“…26 was detected in the headspace of healthy leaves and galls of B. spicata but showed a three times increase in galled tissues (from 13.5 ± 3.7 to 40.9 ± 4.4). The induction of galls in Silphium lacinatum L. (Asteraceae) by Antistrophus rufus (Hymenoptera: Cynipidaea) was recently associated to changes in enantiomeric ratios of a-and β-pinene which act as oviposition signals.…”

“…25 Schinus polygamus presents foliar galls induced by an unidentified psyllid species probably belonging to the genera Calophya. 26 These small conical galls were found dispersed on the leaf blade, which maintains portions of healthy tissue (Figure1). Both species are native of Brazil and belong to plant genera which present volatile organic compounds (VOC) 18,24 that can act as mediators in the interactions between these plant species and some associated herbivores.…”

“…6,11 Psyllids are very tiny species and are obligatory parasites, i.e., need the plant hosts in the majority of its life cycle. 26 Traditional chemoecological tests are not appropriate to investigate these galling species. The use of HS-SPME proved to be a rapid and easy analytical tool, giving access to important information related to signaling mechanisms of this kind of plant-insect interaction.…”

Baccharis spicata (Asteraceae) e Schinus polygamus (Anacardiaceae) são plantas nativas do Rio Grande do Sul e são hospedeiras de dois psilídeos galhadores (Hemiptera, Psyllidae) ainda não identificados. As duas plantas em estudo produzem óleo essencial e seus compostos voláteis podem ter um importante papel na interação inseto-planta. A extração e análise dos voláteis das folhas, folhas galhadas e galhas foram realizadas por microextração em fase sólida no modo "headspace" e por cromatografia gasosa com detector de espectrometria de massas. Verificou-se que a composição do "headspace" das galhas de B. spicata e S. polygamus é diferente daquela do "headspace" das folhas sadias. A principal alteração observada foi o aumento da contribuição de monoterpenos no "headspace" das galhas comparativamente ao que se verificou nos tecidos saudáveis. Algumas mudanças também foram observadas na produção de voláteis verdes, em ambas as espécies, mas especialmente na S. polygamus. O possível papel ecológico desses compostos químicos também é discutido.Baccharis spicata (Asteraceae) and Schinus polygamus (Anacardiaceae) are plants native from Rio Grande do Sul and are hosts of two unidentified galling psyllids (Hemiptera, Psyllidae). Both plant species produce essential oil and their volatile compounds play an important role related to this kind of plant-insect interaction. Extraction and analysis of volatiles produced by leaves, galled leaves and galls were performed using headspace solid phase microextraction and gas chromatography coupled to mass spectrometry detector. Composition of the headspace of B. spicata and S. polygamus galls showed a significant change in their volatile profile when compared to healthy leaves. These changes were mainly related to a higher production of monoterpenes in galled tissue, compared to what was found in healthy samples. Some changes on the production of green leaf volatiles were also observed in both plant species, especially in S. polygamus. The possible ecological role of these chemical changes was discussed. Keywords: galls, leaves, Baccharis spicata, Schinus polygamus, headspace solid phase microextraction IntroductionGalls are the result of histological alterations in plant organs, mainly hypertrophy and hyperplasy, caused by the activity of an inductor which can be virus, bacteria, nematodes, insects and other plants. These organisms can interfere with the normal development of cells and tissues leading to several physiological and morphological changes. Gall-inducing insects (insect gallmakers) are masters in the art of beguiling or compelling the host plant to provide food and shelter with a minimum expenditure of effort on their part and galls induced by insect are one of most diverse plant galls.1 Galls are found on all plant organs, such as flowers, leaves, stems and roots. They provide food and shelter to the inducer which lives in a microenvironment relatively safe from natural enemies.2 The leaf galls are variable in form and occur in the majority of plant hosts. 2Plant volatil...

Four new neotropical Trioza species associated with Loranthaceae (Santalales) and comments on mistletoe inhabiting psyllids (Hemiptera, Psylloidea)

Four new Trioza species associated with mistletoes are described, diagnosed and illustrated from Brazil and Chile. They are monophagous on the Loranthaceae Struthanthus uraguensis (Trioza struthanthi sp. n.), Tripodanthus acutifolius (Trioza tripodanthi sp. n.) and narrowly oligophagous on Tristerix spp. (Trioza tristericis sp. n.). For a fourth species (Trioza vagata sp. n.) host information is unavailable but its association with mistletoes is likely. The four species form a putative monophyletic group, together with three North American species (Trioza acuminata Tuthill, T. incidata Tuthill and T. phorodendrae Tuthill), based on the apically incised paramere, the highly modified valvulae of the female ovipositor and the host association with mistletoes. T. acuminata stat. n. from California is raised to species rank (originally described as subspecies of T. phorodendrae). The Trioza struthanthi-group is diagnosed and a key for the identification of its constituent members is provided. New host data are provided for Calophya sp. from Brazil as well as for Notophorina fusca Burckhardt and Zonopelma australis Burckhardt from Chile. Host plant and biogeographical patterns of mistletoe feeding psyllids around the world are briefly discussed.

“…The number of host-plants on which the immature to adult life cycle is completed is usually restricted to one or a few closely related plant species, hence the reputation of psyllids as highly host specific. In addition, closely related psyllid species tend to develop on closely related plant species (Burckhardt & Basset 2000;Percy et al 2004). Psyllids represent, therefore, a potentially ideal model group for addressing evolutionary aspects of insect-plant relationships (Hodkinson 1974(Hodkinson , 2009Hollis 1987;Hollis & Broomfield 1989;Percy 2003;Percy et al 2004;Burckhardt 2005).…”

Response of summerform pear psylla (Hemiptera: Psyllidae) to male- and female-produced odors

We examined the role of chemical signals in sex attraction of pear psylla, Cacopsylla pyricola (Förster), assessing the response of summerform male and female psyllids to male- and female-produced volatile chemicals. Male psyllids were attracted to odors from live females and pentane extracts of females. Extracts of females were as attractive to males as live females, suggesting that the female-produced volatile chemicals responsible for male attraction might be isolated by extracting females with pentane. Females were not attracted to odorants from live females and tended to avoid odorants from extracts of females. Furthermore, summerform males and females were not attracted or repelled by male-produced odorants from live males or extracts of males. Results of olfactometer assays using male summerform C. pyricola are consistent with results from earlier studies with the winterform morphotype of this species.
