“…La especie M. latipes es un insecto polífago y voraz que se alimenta de pastos forrajeros, avena, algodón, soya, trigo, maíz, sorgo, alfalfa, caña de azúcar, arroz y algunas plantas silvestres (Lourenção et al, 1982;Cruz y Santos, 1983;Lübeck et al, 1995;Zanuncio et al, 1995;Gallo et al, 2002;Kahl et al, 2018). En el Continente de América, su distribución abarca del norte de Canadá hasta Brazil (Cruz y Santos, 1983;Silva et al, 1991;Assunção-Albuquerque et al, 2010;Claudino et al, 2021). En el presente trabajo se reporta por primera vez en el estado de Veracruz, México al lepidóptero M. latipes alimentándose de P. maximum cv.…”

“…La fase larvaria del falso medidor puede tener entre seis a siete estadios en un lapso de 15 a 18 d y su ciclo biológico dura alrededor de 50 d (Gallo et al, 2002;Kahl et al, 2018). En el último estadio, la larva se convierte en pupa entre dos hojas de la hospedera para formar un cocón, donde completa su metamorfosis hasta emerger una palomilla entre 40 a 42 mm de largo, y presenta dos generaciones por año (Assunção-Albuquerque et al, 2010), la forma de pupar coincide con las observaciones de campo durante la recolecta.…”

“…Ambos pastos mejorados son resistentes al salivazo Aeneolania postica, pero al ser cultivados como monocultivos son más susceptibles a ser devastados por otras plagas (UNIPASTO, 2017; Velasco et al, 2018). La implementación de buenas prácticas agrícolas, como la rotación de cultivos y los policultivos permiten disminuir la ocurrencia de éstas (Zepeda-Jazo, 2018), por ejemplo Mocis latipes o el falso medidor de los pastos tiene importancia económica en Brasil, Cuba, Venezuela y Argentina con altas infestaciones en P. maximum y Cynodon plectostachyus, en bajas poblaciones en Pennisetum purpureum, Brachiaria decumbens, B. decumbens, Digitaria insularis, Setaria italica y Cenchrus echinatus (Silva y Neves, 1984;Assunção-Albuquerque et al, 2010;Claudino et al, 2021).…”

Background. Cultivation of forage grasses is an important component in the dual-purpose cattle production system; however, insect pests can decrease fresh material yields. Objective. To taxonomically identify the causal agent that damages the cultivars Panicum maximum (Jacq.) cv. Mombasa and Panicum maximum cv. Zuri. Methodology. In two locations in the central region of Veracruz, specimens of an insect in the larval and pupal stages were collected using the quadrant method in an area of 50 ha. Subsequently, in the laboratory, larvae were boiled for two minutes and preserved in 70% alcohol. Meanwhile, pupae were placed in a brood chamber with foliage to obtain adults and to extract their genitalia, which represents the most important morphological structure for the identification of a species. Results. The total number of collected larvae was 650, and 65 pupae, all reaching the adult stage. Based on the taxonomic morphology, the species Mocis latipes or striped grassworm was determined. Damage was estimated at approximately 40% per hectare. Implications. Correct identification of the pest insect allows the implementation of a strategy for proper management. Conclusion. The species M. latipes was identified in forage grasses P. maximum cv. Mombasa and P. maximum cv. Zuri in Veracruz.

“…The genus Mocis (Lepidoptera: Noctuidae) carries some important polyphagous insects that affect several cultures in many countries of the world [ 1 ]. These species are widespread throughout the American continent, impacting grasses, wheat, corn, rice, cotton, coffee, soybeans, and peanuts [ 2 ].…”

In this report, we described the genome of a novel baculovirus isolated from the monocot insect pest Mocis latipes, the striped grass looper. The genome has 134,272 bp in length with a G + C content of 38.3%. Based on the concatenated sequence of the 38 baculovirus core genes, we found that the virus is a betabaculovirus closely related to the noctuid-infecting betabaculoviruses including Pseudaletia unipuncta granulovirus (PsunGV), Trichoplusia ni granulovirus (TnGV), Helicoverpa armigera granulovirus (HearGV), and Xestia c-nigrum granulovirus (XecnGV). The virus may constitute a new Betabaculovirus species tentatively named Mocis latipes granulovirus (MolaGV). After gene content analysis, five open reading frames (ORFs) were found to be unique to MolaGV and several auxiliary genes were found including iap-3, iap-5, bro-a, bro-b, and three enhancins. The virus genome lacked both chitinase and cathepsin. We then looked at the evolutionary history of the enhancin gene and found that betabaculovirus acquired this gene from an alphabaculovirus followed by several duplication events. Gene duplication also happened to an endonuclease-like gene. Genomic and gene content analyses revealed both a strict collinearity and gene expansion into the genome of the MolaGV-related species. We also characterized the granulin gene using a recombinant Autographa californica multiple nucleopolyhedrovirus (AcMNPV) and found that occlusion bodies were produced into the nucleus of infected cells and presented a polyhedral shape and no occluded virions within. Overall, betabaculovirus genome sequencing is of importance to the field as few genomes are publicly accessible. Mocis latipes is a secondary pest of maize, rice, and wheat crops in Brazil. Certainly, both the discovery and description of novel baculoviruses may lead to development of greener and safer pesticides in order to counteract and effectively control crop damage-causing insect populations
