“…Numerous pathogens, including viruses, fungi, protozoa, nematodes and bacteria, have been associated with Fall armyworm (Gardner, Noblet, & Schwehr, 1984), but only a few cause epizootics to the pest (Behle & Popham, 2012;Garcia, Raetano, & Leite, 2008;Gómez, Guevara, Cuartas, Espinel, & Villamizar, 2013;Negrisoli, Garcia, Negrisoli, Bernardi, & da Silva, 2010;Polanczyk, Silva, & Fiuza, 2000;Salvadori et al, 2012 tested here has previously shown to be highly virulent against other lepidopteran larvae such as the second instar larvae of the cereal stem borers, Chilo partellus (Swinhoe) (Lepidoptera: Pyralidae) and…”

Maize is a major staple food for over 300 million people in sub-Saharan Africa.Sustainable productivity of this primary crop has been recently threatened by Fall armyworm (FAW), Spodoptera frugiperda invasion. Due to lack of environmentally safe management strategies, immediate responses by growers and governments to tackle FAW are based on rampant use of pesticides. Looking for efficient biopesticides, twenty entomopathogenic fungal isolates (14 Metarhizium anisopliae and 6Beauveria bassiana) were screened for their efficacy against eggs and second instar larvae of FAW. A single discriminating concentration of 1 × 10 8 conidia ml −1 and four replicates per treatment were used in all experiments. Isolates were assessed for their ability to cause mortality of FAW second instar larvae, eggs and the neonate larvae that emerged from treated eggs. Among the isolates tested, only B. bassiana ICIPE 676 caused moderate mortality of 30% to second instar larvae. Metarhizium anisopliae ICIPE 78, ICIPE 40 and ICIPE 20 caused egg mortalities of 87.0%, 83.0% and 79.5%, respectively, and M. anisopliae ICIPE 41 and ICIPE 7 outperformed all the others by causing 96.5% and 93.7% mortality to the neonate larvae, respectively. The cumulated mortality of eggs and neonates was highest with M. anisopliae ICIPE 41 (97.5%), followed by M. anisopliae ICIPE 7, 655, 40, 20 and 78 with total mortality of 96.0%, 95.0%, 93.5%, 93.0% and 92.0%, respectively. These isolates with high cumulated mortality (≥92%), especially ICIPE 78 and 7, which are already commercialized for spider mites and ticks control respectively, would be good candidates for development as biopesticides for management of FAW in Africa if further evidence of their efficacy is obtained in the field.

“…Moreover, biopesticidal formulations based on those viruses were obtained and field trials revealed that the isolates were effective in controlling the pest and keep the pest population below the economic damage threshold. The efficacy in controlling the pest were similar to that of chemical insecticides when treatment of plots was up to 22 days post emergence of the pest [ 137 ]. These studies allowed the development of a SfMNPV-based commercial formulation for the biological control of S. frugiperda by CORPOICA, which is in the process of registration [ 138 ].…”

Baculoviruses are known to regulate many insect populations in nature. Their host-specificity is very high, usually restricted to a single or a few closely related insect species. They are amongst the safest pesticides, with no or negligible effects on non-target organisms, including beneficial insects, vertebrates and plants. Baculovirus-based pesticides are compatible with integrated pest management strategies and the expansion of their application will significantly reduce the risks associated with the use of synthetic chemical insecticides. Several successful baculovirus-based pest control programs have taken place in Latin American countries. Sustainable agriculture (a trend promoted by state authorities in most Latin American countries) will benefit from the wider use of registered viral pesticides and new viral products that are in the process of registration and others in the applied research pipeline. The success of baculovirus-based control programs depends upon collaborative efforts among government and research institutions, growers associations, and private companies, which realize the importance of using strategies that protect human health and the environment at large. Initiatives to develop new regulations that promote the use of this type of ecological alternatives tailored to different local conditions and farming systems are underway.

“…El bioplaguicida recién manufacturado presentó un contenido de mohos contaminantes de 3,67 x 10 4 UFC/g de producto y un contenido de levaduras de 1,27 x 10 4 UFC/g (tabla 3), valores que disminuyeron a través del tiempo de almacenamiento a las diferentes temperaturas (tabla 3). En general, los tres tipos de contaminantes cuantificados en el producto (bacterias, mohos y levaduras) se mantuvieron durante los 15 meses de almacenamiento para las tres temperaturas, en valores inferiores al límite máximo de aceptación establecido en la caracterización del producto (10 6 UFC/g) (Gómez et al, 2013), lo que permite sugerir que este parámetro fue estable durante el tiempo y no afectó la calidad microbiológica del bioplaguicida durante su vida de anaquel.…”

<div><p>Con un aislamiento colombiano del nucleopoliedrovirus de Spodptera frugiperda SfNPV003 se desarrolló una formulación en polvo mediante un proceso de microencapsulación con un polímero del ácido metacrílico, el cual aumentó la fotoestabilidad del virus. Con el fin de generar las recomendaciones para el uso de este bioplaguicida, el objetivo de la presente investigación fue establecer la compatibilidad in vitro con los productos químicos (insecticidas y fungicidas) que se utilizan con mayor frecuencia en el cultivo de maíz y determinar la estabilidad del producto durante 15 meses de almacenamiento a 8, 18 y 28 °C. El virus fue compatible con ocho agroquímicos evaluados y presentó una actividad insecticida superior a 80%. Cuando el bioplaguicida fue almacenado a 8, 18 y 28 °C, la actividad insecticida y el contenido de contaminantes se mantuvieron dentro de los límites de aceptación establecidos para estos parámetros. Con base en los resultados obtenidos se recomendó el almacenamiento del bioplaguicida a base del SfNPV003 en temperaturas inferiores a 28 °C, lo que garantiza la calidad del producto durante mínimo 17 meses, tiempo adecuado para su distribución y uso.</p></div><p> </p>
