“…Para disminuir su incidencia se utilizan principalmente insecticidas químicos (Barreto Carbajal et al, 2022), sin considerar que su uso indiscriminado puede generar daños a la salud de los agricultores y consumidores, los cuales han sido documentados en Ecuador (Fernández Aravena, 2021;Vargas Sunta y Moyano Calero, 2022). Adicionalmente causan desequilibrios ecológicos de algunas plagas agrícolas derivándose vertiginosos incrementos poblacionales, problemas de resistencia, entre otras (Zelaya-Molina et al, 2022).…”

El maíz es considerado el tercer cultivo de grano más importante del mundo debido a su interés económico, alimentario e industrial. A lo largo de su fenología este cultivo es atacado por plagas y enfermedades, que pueden generar efectos adversos sobre la producción. Para el control de estos problemas, generalmente se acude al manejo convencional, los cuales ocasionan desequilibrios ecológicos. Por esta razón, es necesario considerar alternativas sostenibles fundamentadas en el conocimiento de la entomofauna benéfica. Esta investigación tuvo por objetivo realizar un análisis prospectivo de los coccinélidos asociados al cultivo de maíz en el cantón Santa Ana, Ecuador. Para su efecto, se evaluaron los coccinélidos presentes en dos condiciones distintas: con y sin aplicación de insecticida. Se utilizaron cinco técnicas de muestreo, de acuerdo con el protocolo de investigación, y se procedió con la clasificación taxonómica. Los datos fueron interpretados mediante estadística descriptiva; además, se valoró la diversidad alfa y beta. En el estudio se encontraron 297 individuos, congregados a: 1 orden,1 familia, 13 géneros y 11 especies. La mayor abundancia se presentó en condiciones no intervenidas, determinándose que la técnica de trampeo más eficiente para su captura fueron las trampas cromáticas. Este tipo de investigación es importante para derivar programas de control biológico en cultivos de importancia económica.

“…In agricultural production, producers have been facing pest control, in particular, those with greater adaptability, standing out among them phytophagous insects that are difficult to combat (Saldamando and Marquez, 2012;Brunetti et al, 2022;Pérez et al, 2003;Extremera et al, 2004;Armstrong, 1994), state that the genus Spodoptera sp., is found within the Noctuidae family, geographically located in North America and Latin America, France, Italy, Black Sea, Balkans, England, North and Southern Africa, the Middle East, the Iberian Peninsula, and Germany (Kergoat et al, 2021;Zelaya et al, 2022).…”

Background: The research focused on evaluating the biological and reproductive parameters of the species Spodoptera sunia with the introduction of field genetic material, in the Noctuid Insect Breeding Laboratory. Methods: The study was pre-experimental using three treatments with 30 individuals and three repetitions. The individuals were collected from the field, transferred to the laboratory under semi-controlled conditions of temperature and humidity, later they were quarantined for up to three generations for the assembly of the test where the crossing was carried out. In the measurement of the biological and reproductive parameters. Results: The results of the treatments showed that the biological and reproductive parameters in relation to the number of pupae were T2 34 males and 26 females, T3 was 33 males, and 27 females, T1 obtained 27 males and 33 females. The average weight in female T1 was 0.2112 mg and T2 was 0.2401 mg. The number of eggs in T1 in nine days oviposited 196 egg masses, in T2 in seven days 59 egg masses were oviposited, and in T3 160 egg masses were oviposited. In the length parameter in mm T3 obtained 30 mm in larval development, T1 and T2 obtained 27 mm. Finally, in the development stages, the number of days was for T1 and T2, 24 days and for T3 18 days. In the adult stages T1 and T2 it was 12 days and for T3 10 days. In the egg stage in the three treatments it was three days and the pupal stage was eight days. Conclusions: It is concluded that T2 and T3 presented the most optimal results. It is recommended to introduce genetic material every six months to maintain a good production of larvae of the species under study in laboratories for the production and reproduction of insect breeding.

“…It is worth mentioning that the genus Spodoptera sp. (Guenée) (Lepidoptera: Noctuidae) is a prominent member of the Noctuidae family, with geographical presence spanning across North America, Latin America, France, Italy, the Black Sea region, the Balkans, England, North and Southern Africa, the Middle East, the Iberian Peninsula, and Germany ( Kergoat et al ., 2021 ; Zelaya et al ., 2022 ).…”

Background The research focused on evaluating the biological and reproductive parameters of the species Spodoptera sunia with the introduction of field genetic material, in the Noctuid Insect Breeding Laboratory. Methods The experiment consisted of three treatments and three repetitions involving 30 individuals each. Field-collected S. sunia population was reared in the laboratory under semi-controlled conditions of temperature and humidity for three generations. The progeny of the third generation was crossed with the laboratory population and the resulting progeny was observed for growth and reproductive fitness. Results The results revealed that the hybrid progeny (T3) has a sex ratio (F: M) of 0.82, as against 1.22 and 0.76 observed in the field (T1) and lab populations (T2) respectively. The T1 females oviposited 196 egg masses as against 160 and 59 egg masses by T3 and T2 females respectively. The larval growth was more in hybrid progeny with shorter larval duration. However, no variation was observed in the incubation and pupal periods. Conclusions Since the most optimal results were obtained in T2 and T3, it is recommended to introduce genetic material every six months to maintain a good laboratory population of the insect host under study and better breeding of its natural enemies.
