Herbivore natural enemies base their foraging decision on information cues from different trophic levels but mainly from plant odors. However, the second trophic level i.

The Cercopidae family constitute the largest group of xylem sap-sucking insects. Several species are important pests of sugar cane and grasses. In America there are species and 65 subspecies in 60 genera. In Mexico, the total number of species is unknown and there is no inventory of specimens in the collections or taxonomic keys. In the present research, we study entomological collections to trace the distribution of genera and species and constructed taxonomic keys for their identification, based on external morphology and male genitalia.

Diagnostic taxonomic characters of pronotum, posterior border of abdominal segment VII, male genital capsule pygophore and parameres are illustrated. An identification key based mainly on the male genitalia is included. Como resultado de este estudio se describen comonuevas 5 especies y una P. Rasgos comunes para las especies nuevas. Membrana hemelitral. Segmentos conexivales del abdomen amarillos y con el tercio anterior negro borde anterior amarillo. Pselliopus cosmopolites n. Holotipo macho. Clavus y corium pardo claro. Segmentos dorsales negros y con el margen posterior del VII amarillo. Amarilla y con una franja longitudinal negra que corre de la zona postocular al cuello.

The hemiptera are divided into four smaller groups based on their physical features. These groups include aphids, mealybugs, and scale insects; cicadas and hoppers; moss bugs; and true bugs. The relationships of whiteflies are uncertain, and they are sometimes included with aphids or hoppers. Hemipterans are extremely variable in form, ranging from long, slender, and sticklike, to short and round, to very flat. The bodies of female scale insects are completely covered by a waxy shield. They don't even look like insects. Still other species are partially or completely covered in protective secretions of white wax that resemble dust, cotton, or feathers. The wax hides their bodies from predators and helps to seal in moisture. Hemipterans range in size from 0.

Se caracterizan por presentar dos pares de alas muy notorias que, en algunas especies, se encuentran endurecidas. Este orden fue descrito por primera vez en por el reconocido naturalista sueco Carlos Lineo. Se estima que hay unas Este grupo de insectos ha sido ampliamente estudiado, ya que muchas de sus especies son conocidos vectores para enfermedades temibles como el mal de Chagas o bien constituyen plagas de cuidado para muchos cultivos.

Cerci, for example, are entirely absent in all living paraneopterans some taxonomists classify this group as the superorder Acercaria, meaning without cerci. Perhaps the most significant hallmark of the paraneopteran lineage is a progressive development of haustellate mouthparts, variously adapted for scraping food from a substrate or gathering it by suction in liquid or semi-liquid form. Mouthparts of this type are distinctive because one or more of their structural components is elongated to form a rod or a stylet.
