Tuta absoluta caterpillars were identified in the field according to 3 criteria: characteristic leaf mines, body form and size as described in USDA (2011), and a distinctive dark prothoracic
band as described in Roditakis et al.
The potential effects of male exposure in the response of the L3 prothoracic
auditory interneuron are unknown.
Pronotal lateral lobe polished dark brown to black; light ventro-posterior patch widest at posterior pronotal margin, extends tapering forwards to prothoracic
Length of prothoracic
spiracle: short (until 0.17mm) (0) (Figure 33); medium (from 0.21-0.22mm) (1) (Figure 34); long (more than 0.29mm) (2) (Figure 35)

plate in mylabrid (Bruchidae) larvae (A study in adaptation).
Additional evidence for the masking role and decreased capacity in aged cells of Sia were obtained from insect tissue, prothoracic
glands, in Galleria mellonella (Lepidoptera).

gland for ecdysone biosynthesis," Developmental Biology, vol.
In addition, ecdysteroids themselves play a role in their ownbiosynthesis via a feedback regulation of the PTTHaxis in the insect brain, and via direct action on the ecdysteroid-producing (prothoracic
glands and/or endocrine organs like ovaries) (Belles and Piulack, 2015).
Inhibition of insect development by simultaneous action of prothoracic
gland hormone and juvenile hormone.
