Mecanismos de dispersión y resistencia al ayuno en Raoiella indica Hirst (Acari: Tenuipalpidae).
Provedor de dados: 32
Autores: Ramírez López, José.
El ácaro Raoiella indica Hirst es una especie fitófaga obligada que  en pocos años ha colonizado amplias zonas de América Tropical y ha causado severos daños, sobre todo a plantas de las familias Arecaceae y Musaceae.  El presente trabajo estuvo dirigido a evaluar atributos biológicos de esta especie que permitan explicar su potencial como plaga invasiva. Se estudiaron su capacidad para sobrevivir en ausencia de alimento y sus mecanismos de dispersión, incluyendo el desplazamiento pasivo en el viento y la posible asociación forética sobre insectos. Se determinó que este ácaro tiene una resistencia a la inanición superior a la de otros ácaros fitófagos, con un máximo de 12 días en hembras adultas. El principal mecanismo de dispersión es mediante corrientes...

Eucalyptus grandis Hill.ex. Maiden injuries caused by Ctenarytaina spatulata Taylor.
Provedor de dados: 190
Autores: Santana, Dalva Luiz de Queiroz; Zanol, Keti M. R.; Botosso, Paulo Cesar; Mattos, Patricia Póvoa de.
The injuries of Ctenarytaina spatulata Taylor, 1977, were characterized through observations in field,  laboratory and greenhouse. The first injuries of C. spatulata in Eucalyptus grandis are caused during  oviposition. At the point where the egg is inserted, a   small black spot appears, which may grow larger, causing the bud death. The insect eliminates large  amount of honeydew, accumulating on leaves and  apical parts, which starts the proliferation of sooty mold,  and fitopathogenic fungi. Leaves of the attacked  lants become deformed, smaller than the  normal ones, distorted, or with flaws among the ribs and sooty mold reducing the photosynthetic capacity.  Due to damages provoked by the bites, oviposition,  sooty mold accumulation and other fungi,...

Exotic Pests and Trade: When Is Pest-Free Status Certification Worthwhile?
Provedor de dados: 31
Autores: Lichtenberg,   Erik; Lynch,   Lori.
Pest-free status certification is desirable if the demand-side impacts (increased export revenue) and supply-side impacts (lower pest damage and decreased ongoing control costs) exceed the compliance monitoring and eradication costs. Thus, eradication may be optimal without certification. Certification is more likely for regions facing costly treatment requirements (bans) or possessing geographic traits that lower monitoring costs and infestation probabilities than for those exporting higher-valued products. Certification benefits producers but hurts consumers. Thus, political feasibility may be greater if domestic consumption is a small share of the market and if the additional tax burden of certification programs is light.
