Revista Colombiana de Entomología <h2>Scope and editorial policy</h2> <p>The <em>Revista Colombiana de Entomología (RCdE) </em>is an electronic, international, open (Open Access) scientific journal with semi-annual continuous edition, co-edited between the Colombian Society of Entomology (SOCOLEN) and the University of Valle (Univalle), which publishes unpublished scientific papers in Spanish or English in the area of ​​entomology and related fields approved according to evaluation by external academic peers (double blind), in biodiversity, ecology, agriculture, human, veterinary and forensic medicine, physiology, systematics and taxonomy, biogeography and genetics. The journal publishes reviews of general entomological topics (commonly called "thematic reviews" and is expressly requested by the Editorial Committee), research papers, essays, scientific notes, book reviews and obituaries.</p> <p> </p> <p>RCdE is hosted on the website of the scientific journals of the Universidad del Valle (<a href=""></a>) and uses theplatform <em>Open Journal System</em> (OJS from PKP) in the editorial process (from submission to publication) and customer service to the reader. It charges authors per published page (with a differential rate for SOCOLEN members), publishes two annual volumes, with continuous edition, in the first semester (January-June) and second semester (July-December) of the year.</p> <p><span id="result_box" class="" lang="en"><span class=""> </span></span></p> Sociedad Colombiana de Entomología - SOCOLEN y Universidad del Valle - Univalle en-US Revista Colombiana de Entomología 0120-0488 <p>The copyright of the Revista Colombiana de Entomología belongs to the Sociedad Colombiana de Entomología.

This species can develop resistance to the insecticides used for its control. In the present study, abamectin selection pressure was performed for ten generations of P. xylostella, and the sublethal concentrations (CL20) and susceptible lines of the resistance were determined. Then, these concentrations were applied to third instar larvae. In two generations it was evaluated the effect on the percentage of pupae formed, pupal weight, adult emergence, and the development times of each phase from egg to adult.</p> <p>The resistance and application of sublethal concentrations have considerable costs in the biology and development of P. xylostella by increasing the percentage of pupation from one generation to another, and a greater weight of pupae and eggs per female/day. However, it presents a transgenerational effect by reducing oviposition in its generation; in terms of development time, it presented a harmful effect by prolonging it by more than seven days, which would generate a greater number of applications per cycle.</p> José Francisco Rodríguez-Rodríguez Ernesto Cerna-Chávez Yisa María Ochoa-Fuentes Jerónimo Landeros-Flores Luis Patricio Guevara-Acevedo Hugo Cesar Cisneros-López Copyright (c) 2021 José Francisco Rodríguez-Rodríguez, Ernesto Cerna-Chávez, Yisa María Ochoa-Fuentes, Jerónimo Landeros-Flores, Luis Patricio Guevara-Acevedo, Hugo Cesar Cisneros-López 2021-08-19 2021-08-19 47 2 10.25100/socolen.v47i2.10657 Report of Euseius consors (Acari: Phytoseiidae) on avocado trees of Michoacan, Mexico <p>To support the description of the diversity of Phytoseiidae mites and according to biological control, the mite Euseius consors is reported for Mexico. It was collected from avocado plants (Persea americana) in seven municipalities in the state of Michoacán, associated with Oligonychus persea (Acari: Tetranychidae), one of the most important pestmites in this crop. Hence, this scientific note is a contribution to the knowledge, the basis for the description of a potential biological control agent, and the ecosystem service that it can provide.</p> Mayra Ramos Lima José de Jesús Ayala-Ortega Ma Blanca Nieves Lara-Chávez Margarita Vargas-Sandoval Copyright (c) 2021 Mayra Ramos Lima, José de Jesús Ayala-Ortega, Ma Blanca Nieves Lara-Chávez, Margarita Vargas-Sandoval 2021-07-28 2021-07-28 47 2 e10243 e10243 10.25100/socolen.v47i2.10243 Revisión taxonómica de los géneros de escarabajos tigre neotropicales de la subtribu Odontocheilina (Coleoptera: Cicindelidae) Anderson Arenas James Montoya-Lerma Copyright (c) 2021 Anderson Arenas, James Montoya-Lerma 2021-09-02 2021-09-02 47 2 10.25100/socolen.v47i2.11574 Considerations on the status of the knowledge of coleopteran diversity (Arthropoda: Insecta) in Colombia <p>Coleoptera is one of the most diverse orders on the planet, and Colombia one of the most biodiverse countries. The combination of these two factors determines with no discussion a high concentration of species, with only partially known consequences in the country. In this work we describe the current state of knowledge about the diversity of coleopterans in Colombia, highlighting the role of entomological collections and the knowledge gaps to <br />tackle the national beetle fauna. This contribution is a starting point for coleopterologists of Colombia to begin working together towards a broader and less fragmented knowledge of the <br />natural history, systematics, ecology, and biogeography of the group.</p> Jennifer C.

We use FR to understand the coevolutionary relationships, and measured the biological response of the predators <em>Notonecta peruviana</em> and <em>Buenoa fasciata</em> in the control of fourth-stage larvae of <em>Aedes aegypti</em> (F<sub>1</sub>) at different densities (5, 10, 20, 35, 55 and 80 larvae / liter). Fasting predators (48 hours) were introduced to the test containers <br />(one individual per species) and the FR, the number of preys consumed (<em>Ne</em>), the attack coefficient (<em>a</em>) and handling time (Th). N. peruviana and <em>B. fasciata</em> developed a type II FR in the consumption of larvae of <em>Ae. aegypti</em> (<em>p</em> ≤ 0.01), and occupied close handling times (Th) (t = –1.93; df = 12; <em>p</em> = 0.078). <em>N. peruviana</em> preyed (Ne) twice as many larvae of <em>Ae. aegypti </em>(<em>p</em> ≤ 0.05) and showed a higher attack coefficient (<em>a</em>) in relation to <em>B. fasciata</em> (t = 14.92; <br />df = 12; p = 0.000). The predators <em>N. peruviana</em> and <em>B. fasciata</em> rapidly destabilized and consumed the preys. <em>N. peruviana</em> preyed twice as many larvae, attributable to the recent <br />predator-prey effect compared to the possible coevolutionary adjustment between <em>B. fasciata </em>and <em>Ae. aegypti</em>. It would be important to consider the predator species in the vector control <br />programs for aedine mosquitoes.</p> Yuri Olivier Ayala-Sulca Percy Colos-Galindo Edwin Portal-Quicaña Luis Ibarra-Juárez Reynán Cóndor-Alarcón Carlos Carrasco-Badajoz Rina Ramírez Copyright (c) 2021 Yuri Olivier Ayala-Sulca, Percy Colos-Galindo, Edwin Portal-Quicaña, Luis Ibarra-Juárez, Reynán Cóndor-Alarcón, Carlos Carrasco-Badajoz, Rina Ramírez 2021-07-22 2021-07-22 47 2 e10535 e10535 10.25100/socolen.v47i2.10535
