| morphology of the integumentary structures in the nymph of lace bug, stephanitis typica (hemiptera: tingidae). | the nymphs of the lace bug stephanitis typica possess unsegmented, slender, integumentary processes. they are arranged chiefly in three rows on the mid-dorsal and lateral sides. the surface ultrastructure of the integumentary process reveals three types of sensilla, namely, companiform sensilla at the tip of the integumentary process having a probable proprioceptive function, oar-shaped wind and gravity sensilla, and pegs supposed to be hygroscopic. | 2004 | 15077900 |
