Última Analysis of nucleus activity in malpighian tubules of Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae) larvae by critical electrolyte concentration Neotropical Entomology Fermino,Fábio; Conte,Hélio; Falco,José R P. Diatraea saccharalis (Fabricius) has cryptonephridial type Malphigian tubules (MT). This type of MT is characterized by the penetration of the distal part of the MT into the external walls of the rectum, which is usually lined with a perinephral membrane. The MT is divided into three differentiated regions: proximal, middle and distal. In this study, our objective was to compare the nuclear activities of each one of the three regions of the D. saccharalis MT by using a nuclear basophilic technique and critical electrolyte concentration with a toluidine blue stain at pH 4.0. This method allows differentiation of DNA/protein complexes in in situ and in vitro chromatin. MT chromatin structure in D. saccharalis is variable. Fifth instars have a more...
