Platycyamus regnellii trees fertilized with dehydrated sewage sludge presented significantly more leavesper branch, branches per tree, and a higher percentage of ground cover compared to unfertilized trees. Phenacoccus sp. (Pseudococcidae) was the most abundant phytophagous insect associated with P. regnellii trees. Fertilization did not affect the abundance, diversity, and species richness of Hemiptera phytophagous on P. regnellii trees. However, fertilizedtrees presented higher abundance and species richness of trophobiont-tending ants compared to unfertilized trees, with Camponotus sp. being the most abundant regardless of the treatment. Fertilized P. regnellii trees also presented higher species richness of natural enemies compared to unfertilized ones, with Aranae and Dolichopodidae being the most abundant. We concluded that fertilization with dehydrated sewage sludge improved P. regnellii trees leafmass and ground cover and increased the diversity of trophobiont-tending ants and natural enemies. To our knowledge, this is the first study on the arthropods community associated withthis tree species.

This work presents the results of analyzing the data from an experiment carried out at the Research Station of Cenipalma located in the municipality of Barrancabermeja (Colombia). The experiment was established to evaluate, at the field level, the entomopathogenic fungus Purpureocillium lilacinum as a strategy to control the population of the lace bug, Leptopharsa gibbicarina. The experiment was carried out in two plots, in one of them, the control of L. gibbicarina with P. lilacinum was implemented as suggested by the Entomology research program of Cenipalma and, in the other plot there was no control strategy. The data were analyzed by using GLM and two different density functions (Poisson and the negative binomial). Results showed statistically significant differences between the treatments. The estimator of the maximum likelihood associated with the P. lilacinum treatment indicated that the application of the entomopathogenic fungus reduced the populations of L. gibbicarina with a rate of incidence of 0.28 times more than the control.","PeriodicalId":54476,"journal":{"name":"Revista Colombiana de Entomologia","volume":"1 1","pages":"2-5"},"PeriodicalIF":0.4,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80776710","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}
