Soldier Production Strategy in Lower Termites: From Young Instars or Old Instars? [PDF]

open access: possibleJournal of Theoretical Biology, 2002
We constructed a mathematical model to explain from which instars soldiers should be produced to maximize the growth rate of a termite colony. The model is based on the demography of the lower termite's colony: many of them feed inside the nest. The model predicts the following: (1) When the colony is young (it still has enough food and needs a high ...

Instar Increments in Copepod Growth [PDF]

open access: possibleCanadian Journal of Fisheries and Aquatic Sciences, 1986
There is a difference in the growth patterns of large and small copepods as indicated by lengths at each instar for 55 species of copepods from all latitudes. Large species put on a greater proportion of their adult size relatively late in life compared with small species. This confirms an earlier suggestion based on a comparison of only two species.

Instars in the Carpenterworm, Prionoxystus robiniae1

Annals of the Entomological Society of America, 1973
The number of larval instars of Prionoxystus robiniae (Peck) varied even within broods reared under the same conditions, but it appeared to be influenced by sex and possibly by heredity and temperature. Instar numbers ranged from 8 to 31 and mean head-capsule widths from 0.96 to 6.65 mm.
