These insects’ communities tend to exhibit temporal variations in the distribution and abundance of their species, and during outbreak years cause important economic loss in both implanted pastures and crops. In the study area, Laprida county, as well as in other areas of Buenos Aires province, this pest problem has been recognized since last century. The aim of this study was to analyze the pest management of grasshoppers made by farmers and related institutions in Laprida using both qualitative (interviews and documentary observation) and quantitative methods (surveys). About 80% of surveyed farmers considered that grasshoppers are the main pest in the region, and 60% of them apply chemical insecticides against this pest, mainly on crops. Besides, only 12.8% of surveyed farmers are aware of nonchemical alternatives for pest control, such us biological control and natural enemies. Most of the interviewed farmers acknowledged the importance of preventive management through systematic grasshopper monitoring and spot treatments in risky areas. Additionally, farmers showed interest in the implementation of more environmentally-safer strategies such as biological control.","PeriodicalId":54250,"journal":{"name":"Revista De La Sociedad Entomologica Argentina","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46207958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-six locations were surveyed to accomplish the first specific exploration on the diversity of Miltogramminae in southern Andean areas of South America. We evaluated changes in abundance, richness and composition among habitat types to establish the effect of anthropization on the Miltogramminae community. Habitat types were considered as human modified (trails and roads, parks and meadows) and natural sites (watercourses and lake beaches, sandy and shrubby areas), distributed in two ecoregions (Valdivian forest and Patagonian steppe). We found differences in the capture rate and composition of Miltogramminae among habitat types. The species Opsidia intonsa Aldrich was highly dominant in samples, with higher proportional abundance in human modified habitats. Richness of Miltogramminae was higher in natural sites. Comparisons between the ecoregions surveyed indicated the genus Opsidia Coquillett did not show differences in abundance between ecoregions, whereas Senotainia Macquart was more abundant in the Patagonian steppe. The results provide evidence on the significant effects of human influence on landscapes in kleptoparasitic fly diversity. Slight modifications of natural areas (as proliferation of trails or isolated houses) should be addressed to evaluate the conservation of kleptoparasitic Diptera.","PeriodicalId":54250,"journal":{"name":"Revista De La Sociedad Entomologica Argentina","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46716724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Honeybees are used to transfer pollen between male and female kiwifruit (Actinidia deliciosa Liang & Ferguson) plants, increasing fruit quality and crop yield. Our main goal was to determine the effect of stimulating Apis mellifera L. colonies with standard food supplies on the collection of kiwifruit pollen. However, honey bees can also forage other flowering species in the crop site's surrounding areas. We selected kiwifruit as a model to analyze the effects of food supply on pollen collection of the target crop. The following experimental treatments (n = 5 hives each were conducted in a kiwifruit orchard in Mar del Plata, Argentina: Group J/A: supplied with sugar syrup (2:1 + liquid protein supplements (“Apipromotor ®”; Group J/P: supplied with sugar syrup (2:1 + solid protein supplements (“patty”; Group J: supplied with sugar syrup (2:1; Group C: control, not supplied.
