Investigations into the bioactivity of the hexane, ethyl acetate, chloroform and methanolic fractions drawn from a variety of plant extracts have revealed that caterpillars raised on an artificial diet treated with different extracts register a decrease in the pupal weight, larval size, feed conversion efficiency, embryonic development, morphometric alterations in the adults, defective pupae, differences in the pupal sizes obtained, larval mortality, flawed adults with retention of the frontal carapace, deformed wings, inhibited growth and incomplete ecdysis (Matos et al., 2006; Cunha et al., 2008; Ribeiro et al., 2015).
Finally on 2 September 2013, we tracked a telemetered adult male undergoing ecdysis to Shed Rock 5, and we also found another group of 5 shed skins near the edge of the wetland (Shed Rock 7) approximately 40 m southeast of Shed Rock 6.
Histological and ultrastructural studies of Beauveria bassiana infection in Leptinotarsa decemlineata larvae during ecdysis. J.
Developmentally and physiologically distinct phases were examined by dissecting ovarioles from pharate adults 6 d and 10 d after larval-pupal ecdysis in phosphate-buffered saline (PBS; 0.15 mol [1.sup.-1] NaCl, 10 mmol [1.sup.-1] sodium phosphate buffer, pH 7.4).
The increase in the concentrations of the biochemical constituents of the hemolymph, particularly carbohydrates and lipids observed at during the pre- ecdysis period, could be explained by the digestion of the old cuticle releasing proteins and carbohydrate in the hemolymph, and an inhibition of secretion of the new cuticle following diflubenzuron treatment [27].
As in all crustaceans, ostracods grow in discontinuous stages called instars through the process of ecdysis. When the body of an instar has grown too large for its exoskeleton, the rigid chitinous and calcareous valves are moulted.
azedarach, such as repellence, antifeedant effects, developmental delay and halting of ecdysis, reduction of fertility and fecundity, behavioral and physiological changes leading to possible mortality (Defago et al., 2006; Nathan, 2006; Bullangpoti et al., 2012).
The insects were maintained as previously described in a dark incubator with a 12:12 h light/dark photoperiod and were checked daily for ecdysis or death.
Several additional factors have been proposed to be involved in the regulation of JH biosynthesis by the CA, including biogenic amines, 20hydroxyecdysone (20E), ecdysis triggering hormone (ETH), and short neuropeptide F (sNPF) [2].
A specimen having different article numbers in the left and right uropod could thus reflect an incomplete ecdysis. However, the males of Leptochelia are terminal, and therefore do not increase in size or go through ecdysis.
Both extrinsic and intrinsic factors trigger the ecdysis, mating and gonadal development (Sastry 1983) in order to overlap periods of high habitat quality for larval development (Boolootian et al.
Crustacean hyperglycemic hormones (CHHs) are mainly detected in the X-organ sinus gland complex, which is situated in the eyestalks of crustacean 32] and considered to be playing important roles in multiple physiological effects, such as carbohydrate metabolism [33], reproduction [34], osmoregulation [35], and ecdysis [36].
This pink coloration appears to develop for a few days before and after ecdysis (J.C.
Para implementar el encaminador NAT64, se utilizo un desarrollo de la firma Viagenie denominado "Ecdysis: open- source implementation of a NAT64 gateway", el cual permite habilitar una estacion para que realice las funciones de este encaminador.
