Mechanisms and consequences of flight polyphenisms in an outbreaking bark beetle species

AbstractThis paper reviews the literature on the identification of 3-methylcyclohex-2-en-1-one (MCH) as the antiaggregation pheromone of the Douglas-fir beetle (Dendroctonus pseudotsugae Hopkins) (Coleoptera: Curculionidae) and the development of successful management applications using the pheromone. Previously unpublished data from two studies on novel uses of MCH are included. The successful development of antiaggregation pheromone-based treatments for the Douglas-fir beetle is discussed in relation to efforts to develop similar treatments for other bark beetle species, and opportunities for future research on MCH and the Douglas-fir beetle are suggested.

A previously unknown bark beetle species, Cryphalus eriobotryae sp. nov. Johnson, 2019 has emerged as a lethal pest of loquat (Eriobotrya japonica) in China. The description of new species has been provided. The new species is distinguished from the other Cryphalus by the weakly aciculate frons, by the antennae, with unevenly spaced procurved sutures, by the short pronotal disc, with hair-like setae, and by the widely spaced mesocoxae. The survey of plantation records from around Suzhou suggests that this beetle was introduced from another area not long before 2017. In the surveyed loquat plantation in 2018, 20–90% of trees showed signs of infestation, and 5% were killed in 2018, resulting in the death of over 1000 trees. Outbreaks of the apparently loquat-specific Cryphalus eriobotryae can be diagnosed by hundreds of cankers on the trunk, and wilted foliage. This pest is of concern as a loquat plantation pest and as a pest of fruit production and ornamental trees within Suzhou, and globally.

Feeding Aggregation

AbstractComparative gas chromatographic analyses of volatiles generated by Ips indicate the presence of cis- and trans-verbenol in hindguts of the 12 species investigated. The biosynthesis of verbenol does not require feeding, but instead results from the insect’s contact with oleoresin. Ipsdienol is the most frequently occurring pheromone in Ips species after feeding. Aggregation of these bark beetles appears to be regulated by two distinct functional types of pheromones, i.e. contact pheromones, produced and/or released upon contact with new host material, and frass pheromones, which require actual feeding in the new host’s tissues. The aggregation of aggressive bark beetle species seems to be largely dependent on contact pheromones, whereas the host’s susceptibility to feeding is indicated by the release of frass pheromones.

На основе литературных материалов и результатов собственных исследований авторов проанализированы короеды рода Ips. Отмечается, что в мировой фауне зарегистрировано 37 видов коро- едов данного рода, в том числе восемь распространено на территории Российской Федерации. короеды данного рода повреждают флоэму и камбий, как правило, у ослабленных и отмирающих деревьев. Не- редко они заселяют поваленные ветром деревья и неокоренную лесопродукцию. В то же время в экстре- мальные по погодным условиям годы или после стихийных бедствий (засуха, штормовой ветер и др.) численность короедов резко возрастает, и они приводят к гибели не только отдельные жизнеспособные деревья, но и древостои. кроме того, короеды являются переносчиками спор грибов, приводящих к де- струкции древесины. В работе приведен перечень видов короедов рода Ips, дано описание биологии не- которых видов и рекомендации по недопущению их распространения за пределы естественного ареала. Ключевые слова: короеды, Ips, биологические особенности, виды, карантин, вредоносность. Финансирование. Работа выполнена в рамках темы FEUG – 2020 – 0013 «Экологические аспекты рационального природопользования». Bark beetles of the Ips genus were analyzed on the barks of literature materials and the results of the authors own research. It is noted that 37 species of bark beetles of this genus have been recorded in the wored fauna, including 8 common on the territory of the Russian Federation. Bark beetles of this genus damage their cambium, as a rule in weakened and dying trees. Often they inhabit trees felled by the wind and forest product uncovered with bark. However, in extreme weather years or after natural disasters (drought, storm, wind and other) number of bark beetles increases shar ply and they this results in the death not only individual viable trees, but also the whole stand. In addition, bark beetles are carriers of fungal spores, leading to the destruction of wood. The work provides a list of bark beetles species of Ips genus, the description of the biology of some species is given, as well as recommendations for preventing their spreading outside the natural range.

Phylogenetic Implications

Many bark beetles of the subfamily Scolytinae are the most economically important insect pests of coniferous forests worldwide. In this study, we sequenced the mitochondrial genomes of eight bark beetle species, including Dendroctonus micans, Orthotomicus erosus, Polygraphus poligraphus, Dryocoetes hectographus, Ips nitidus, Ips typographus, Ips subelongatus, and Ips hauseri, to examine their structural characteristics and determine their phylogenetic relationships. We also used previously published mitochondrial genome sequence data from other Scolytinae species to identify and localize the eight species studied within the bark beetle phylogeny. Their gene arrangement matched the presumed ancestral pattern of these bark beetles. Start and stop codon usage, amino acid abundance, and the relative codon usage frequencies were conserved among bark beetles. Genetic distances between species ranged from 0.037 to 0.418, and evolutionary rates of protein-coding genes ranged from 0.07 for COI to 0.69 for ND2. Our results shed light on the phylogenetic relationships and taxonomic status of several bark beetles in the subfamily Scolytinae and highlight the need for further sequencing analyses and taxonomic revisions in additional bark beetle species.

A new Oodinychus Berlese, 1917 species, O. scolytana sp. nov., was discovered and described from the galleries of bark beetles Polygraphus proximus Blandford from two different parts of Asian Russia. New associations are given for the trematurid mites and bark beetle species. Three bark beetle associated species from the Trichouropoda ovalis-group are moved into the genus Oodinychus as O. hirsuta (Hirschmann, 1972) comb. nov., O. rafalski (Wiśniewski & Hirschmann, 1984) comb. nov. and O. wilkinsoni (Hirschmann &Wiśniewski, 1986) comb. nov. Also, Oodinychus egypticus Abo-Shnaf, El-Bishlawy & Allam, 2018 is transferred to the genus Nenteria Oudemans, 1915.
