The study's objective was to evaluate a forest's environmental quality through orchid bees as bioindicators. In this investigation, collections were made at the undergrowth level by means of \"Bottle Traps\" and manual pools by zigzag method, in which entomological networks were used; the bees will be attracted by chemical attractants such as eucalyptus oil, the essence of eugenol and vanilla essence. We obtained a relatively high abundance with capture of 1024 individuals, and a richness of 38 species, the genus that dominated the study was the genus Euglossa with 89.5%, followed by the genus Eulaema with 9.6% and the genus Eufriesea with just 0.8 %, for the genus Exaerete that it is not possible to capture individuals, The completeness curve for the general sampling carried out allows us to observe representativeness of 99%. In conclusion, despite anthropic actions, the environmental quality in Cerro Llorón is quite stable because we found a very high abundance and species richness.","PeriodicalId":34452,"journal":{"name":"Manglar","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49066185","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}

A completely randomized design was used, with three chemical treatments (T1: Tifon 2.5% PS; T2: Chlorpyrifos S480; T3: Cyperklin 25) and a control. 160 larvae, Spodoptera frugiperda, in stage L3, were collected, and one larva was placed per maize plant. The evaluation was carried out every three days, from 28 days of sowing. The results indicated that the treatment threshold is 1.86%; 1.43%; 1.38% and 0.00% with T1, T2, T3 and control, respectively; T1 being the one with the highest tolerance to the presence of the pest.

Biological observations were performed in Alto de la Arena, corregimiento de Veladero, Tolé district, Chiriquí province, Panamá, where it was collected a total of 12 fruits of Spondias purpurea L., then carried to the laboratory and annotations on the biological cycle and behavioral data were performed daily. It was determined the biological cycle of Anastrepha obliqua (Macquart, 1835) has a duration of 30 to 32 days in the laboratory; the immature pupal stage presented the highest mortality, possibly due to the environmental conditions in the lab, which could be influencing in an early or late start of pupal stage.

Therefore, the trend of the Normalized Difference Vegetation Index (NDVI) in the Angostura Faical Regional Conservation Area was determined and the areas were quantified based on their trend over time. Geographic information systems, remote sensing and platforms such as Google Earth Engine made it possible to obtain data from Landsat 5-7-8 satellite images, and the R programming language was also used in the RStudio integrated development environment for statistical analysis with the Mann Kendall test which is qualitative in nature. It was found that in the time series the neutral trend predominates with a normal behavior in an area of 7,304,568 hectares, in a favorable case in the vegetation, 1,489,457 hectares were found with a positive trend and with a negative trend in the vegetation one surface of 0, 458 hectares located near the La Angostura creek where runoff is captured in rainy weather.

The objective of this research was to determine the cadaveric entomofauna and the ecological biodiversity associated with the remains of Sus scrofa domestica L. The work was carried out in the town of Chuyugual, La Libertad, a specimen of \"pig\" of 15 kg, was incinerated with diesel oil and protected with a metal cage. The insects were collected using conventional entomological techniques, species were determined with specialized taxonomic keys; for the determination of the ecological value of the cadaverous entomofauna and the most representative families were used the indices of Margalef, Simpson, Shanon and Pielou. The entomofauna found was distributed in 2 orders, 7 families, 12 species and 4 morphotypes. The 35% of relative abundance corresponds to the Calliphoridae family, 23% to the Sarcophagidae, 18% to the Staphilinidae and 6% to the Musidae, Fannidae, Dermestidae and Silphidae families. Biodiversity is high in dominance indices and the Pielou index; however, it is low in Shanon's specific wealth and equity indices. The Calliphoridae family has high diversity indexes; while the Sarcophagidae and Staphilinidae show moderate and low rates, respectively. It was concluded that the entomofauna found in the decomposition of Sus scrofa domestica belong to the order Diptera (Calliphoridae, Sarcophagidae, Muscidae and Fannidae) and Coleoptera (Staphilinidae, Silphidae and Dermestidae).","PeriodicalId":34452,"journal":{"name":"Manglar","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46512594","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}
