Biology of Lycoriella ingenua and Bradysia impatiens (Diptera: Sciaridae)
Lycoriella (Lycoriella) ingenua (Dufour, 1839) and Bradysia impatiens (Johannsen, 1912) (Diptera: Sciaridae) are two black fungus gnats species studied that harm Pinus montezumae (Lamb, 1832) seedlings in forestry nurseries.

| description | Lycoriella (Lycoriella) ingenua (Dufour, 1839) and Bradysia impatiens (Johannsen, 1912) (Diptera: Sciaridae) are two black fungus gnats species studied that harm Pinus montezumae (Lamb, 1832) seedlings in forestry nurseries. These dipterous were morphological and molecularly identified and are mentioned for the first time as a pest in Mexico’s forestry nurseries. The proportion of sexes to Lycoriella ingenua was of one male per 1.25 females; to characterize this species eggs, pupas, larvae and cephalic capsules were measured. The morphometric data of body length and cephalic cage width of larvae through the hierarchical conglomerated method determined the larval instars of the species. For B. impatiens there are 2.4 females per male. In the definition of the larval instars, the best parameter was that of the cephalic capsule. Both species presented four larval instars. Both species were bred under lab conditions at 21 °C ± 2 °C. The whole cycle of L. ingenua required 30.5 ± 3.5 days. For B. impatiens the time to conclude biological cycles was of 27.5 ± 2.5 days. It was determined that both species of larvae consume Pinus montezumae root. The fungi associated to larvae and fungi of both species were identified. Fusarium circinatum was the most important and it is registered for the first time in nurseries of Pinus montezumae; this species was morphological and molecularly identified. |

Se estudiaron dos especies de mosquito fungoso negro, Lycoriella (Lycoriella) ingenua (Dufour, 1839) y Bradysia impatiens (Johannsen, 1912) (Diptera: Sciaridae), que causan daño a plántulas de Pinus montezumae (Lamb, 1832) en viveros forestales. Estos dípteros se identificaron morfológicamente y por métodos moleculares y se citan por primera vez como plaga en viveros forestales de México. La proporción sexual para L. ingenua fue de un macho por cada 1.25 hembras; para caracterizar esta especie se midieron huevos, pupas, larvas y cápsulas cefálicas. Con los datos morfométricos de longitud de cuerpo y ancho de la cápsula cefálica de larvas y mediante el método de conglomerados jerárquicos se determinaron los estadios larvarios de la especie. Para B. impatiens por cada macho existen 2.4 hembras. En la distinción de los estadios larvarios, el mejor parámetro fue el ancho de cápsula cefálica. Ambas especies presentaron cuatro estadios larvarios. Las dos especies se criaron en laboratorio a 21 ºC ± 2 ºC. El ciclo completo de L. ingenua requirió de 30.5 días ± 3.5 días. Para B. impatiens el tiempo para concluir ciclos biológicos fue de 27.5 días ± 2.5 días. Se determinó que las larvas de ambas especies consumen la raíz de Pinus montezumae. Se identificaron los hongos asociados a larvas y adultos de ambas especies, Fusarium circinatum fue el más importante y se registra por primera vez en viveros de P. montezumae; esta especie de hongo se identificó mediante morfología y por métodos moleculares.
