“…In the Bahamas and Puerto Rico, for instance, this unintended spread is considered by some to be a fortuitous benefit to their ongoing and underfunded effort to control the spread of M. quinquenervia Pratt et al 2008). In California, where the tree is not considered invasive, land managers perceive the psyllid's arrival as an added complication to the aesthetic maintenance of the communities' street trees (Pratt and Arakelian 2011).…”

“…9.3, ESRI, Redlands, CA, USA). For each confirmed location, M. quinquenervia trees were randomly selected and herbivore presence or absence was determined by searching canopy vegetation during a Pratt et al 2006;Pratt et al 2008;Pratt and Arakelian 2011). Dispersal pathways radiating from south Florida to surrounding regions include natural as well as human-mediated mechanisms.…”

An underlying assumption of classical biological control implies that intentionally introduced natural enemies will remain within the boundaries that delineate the program's area of implementation. A weed biological control program targeting Melaleuca quinquenervia in Florida, USA has resulted in the release and establishment of Oxyops vitiosa and Boreioglycaspis melaleucae. An international survey of M. quinquenervia populations in 13 other states or countries where the insects have not been intentionally introduced was initiated to monitor the long range dispersal of O. vitiosa and B. melaleucae beyond the herbivores' intended geographic range (Florida). Surveys in 2006 resulted in the discovery of B. melaleucae within the canopies of several M. quinquenervia trees near San Juan, Puerto Rico. In 2007, O. vitiosa was observed on the island of New Providence in the Bahamas but neither herbivore was detected on nearby Grand Bahama or Andros islands. In 2009, B. melaleucae was observed attacking M. quinquenervia trees in Los Angeles, California (USA). The herbivores have not been detected on other surveyed M. quinquenervia populations in Cuba, Jamaica, Texas (USA), Costa Rica, Brazil, Hawaii (USA) or South Africa.There is no evidence to suggest that herbivore colonization of New Providence, Puerto Rico, or California was influenced by linear distance between Florida and the recipient M. quinquenervia stand. While the dispersal pathway(s) remains unknown, biological control agents were detected from 200 to [3500 km from their original release location (Florida) and at locations that have strong links via tourism and trade as indicated by the number of airline flights connecting south Florida with colonized tree populations. Implications of this unintended spread are discussed in relation to permeability of biogeographical barriers and risk assessment of biological control agents.

New and Simple Methods for Studying Hemipteran Stylets, Bacteriomes, and Salivary Sheaths in Host Plants

Many hemipteran insects are important agricultural pests because they cause direct feeding damage to their host plants and / or transmit plant disease agents including viruses and bacteria. Microscopic and behavioral studies on five hemipteran species from four families (Psyllidae, Aphididae, Cicadellidae, and Aleyrodidae) showed that their exuviae (molted skins) normally had either fully or partially extended stylets in a feeding-like position. In most cases these stylets were still partially embedded in their host plants after ecdysis, which indicated that plant-feeding hemipteran nymphs use their stylets to anchor themselves to host plants during molting. This phenomenon was used here to study the stylet length and ultrastructure in exuviae of various instars, which is normally more difficult in nymphs than in adults because of the fragility and smaller size of nymphs. Additionally, autofluorescence was used for studying the hemipteran salivary sheaths of nymphs and adults in their host plants. This method is based on fixation of free hand sections of plant parts on which hemipteran insects have been feeding, then mounting and examination of these sections with epifluorescence or confocal microscopy. No embedding, microtomy, or staining is necessary for this method that makes it much faster and simpler than other methods. Autofluorescence was also used to study the location and size of bacteriomes/mycetomes (organs containing symbionts) in hemipteran eggs and nymphs. The above methods were applied successfully with the Asian citrus psyllid (Diaphorina citri Kuwayama), melaleuca psyllid (Boreioglycaspis melaleucae Moore), oleander aphid (Aphis nerii Boyer de Fonscolomb), the whitefly Bemisia tabaci (Gennadius), and/or the glassy-winged sharpshooter leafhopper (Homalodisca vitripennis Germar).
