The habits of the insect were monitored through observations of the populations in the field. Groups of </span><em><span style="font-weight: 400;">A. klugii</span></em><span style="font-weight: 400;"> were observed made up of 6 to 8 individuals close to each other, found in the floral parts, foliage and branches of citrus trees, avocado trees, mangoes, grapevines and alfalfa fields, feeding and copulating simultaneously, especially in the morning hours, from 8:00 am to 10:00 am. In alfalfa crops, up to an average of 42 adult individuals per square meter could be counted. Differences were found in the size of male and female individuals with 27.2 mm in length and 24.4 mm, respectively, as well as differences in the abdominal sternites with a modification in a reduction of the sternites to a spine and a heavily sclerotized stooped aedeagus in the male; and the female with an abdomen without the spine, with the anterior margin of the pygidium sinuous.</span></p> Agustina Valverde-Rodríguez Efraín David Esteban Nolberto David Ruiz-Vilchez Dalila Illatopa Espinoza Copyright (c) 2024 Agustina Valverde-Rodríguez, Efraín David Esteban Nolberto, David Ruiz-Vilchez , Dalila Illatopa Espinoza 2024-03-12 2024-03-12 50 1 10.25100/socolen.v50i1.12725 Strategus aloeus (Coleoptera: Scarabaeidae) damage in two agave species and its management based on entomopathogenic fungi in oil suspensions <p><span style="font-weight: 400;">Due to its agroecological characteristics, more than 24 species of agave have been developed and cultivated in the state of Oaxaca, Mexico, which have been fully exploited for the production of mezcal, an activity of economic importance. This crop is affected by the incidence of </span><em><span style="font-weight: 400;">Strategus aloeus</span></em><span style="font-weight: 400;"> (Coleoptera: Scarabaeidae), an insect that causes damage and losses of economic importance to agave plants less than 3 years of age, for its control systemic insecticides are used; however, due to the habits of the insect, biological control is an alternative for its management. In this study, losses and damage caused by adults of </span><em><span style="font-weight: 400;">S. aloeus</span></em><span style="font-weight: 400;"> on </span><em><span style="font-weight: 400;">Agave potatorum</span></em><span style="font-weight: 400;"> Zucc. and </span><em><span style="font-weight: 400;">A. angustifolia</span></em><span style="font-weight: 400;"> Haw. were determined from field observations. In the laboratory, two entomopathogenic fungi, </span><em><span style="font-weight: 400;">Beauveria bassiana</span></em><span style="font-weight: 400;"> and </span><em><span style="font-weight: 400;">Metarhizium robertsii</span></em><span style="font-weight: 400;"> (formerly known as </span><em><span style="font-weight: 400;">M. anisopliae</span></em><span style="font-weight: 400;">), were evaluated at a concentration of 1X107 conidia/insect in vegetable oil emulsions (</span><em><span style="font-weight: 400;">Persea americana</span></em><span style="font-weight: 400;">, </span><em><span style="font-weight: 400;">Ricinus communis,</span></em><span style="font-weight: 400;"> and </span><em><span style="font-weight: 400;">Prunus dulcis</span></em><span style="font-weight: 400;">) at two concentrations of 20 % and 40 %. The damage found for </span><em><span style="font-weight: 400;">A. potatorum</span></em><span style="font-weight: 400;"> with a sample size of 85 plants evaluated was 79.90 %. For </span><em><span style="font-weight: 400;">A. angustifolia</span></em><span style="font-weight: 400;">, with the same number of plants, 65.86 % damage was found. The losses found in 85 plants of </span><em><span style="font-weight: 400;">A. angustifolia</span></em><span style="font-weight: 400;"> with damage grades 4 and 5 were 1 794.9 and 2 227.5 g/plant and for </span><em><span style="font-weight: 400;">A. potatorum</span></em><span style="font-weight: 400;"> with damage grades 4 and 5 were 1 631.9 and 2 119.7 g/plant.

Currently, the citrus leprosis disease is associated with several viruses of the genera </span><em><span style="font-weight: 400;">Cilevirus</span></em><span style="font-weight: 400;"> and </span><em><span style="font-weight: 400;">Dichoravirus</span></em><span style="font-weight: 400;">. In Colombia, symptoms of citrus leprosis have been related to citrus leprosis virus C (CiLV-C - </span><em><span style="font-weight: 400;">Cilevirus leprosis</span></em><span style="font-weight: 400;">) and citrus leprosis virus C2 (CiLV-C2 - </span><em><span style="font-weight: 400;">Cilevirus colombiaense</span></em><span style="font-weight: 400;">). To detect leprosis-associated viruses in plants of the family Orchidaceae and identify the possible associated vectors, inspections and samplings were carried out on garden plants and orchid crops, and molecular detection of viruses and the taxonomic identification of mites were accomplished. As a result, </span><em><span style="font-weight: 400;">Brevipalpus californicus s. l.</span></em><span style="font-weight: 400;">, </span><em><span style="font-weight: 400;">B. phoenicis</span></em> <em><span style="font-weight: 400;">s.s.</span></em><span style="font-weight: 400;">, and </span><em><span style="font-weight: 400;">B. essigi </span></em><span style="font-weight: 400;">(Prostigmata: Tenuipalpidae) are recorded for the first time on orchid plants from Colombia. A taxonomic key is provided to identify mites of the family Tenuipalpidae on orchids worldwide. The implications of these mites for the phytosanitary protection in citrus crops of Colombia are discussed.</span></p> José Mauricio Montes-Rodríguez Janeth Alexandra Sierra Monroy Guillermo Adolfo León Martínez Aline Daniele Tassi Copyright (c) 2024 José Mauricio Montes-Rodríguez, Janeth Alexandra Sierra Monroy, Guillermo Adolfo León Martínez, Aline Daniele Tassi 2024-05-17 2024-05-17 50 1 10.25100/socolen.v50i1.12895 Climate and its relationship with the population dynamics and dispersion of the coffee berry borer Hypothenemus hampei in an altitudinal gradient in the Risaralda River basin, Caldas, Colombia <p><span style="font-weight: 400;">The population dynamics of the Coffee Berry Borer (CBB),</span><em><span style="font-weight: 400;"> Hypothenemus hampei</span></em><span style="font-weight: 400;"> was studied under different climatic and altitudinal conditions, in five </span><em><span style="font-weight: 400;">Coffea arabica</span></em><span style="font-weight: 400;"> plots, with a density of 5,000 trees in an altitudinal gradient, where meteorological stations were installed. In each plot, 30 trees were randomly selected, and the levels of infestation, dispersion and population density were evaluated every month for 3 years. The results showed an increase of 23.9 %, 20.2 % and 5.9 % of CBB infestation at 1,132 m during an El Niño, Neutral and La Niña period respectively, in contrast to 5.3 %, 2.1 % and 2.5 % infestation at 1,822 m. The average number of CBB individuals per tree during an El Niño period was 1,850, compared to 1,376 and 629 individuals during a Neutral and La Niña period. The temperature showed an increase of 2,5°C above the historical average due to the effects of the El Niño phenomenon. CBB dispersal showed a positive and negative exponential relationship with temperature and altitude, with a cumulative total of 2´815,332 individuals caught in traps during the El Niño period, compared to 1´650,897 and 173,814 in a Neutral and La Niña period, respectively. There was a natural epizootic of the </span><em><span style="font-weight: 400;">Beauveria bassiana</span></em><span style="font-weight: 400;"> fungus that caused mortalities between 85 % and 95 % in the CBB populations. Altitudinal transects in the same hydrographic basin serve to understand the interactions between pests, the climate, and their natural enemies, which allow generating early warnings to develop control strategies.</span></p> Luis Miguel Constantino Chuaire Andrés Javier Peña Quiñones Carolina Ramírez Carabalí Luis Carlos Imbachi Quinchua Pablo Benavides Machado Copyright (c) 2024 Luis Miguel Constantino, Andrés Javier Peña Quiñones, Carolina Ramírez Carabalí, Luis Carlos Imbachi Quinchua, Pablo Benavides Machado 2024-06-11 2024-06-11 50 1 10.25100/socolen.v50i1.12946 The Development and survival of Triatoma barberi and Triatoma longipennis (Hemiptera: Reduviidae) is affected by Trypanosoma cruzi colonization <p><span style="font-weight: 400;">Triatomines are insect vectors of the flagellate protozoan </span><em><span style="font-weight: 400;">Trypanosoma cruzi</span></em><span style="font-weight: 400;">, the causative agent of Chagas disease. This occurs when the triatomine defecates on the skin of the vertebrate host when it bites its host for feeding. This lesion causes the penetration of </span><em><span style="font-weight: 400;">T. cruzi</span></em><span style="font-weight: 400;">, whose infective phase is the tripomastigote, and the non-infective replicative phase epimastigote. Although the effects of </span><em><span style="font-weight: 400;">T. cruzi</span></em><span style="font-weight: 400;"> on the development and survival of different species of triatomine bugs are known, it has not been fully described how the parasite affects many of the species that inhabit Mexico. Therefore, the present study aimed to investigate the effect of the presence of </span><em><span style="font-weight: 400;">T. cruzi</span></em><span style="font-weight: 400;"> on triatomine development and survival. For this, five triatomines of each instar of each species, </span><em><span style="font-weight: 400;">Triatoma barberi</span></em><span style="font-weight: 400;"> and </span><em><span style="font-weight: 400;">Triatoma</span></em> <em><span style="font-weight: 400;">longipennis</span></em><span style="font-weight: 400;">, were inoculated, from their second instar to their adult stage, female or male. Each triatomine was infected with 3-5 x10</span><span style="font-weight: 400;">5</span><span style="font-weight: 400;"> parasites and they were incubated for 100 days and the kinetic of parasites in the feces and </span><em><span style="font-weight: 400;">T. cruzi</span></em><span style="font-weight: 400;"> phases were recorded. The results showed that </span><em><span style="font-weight: 400;">T. barberi</span></em><span style="font-weight: 400;"> and </span><em><span style="font-weight: 400;">T. longipennis</span></em><span style="font-weight: 400;"> development was affected in all stages because of </span><em><span style="font-weight: 400;">T. cruzi</span></em><span style="font-weight: 400;"> infection. It was greater for </span><em><span style="font-weight: 400;">T. longipennis</span></em><span style="font-weight: 400;">, both in its mortality, as well as time to molt in each phase.</span></p> Marco Antonio Becerril-Flores Ana Karen Benítez-Hernández Antonio Santos-Castañeda María del Rosario Tovar-Tomás Eva María Molina-Trinidad Copyright (c) 2024 Marco Antonio Becerril-Flores, Ana Karen Benítez-Hernández, Antonio Santos-Castañeda, María del Rosario Tovar-Tomás, Eva María Molina-Trinidad 2024-03-13 2024-03-13 50 1 10.25100/socolen.v50i1.12874 Diversity trends of ants and carabids in four altitudes at the Farallones Natural Park, Colombia <p><span style="font-weight: 400;">The different environmental conditions throughout the habitats at different altitudes of the tropical Andes allow the settlement and stratification of a great diversity of flora and fauna, including insects. In order to evaluate the change in the diversity of ants and carabid beetles as a function of an altitudinal gradient in the National Natural Park Farallones de Cali (Colombian southwest), the ant and carabid fauna were analyzed in a sub-Andean Forest (1600 m a.s.l.), an Andean Forest (2400 m a.s.l.), a high Andean Forest (3200 m a.s.l.) and a paramo ecosystem (3800 m a.s.l.). In each altitude, the specimens were collected with pitfall traps, manually, foliage agitation, leaf litter sifting with mini-Winkler bags extraction, and light traps in a standardized way was carried out during a single expedition of five days at each locality. Diversity was evaluated through accumulation curves and diversity indices with the Hill series and its comparison between locations was made through additive partitioning and NMDS. The results support a decrease in ant diversity with increasing altitude, and an accumulation of carabid diversity at intermediate altitudes of the gradient. The diversity of both groups is consistent with Rapoport's altitudinal rule. Each altitude presented a unique species composition, except for carabids found at the high Andean and sub-Andean forests. This study contributes to the knowledge of the diversity of insects in forests, moorland (paramos) and sub-moorlands of the PNN Farallones de Cali, which until now, was almost unknown and will also serve as a basis for future studies.</span></p> Erik Daniel Narvaez-Vidal Diana Marcela Urcuqui Anderson Arenas Inge Armbrecht Copyright (c) 2024 Erik Daniel Narvaez-Vidal, Diana Marcela Urcuqui, Anderson Arenas, Inge Armbrecht 2024-06-04 2024-06-04 50 1 10.25100/socolen.v50i1.13057 First record of Caliothrips phaseoli (Hood, 1912) (Thysanoptera: Thripidae) on Arachis spp. (Fabaceae) in Brazil <p><span style="font-weight: 400;">The objective of this work was to </span><span style="font-weight: 400;">establish</span><span style="font-weight: 400;"> the first record of </span><em><span style="font-weight: 400;">Caliothrips phaseoli</span></em><span style="font-weight: 400;"> (Hood, 1912) (Thysanoptera: Thripidae); in forage peanut accessions in the state of Acre, Brazil.
