“…Finalmente, Pinto et al (2014), identifican a Phanerotoma bennetti [Muesebeck, 1955] (Hymenoptera, Braconidae, Cheloninae) como un nuevo controlador de H. grandella e H. ferrealis en árboles de andiroba (Carapa procera DC), siendo un aporte significativo e importante para ser implementado como parte de la gestión en el manejo integrado de plagas en meliácea, aunque se deba estudiar los enemigos naturales que restrinjan el accionar del insecto plaga. CONCLUSIONES Se destaca que la valoración de métodos en el control del taladrador de la meliáceas se ha centrado en la bús-queda de alternativas económicamente viable y ecológica-mente sostenible en relación al medio ambiente, tomando mayor auge la tipificación de elementos importantes dentro de un mismo ecosistema con principios activos que certifiquen el control silvicultural y biológico del insecto plaga en plantaciones forestales y agroforestales de meliáceas.…”

SUMMARYIn the present review article, a recapitulation of recent research made with the purpose of decreasing the negative effect produced by the insects Hypsipyla grandella and Hypsipyla robusta (shoot borers) on seedlings of the Meliaceae family is presented, highlighting the mahogany (Swietenia macrophylla) and the cedar (Cedrela odorata) that are considered of high commercial importance due to the structure and quality of their wood in the forestry industry. Hypsipyla spp. has been identified as a potential plague and of commercial interest, as it attacks plants in their first life stages. This attack induces excessive branching, deformation of the stem and in the worst cases the death of the affected seedlings in monospecific plantations. The use of chemical agents (insecticides and pheromones), shade regulation on plantations, implementation of good forestry practices, biological control and the combination of plants with allelopathic principles against the plague in forestry cultures are some of the alternatives evaluated in situ and ex situ for the control or extermination of this plague that for many years has been the object of study of researchers.Key words: Cedrela odorata, commercial importance, monospecific plantations, pests, Swietenia macrophylla. RESUMENEn el presente artículo de revisión se hace una recapitulación de investigaciones recientes que se han realizado con el propósito de disminuir el efecto negativo producido por los insectos Hypsipyla grandella e Hypsipyla robusta (taladrador de los brotes tiernos) en plántulas pertenecientes a la familia de las meliáceas, destacando la caoba (Swietenia macrophylla) y el cedro (Cedrela odorata), consideradas de suma importancia comercial por su estructura y calidad de la madera en la industria forestal, se ha identificado a Hypsipyla spp. como una plaga potencial y de interés comercial por atacar a las plantas en los primeros estadios de vida, puesto que el ataque induce a la formación excesiva de ramas, malformación de fustes y, en el peor de los casos, la muerte de las plántulas afectadas en plantaciones monoespecíficas, desde el uso de agentes químicos (insecticida y feromonas), manejo de la sombra en plantaciones, implementación de buenas prácticas silviculturales, control biológico y la combinación de plantas con principios alelopáticos hacia la plaga en cultivos forestales, son algunas de las alternativas evaluadas in situ y ex situ a fin de controlar o erradicar la plaga que por muchos años ha sido objeto de estudio por investigadores.Palabras clave: Cedrela odorata, importancia comercial, plagas, plantaciones monoespecíficas, Swietenia macrophylla. INTRODUCCIÓNLos taladradores Hypsipyla grandella [Zeller, 1848] e Hypsipyla robusta [Moore, 1886] (Lepidoptera: Pyralidae) son plagas potenciales y económicamente importantes porque atacan los brotes tiernos terminales y en algunas ocasiones el fuste de los individuos arbóreos pertenecientes a la familia de las meliáceas (importantes en los mercados madereros a nivel mundial) como la caoba (Sw...

“…Atualmente, não existem estratégias para controlar a incidência de ataques da lagarta H. grandella (Lunz et al, 2009). Algumas tentativas com o controle biológico, apesar de serem promissoras, não têm sido eficazes (Pinto et al, 2014), e as adubações com potássio (Calixto et al, 2015) e cálcio e boro também têm sido alternativas estudadas (Silva Junior et al, 2014).…”

Resumo -O objetivo deste trabalho foi avaliar as características das plantas de cedro (Cedrela fissilis) atacadas por pragas, os danos causados e as condições em que estes foram mais pronunciados. Realizou-se um censo dos indivíduos de cedro por caminhamento em uma área total de 5,55 ha de floresta nativa, no município de Silveira Martins, RS. Cedros com altura total superior a 15 cm e diâmetro do coleto inferior a 12 cm foram medidos, e foi avaliado seu estado fitossanitário em relação às pragas. Foram confeccionados histogramas de frequência de diâmetro do coleto, e analisou-se a relação hipsométrica das árvores atacadas e sadias por meio da análise de covariância. Para a análise espacial dos indivíduos, foram feitos mapas de densidade de cedros e mapas de taxa de risco do serrador e da mariposa. As árvores com maior probabilidade de ataque foram aquelas com diâmetro de coleto entre 2 e 6 cm. As clareiras ou áreas com baixa densidade total de árvores foram as áreas mais suscetíveis aos ataques da lagarta Hypsipyla grandella, e locais com elevada densidade de indivíduos cujo diâmetro de coleto mede entre 8 e 12 cm são os mais suscetíveis ao ataque de larvas do Oncideres sp.Termos para indexação: Cedrela fissilis, Hypsipyla grandella, Oncideres, mariposa, serrador. Susceptibility of cedar to pest attack in seasonally deciduous forestAbstract -The objective of this work was to evaluate the characteristics of cedar plants (Cedrela fissilis) attacked by pests, the resultant damages, and the conditions in which the damage was more pronounced. A census of cedar individuals was conducted by going through a total area of 5.55 hectares of native forest in the municipality of Silveira Martins, in the state of Rio Grande do Sul, Brazil. Cedars with total height greater than 15 cm and collar diameter less than 12 cm were measured, and their pest status was evaluated. Frequency histograms of the collar diameter were made, and the hypsometric relationship of attacked and healthy trees was evaluated by analysis of covariance. For the spatial analysis of individuals, maps of cedar density and maps for risk assessment of sawyer beetle and moth were made. Trees with the greatest probability of being attacked were those with collar diameter between 2 and 6 cm. The clearings and areas with low total density of trees were the most susceptible ones to attacks of the Hypsipyla grandella caterpillar, and locations with high density of individuals whose collar diameter is between 8 and 12 cm are the most susceptible ones to the attacks of Oncideres sp. larvae.

“…The genus Diolcogaster belongs to the subfamily Microgastrinae (Hymenoptera: Braconidae) which comprises 2,700+ described species (Yu et al, 2016;Whitfield et al, 2018) and many thousands of additional undescribed ones (Rodriguez et al, 2013;Fernández-Triana and Boudreault, 2016;Fernández-Triana and van Atcherberg, 2017;Moghaddam and Mokhtari, 2017;. Microgastrinae is the single most important group of parasitoid wasps attacking caterpillars (Whitfield, 1997;Avila et al, 2013;Fernández-Triana et al, 2014;Pereira et al, 2015;Fiaboe et al, 2017), with many species used or being considered as biocontrol agents against lepidopteran pests in agriculture and forestry (Yeargan and Braman, 1986;Smith et al, 2013;Pinto et al, 2014). Diolcogaster is currently the seventh largest genus of Microgastrinae, with 101 species described worldwide (Zeng et al, 2011;Fernández-Triana, 2015;Fernández-Triana et al, 2016;Moghaddam et al, 2019) and hundreds awaiting description.…”

A new species of Diolcogaster (Hymenoptera: Braconidae) is described and illustrated. Additionally, its position within the recently published key to New World species of the xanthaspis species-group (to which the described Diolcogaster belongs) is provided. The gregarious larval parasitoid Diolcogaster choi sp. nov. was collected in Maringá, Paraná State, Brazil. This natural enemy was recovered from a caterpillar of Hypercompe cunigunda (Stoll, 1781) (Lepidoptera: Erebidae) that was feeding on plant of passionflower, Passiflora edulis Sims (Passifloraceae). The fauna of the xanthaspis group in the New World now includes five species, including the new species from Brazil described in this paper. Diolcogaster choi sp. nov. differs anatomically, and is morphologically diagnosed, from all other known member of the xanthaspis group of the genus Diolcogaster, to which it belongs. The species also differs in recorded host, and its DNA barcode appears to be distinctive among described Diolcogaster.
