nymphs of Cynodonmiris corpoicanus Ferreira & Barreto, 2013 (Hemiptera: Miridae)

“…Abdomen reddish brown with pale spots (Ferreira et al 2013). This mirid share habitat with another grass bugs belonging to the Stenodemini: Collaria scenica (Stål, 1859) (primary pests of pastures), Collaria oleosa (Distant, 1883) and Stenodema andina Carvalho, 1975 (secondary pests) which affect Poaceae pastures (Barreto Triana and Osorio Mejía 2015;Barreto-Triana et al 2018).…”

New record of Microtechnites bractatus (Say) (Hemiptera: Miridae) infesting Crotalaria spp. and injuries of Miridae in cultivated plants in the State of Paraná, Brazil

“…On the other hand, Collaria is currently composed of 14 species distributed among the Afrotropical, Nearctic and Neotropical regions and C. scenica is found in Uruguay, Argentina, Brazil and Colombia (Morales et al, 2016;Barreto-Triana et al, 2018). These species are generally associated with Poaceae, such as wheat (Triticum aestivum), oats (Avena sp.…”

“…These species are generally associated with Poaceae, such as wheat (Triticum aestivum), oats (Avena sp. ), ryegrass (Lolium multiflorum), corn (Zea mays) among others (Barboza et al, 2011;Barreto-Triana et al, 2018). The damage caused by C. scenica is characterized by whitish streaks along the leaf blade, caused by the insertion of the buccal apparatus in the longitudinal direction of the leaf veins and feeding from the cellular content (Martinez and Barreto, 1998).…”
