| description | Cyrtomenus bergi Froeschner (Hemiptera: Cydnidae) is a polyphagous subterranean burrower bug reported on various crops and weeds in the field. Bionomics and population growth statistics of C. bergi while feeding on peanut (Arachis hypogaea L.), pinto peanut (Arachis pintoi, Krapovickas et Gregory), maize (Zea mays L.), sorghum (Sorghum bicolor [L.] Moench), welsh onion (Allium fistulosum L.),and sweet and bitter cassava (Manihot esculenta Crantz) were calculated from development time, survival of immature stages, and reproduction and female longevity under laboratory conditions. Free-choice host plant selection among peanut, maize and sweet cassava was recorded with separate rearings of C. bergi from the different hosts. Optimal performance ofC. bergi as measured by fecundity, survival, and intrinsic rate of population increase occurred on peanut and pinto peanut followed by maize. Sweet cassava, sorghum, and welsh onion were not favorable hosts, and C. bergi was unable to complete its life cycle on bitter cassava. In the free-choice test, insects reared on peanut and maize prior to the experiments were less active in their search for food, whereas insects reared on cassava prior to the experiment showed a clear preference for peanut and maize over cassava. Our results show that C. bergi is highly polyphagous, however, some host plants are strongly preferred over others. Cassava is not a preferred host and weeds in and around the cassava field may serve as alternative host plants that could maintain populations of C. bergi in cassava. |

Cyrtomenus bergi Froeschner (Hemiptera: Cydnidae) es un insecto barrenador subterráneo polífago que ha sido reportado en diversos cultivos y malezas en el campo. La bionomía y las estadísticas de crecimiento poblacional de C. bergi, mientras se alimentaba de maní (Arachis hypogaea L.), maní forrajero (Arachis pintoi, Krapovickas et Gregory), maíz (Zea mays L.), sorgo (Sorghum bicolor [L.] Moench), cebolleta (Allium fistulosum L.), yuca dulce y amarga (Manihot esculenta Crantz), se calcularon a partir de los datos sobre duración del desarrollo y supervivencia de las etapas inmaduras, reproducción y longevidad de las hembras en condiciones de laboratorio. Se registró la selección de plantas hospedantes en un ensayo de libre eleccin entre el maní, el maíz y la yuca dulce, empleando crías separadas de C. bergi de los diferentes hospedantes. Con base en los resultados de fecundidad, la supervivencia y la tasa intrínseca del aumento de población, el comportamiento óptimo de C. bergi se presentó en maní y en maní forrajero, seguido del maíz. La yuca dulce, el sorgo y la cebolleta no resultaron ser hospedantes favorables y C. bergi no pudo completar su ciclo de vida en la yuca amarga, En el ensayo de libre elección, los insectos criados en el maní y el maíz antes de los experimentos resultaron ser menos activos en la búsqueda de alimento, mientras que los insectos criados en la yuca antes del experimento mostraron una clara preferencia por el maní y el maíz respecto a la yuca. Los resultados indican que C. bergi es altamente polífago; sin embargo, este insecto muestra mayor preferencia por algunas plantas hospedantes que por otras. La yuca no muestra ser una planta hospedante preferida y malezas dentro y alrededor del cultivo de yucca pueda servir como planta hospedante alternativa manteniendo la población de C. bergi en la yuca.. 2005-03 2014-09-24T08:41:49Z 2014-09-24T08:41:49Z Journal Article https://hdl.handle.net/10568/43234 en Open Access Florida Entomological Society |
