Expression of pb-GAL4 in the mouthpart primordia was obscured for a few hours after head eversion by the
histolysis of the salivary glands in the movie using fluorescence optics (Figure 2(J)).

Flight threshold, wing muscle
histolysis, and alary polymorphism: correlated traits for dispersal tendency in the Gerridae.
In contrast to our results, Helff (1926) found that in natural and in artifically induced metamorphosis the rates of
histolysis of the opercular integument are equal on the left and right sides.
The house cricket, Acheta domesticus, loses the ability to fly shortly after adult emergence due to programmed cell death and
histolysis of the flight muscles.
On the basis of previous investigations we selected fecundity and flight muscle
histolysis as additional traits for analysis, the first because it is a primary factor in the trade-off (Roff 1984, 1994b) and the second because it likely plays a role in the trade-off by shunting resources from the muscles to egg production (Zeta and Denno 1997).
Some evidence also suggests that they can induce tissue
histolysis during inflammatory reactions (Jullien, 1927; Jacquemain et al., 1947; Cowden and Curtis, 1981; Feral, 1988).
Flight muscle
histolysis in the house cricket, Acheta domesticus, is induced by juvenile hormone (JH) and is an example of active programmed cell death that requires de novo protein synthesis.
Wing morphs may differ in mating propensity early in the season, prior to flight muscle
histolysis, but should not differ thereafter.
In the house cricket Acheta domesticus, flight muscle
histolysis is induced by juvenile hormone (JH) and is and example of active programmed cell death.
Metamorphic stages were scored according to the following criteria, documented previously in Santagata (2002): stage one--partial
histolysis of hood, telotrochal cells, and the larval portion of the tentacles; stage two--complete
histolysis of larval tissues and partial eversion of the juvenile trunk sac; stage three--larval gut pulled inside the juvenile trunk sac, but portions of the larval trunk epithelium not completely pulled into the juvenile body; stage four--all previous events plus the larval trunk epithelium completely pulled into the juvenile body.
The repair phase, which includes the overall 48-h post-autotomy period, comprises wound closure and
histolysis of the damaged tissues.
