... From ten years to date in Durango, Mexico, studies have been carried out that have made it possible to know the taxonomic diversity of parasitoids of FAW of the families: Ichneumonidae (Pristomerus spinator Fabricius, Campoletis sonorensis Cameron) [25], Encyrtidae (Euplectrus plathypenae Howard), Tachinidae (Lespesia aletiae Riley, L. archippivora Riley, Winthemia deilephilae Osten Sacken, y Archytas marmoratus Townsend) [26], Trichogrammatidae (Trichogramma pretiosum Riley y Trichogramma exiguum Pinto y Platner) and Scelionidae (Telenomus remus Nixon) [27], and of the family Braconidae subfamily Homolobinae (Homolobus truncator Say) [28], from this same family Ch. insularis, Ch. sonorensis, Microchelonus cautus [29], M. laphygmae y M. arizonensis [30] the genetic part has also been studied [31,32]. ...
The fall armyworm Spodoptera frugiperda Smith (Lepidoptera: Noctuidae) is the main pest that attacks maize crops in Durango, Mexico. For its biological control, it is desired to use the parasitoids of the Braconidae family; however, its identification is quite complex due to the lack of taxonomic keys that describe the complete morphological characters or are well-defined. It is necessary to study their genetic characters to estimate the variation within populations and species. For this, DNA extraction and amplification by PCR were carried out, as well as the sequencing of a fragment of subunit I of the cytochrome c oxidase (COI) gene. In Chelonus sp., morphological variability was observed between Ch. insularis and Ch. sonorensis, their genetic distances were conspecific, indicating that they probably belong to the same lineage. In Meteorus, taxonomically two species were found that had not been reported for Durango: M. laphygmae and M. arizonensis; however, the genetic distance between these and the species reported in the Genbank® could indicate that it is a single species. These results showed the high morphological and genetic variability in these braconids, probably due to evolutionary and climatic changes.
... Biological control provided by the natural enemies of D. arcanella presented a strong positive correlation with the population of the pest insect and a negative correlation with the temperature; this agrees with studies that report that these biological control agents respond quickly to changes in the population dynamics of their host and to climatic variations [30,33]. Additionally, parasitoid insects from the Braconidae, Chalcididae, and Ichneumonidae families have been reported as important biological controllers not only in the Depressariidae family but also in other Lepidoptera [22,[34][35][36][37][38]. ...
Colombia currently has 595,722 oil palm-cultivated hectares, but production is declining due to phytophagous insects feeding mainly on the leaves; one of them, Durrantia arcanella, is a recurring pest in the northern palm zone of Colombia, for which we do not have all the essential information. Therefore, it was proposed to determine its biology, foliar consumption rate, population fluctuation, and relationship with climatic variables and to identify its main natural enemies in the department of Cesar. The life cycle under laboratory conditions, including adult longevity, was 48.0 ± 10.1 days, the egg stage lasted 8.0 ± 0.7 days, the larva stage lasted 24.2 ± 6.2 days, the pre-pupa stage lasted 1.5 ± 0.5 days, the pupa stage lasted 7.1 ± 0.9 and the adult had a longevity of 7.2 ± 2.0 days. At the end of the larval period, it was determined that they individually consumed 8.2 ± 5.3 cm2 of leaflets. Correlation was found between D. arcanella population dynamics and climatic factors such as temperature and relative humidity, likewise with natural enemies.

Durrantia arcanella is a recurring pest insect of oil palm in Colombia. Because the biology and ecology of D. arcanella are unknown, it was proposed to determine the life cycle and foliar consumption under laboratory conditions. Furthermore, through sequential sampling for two and a half years, its population fluctuation and natural enemies were determined in Agustín Codazzi and El Copey (Cesar, Colombia). Also, temperature, precipitation, and relative humidity were registered. The life cycle of D. arcanella lasted 48.0 ± 10.1 days, the egg 8.0 ± 0.7 days, larva 24.2 ± 6.2 days, pre-pupa 1.5 ± 0.5 days, pupa 7.1 ± 0.9 days, and adult 7.2 ± 2.0 days. The larvae consumed 8.2 ± 5.3 cm2 of leaflets. Correlations were found between the population fluctuation in D. arcanella and the temperature in El Copey (ρ = −0.45; p < 0.0043), relative humidity in Codazzi (ρ = 0.33; p < 0.034), and with the natural control in both locations ((ρ = 0, 61; p < 0.000044) and (ρ = 0.42; p < 0.006)). These results suggest monitoring the pest populations in the second semester of the year and show the importance of promoting native natural enemies.

Resumen. El gusano cogollero, Spodoptera frugiperda (J.E. Smith), es el insecto plaga de mayor importancia económica debido a los daños que causa al maíz (Zea mays L.) alrededor del mundo. Se determinaron las especies de parasitoides de S. frugiperda y el grado de parasitismo natural en maíz de la Comarca Lagunera, ubicada en Coahuila y Durango, México. El parasitismo de huevos fue bajo, 4.7% en 2020 y 2.0% en 2021, principalmente por Trichogramma spp.; en larvas fue del 20.6% en 2020 y 59.7% en 2021. Se identificaron nueve especies de parasitoides de larvas: Chelonus insularis (Cresson), Chelonus cautus (Cresson), Pristomerus spinator (Fabricius), Campoletis sonorensis (Cameron), Aleiodes laphygmae (Vierechk), Ophion flavidus Brulle, Euplectrus platyhypenae Howard, Lespesia archippivora (Riley), y Archytas marmoratus (Townsend). Aleiodes laphygmae se considera un nuevo reporte para el estado de Durango, como parasitoide del gusano cogollero. Estos resultados son una contribución al conocimiento del parasitismo natural del gusano cogollero en la Comarca Lagunera, lo cual establece la base para futuros estudios sobre su control biológico. Abstract. The fall armyworm, Spodoptera frugiperda (J.E. Smith), is the insect pest of great economic importance because of damage to maize (Zea mays L.) worldwide. The parasitoid species of S. frugiperda and the degree of natural parasitism in maize from the Comarca Lagunera located at Coahuila and Durango, Mexico, were determined. Egg parasitism was low, 4.7% in 2020 and 2.0% in 2021, mostly because of Trichogramma spp. Larval parasitism was 20.6% in 2020 and 59.7% in 2021. Nine species of larval parasitoids identified were: Chelonus insularis (Cresson), Chelonus cautus (Cresson), Pristomerus spinator (Fabricius), Campoletis 1 Lepidoptera: Noctuidae.

La creciente demanda de las crasuláceas para uso ornamental ha provocado la extracción ilegal y alteración de sus hábitats. En apoyo a su conservación se han establecido centros de propagación, donde el manejo de diversos factores, como la presencia de insectos fitófagos, determina el desarrollo exitoso. Es necesario conocer la identidad de las plantas, de sus herbívoros y la biología de estos para poder manejarlos, considerando que las relaciones tróficas son específicas y que, bajo ciertas condiciones, algunos insectos afectan la producción de sus plantas hospederas. El objetivo de esta investigación fue identificar una larva fitófaga causante de daños en hojas de Sedum rubrotinctum, Crassula ovata, Aeonium decorum, Echeveria cante y Echeveria catorce que forman parte de la Colección Especial de Plantas Suculentas de la Universidad Autónoma Chapingo (CEPS-UACh), al mismo tiempo fueron realizadas observaciones sobre el ciclo de vida y la relación con sus plantas hospederas. El fitófago se identificó como Callophrys xami (Reakirt) (Lepidoptera: Lycaenidae), la mariposa sedosa verde mexicana. Los primeros huevecillos recién ovipositados fueron observados en junio, eclosionando una semana después. El daño de los últimos estadios larvales fue evidente en septiembre, pupando a mediados de octubre. Los adultos emergieron en la primera semana de noviembre.

... Table 3 shows the information on the studies carried out. Other organisms that participate in biological control are natural enemies, such as parasitoids, which have proven their importance as population regulators of S. frugiperda [75,76]. Spodoptera frugiperda have more than 100 species of parasitoids. ...
... In other states of Mexico, Meteorus laphygmae and Pristomerus spinator have been reported as parasitoid larvae with higher rates of parasitism in populations in Sinaloa (22.2%) and Michoacan (22.1%). P. spinator has also been found in Altamira, Tamaulipas with 10% parasitism [76]. ...
The strategies for controlling the insect pest Spodoptera frugiperda have been developing over the past four decades; however, the insecticide resistance and the remarkable adaptability of this insect have hindered its success. This review first analyzes the different chemical compounds currently available and the most promising options to control S. frugiperda. Then, we analyze the metabolites obtained from plant extracts with antifeedant, repellent, insecticide, or ovicide effects that could be environmentally friendly options for developing botanical S. frugiperda insecticides. Subsequently, we analyze the biological control based on the use of bacteria, viruses, fungi, and parasitoids against this pest. Finally, the use of sex pheromones to monitor this pest is analyzed. The advances reviewed could provide a wide panorama to guide the search for new pesticidal strategies but focused on environmental sustainability against S. frugiperda.
... In the Antarctic region, 37 Meteorus species have been reported, three of them parasitoids of fall armyworm ( Gutierrez et al. 2015, Yu et al. 2016. However, at Durango, only two morphospecies of Meteorus ( Garcia et al. 2013) and Meteorus laphygmae Viereck, 1913 species have been recorded (Bahena 2008). ...
Hymenoptera parasitoids Meteorus laphygmae Viereck, 1913 and M. arizonensisMuesebeck, 1923 were analyzed genetically to identify their variability in relation to species similar to them in morphology. Because of complexity in delimitation of the species, they have polymorphisms in color of the body and distinctive color patterns in the mesosome. A fragment of the cytochrome oxidase I (COI) gene was sequenced to learn the genetic distance between individuals. Maximum distribution of variance was found when two groups were formed: Group 1: Meteorus sp. Durango (two species = nine morphotypes) and Group 2: M. laphygmae ("predominant" species in Mexico) compared with external group Homolobus truncator Say, 1829, taxonomically similar to Meteorus (in Durango). The morphotypes of Meteorus sp. at Durango were genetically in a single group (0.0005 genetic distance between them), although taxonomically they belonged to two species (M. laphygmae and M. arizonensis). Group 1 differed from Group 2 of M. laphygmae (0.118) and H. truncator (0.206). This indicated the morphological characters of the two species of Meteorus did not coincide with genetic characters, which resulted in erroneous identification.
... Además de la familia Tachinidae y Eulophidae (Figura 3), estos se desarrollan desde huevo, larva, pupa (Figura 4) y adulto predominantes en cultivos de maíz . Dentro de la familia Ichneumonidae destacan las especies Campoletis sonorensis (Rodríguez-Mota et al., 2014), mientras que en la familia Braconidae, la especie Chelonus insularis es la que destaca con 86% de parasitismo (García-Gutiérrez et al., 2013). Algunos géneros de avispas parasitoides, tales como Meteorus y Euplectus, también incluyen especies parasíticas; adicionalmente se ha registrado que las especies Aphidius testaceipes y Cotesia marginiventris se han registrado como enemigos naturales de otros insectos plaga en el maíz . ...
... El estudio se realizó en ocho localidades que corresponden a cinco municipios [Santiago Papasquiaro, Pánuco de Coronado, Canatlán, Guadalupe Victoria y Durango, Dgo.] pertenecientes a la parte central, central oeste y sur del Estado de Durango. El área de estudio comprendió la región de los Valles, los Llanos y las Quebradas, con altitudes que van de 1,884 a 2,319 msnm con clima semiseco templado (García-Gutiérrez et al. 2013, González-Maldonado et al. 2014. Las colectas se realizaron en el ciclo primavera-verano 2015 y 2016, en cultivos de maíz. ...
The molecular characterization of three species of the genus Chelonus
was conducted for: [Ch. insularis Cresson 1865, Ch. cautus Cresson 1872 and Ch.
sonorensis Cameron 1887 (Hymenoptera: Braconidae) - nominal species],
parasitoids of the armyworm Spodoptera frugiperda (J.E. Smith) (Lepidoptera:
Noctuidae) collected in maize (Zea mays L.), which are distributed in Durango and in
other states of Mexico. The extraction and amplification of DNA was by PCR, as well
as the sequencing of a fragment of the cytochrome c oxidase subunit I, to determine
the genetic variability within and between individuals of the same species.
Genetically, the distances between the species Ch. insularis and Ch. sonorensis, was
very small (0.3%), indicating they probably belong to the same lineage (species),
while Ch. cautus had a genetic distance from the other species to 17.8%, which
indicates great genetic differentiation. These results indicated the genetic variability
that exists within and between these species is probably due to evolutionary changes.
This was reinforced after Bayesian and maximum-likelihood analyzes that indicate
that in the maize region of Durango, Ch. insularis and Ch. sonorensis belong to the
same lineage with support in the groups of more than 80%, while Ch. cautus belongs
in another cluster.
