The first instar larva moults and the second instar larva continues moving within the host-plant stem. In 1997 and 1998, 6 and 12 newly moulted fourth instar larvae respectively were ascribed to a specific temperature and type of leaf. The newly moulted individuals were recognized by their size and the presence of exuviae. To determine the actual fertility, for several seasons newly moulted males and females were kept until their death in outside wire cages. The second stadium lasted for 2-3 days, after which they moulted (9 days post-oviposition). The larvae in the fish moulted to fourth-stage larvae. On primary exposure they observed an inflammatory reaction provoked by developing larvae, their excretory/secretory products and sheaths left behind after moulting. Feeding was suspended when larvae showed moulting behaviour. Variations in extent of lectin binding within populations may be related to moulting. Larval performance was studied by following larvae enclosed in cages from newly moulted second instars to third instars in the field. The parasitoid larva stays at its second instar until the host reaches its final instar, and just then moults to its final instar. Every individual larva that survived to the end of the experiment had moulted to the third instar. A few begin to display some slight irregularity in growth, but the great majority moulted within seven to eight days, averaging seven days. The adult stage is reached on the 11th day after three moults occurring about every fourth day. The second instar larvae exposed to young plants had moulted to third instar by t3 (table 2). Evidently nematodes from challenge transmissions failed to remain anchored in the stomach wall during their critical maturation moults and were ultimately passed with host faeces. The presence of collagen on the surface of the cuticle of moulting stages of plant parasitic nematodes has been observed for the first time. Immediately after moulting the colours are pale, but in two or three days the shades described below develop. The process is then repeated as the nymph moults into an adult. Of the two eggs obtained, only one hatched; the larva fed externally on its host and moulted once before dying. However, moulting into adult before exposure did not affect ingestion of coracidia. A larva hatches out of each egg, and moults into a protonymph after only 2 days. After hatching from the egg, the development of the 1st-stage to the 3rd-stage larvae involves 2 moults. There is some uncertainty regarding the number of moults performed in the egg. The larvae stayed in the skin for 48 h before emigrating to the lungs and moulting to the 4th stage on days 6-8. As with the depth of pupation, the depth at which larval moults occur may depend on soil texture, compaction and soil moisture. They moulted within six to seven days, averaging six days. At the start of each recording day third instars of uniform size that had just moulted (within l h) were selected for use. Shortly after the adult moults she releases ova into her ovaries. After eggs had been deposited, successive moults produced the infective larvae, following a specified delay. During migration, several moults occur and instars encounter a variety of tissue barriers and environmental cues. Non-parametric tests were used to compare scutum lengths of ticks moulted in the laboratory with those of feeding adult female ticks collected from sheep. There is no evidence that the parasite moults in the macroinvertebrate host. By the 25th day, when an infected plant was harvested in order to monitor the nematode's growth rate, 72 % of these nematodes had moulted. In many species, the ovarian ecdysteroids occur primarily as polar conjugates and are largely passed into the eggs, where they may be involved in embryonic moults. Certainly the epidermis of the body wall must become more and more involved in moulting and in the formation of the new cuticle as development proceeds. None of the larvae moulted. Interruptions of feeding in concurrence with moulting periods never lasted more than 24 h, as larvae were well synchronized and feeding was resumed when 80% of moulting larvae had ecdysed. Most larvae at site 1 moulted at depths of 150-300 mm (4/5), while most larvae at site 3 (4/5) moulted at depths of 300-500 mm. Furthermore, fifth instar larvae were transferred between the two temperatures at the early (within one day after moulting) and middle (end of feeding, about 5 days after moulting) fifth instar. The head capsule which detached from the newly moulted larva was collected and kept in a specimen vial filled with 70% alcohol to determine the number of instar. Immunolocalization studies in planta and in juveniles inside eggs were performed to assess whether this protein is expressed on the surface of the cuticle of moulting nematodes. Mortality of the parasites by day 17 for all cell lines varied between 19-6 and 40-5% and moulting rate between 10 and 41-6%. Actually, however, the mortality was very high amongst nymphs fed on either very small or nearly fullgrown bolls, whilst on half-grown bolls the majority of the second instar nymphs moulted. There was a progressive decrease in mortality, and in length of stadium of those which moulted, nymphs fed on a series of bolls of increasing size. No appreciable mortality occurred in the highly or lowly infected ticks exposed to field conditions until about 33 weeks after moulting of the ticks when it increased rapidly. However, it is an extravagance, and unhelpful to the poultry industry, when moulting is induced to produce more eggs. From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 Moulting is induced to obtain a flow of eggs to the market throughout the year, because otherwise the supply of eggs would fluctuate.

Contains Parliamentary information licensed under the Open Parliament Licence v3.0 Is it not a fact that the average hen moults for only about six weeks a year, and that these stringent rations have already been in force for several months?

Contains Parliamentary information licensed under the Open Parliament Licence v3.0 After moulting, the birds become gradually duller and the dark markings fainter as the plumage becomes more worn.

In order to do this, these developmental sequences have been photographed at regular intervals and followed through to the final moult in single living specimens. Living male specimen that has completed its final moult. After moulting, the young terns resemble the adult, but still have a variegated wing pattern with a dark bar on the inner flight feathers.

The changes in the structures following each moult are figured (fig. 2). The empty egg-shell may remain attached to the posterior segments of the larva until the first moult occurs ; more usually it is shed. When hosts were parasitized as fourth or fifth instars, they did not always moult again before the parasitoid was ready to exit. Direct developing individuals are always produced parthenogenetically, one brood during each adult moult. The name is misleading, since the shell is only soft immediately after moulting, and is usually hard. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license.

After completing initial development, the eggs are deposited in the brood chamber on the back of the adult following her next moult.

Seabirds and seals import large quantities of nutrients from the ocean when they breed and moult on the island. Mites that were unable to feed in the experimental system died, while the adapted animals continued to feed, moult and reproduce. Since copepods cease growing when they become adult, the need for compensatory growth disappears after their final moult. During this period the larvae did not moult. Rejected larvae can neither install themselves in the intestine nor moult. Juveniles have broader buff feather edges, and tend to have looser, scruffier plumage, like moulting adults.

Since a moult could not be observed between the larval and prepupal stages, the latter could simply represent an early stage of pupal formation.
