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

Journal 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 ...

Changes in Haemolymph Proteins in First Instar Locusts

Archives Internationales de Physiologie et de Biochimie, 1966
A number of studies have recently shown that the hacmolymph proteins of Insects change during development. Most of the work in this field has however been done on holometabolous Insects, while only a few studies have been made on the Hemimetabola (STEINHAUER and STEPHEN, 1959 on Periplanefa ; MISSELIJN, KARCHER, DE KEYSER, and VAN SANDE, 1959 on ...

Feeding Ability of Micronecta grisea Nymphal Instars and Adults on Third Instar Aedes aegypti Larvae

Tropical Natural History, 2009
Pygmy waterboatmen, Micronecta grisea, were collected and used to establish laboratory cultures in order to study the predation rates and feeding behavior of nymphal instars (N) and adults upon third instar larvae (L3) of Aedes aegypti to assess their potential for biological control. The body length, head capsule size and head length of 330 nymphs and

Instar Increments in Copepod Growth

Canadian 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.
