Asian Citrus Psyllid, Diaphorina citri Kuwayama (Insecta: Hemiptera: Psyllidae)

Abstract

Revised! EENY-033, an 8-page illustrated fact sheet by F.W. Mead and T. R. Fasulo, is part of the Featured Creatures collection. It describes this serious pest of citrus which is a vector for citrus greening disease or Huanglongbing — identification, distribution, description, life history, damage, and management. Includes references. Published by the UF Department of Entomology and Nematology, July 2010. EENY-033/IN160: Asian Citrus Psyllid, Diaphorina citri Kuwayama (Insecta: Hemiptera: Psyllidae) (ufl.edu)

Host Suitability of Citrus andZanthoxylumSpp. forLeuronota fagaraeBurckhardt andDiaphorina citriKuwayama (Hemiptera: Psylloidea)

“…], commonly known as orange jasmine, are suitable hosts of D. citri . Females need to feed on buds and shoots with unexpanded leaves to mature eggs and to oviposit (Mead 1977;Chavan & Summanwar 1993). Eggs hatch in 2-4 days and nymphs go through 5 instars in 11-15 days for a life cycle of 13-17 days at the optimum range of 25-28 °C and up to 47 days at lower temperatures (Mead 1977;Chavan & Summanwar 1993;.…”

Under controlled conditions, populations reared on M. paniculata at 10 °C and 33 °C failed to develop, whereas survival of nymphal instars 3-5 was unchanged between 15 and 28 °C.…”

The situation of the Asian citrus psyllid (Diaphorina citriKuwayama) (Hemiptera: Liviidae), vector of Huanglongbing in Ecuador

“…Los ojos son marrón oscuro (García et al, 2016). Posee un aparato bucal chupador, que utiliza para extraer savia del floema de plantas sanas e infectadas, excreta una cera blanca y sólida que es sustrato para el desarrollo de hongos saprófitos, conllevando a la formación de fumagina (Tsai, 2008;Mead & Fasulo, 2010). Las siguientes características del ciclo biológico se resume de García et al (2016): presenta tres fases de desarrollo: huevo, ninfa y adulto (Figura 2).…”

Dissipation and Efficacy of Afidopyropen for Controlling Asian Citrus Psyllids Under Field Conditions

“…1,2 The pathogen, Candidatus Liberibacter asiaticus (CLas), causes HLB in the US and is vectored in citrus groves by Asian citrus psyllids (ACP) (Diaphorina citri Kuwayama) as it feeds on the citrus phloem. 1 No cure has been discovered for HLB despite numerous research efforts that have pursued potential treatments and management strategies. 3 Currently, the use of chemical insecticides to control ACP populations and prevent further disease spread is the primary HLB management strategy.…”
