Mexico has become one of the main producers of this crop worldwide, but few studies have focused on the diversity of species present in blueberries in Mexico. Thus, the objective of this research was to report the diversity and abundance of mites associated with </span><em><span style="font-weight: 400;">V. corymbosum</span></em><span style="font-weight: 400;"> cultivation in Michoacán (Mexico). Plant material was collected in 42 orchards of 18 municipalities of Michoacán. Samples were placed in plastic bags and stored under refrigeration at 4 °C. Mites were processed for mounting in semi-permanent preparations with Hoyer's solution and identified using taxonomic keys. A total of 17 species of mite belonging to 12 genera, five families and three orders were collected. The families with the greatest abundance were Tetranychidae and Tenuipalpidae. Whereas Phytoseiidae was the most diverse with 11 species. The municipality of Peribán and the Biloxi variety were those that presented the greatest diversity and abundance. Of the identified species </span><em><span style="font-weight: 400;">Oligonychus ilicis</span></em><span style="font-weight: 400;">, </span><em><span style="font-weight: 400;">Neoseiulus rufus</span></em><span style="font-weight: 400;">, </span><em><span style="font-weight: 400;">Typhlodromips jimenezi</span></em><span style="font-weight: 400;"> and </span><em><span style="font-weight: 400;">Metaseiulus bidentatus</span></em><span style="font-weight: 400;"> are new records for Mexico. The phytophagous species </span><em><span style="font-weight: 400;">O. ilicis</span></em><span style="font-weight: 400;"> and </span><em><span style="font-weight: 400;">Brevipalpus yothersi</span></em><span style="font-weight: 400;"> must be further studied since they can become important pests for the crop. This research will be a starting point for further study of mites in blueberries in Mexico.</span></h2>2025-01-27T00:00:00-05:00Copyright (c) 2025 José De Jesús Ayala-Ortega, Edith Guadalupe Estrada Venegas, Armando Equihua-Martínez, Héctor González-Hernández, Héctor González-Hernández, Margarita Vargas-Sandovalhttps://revistacolombianaentomologia.univalle.edu.co/index.php/SOCOLEN/article/view/12651Effect of six diets during the larval and adult period of Aedes aegypti (Diptera: Culicidae) under laboratory conditions2025-03-19T09:40:41-05:00Carmen Sinti-Hessecarsinhes@gmail.comCarlos Tong-Riosctong32@gmail.comMiguel Angel Farfán-Garcíamfgarcia442@gmail.comFabiola Díaz-Soriafabiodiaz@hotmail.comJosé Espinozajespinozas@uni.edu.peKarine Zevalloskarine.zevallos@unapiquitos.edu.pe<p><span style="font-weight: 400;">Rearing the laboratory vector </span><em><span style="font-weight: 400;">Aedes aegypti</span></em><span style="font-weight: 400;"> (Diptera: Culicidae), a disease vector, necessitated diets nutritionally rich in protein and carbohydrates, yet low in fat. The objective of this study was to evaluate and compare the effects of various diets on larval and adult stages, with a specific focus on wing size. Six diets were compared: CIETROP-CC concentrate, fish-based diets (Nutrafin-NF and Aqua One-AO), carnivore-based diets (Ricocan-RC and Supercat-SC), and brewer's yeast (LV). The development of larval stages was assessed using Kaplan-Meier survival analysis, while wing length was compared using Mood's median test. The developmental duration from larva to adult was consistent across all six diets, averaging 13 days. Larvae fed LV exhibited a lower survival rate (88 %) compared to the other diets (99%). Female wing size ranged from 2.81 to 2.93 mm, with a mean of 2.88 mm and a standard deviation of 0.12, while male wing size ranged from 2.18 to 2.28 mm, with a mean of 2.23 mm and a standard deviation of 0.17. All diets supported satisfactory larval development, with no significant differences observed in larval survival or developmental duration (P > 0.05). Notably, the CIETROP-CC and commercial diets yielded similar results. These findings indicate that the laboratory-prepared diet exhibited comparable performance to the other five diets in terms of survival and developmental rates. Further analysis will enable the determination of its specific nutritional composition. The results underscore the efficacy of commercial diets in supporting larval.</span></p>2025-03-19T00:00:00-05:00Copyright (c) 2025 Carmen Sinti-Hesse, Carlos Tong-Rios, Miguel Angel Farfán-García, Fabiola Díaz-Soria, José Espinoza, Karine Zevalloshttps://revistacolombianaentomologia.univalle.edu.co/index.php/SOCOLEN/article/view/13038Evaluación de la patogenicidad de Metarhizium robertsii y Beauveria bassiana contra Chloridea virescens (Lepidoptera: Noctuidae)2025-04-04T14:01:55-05:00Cipriano García Gutiérrezcgarciag@ipn.mxLucía Araceli Manzanarez-Jiménezingenieria_kaizen@hotmail.comNinfa M, Rosas-Garcíanrosas@ipn.mxAntonio Luna González aluna@ipn.mx<p><span style="font-weight: 400;"> In Mexico, </span><em><span style="font-weight: 400;">Chloridea virescens</span></em><span style="font-weight: 400;"> is a pest of chickpea, tomato and other vegetables causing significant economic losses. To control this pest, three different strains (M1, M2 and M3) of </span><em><span style="font-weight: 400;">Metarhizium robertsii</span></em><span style="font-weight: 400;"> (Previously </span><em><span style="font-weight: 400;">Metarhizium anisopliae</span></em><span style="font-weight: 400;">) and three strains of </span><em><span style="font-weight: 400;">Beauveria bassiana</span></em><span style="font-weight: 400;"> (B1, B3 and B9) were evaluated under laboratory conditions, based on radial growth parameters, and conidia production and germination. The pathogenicity of the best strains was assessed at concentration of 1×10</span><span style="font-weight: 400;">8</span><span style="font-weight: 400;"> conidia/mL, against second and third instar larvae of </span><em><span style="font-weight: 400;">C. virescens</span></em><span style="font-weight: 400;">, at 28 ± 1 °C, 70 ± 5 % of relative humidity and a photoperiod of 12 hours light. The six strains caused larvae mortality of </span><em><span style="font-weight: 400;">C. virescens</span></em><span style="font-weight: 400;">, ranging from 57 % to 97 %, with statistically significant differences compared with the control (</span><em><span style="font-weight: 400;">P</span></em><span style="font-weight: 400;"> < 0.02). The M1 strain of </span><em><span style="font-weight: 400;">M. robertsii</span></em><span style="font-weight: 400;"> exhibited the highest radial growth of 4.79 ± 0.02 cm, a growth rate of 3.33 mm/day, and a production of 6×10</span><span style="font-weight: 400;">9</span><span style="font-weight: 400;"> conidia/mL at 14 days, with 96 % of germination at 24 hours. In terms of pathogenicity M1 caused 97 % of total larvae mortality at 7 days with TL</span><span style="font-weight: 400;">50</span><span style="font-weight: 400;"> of 4 days. The M2 and M3 strains caused mortality of 83 % and 77 % with a TL</span><span style="font-weight: 400;">50 </span><span style="font-weight: 400;">of 4 days. Strains B1, B3 and B9 have mortalities of 63 %, 57 % and 70 % with a TL</span><span style="font-weight: 400;">50</span><span style="font-weight: 400;"> of 4,3 days. (M1) </span><em><span style="font-weight: 400;">M. robertsii</span></em><span style="font-weight: 400;"> had the best performance across all evaluated parameters, and it is therefore recommended for field testing to control of </span><em><span style="font-weight: 400;">C. virescens</span></em><span style="font-weight: 400;">.</span></p>2025-04-04T00:00:00-05:00Copyright (c) 2025 Cipriano García Gutiérrez, Lucía Araceli Manzanarez-Jiménez, Ninfa M, Rosas-García, Antonio Luna González https://revistacolombianaentomologia.univalle.edu.co/index.php/SOCOLEN/article/view/14683In Memoriam AMADOR VILLACORTA MOSQUEIRA (1935-2014)2025-01-10T17:34:00-05:00Juan F.
