This bacteria is transmitted by the Asian citrus psyllid, Diaphorina citri (Hemiptera) and there are no effective in-planta treatments for CLas. Therefore, one strategy is to manage the psyllid population. Manual annotation of the D. citri genome can identify and characterize gene families that could serve as novel targets for psyllid control. The yellow gene family represents an excellent target as yellow genes are linked to development and immunity due to their roles in melanization.

Its vector in the main produc- ing regions is the Asian citrus psyllid, Diaphorina citri Kuwayama, 1908 (Hemiptera: Liviidae). Brazil has the larg- est orange-growing area and is also the largest exporter of processed juice in the world. Since the first detection http://jipm.oxfordjournals.org/ of the disease in this country, >38 million plants have been destroyed and pesticide consumption has increased considerably. During early research on control methods, the parasitoid Tamarixia radiata (Waterston, 1922) (Hymenoptera: Eulophidae) was found in Brazil. Subsequent studies focused on its bio-ecological aspects and distribution in citrus-producing regions. Based on successful preliminary results for biological control with T. radiata in small areas, mass rearing was initiated for mass releases in Brazilian conditions. Here, we review the Brazilian experience using T. radiata in D. citri control, with releases at sites of HLB outbreaks, adjacent to commercial areas, in abandoned groves, areas with orange jessamine (a psyllid host), and backyards.

In the United States, D. citri was Þrst discovered in Florida, in 1998. Tamarixia radiata Waterston (Hymenoptera: Eulophidae) was imported from Asia and released in Florida in 1999Ð2001 to improve biological control of D. citri before citrus greening was detected in Florida in 2005. Florida citrus groves were surveyed during 2006Ð2007 for D. citri and T. radiata. Results showed that D. citri was established in all 28 citrus groves surveyed across 16 counties. Adult populations averaged 3.52, 1.27, and 1.66 individuals per “tap” sample at locations in the central, southwest, and eastern coastal regions, respectively. A tap sample consisted of 22- by 28-cm white paper sheet (on a clipboard) held under branches selected at random that were tapped three times. Averages of 67, 44, and 45% citrus shoots infested with psyllid eggs or nymphs were obtained in the central, southwest, and eastern coastal regions, respectively. T. radiata was recovered from fourth- and Þfth-instar psyllid nymphs at 26 of the 28 locations. However, apparent parasitism rates were variable and averaged Ͻ20% during spring and summer over all locations.

  • Biological Control of Diaphorina Citri (Hermosillo, Sonora
    Biological control of Diaphorina citri (Hermosillo, Sonora. México 2008) BIOLOGICAL CONTROL OF Diaphorina citri David G. Hall USDA-ARS, U.S. Horticultural Research Laboratory 2001 South Rock Road Fort Pierce, FL 34945 E-mail: [email protected] Key words: Psyllids. Huanglongbing, citrus disease greening ABSTRACT Diaphorina citri Kuwayama (Hemiptera: Psyllidae) is subjected to various levels of biological control throughout its geographic distribution. The species complex of biological control agents attacking D. citri varies geographically but usually includes various species of ladybeetles (Coleoptera: Coccinellidae); syrphid flies (Diptera: Syrphidae); lacewings (Neuroptera: Chrysopidae, Hemerobiidae); and spiders (Aranae). The psyllid is attacked in Asia by two primary parasitoid species, Tamarixia radiata (Waterston) (Hymenoptera: Eulophidae) and Diaphorencyrtus aligarhensis (Shafee, Alam & Agarwal) (Hymenoptera: Encyrtidae). Classical biological control projects have been conducted to establish these two parasitoids in a number of countries invaded by D. citri including Mauritius, Réunion Island, and the United States (Florida). T. radiata was successfully established in the United States, but D. aligarhensis was not. T. radiata was also released for psyllid control in Taiwan and Guadeloupe. Dramatic success in reducing populations of D. citri was achieved following releases and establishment of T. radiata in Réunion Island. Good levels of biological control were reported in Guadeloupe after this parasitoid was introduced. Mediocre biological control of D. citri has been achieved by T. radiata in the United States (Florida). T. radiata has been inadvertently introduced into other areas in the United States (Texas), Puerto Rico, Venezuela, and Brazil. T. radiata in India and other areas in Asia are attacked by a complex of hyperparasitoids.

  • To Infestations of Asian Citrus Psyllid, (Hemiptera: Psyllidae) in Florida
    608 Florida Entomologist 84(4) December 2001 NUMERICAL RESPONSE OF OLLA V-NIGRUM (COLEOPTERA: COCCINELLIDAE) TO INFESTATIONS OF ASIAN CITRUS PSYLLID, (HEMIPTERA: PSYLLIDAE) IN FLORIDA J. P. MICHAUD University of Florida, Citrus Research and Education Center, 700 Experiment Station Road, Lake Alfred, FL 33881 ABSTRACT Data are presented on the relative abundance of the coccinellid Olla v-nigrum (Mulsant) in Florida citrus, before and after invasion by the Asian citrus psyllid, Diaphorina citri Ku- wayama. Adults and larvae of O. v-nigrum were observed preying on immature psyllids throughout their range in Florida. Immature psyllids were eliminated by predation from many flushed citrus terminals that exhibited damage symptoms; pupae of O. v-nigrum and Harmonia axyridis Pallas were recovered from adjacent leaves. Olla v-nigrum, a relatively rare species before the invasion by D. citri, is now a dominant species throughout Florida in citrus groves where the psyllid is present, but remains rare in regions where D. citri is ab- sent. The strong numerical response of this native ladybeetle to D. citri populations indi- cates that it is assuming a key role in biological control of the psyllid. Key Words: abundance, biological control, coccinellids, Diaphorina citri, Harmonia axyridis, Olla v-nigrum RESUMEN Se presentan datos sobre la abundancia relativa del coccinélido Olla v-nigrum (Mulsant) en cítricos en la Florida, antes y después de la invasión del psílido Asiático, Diphorina citri Kuwayama.

  • Distribution, Biology, Ecology and Control of the Psyllid Diaphorina Citri Kuwayama, a Major Pest of Citrus: a Status Report for China
    International Journal of Pest Management, October – December 2006; 52(4): 343 – 352 Distribution, biology, ecology and control of the psyllid Diaphorina citri Kuwayama, a major pest of citrus: A status report for China YUEPING YANG1, MINGDU HUANG1, G. ANDREW C. BEATTIE2, YULU XIA3, GECHENG OUYANG1, & JINJUN XIONG1 1Guangdong Entomological Institute, Guangzhou, Guangdong, People’s Republic of China, 2Centre for Plant and Food Science, University of Western Sydney, Penrith South DC, New South Wales, Australia, and 3National Science Foundation Center for Integrated Pest Management, North Carolina State University, Raleigh, NC, USA Abstract The Asiatic citrus psyllid Diaphorina citri Kuwayama (Hemiptera: Psyllidae) is a major pest of citrus in China. Its status derives, not from the damage it causes, but from its role as the only known vector in China of huanglongbing, a phloem- limited bacterial disease of international importance. The disease can devastate orchards within a few years of planting. It also poses a major threat to endangered indigenous citrus germplasm in Asia and Australasia. The distribution, biology, ecology and control of the psyllid in China are reviewed in these contexts. Constraints and challenges related to control of the vector in China are discussed.
