This study aimed to assess the influence of different temperatures on the development of</span><em><span style="font-weight: 400;"> A. basistriata</span></em><span style="font-weight: 400;"> and determine its thermal requirements. The insect was fed with larvae of </span><em><span style="font-weight: 400;">Tenebrio molitor</span></em><span style="font-weight: 400;"> (Coleoptera: Tenebrionidae) and maintained at 18, 22, 25, and 28 ± 1 °C, 70 ± 10 % relative humidity, and 14-hour photoperiod. There were significant differences in the development time of stages and instars of </span><em><span style="font-weight: 400;">A. basistriata </span></em><span style="font-weight: 400;">as a function of temperature. Threshold temperatures for egg, larva, pupa, and preimaginal development were 10.68, 11.32, 12.67, and 11.73 °C, respectively. The thermal constants were 82.41, 264.83, 84.57, and 664.89 degree-days, respectively. The highest number of </span><em><span style="font-weight: 400;">A. basistriata</span></em><span style="font-weight: 400;"> individuals reached the adult stage in the shortest time of development at 28 °C, where 70 % of survival was recorded. This finding suggests that 28 °C is the most favorable temperature for rearing this carabid species under laboratory conditions.</span></p> 2024-06-21T00:00:00-05:00 Copyright (c) 2024 Maria José Araújo Wanderley, Francisco Jorge Cividanes, Nivânia Pereira da Costa-Menezes, Sidnéia Terezinha Soares de Matos, Rener Luciano de Souza Ferraz https://revistacolombianaentomologia.univalle.edu.co/index.php/SOCOLEN/article/view/12725 Occurrence of Ancistrosoma klugii Curtis (Coleoptera: Scarabaeidae: Melolonthinae), and its importance as a possible phytosanitary risk in Peru 2024-03-12T17:09:00-05:00 Agustina Valverde-Rodríguez avalverde@unheval.edu.pe Efraín David Esteban Nolberto nolberto.david@unh.edu.pe David Ruiz-Vilchez david.ruiz@unh.edu.pe Dalila Illatopa Espinoza dillatopa@unheval.edu.pe <p><span style="font-weight: 400;">The objective of the present study is to report the feeding and copulation habits and provide a diagnosis of the adult stage of </span><em><span style="font-weight: 400;">Ancistrosoma klugii</span></em><span style="font-weight: 400;"> and its importance as a possible phytosanitary risk based on specimens collected in the department of Huánuco, Peru, where the insect is a polyphagous pest at certain times of the year.

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.

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.

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> 2024-06-04T00:00:00-05:00 Copyright (c) 2024 Erik Daniel Narvaez-Vidal, Diana Marcela Urcuqui, Anderson Arenas, Inge Armbrecht https://revistacolombianaentomologia.univalle.edu.co/index.php/SOCOLEN/article/view/13135 First record of Caliothrips phaseoli (Hood, 1912) (Thysanoptera: Thripidae) on Arachis spp. (Fabaceae) in Brazil 2024-04-28T23:06:30-05:00 Rodrigo Souza Santos rodrigo.s.santos@embrapa.br Élison Fabrício Bezerra Lima elisonfabricio@hotmail.com <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.
