Hemípteros / pulgones / cochinillas
Hemiptera /hɛˈmɪptərə/ (Latín hemipterus (“half-winged”)) o insectos verdaderos son una orden de insectos que comprenden más de 80 000 especies en grupos tales como cigarras, pulgones, saltamontes, chicharritas, chinches y chinches verdes. Varían en tamaño desde 1 mm (0,04 pulgadas) hasta alrededor de 15 cm (6 pulgadas) y comparten una disposición común de piezas bucales de succión.[3] El nombre "insectos verdaderos" a menudo se limita al suborden Heteroptera.[4] Muchos insectos comúnmente conocidos como "bichos", especialmente en inglés americano, pertenecer a otras órdenes; por ejemplo, el bicho del amor es una mosca[5] y el cochorro y la mariquita son escarabajos.[6]
La mayoría de los hemípteros se alimentan de plantas, utilizando sus piezas bucales chupadoras y perforadoras para extraer la savia de la planta. Algunos son hematófagos, mientras que otros son predadores que se alimentan de otros insectos o pequeños invertebrados. Viven en una amplia variedad de hábitats, generalmente terrestres, aunque algunas especies están adaptadas a la vida en o sobre la superficie del agua dulce. Los hemípteros son hemimetábolos, con jóvenes ninfas que se parecen un poco a los adultos. Muchos pulgones son capaces de realizar la partenogénesis, produciendo crías a partir de huevos no fertilizados; esto les ayuda a reproducirse extremadamente rápido en condiciones favorables.

Abstract,Pest Management in Horticultural Ecosystems, 2010 Soil ameliorants, botanicals, chemical insecticides and fungal bio-agents were screened against banana root mealybug, Geococcus spp. Among the soil ameliorants, application of sodium silicate and calcium oxide at the time of planting...
- Scale insects and mealybugs are ubiquitous in managed landscapes. Although they are most commonly managed in the landscape on ornamental plants, this group of insects can also be damaging pests of warm season turfgrasses. To date, little research has investigated management strategies for these...
- It’s human nature to ignore what you don’t see. Why worry about something if you can’t see it? As growers, you may notice the plant is stunted and not growing well. Until you take the plant out of the pot and look at the root system, then the wax associated with root mealybug becomes noticeable....

Abstract, Proceedings - Biological Sciences, 2007 Interactions between ants and honeydew-producing hemipteran insects are abundant and widespread in arthropod food webs, yet their ecological consequences are very poorly known. Ant–hemipteran interactions have potentially broad ecological effects,...
