Frankliniella insularis (Franklin) ( Fig. 3C )

DESCRIPTION, LARVA II

Head with D1–D4 setae broadly pointed: D1 setae 20–23 µm long; D2 setae 25–30 µm long; D3 setae 20–30 µm long, and D4 setae 27–37 µm long. All the abdominal tergal setae are broadly pointed apically. The abdominal plaques segments II–VII with few poorly developed or rounded microtrichia anterior of the dorsal setae; those on VIII are more abundant. Sometimes a few pointed microtrichia present on tergite VIII. Tergite IX with a darkened band in which the anterior margin extends anteriorly about the diameter of a D1 setal socket. The posteromarginal teeth tergite IX are about the same length as the basal width of the D1 setae; approximately 18–21 teeth present between the D2 setae. The ventral posteromarginal teeth are minute about 1/2 the size of the dorsal teeth. Tergite X with a transverse dark band that extends to the campaniform sensilla of the tergite.
