Heteroptera attracted to butterfly traps baited with fish or shrimp carrion

Coreidae, Cyrtocoridae, Miridae, Pentatomidae, Rhyparochromidae, ScutelleridaeAbstract
Records of Heteroptera collected at butterfly traps baited with fish or shrimp carrion during collecting trips to Bolivia, Brazil, Colombia, Ecuador, and Peru are presented. Traps consisted of a cylinder of net fabric (about 35 cm diameter × 75 cm length) attached on the top and bottom to square pieces of wood slightly larger than the diameter of the cylinder. The bait usually consisted of locally available fish or shrimp that were cut into small pieces and placed in a container with water and a little soil and allowed to putrefy for several days to a week or more before use. The Heteroptera collected consisted of 91 species and 1,712 specimens in the following families: Alydidae, Coreidae, Cyrtocoridae, Lygaeidae, Miridae, Pentatomidae, Reduviidae, Rhopalidae, Rhyparochromidae, and Scutelleridae. We collected 1,356 males and 356 females at these traps, but most of the sex bias occurred in the Scutelleridae. Although sex bias was variable by family, a bias towards females generally occurred except for the Scutelleridae. Most of the species collected at these traps were not collected at the location using other collecting methods, so collecting at butterfly traps increased the number of taxa obtained at each location. Butterfly traps baited with fish or shrimp carrion should be considered as an additional collecting tool for biodiversity studies or general collecting.
Resumen
Se presentan los registros de los Heteroptera recolectados en trampas mariposa cebadas con carroña peces o camarones durante una gira de recolección a Bolivia, Brasil, Colombia, Ecuador y Perú. Las trampas consistían en un cilindro de tejido de red (longitud de aproximadamente 35 cm de diámetro x 75 cm) unida en la parte superior e inferior de piezas cuadradas de madera ligeramente mas grandes que el diámetro del cilindro. El cebo generalmente consistía de pescado o camarones localmente disponibles que se cortaron en trozos pequeños y puestos en un recipiente con agua y un poco de tierra y se deja pudrirse durante varios días a una semana o más antes de su uso. Los Heteroptera recolectado consistieron de 91 especies y 1,712 ejemplares en las siguientes familias: Alydidae, Coreidae, Cyrtocoridae, Lygaeidae, Miridae, Pentatomidae, Reduviidae, Rhopalidae, Rhyparochromidae y Scutelleridae. Se recogieron 1,356 machos y 356 hembras en estas trampas, pero la mayor parte del sesgo sexual sucedio en el Scutelleridae. Aunque el sesgo de sexo fue variable por la familia, un sesgo hacia las hembras en general, se produjo con la excepción de la Scutelleridae. La mayor parte de las especies recolectadas en estas trampas no se recolectaron en el lugar utilizando otros métodos de recolección, por lo tanto, la recoleción en las trampas mariposa aumentó el número de taxones obtenido en cada lugar. Trampas mariposa cebadas con carroña de peces o camarones deben ser considerados como una herramienta de recoleción adicional para estudios de biodiversidad o recoleción general.
