Ultrastructure of the invasive insect Corythucha marmorata Uhler,1878(Hemiptera:Tingidae)from egg to adult
In this study,the external morphology of Corythucha marmorata Uhler,1878(Hemiptera:Tingidae)was examined by scanning electron microscopy,with emphasis on the ontogenetic changes of the integument ultrastructures from eggs,nymphs to adults.The surface of the eggs is smooth,with crests and honeycomb shape cells around operculum.In the nymphs,the antennae of the first to third instars of C.marmorata,consist of only 3 segments,and the flagellum splits into 2 flagellomeres from the fourth instar nymphs to the adult;5 morphological types of sensilla were identified on the antennae:Sensilla Trichodea 1,Sensilla Trichodea 2,Sensilla Basiconica 1,Sensilla Basiconica 2,Sensilla Basiconica 3;4 types of projections increased in number during ontogeny:scale-like,triangular,claviform setae,and short-stalked mushroom-shaped projections;the integumentary tubercles of the first instar differed from those of the second to fifth instars,while the structure of the latter remained the same,but became more branched and longer.The results could help in the early identification of the invasive lace bug and provide more data for use in phylogenetic analyses.
