Specificity of the beetle-fungus relationship has rarely been examined, and simple vertical transmission of a specific fungal cultivar by each beetle species is often assumed in literature. We report repeated evolution of fungal crop stealing, termed mycocleptism, among ambrosia beetles. The mycocleptic species seek brood galleries of other species, and exploit their established fungal gardens by tunneling through the ambient mycelium-laden wood. Instead of carrying their own fungal sybmbionts, mycocleptae depend on adopting the fungal assemblages of their host species, as shown by an analysis of fungal DNA from beetle galleries. The evidence for widespread horizontal exchange of fungi between beetles challenges the traditional concept of ambrosia fungi as species-specific symbionts. Fungus stealing appears to be an evolutionarily successful strategy. It evolved independently in several beetle clades, two of which have radiated, and at least one case was accompanied by a loss of the beetles' fungus-transporting organs. We demonstrate this using the first robust phylogeny of one of the world's largest group of ambrosia beetles, Xyleborini.10aXyleborini1 aHulcr, Jiri1 aCognato, Anthony, I.  uhttps://weevil.myspecies.info/repeated-evolution-crop-theft-fungus-farming-ambrosia-beetles05186nas a2200589   4500008004100000020002500041245015100066210006900217260001000286300000900296490000900305520329900314653003203613653003203645653002903677653002303706653001003729653002303739653002203762653001703784653002803801653001803829653002203847653002403869653001503893653002703908653002403935653002103959653002303980653002704003653002804030653002704058653002204085653002604107653001504133653002104148653002304169653002404192653002304216653001504239653002304254653002304277653002304300653001604323653002304339653002704362653001504389653002304404100001604427700001804443856013504461       2010                        eng d  a1175-5326; 1175-533400aNew genera of Palaeotropical Xyleborini (Coleoptera: Curculionidae: Scolytinae) based on congruence between morphological and molecular characters0 aNew genera of Palaeotropical Xyleborini Coleoptera Curculionidae  c8 Dec  a1-330 v27173 aAs part of an ongoing genus-level revision of Xyleborini (Coleoptera, Curculionidae: Scolytinae), we combined a recent molecular phylogenetic analysis of the tribe (Cognato et al., 2011) with extensive analysis of morphological characters (over 44,000 representatives of 281 putative species of Xyleborini examined, including 264 types).

They also represent the most invasive scolytines in North America. Despite economic concerns and biological curiosity with this group, a comprehensive understanding of generic boundaries and the evolutionary relationship among species is lacking. In this study, we include 155 xyleborine species representing 23 genera in parsimony and Bayesian analyses using 3925 nucleotides from mitochondrial (COI) and nuclear genomes (28S, ArgK, CAD, EF-1a) and 39 morphological characters. The phylogenies resulting from the parsimony analyses, which treated gap positions either as missing or fifth character states, and the Bayesian analysis were generally similar. Clades with high support or posterior probabilities were found in all trees, while those with low support were not recovered by all analyses. Fourteen of the 23 genera were monophyletic although not all relationships among the genera were resolved. We show monophyly of several species groups associated with particular morphological and biological characters and suggest recognition of these groups as genera. Most interesting was the monophyly of South and Central American species representing several genera. This finding suggests recent and fast radiation of xyleborines in the New World accompanied by morphological and biological diversification.10aXyleborini1 aCognato, Anthony, I.1 aHulcr, Jiri1 aDole, Stephanie, A.1 aJordal, Bjarte, H.  uhttps://weevil.myspecies.info/phylogeny-haplo-diploid-fungus-growing-ambrosia-beetles-curculionidae-scolytinae-xyleborini-inferred02236nas a2200145   4500008004100000245011200041210006900153260000900222300001200231490000700243520172700250653001501977100002901992856006902021       2010                        eng d00aObservations on sex ratio and behavior of males in Xyleborinus saxesenii Ratzeburg (Scolytinae, Coleoptera)0 aObservations on sex ratio and behavior of males in Xyleborinus s  c2010  a253-2670 v563 aStrongly female-biased sex ratios are typical for the fungal feeding haplodiploid Xyleborini (Scolytinae, Coleoptera), and are a result of inbreeding and local mate competition (LMC). These ambrosia beetles are hardly ever found outside of trees, and thus male frequency and behavior have not been addressed in any empirical studies to date. In fact, for most species the males remain undescribed. Data on sex ratios and male behavior could, however, provide important insights into the Xyleborini's mating system and the evolution of inbreeding and LMC in general. In this study, I used in vitro rearing methods to obtain the first observational data on sex ratio, male production, male and female dispersal, and mating behavior in a xyleborine ambrosia beetle. Females of Xyleborinus saxesenii Ratzeburg produced between 0 and 3 sons per brood, and the absence of males was relatively independent of the number of daughters to be fertilized and the maternal brood sex ratio. Both conformed to a strict LMC strategy with a relatively precise and constant number of males. If males were present they eclosed just before the first females dispersed, and stayed in the gallery until all female offspring had matured. They constantly wandered through the gallery system, presumably in search of unfertilized females, and attempted to mate with larvae, other males, and females of all ages. Copulations, however, only occurred with immature females. From galleries with males, nearly all females dispersed fertilized. Only a few left the natal gallery without being fertilized, and subsequently went on to produce large and solely male broods. If broods were male-less, dispersing females always failed to found new galleries.10aXyleborini1 aBiedermann, Peter, H.
