However, the increase in frequency of heterochromatin decondensation in Malpighian tubules of the infected specimens subjected to heat shock may be in agreement with this hypothesis.
With regard to the analysis of the nuclear phenotypes in the Malpighian tubules of infected P.
The genital arch area and malpighian tubules area data showed significant deviations from normality (W = 0.93, P = 0.0005 and W = 0.92, P = 0.0142, respectively).

The" posterior midgut," defined as the region studded irregularly with the appendices (elaborated on later), is followed by a smooth "post posterior midgut." The undifferentiated hindgut starts within the 4th or 5th abdominal segment, marked by the origin of the Malpighian tubules. These number in the dozens in all species, with excretory and calciferous tubules as described in Savage (1962).
In all cases the appendix tubules are one-third the diameter of the Malpighian tubules and motile: in Euphasmatodea they are coiled like springs, and contract and expand throughout the body cavity (Shelomi & Kimsey 2014).
BdTre2 was detectable in the midgut, Malpighian tubules, and fat body.
Trehalase2 activity found in the midgut, Malpighian tubules and fat body was 0.28, 0.34 and 0.25 [micro]mol [mg.sup.-1] protein [min.sup.-1], respectively.
Our results are in accord with the localization of V-ATPase in the apical region of MR cells in a variety of animals--for example, in pavement cells in the gills of freshwater fish (Lin et al., 1994; Sullivan et al., 1995); in distal duct cells of the cockroach salivary glands (Just and Walz, 1994); in the midgut, Malpighian tubules, and silk glands of lepidopterans (Schweikel et al., 1989; Pietrantonio and Gill, 1995; Azuma and Ohta, 1998); and in the MR cells of the toad urinary bladder (Brown et al., 1988).
(1998) found a higher activity of 192.3 pmol Pi/([mu]g protein [cdotp] min) in a 600 X g supernatnat obtained from the homogenates of Malpighian tubules in Locusta, and Sallman et al.
The passage of the midgut to the hindgut is characterized by the insertion of Malpighian tubules
. In the hindgut, the ileum is an elongated tube with constant diam, followed by a larger tubular rectum (Fig.
popilliae infections were diagnosed by removing a small portion of Malpighian tubule
from each beetle and examining them microscopically for sporophorous vesicles (Andreadis & Hanula 1987).
