Frankliniella cephalica (D. L. Crawford) ( Fig. 3B )

DESCRIPTION, LARVA II

Head with the D1–D4 setae apically pointed: D1 setae 10–15 µm long; D2 12–18 µm long; D3 12–15 µm long, and D4 22–25 µm long. The abdominal setae,tergites II–VII,are broadly pointed.The D1 setae of abdominal tergite IX are blunt and D2 pointed. The dorsal abdominal plaques segments II–VI with few poorly developed or rounded microtrichia anterior of the dorsal setae; most plaques anterior of the dorsal setae segments VII and VIII with rounded microtrichia.Occasionally,a few developed or point- ed 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 longer than the basal width of the D1 setae;approximately 12–15 teeth present between the D2 setae.The ventral posteromarginal teeth are minute about 1/3 the size of the dorsal teeth. Tergite X with a transverse dark band that extends to the campaniform sensilla of the tergite.

DESCRIPTION, LARVA I

Head with the D1–D4 setae apically pointed. Dorsal thoracic and abdominal setae I–VIII apically pointed. Tergite IX D1 and D2 setae blunt. Tergite X D1 setae blunt. Meso- and metanotal plaques, anterior to the posteromarginal row of major setae with rounded microtrichia and those posterior of the setal row are crescent shaped and lack microtrichia. Tergal plaques abdominal segments I–VIII with microtrichia. Approximately 10–12 thin posteromarginal sclerotized teeth between the D2 setae of tergite IX. No sclerotized teeth lie within the dark band between the D1 setae of the tergite. Terga IX and X with dark bands similar to the larva II.
