One modelling based on individual tree level and two mortality modelling alternatives were evaluated: four survival probability equations and eight difference equations. The individual tree survival modelling considered a logistic model, is a linear combination of variables to individual tree at current time and the previous time as estimator, being the main variables the variation of the competition index and the variation of basal area growth between the current growth period and the previous growth period. The survival probability alternative used state variables of the stand (age, dominant height, average square diameter) as predictors, whereas the difference equations were adjusted according to age-based changes only. The models to stand levels showed better result than individual tree models, and in general, the mortality models based on difference equations presented better indicators of precision and parsimony.

The analytical method used was a structural equation modeling (SEM). Surveys were applied to 388 buyers in three traditional markets in Beijing, China. A confirmatory factor analysis was performed, which presented an adequate goodness of fit to accept the model, according to the literature, which confirmed the relations. The results showed, that perceived extrinsic quality and satisfaction are directly and significantly related to Chinese consumers’ intention to purchase fresh cherries. Additionally, an indirect and significant relationship was found between perceived intrinsic quality and purchase intention, through the mediating role of satisfaction. Highlights: Only the intrinsic perceived quality in fresh cherries is directly and significantly related to the satisfaction of Chinese consumers, generating indirect effects on the purchase intention through the mediating role of satisfaction, which is opposed to the results obtained in extrinsic perceived quality. The results obtained in this study determined that the intrinsic perceived quality does not present a direct and significant relationship with the purchase intention in fresh cherries, a result in conflict with that obtained in the extrinsic perceived quality. It was statistically demonstrated that intrinsic perceived quality has an indirect and significant influence on purchase intention through the mediating role of satisfaction; on the other hand, no indirect and significant influence was found between perceived extrinsic quality and purchase intention as a result of the mediating role of satisfaction. Satisfaction has a direct and significant relation on the purchase intention of Chinese consumers. The results of this research seem to be in line with the marketing initiatives developed by ASOEX, enhancing the attributes of intrinsic quality, color and size, and linking it to celebrations and traditions, through activities such as \"Super Cherries days\", \"Chilean Cherries dance\" and \"Cherries from Chile\", activities that have also been enhanced by public policies and agreements such as the free trade agreement between the two countries in force since 2005.","PeriodicalId":21210,"journal":{"name":"Revista de la Facultad de Ciencias Agrarias UNCuyo","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86611820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent decades, the continuous expansion of agriculture towards dry land zones has favored the migration and establishment of potential pests, such as arthropods, that may affect crops or be zoonotic agents. Based on the limited knowledge we have about the arthropod group present in the Limarí basin, our objective is to describe the taxonomic composition of the assemblage of economically important arthropods inhabiting this basin of the semiarid region of Chile. After reviewing historical data, specimen collections, and the specialized literature, a total of 414 arthropod species were recorded. Of the total number of species recorded, 92.5% were insects, the most diverse taxon, with 11 orders. Arachnids, in turn, were represented only by Acari with 31 species. The most widely represented orders of insects were Coleoptera, Hemiptera, and Lepidoptera. Within Coleoptera the most species-rich families were, in decreasing order of importance, Curculionidae, Coccinellidae, Cerambycidae, Scarabaeidae, Chrysomelidae (Bruchinae), Ptinidae, and Bostrichidae; within Hemiptera these were Aphididae, Diaspididae, Coccidae, Pseudococcidae, Pentatomidae and Rhopalidae; and within Lepidoptera they were Noctuidae and Tortricidae.

Thirty-six hybrids from crosses of 12 lines were evaluated at two sites in the Brazilian region known as Cerrado biome. The evaluated traits were: days to flowering, plant height, and grain yield.
