Very glad to hear you're busily setting yourself nature challenges for 2021. The authors received no funding for this work. Within Diprionidae, the subfamily Monocteninae comes out as paraphyletic, as the representative of Augomonoctenus is separated as the most basal representative of the family. Conventional insecticides such as malathion are also effective. Stephan M. Blank, Katja Kramp, Xyela davidsmithi (Hymenoptera, Xyelidae), a New Pine Catkin Sawfly with an Unusual Host Association from the Sierra Nevada , Proceedings of the Entomological Society of Washington, 10.4289/0013-8797.119.SpecialIssue.703, 119, sp1, (703-717), (2017). The eggs hatch and the pine catkin sawfly larvae feed on the male cones (or catkin) as they grow out. (2012), whereas it has been recovered outside of Tenthredinidae in other studies (Schulmeister, 2003; Heraty et al., 2011; Ronquist et al., 2012a) or changing position among different analyses (Schulmeister et al., 2002). Balkan pine (Pinus peuce) cones. Many thanks to Dave Cheung for the use of his Insect and Disease images. Within Tenthredinoidea, the monophyly of Tenthredinidae is unclear with regard to Cimbicidae and Diprionidae, largely because the supposed tenthredinid genus Athalia and its close relatives introduce great uncertainty (Schulmeister, 2003; Sharkey et al., 2012; Klopfstein et al., 2013). Complete mitochondrial genome sequence of Zheng BY, Li ZK, Li XF, Zhu JC, Sharkey M, Tang P, Chen XX. You may see different varieties on leaves, shoots and roots. Microsatellites are widely used as powerful markers in population genetics because of their ability to access recent genetic variation and to resolve subtle population genetic structures. Voucher specimens were provided by, and are stored at, many different institutions (Appendix S1). However, based on the well‐supported results from the BI and ML analyses, Xyelidae was used for rooting trees in subsequent analyses, in which we included only hymenopteran taxa. The resolution within this clade is improved and strengthened by the inclusion of third codon positions, an effect of better sampling and possibly younger diversification age among the larger tenthredinoid groups than within the Unicalcarida (see Ronquist et al., 2012a). The first mitogenomes of the superfamily Pamphilioidea (Hymenoptera: Symphyta): Mitogenome architecture and phylogenetic inference. 18.0% missing data) (Table 2). | Tracking of Host Defenses and Phylogeny During the Radiation of Neotropical Inga-Feeding Sawflies (Hymenoptera; Argidae). She deposits a single egg into each slit and several eggs in a needle.The larvae are caterpillar-like with six or more pairs of prolegs on the abdomen. Blow Fly. Conifer Sawfly's Habitat. Figure 1. In August to September, the adult European pine sawflies emerge from their cocoons to mate and lay eggs. Relationships within Tenthredinoidea are shown as compressed (see Fig. But if you’re in the right place at the right time, something else might be dropping onto your . Larvae devour the needles of conifer trees. The contour lines in the maps indicate the spatial positions of genetic discontinuities. ... Yellow-Headed Spruce Sawfly – click here. Bayesian inference (BI) of the phylogeny was performed using MrBayes v3.2.1 (Ronquist et al., 2012b) on the BioPortal bioinformatics platform (Kumar et al., 2009). 2017;4303:103–121. Sawflies are one of the few insects in the wasp family that feed on plants. Enter your email address below and we will send you your username, If the address matches an existing account you will receive an email with instructions to retrieve your username, Saturation plots for gene fragments and their respective codon positions. Please check your email for instructions on resetting your password. With the exclusion of Heptamelus + Pseudoheptamelus and Athalia, the remaining taxa in the family Tenthredinidae form a strongly supported monophylum, in which Eriocampa ovata (hitherto in Allantinae) is the sister group to all others. 4; JF 99%, Appendix S5a). At first glance, you might think you've got a caterpillar problem, but sawflies have behavioral and morphological differences that differentiate them from Lepidopteran larvae. The microsatellites revealed a generally high gene flow between the populations, but also suggested a deep historical segregation into two genetic lineages. Native geographic location and habitat. Sixteen of those primer pairs were selected and implemented successfully to answer questions on the phylogeography and population genetics of X. concava. Susceptible to a number of pests including pine sawfly, pine needle scale and Zimmerman pine moth. (Hymenoptera:Tenthredinidae), a New Species from the Russian Far East These proposals have been debated since then (Smith, 1971; Pschorn‐Walcher and Altenhofer, 1989; Goulet, 1992; Taeger et al., 2010; Leppänen et al., 2012). In contrast, our phylogenetic hypothesis based on the 12 + CAD3 + GLN3_hym data set fixes Pamphilioidea between two highly supported branches. Well it could be pine catkin sawfly larvae (Xyela). Pine trees produce male cones, which shed … These species form the X. bakeri group, which is considered to be the sister clade of the Eurasian X. julii group. The traditional subfamily Heterarthrinae is polyphyletic, and both of its two subgroups are found within Blennocampinae. (2012) recover it as paraphyletic, we find a monophyletic Blasticotomidae (consisting of internal fern feeders) as the earliest‐diverging extant family of Tenthredinoidea. Climate change and forest plagues: assessing current and future impacts of diprionid sawflies on the pine forests of north-western Mexico. Clipboard, Search History, and several other advanced features are temporarily unavailable. A yellow glaze coats everything outside and many are taking their allergy medicine religiously. Gardeners most often encounter sawflies when the larvae feed on their plants. Fall Cankerworm – click here. Ronquist et al. Most of the new gene fragments were possible to amplify with selected primers for most taxa, but GLN and GS were particularily difficult for Xyelidae, Pamphiliidae, and some apocritan taxa (see Appendix S1). The larch sawflies are found on various species of larch as well as Tamarack. Additionally, we re‐ran the MP analyses with 10 iterations of drifting and ratchet for each replication, and until the shortest tree was found 100 times. Proceedings of the Zoological Institute RAS. oviposting on ponderosa pine. Sites within each gene were partitioned by placing the slower‐evolving first and second codon positions in one partition (p12) and the faster‐evolving third positions in their own (p3); hence there were 18 data partitions in the full data sets. TPI was slightly better than NAK and GS, but was also the shortest gene fragment utilized in this study. In sequence after the divergence of Xyelidae is a branching event separating Pamphilioidea (with a strongly supported pairing of Megalodontesidae and Pamphiliidae) from Tenthredinoidea + Unicalcarida (Fig. One of nature’s unique creatures is the European pine sawfly. This arrangement is highly supported, but with weaker support from the 12_all (PP 0.91 and CF 51%, Appendix S4a; JF < 50%, Appendix S5a) and 12_hym analyses (PP 0.96 and CF 52%, Appendix S4b; JF < 50%, Appendix S5b). Analcellicampa danfengensis The best sampled gene fragment was PGD, which included over 91% of the potentially available nucleotides, in contrast to GS with a completion proportion slightly below 70%. Life Cycle - European Pine Sawfly They may feed on short leaf and Virginia pines, but usually damage is not heavy. New fossils from China elucidating the phylogeny of Praesiricidae (Insecta: Hymenoptera). In addition, we more than tripled the taxon coverage across the symphytan grade, introducing representatives for many previously unsampled lineages. (Hymenoptera, Xyelidae), a New Pine Catkin Sawfly with an Unusual Host Association from the Sierra Nevada Larvae of … We sampled 167 representatives from all 14 families belonging to the symphytan grade of Hymenoptera. Although this might be an effect of sparse sampling of apocritan taxa, the pattern of low resolution in this part of the tree is shared with more Apocrita‐oriented phylogenetic analyses with denser representation of vespinan lineages (e.g. Sampling of more Eriocampa species as well as putative relatives (Eriocampopsis, Dimorphopteryx, Pseudosiobla, Conaspidia, and Armitarsus) will be crucial to fully stabilize its position within Tenthredinidae. Therefore our main analyses were performed using the reduced data sets (12_all, 12_hym and 12 + CAD3 + GLN3_hym) described above. by eye, direct optimization, based on secondary structure, or with different alignment software), usually with different results presented thereafter (Heraty et al., 2011; Klopfstein et al., 2013). Anonymous. Maximum parsimony analyses of the 12_hym and 12 + CAD3 + GLN3_hym data sets (Appendix S5b,c) produced results that were more in line with the model‐based analyses, with monophyly of all symphytan families except Tenthredinidae, but with somewhat lesser support for superfamilies and larger groups. But it's the worm-like larva that causes damage to plants. Pine catkin sawflies emerge from the soil in February and lay eggs on the male cone buds of pine trees. 3). The sister‐group relationship between these families was recovered earlier in several analyses (Vilhelmsen, 1997; Schulmeister, 2003; Nyman et al., 2006; Davis et al., 2010; Leppänen et al., 2012; Sharkey et al., 2012), whereas others found a disjunct relationship between the two (Vilhelmsen, 2001; Schulmeister et al., 2002; Heraty et al., 2011; Ronquist et al., 2012a; Klopfstein et al., 2013). Pine trees produce male cones, which shed pollen, and female cones, which develop into pine cones. I firmly believe New Years Day acts as a ready, steady GO button for thousands of us, we can draw a line on what was and start afresh with sparkling eyes, keen ears and a renewed childlike enthusiasm - off into the wilds we go! Lighter shading indicates a higher probability of belonging to the genetic population), (B) BAPS (the area of each population is proportional to the number of specimens used) and (C) STRUCTURE. Presence of the canonical TTAGG insect telomeric repeat in the Tenthredinidae (Symphyta) suggests its ancestral nature in the order Hymenoptera. Dustin Kulanek, Stephan M. Blank, Katja Kramp, First microsatellite markers for the pine catkin sawfly Xyela concava (Hymenoptera, Xyelidae) and their application in phylogeography and population genetics , PeerJ, 10.7717/peerj.8010, 7, (e8010), (2019). Within Diprionidae, we find a paraphyletic Monocteninae, as Augomonoctenus is sister to Monoctenus + Diprioninae, with high support (PP 1 and CF 75%). Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors. Conifer sawflies (such as the loblolly pine sawfly, Neodiprion taedae linearis Ross) can occasionally cause serious injury to pines and other evergreens by feeding on foliage, tunneling into buds or boring into shoots. n. is described from the Sierra Nevada of California. The galls are caused by sawflies and other pests as well as bacteria and can look quite different depending on the pest causing them. The Hymenoptera is traditionally divided into two suborders: the “Symphyta”—sawflies and woodwasps—an ancestral, paraphyletic assemblage of broad‐waisted, mainly phytophagous lineages; and the derived and presumably monophyletic Apocrita, which is composed predominantly of parasitic and predatory species, all sharing the feature of a constricted wasp‐waist (Vilhelmsen and Turrisi, 2011). Within Tenthredinidae s.str. However, secondary herbivory has evolved in many apocritan subgroups in both “Parasitica” and Aculeata (Gauld and Bolton, 1988; Sharkey, 2007; Vilhelmsen and Turrisi, 2011). The nuclear sequences were supplemented with a 1078‐bp fragment from the mitochondrial COI gene.

Challenges in analysis and interpretation of microsatellite data for population genetic studies. We have … pine catkin sawfly larva. ... White Pine Weevil. The different colors represent the estimated posterior probabilities of the membership to each cluster. Life Cycle. Thus obtaining a full picture of subfamilial relationships within these two families will require further study. Retention of Core Meiotic Genes Across Diverse Hymenoptera. Adult female pine sawfly (Neodiprion spp.) Pyrethrin is a nerve agent that will absorb into the insect and kill by paralysis. The transition/transversion rate prior (tratiopr) was set to “beta(2.0,1.0)” to reflect a prior belief in a higher frequency of transitions than transversions. Diprion pini, often referred to as the Common Sawfly or Conifer Sawfly, is a pest of pine trees throughout much of Europe. Blister Beetle. Adult pine sawflies are seldom seen. Following these results, we propose that Heptamelus and Pseudoheptamelus should be raised to family level (Heptamelidae) from Tenthredinidae, thus not forcing the inclusion of the well defined families Diprionidae and Cimbicidae into Tenthredinidae. Gaps were treated as missing. However, in the combined analyses Z. turneri is positioned most basal within Argidae with high support. Within Tenthredinoidea, we have made several interesting discoveries, including a proposal to raise the selandriine (Tenthredinidae) tribe Heptamelini to family status, and to expand Blennocampinae to include Heterarthrinae as well as some allantine genera (here represented by Eusunoxa). The MP analysis including outgroups (Appendix S5a) suffered from problems of correctly rooting the Hymenoptera, evidently due to long‐branch attraction between apocritan (especially proctotrupomorphs) and outgroup taxa, and recovered a paraphyletic assemblage of apocritan taxa as the earliest diversification events within the order. In the analysis including non‐hymenopteran outgroups (12_all), Tenthredinoidea + Unicalcarida is supported only by the BI analysis, albeit weakly (PP 0.77, Appendix S4a).
