Rhynchophorus ferrugineus, also known as the red palm weevil, is regarded as the major pest of palm trees. Although studies of the microbiota associated with this species have been performed in recent years, little attention has been dedicated to the influence of the diet in shaping the host bacterial community. Here, we investigated the influence of food sources (i.e. palm tissues vs apple based substrate) on the microbial diversity associated with RPW, which was compared with the microbiota associated with wild individuals of the sister species Rhynchophorus vulneratus. The bacterial characterization was performed using a culture independent approach, i.e. the 16S rRNA pyrotag, and a culture dependent approach for a subset of the samples, in order to obtain bacterial isolates from RPW tissues. The bacterial community appeared significantly influenced by diet. Proteobacteria resulted to be the most abundant clade and was present in all the specimens of the three examined weevil groups. Within Proteobacteria, Enterobacteriaceae were identified in all the organs analysed, including hemolymph and reproductive organs. The apple-fed RPWs and the wild R. vulneratus showed a second dominant taxon within Firmicutes that was scarcely present in the microbiota associated with palm-fed RPWs. A comparative analysis on the bacteria associated with the palm tissues highlighted that 12 bacterial genera out of the 13 identified in the plant tissues were also present in weevils, thus indicating that palm tissues may present a source for bacterial acquisition.

“…The reason given for the negative decision by USDA APHIS was that ''… this insect may negatively impact a United States crop plant (safflower)'' and was likely based on data showing that under no-choice conditions, the weevil's fundamental host range included safflower (Carthamus tinctorius L.) (Smith 2007), a crop plant grown for oil production. However, in tests examining the realized host range of the weevil, safflower was not attacked during five open-field experiments (three included in the petition and two conducted subsequently (Cristofaro et al 2013;Rector et al 2010;Smith et al 2006). In addition, C. basicorne has never been reported from safflower in their shared native Eurasian range (Cristofaro et al 2013).…”

In this paper, we describe five successful classical biological weed control agents released in the United States. For each of the five arthropod species, we compared data from prerelease studies that experimentally predicted the agent's host range with data collected postrelease. In general, experimental host range data accurately predicted or overestimated risks to nontarget plants. We compare the five cases with insects recently denied for introduction in the United States and conclude that none of the discussed agents would likely be approved if they were petitioned today. Three agents would be rejected because they potentially could attack economic plants, and two because of potential attack on threatened or endangered plants. All five biocontrol agents have contributed significantly to the successful management of major weeds with no or minimal environmental risk. We believe that the United States may miss opportunities for sustainable and environmentally benign management of weeds using biological control if the regulatory framework only considers the risks of agents as potential plant pests and treats any host-range data regarding economic or threatened and endangered species as a binary decision (i.e., mandates rejection if there is any chance of feeding or development). As a way forward we propose the following: (1) the addition of risk and benefit analyses at the habitat level with a clear ranking of decision-making criteria as part of the U.S. Department of Agriculture Animal and Plant Health Inspection Service Technical Advisory Group's evaluation process of biocontrol agents; (2) recognition of the primacy of realized host range data for potential agents that considers the insect's host selection behavior instead of emphasizing fundamental host range data during release evaluations, and (3) development of formalized postrelease monitoring of target and nontarget species as part of the release permit. These recommendations may initially be advanced through reassessment of current policies but may in the longer term require the implementation of dedicated biocontrol legislation.

“…They found that 54% of the YST but none of the 1021 safflower plants were attacked by the weevil. In addition, Rector et al () in a field experiment in France found that C. basicorne attacked yellow starthistle and cornflower but not safflower (Antonini et al , ). The rosette weevil is not known to attack safflower in its Palearctic range (Alonso‐Zarazaga, ; Wanat, ) and the host specificity data suggest that it is highly stenophagous (Smith, ).…”

“…Field observations (Uygur et al , ) and modelling analysis (Gutierrez et al , ) suggest that natural enemies killing whole plants before seed maturation and/or reducing the ability of surviving plants to compensate for feeding damage with reduced seed production are required for successful control (see below). The weevil Ceratapion basicorne (Illiger) (Coleoptera; Brentidae) attacks the rosette stage of YST throughout most of its range in the Mediterranean Basin (Alonso‐Zarazaga, ; Antonini et al , ) and has some of requisite attributes: infestation levels range from 25% to 100% (Uygur et al , ; Smith et al , ) and it is highly host specific (Smith et al , ; Smith, , ; Rector et al , ; Cristofaro et al , ). A release permit application for C. basicorne for North America was submitted to USDA‐APHIS (U.S. Department of Agriculture's Animal and Plant Health Inspection Service) on 26 January 2006 (Smith, ), although approval has not been granted because of concerns about possible risk to safflower crops ( Carthamus tinctorius ) and the ornamental cornflower ( Centaurea cyanus ) that are of Palearctic origin (Hinz et al , ; L. Smith, personal communication).…”

Assessing the biological control of yellow starthistle (Centaurea solstitialis L): prospective analysis of the impact of the rosette weevil (Ceratapion basicorne (Illiger))

1 Yellow starthistle (Centaurea solstitialis L) (YST) is an invasive weed native to the Mediterranean region with a geographical centre of diversity in Turkey. It is widely established in Chile, Australia, and western North America. It arrived in California as a contaminant in alfalfa seed in 1859 and, by 2002, had infested >7.7 million hectares in the U.S.A. 2 Biological control of YST using capitula feeding weevils, picture wing flies and a foliar rust pathogen has been ongoing in the western U.S.A. for more than three decades with limited success. Modelling and field research suggest natural enemies that kill whole plants and/or reduce seed production of survivors are good candidates for successful biological control. A candidate species with some of these attributes is the rosette weevil Ceratapion basicorne (Illiger). 3 In the present study, a model of the rosette weevil is added to an extant system model of YST and its capitula feeding natural enemies and, in a GIS context, is used to assess YST control in the Palearctic region and the weevil's potential impact on YST in western U.S.A. 4 The results obtained suggest densities of mature YST plants in western U.S.A. would be reduced by 70-80% in many areas.
