Hass https://revistacolombianaentomologia.univalle.edu.co/index.php/SOCOLEN/article/view/12785 <p><span style="font-weight: 400;">Determining the spatial distribution of populations of </span><em><span style="font-weight: 400;">Heilipus lauri</span></em><span style="font-weight: 400;"> and </span><em><span style="font-weight: 400;">Stenoma catenifer</span></em><span style="font-weight: 400;">, insects of economic and quarantine importance in avocado, is a useful information for designing and implementing integrated pest management plans. Aggregate spatial distribution is considered one of the most common patterns in nature, however, it has not been documented for these insect pest species. We propose through spatial statistical methods the analysis of data from periodic monitoring where the number of fruits with damage (FWD) caused by the two insect pests was recorded. The study was conducted between 2019-2020 in four commercial orchards of avocado cv. Hass in the department of Cauca, Colombia. A sampling design was established based on the recognition of damage on previously geopositioned trees. The spatial distribution was determined through Taylorʼs power law and Ripleyʼs K function. Taylorʼs aggregation coefficient (b) was 1.47 and 1.22 for </span><em><span style="font-weight: 400;">H. lauri</span></em><span style="font-weight: 400;"> and </span><em><span style="font-weight: 400;">S. catenifer</span></em><span style="font-weight: 400;">, respectively, indicating aggregation. Ripley's K function identified aggregation points of FWD in a radius range of 3-35 meters, with the aggregation sites being consistent across the two productive cycles. The damage was mapped indicating aggregation sites that will allow the implementation of management strategies for quarantine importance insect pests of avocado in specific sites of the crop, showing the precise location of the greatest concentration of damage and populations of </span><em><span style="font-weight: 400;">H. lauri</span></em><span style="font-weight: 400;"> and </span><em><span style="font-weight: 400;">S. catenifer.</span></em></p> Juan Camilo Zapata Calero, Arturo Carabali Muñoz, David Arango Londoño Copyright (c) 2025 Juan Camilo Zapata Calero, Arturo Carabali Muñoz, David Arango Londoño https://creativecommons.org/licenses/by-nc-sa/4.0 https://revistacolombianaentomologia.univalle.edu.co/index.php/SOCOLEN/article/view/12785 Mon, 16 Jun 2025 00:00:00 -0500 Molecular Characterization of a Native Nematode, Pristionchus pacificus (Nematoda Class: Rhabditida: Diplogastridae) From Avocado Soils in Mexico https://revistacolombianaentomologia.univalle.edu.co/index.php/SOCOLEN/article/view/13819 <p><span style="font-weight: 400;">Avocado </span><em><span style="font-weight: 400;">Persea americana</span></em><span style="font-weight: 400;"> Mill., is a crop of great economic importance in Mexico and it is affected by pests that cause significant damage. Traditionally, pest control in avocado crops has been based on the use of organosynthetic pesticides; however, their excessive and indiscriminate use has negative effects on the environment, health, and quality of the fruit. In the search for more sustainable alternatives for the control of agricultural pests, the use of entomopathogenic nematodes (EPNs) as biological control agents is one of the most promising options. To explore possible EPNs associated with avocado crops, soil samples were collected from six avocado orchards in the municipality of Atapan, Michoacán, Mexico, and possible entomopathogenic agents were isolated using the bait insect technique with </span><em><span style="font-weight: 400;">Galleria mellonella</span></em><span style="font-weight: 400;"> larvae. The molecular characterization through partial sequencing of the SSU (Small Subunit) and ITS (Internal Transcribed Spacer) regions of strain ANP003 confirmed that one of the isolates corresponds to the species </span><em><span style="font-weight: 400;">Pristionchus pacificus</span></em><span style="font-weight: 400;">, this represents the first report in Mexico of a nematode associated with avocado crop. The genetic distance analysis of SSU-18S allowed us to know the close relationship of this isolate with the entomopathogenic nematode </span><em><span style="font-weight: 400;">Pristionchus entomophilus</span></em><span style="font-weight: 400;">.</span></p> Luis Enrique Flores-Pantoja, Ma.

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.

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 &gt; 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> Carmen Sinti-Hesse, Carlos Tong-Rios, Miguel Angel Farfán-García, Fabiola Díaz-Soria, José Espinoza, Karine Zevallos Copyright (c) 2025 Carmen Sinti-Hesse, Carlos Tong-Rios, Miguel Angel Farfán-García, Fabiola Díaz-Soria, José Espinoza, Karine Zevallos https://creativecommons.org/licenses/by-nc-sa/4.0 https://revistacolombianaentomologia.univalle.edu.co/index.php/SOCOLEN/article/view/12651 Wed, 19 Mar 2025 00:00:00 -0500 In Memoriam AMADOR VILLACORTA MOSQUEIRA (1935-2014) https://revistacolombianaentomologia.univalle.edu.co/index.php/SOCOLEN/article/view/14683 Juan F.
