dc.description.abstractLeucoptera coffeella –coffee leaf miner- is one of the principal pests of coffee in Puerto Rico. In Puerto Rico have been reported 16 species of parasitoids over larvae of L. coffeella being Mirax insularis the parasitoid with higher rates of parasitation. In current researches are not recorded closer estimates of their reproductive potential or parasitation on L. coffeella; for this reason, it is important to confirm the presence of M. insularis, estimating the percentage of population with the other species of parasitoids and their reproductive potential. The results confirm that M. insularis is the most abundant parasitoid in the three neighborhoods evaluated. Two pairs of M. insularis are able parasitize 5% of larvae Instar 1% and 7% of larvae Instar 2. The level of parasitation in laboratory studies was: 27% and 35% using parasitoids 60 and 80 respectively, on larvae Instar 2 per experimental unit of 10 trees of coffee.en_US
dc.description.abstractEl minador del café Leucoptera coffeella, es una de las plagas principales del café en Puerto Rico. En Puerto Rico se han reportado 16 especies de parasitoides en larvas de L. coffeella, siendo Mirax insularis el parasitoide con mayores índices de parasitación. En investigaciones recientes no se registran estimados aproximados de su potencial reproductivo o parasitación sobre L. coffeella. Por esta razón se consideró importante confirmar la presencia de M. insularis, estimar su porcentaje poblacional respecto a otras especies de parasitoides y su potencial reproductivo. Los resultados que obtenidos confirman que M. insularis es el parasitoide más abundante en los tres barrios evaluados. Dos parejas de M. insularis son capaces de parasitar el 5% de larvas Instar 1 y el 7% de larvas Instar 2. El nivel de parasitación en estudios de laboratorio fue: 27% y 35% empleando 60 y 80 parasitoides respectivamente, sobre larvas Instar 2 por cada unidad experimental de 10 arbolitos de café.en_US
