Preventive measures to limit the spread of Trioza erytreae (Del Guercio) (Hemiptera: Triozidae) in mainland Europe

open access: yesJournal of Applied Entomology, Volume 144, Issue 7, Page 553-559, August 2020., 2020
Abstract Trioza erytreae (Del Guercio) (Hemiptera: Triozidae) vectors the most important citrus disease, namely huanglongbing (HLB) or citrus greening. This vector has been recently found on the European mainland in the north‐western region of the Iberian Peninsula (Spain and Portugal), although HLB has not yet been detected in Europe. Thus, preventing

Control alternativo de Diaphorina citri Kuwayama (HEMIPTERA: LIVIIDAE) utilizando caldo sulfocálcico

open access: yesBoletín Científico Centro de Museos Museo de Historia Natural, 2017
La concentración letal (CL) es usada para estimar la toxicidad de plaguicidas a artrópodos. Sin embargo, la CL es una medida incompleta de los efectos de los productos sobre poblaciones, pues analiza solamente la mortalidad como parámetro de toxicidad. Se sabe que individuos que sobreviven a la exposición a plaguicidas pueden sufrir efectos subletales.
