First record of \u3ci\u3eAncognatha erythrodera\u3c/i\u3e (Blanchard, 1846) (Coleoptera: Scarabaeidae: Dynastinae: Cyclocephalini) in the altiplano of Chile

The presence of Ancognatha erythrodera (Blanchard, 1846) (Coleoptera: Scarabaeidae) is confirmed for the first time in Chile based on male and female specimens collected in the extreme north of the country. This is the second species of Ancognatha Erichson, 1847 recorded in Chile. Morphological characters, illustrations of male genitalia, male and female habitus photographs of this species, and additional records in Argentina and Bolivia are provided. A map with the collection sites and montane habitats photograph in Chile are included. The Dynastinae (Coleoptera: Scarabaeidae) that occur in Chile were comprehensively revised by Ratcliffe et al. (2021), who recorded nine species in six genera. One of these genera, Ancognatha Erichson, 1847, includes 23 valid species found from the southwestern United States (Arizona and New Mexico) to northern Argentina, Chile, and Bolivia (Mondaca 2016; Moore et al. 2018a; Paucar-Cabrera and Ratcliffe 2018; Ratcliffe et al. 2021). In this note, we report the first record of Ancognatha erythrodera (Blanchard, 1846) in Chile, based on specimens collected in the altiplanic locality of Visviri, Región de Arica y Parinacota. Previously, Ancognatha erythrodera was recorded for the Andes of southern Peru, Bolivia, and northwestern Argentina (Moore et al. 2018b). This new record corresponds to the natural distribution of this species on both sides of the Andes mountain range, which is not surprising due to the similarity of habitats in neighboring localities in Peru, Bolivia, and Argentina

\u3ci\u3eSybra alternans\u3c/i\u3e (Wiedemann) (Lamiinae: Apomecynini): an Asian cerambycid established on Easter Island, Chile

Seven specimens of Sybra alternans (Wiedemann) (Cerambycidae: Lamiinae: Apomecynini) were captured with a UV light trap and by beating branches of trees in the urban area of Easter Island (Chile) during 2011–2016, representing the fi rst record of the species in this Chilean insular territory, but not continental Chile. Sybra alternans is native to Southeast Asia and has been introduced accidentally to Hawaii and Florida in the United States of America. Data are presented from the literature on this species’ distribution, host plants, and biological information. Resumen.

The conditions of average temperatures and annual precipitations for the establishment of the species are analyzed.Se registra por primera vez la presencia del Ptinidae Ozognathus cornutus en Chile, basado en seis ejemplares encontrados en la ciudad de Santiago. El nuevo registro de esta especie, originaria de América del Norte, se suma a intercepciones registradas a partir de la última década del siglo XX en el norte de África, Europa y Nueva Zelandia. Se analizan las condiciones de temperatura promedio y precipitaciones anuales para el establecimiento de la especie

Detección de Leucoptera sinuella (Reutti) (Lepidoptera: Lyonetiidae) en Chile, con la identificación de algunos parasitoides asociados

En marzo del 2015 el Servicio Agrícola y Ganadero (SAG), a través de actividades de vigilancia forestal, detectó por primera vez en Chile la presencia de Leucoptera sinuella (Reutti), atacando follaje de álamos (Populus spp., Salicaceae), en la comuna de Talagante (Región Metropolitana de Santiago). Actividades de prospección desarrolladas por el SAG han determinado que este microlepidóptero se encuentra distribuido en diversas comunas de las regiones de Valparaíso, Metropolitana de Santiago, Libertador General Bernardo O’Higgins, Maule, Ñuble y Biobío. Adicionalmente, fueron identificadas siete especies de microhimenópteros parasitoides asociados a L. sinuella, pertenecientes a las familias Eulophidae (6 especies) y Chalcididae (1 especie)

Expert-based development of a generic HACCP-based risk management system to prevent critical negative energy balance in dairy herds

The objective of this study was to develop a generic risk management system based on the Hazard Analysis and Critical Control Point (HACCP) principles for the prevention of critical negative energy balance (NEB) in dairy herds using an expert panel approach. In addition, we discuss the advantages and limitations of the system in terms of implementation in the individual dairy herd. For the expert panel, we invited 30 researchers and advisors with expertise in the field of dairy cow feeding and/or health management from eight European regions. They were invited to a Delphi-based set-up that included three inter-correlated questionnaires in which they were asked to suggest risk factors for critical NEB and to score these based on 'effect' and 'probability'. Finally, the experts were asked to suggest critical control points (CCPs) specified by alarm values, monitoring frequency and corrective actions related to the most relevant risk factors in an operational farm setting. A total of 12 experts (40 %) completed all three questionnaires. Of these 12 experts, seven were researchers and five were advisors and in total they represented seven out of the eight European regions addressed in the questionnaire study. When asking for suggestions on risk factors and CCPs, these were formulated as 'open questions', and the experts' suggestions were numerous and overlapping. The suggestions were merged via a process of linguistic editing in order to eliminate doublets. The editing process revealed that the experts provided a total of 34 CCPs for the 11 risk factors they scored as most important. The consensus among experts was relatively high when scoring the most important risk factors, while there were more diverse suggestions of CCPs with specification of alarm values and corrective actions. We therefore concluded that the expert panel approach only partly succeeded in developing a generic HACCP for critical NEB in dairy cows. We recommend that the output of this paper is used to inform key areas for implementation on the individual dairy farm by local farm teams including farmers and their advisors, who together can conduct herd-specific risk factor profiling, organise the ongoing monitoring of herd-specific CCPs, as well as implement corrective actions when CCP alarm values are exceeded

Genome-wide association for milk production and lactation curve parameters in Holstein dairy cows

The aim of this study was to identify genomic regions associated with 305-day milk yield and lactation curve parameters on primiparous (n = 9,910) and multiparous (n = 11,158) Holstein cows. The SNP solutions were estimated using a weighted single-step genomic BLUP approach and imputed high-density panel (777k) genotypes. The proportion of genetic variance explained by windows of 50 consecutive SNP (with an average of 165 Kb) was calculated, and regions that accounted for more than 0.50% of the variance were used to search for candidate genes. Estimated heritabilities were 0.37, 0.34, 0.17, 0.12, 0.30 and 0.19, respectively, for 305-day milk yield, peak yield, peak time, ramp, scale and decay for primiparous cows. Genetic correlations of 305-day milk yield with peak yield, peak time, ramp, scale and decay in primiparous cows were 0.99, 0.63, 0.20, 0.97 and -0.52, respectively. The results identified three windows on BTA14 associated with 305-day milk yield and the parameters of lactation curve in primi- and multiparous cows. Previously proposed candidate genes for milk yield supported by this work include GRINA, CYHR1, FOXH1, TONSL, PPP1R16A, ARHGAP39, MAF1, OPLAH and MROH1, whereas newly identified candidate genes are MIR2308, ZNF7, ZNF34, SLURP1, MAFA and KIFC2 (BTA14). The protein lipidation biological process term, which plays a key role in controlling protein localization and function, was identified as the most important term enriched by the identified genes
