A key to some Frankliniella (Thysanoptera: Thripidae) larvae found in Florida with descriptions of the first instar of select species

thrips, immature, identification, morphology, host plant, COI mitochondrial geneAbstract
Few publications exist toward the identification of larval thrips. As a result, researchers and practitioners often are unable to report larval species data or may misinterpret what is a host plant when adults of multiple species are collected. Therefore, we conducted repetitive plant sampling and detailed examination of larvae with adults, which revealed morphological differences of some undescribed Frankliniella (Thysanoptera: Thripidae) larvae. The morphological differences were confirmed by non-destructive DNA extraction, PCR, and sequencing of the COI mitochondrial gene. A larva II morphological key to 7 Frankliniella species found in Florida is presented with new larval descriptions of 4 species.
Resumen
Existen pocas publicaciones sobre la identificación de larvas de los trips. Como resultado, los investigadores y los técnicos a menudo no puedan reportar datos sobre las especies de larvas o pueden mal interpretar lo que es una planta hospedera cuando se recolectan múltiples especies de adultos. Por lo tanto, se realizó un muestreo repetitivo de plantas y se examinó en detalle las larvas con los adultos que revelaron diferencias morfológicas de las larvas no descritas de algunas especies de Frankliniella (Thysanoptera: Thripidae). Las diferencias morfológicas fueron confirmadas por la extracción no destructiva de ADN, PCR y secuenciación del gen mitocondrial COI. Se presenta una clave morfológica de las larvas II de 7 especies de Frankliniella que se encuentran en la Florida con nuevas descripciones de larvas para 4 especies.
