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 ...

Instar and outstar learning with memristive nanodevices

Nanotechnology, 2010
The instar and outstar synaptic models are among the oldest and most useful in the field of neural networks. In this paper we show how to approximate the behavior of instar and outstar synapses in neuromorphic electronic systems using memristive nanodevices and spiking neurons. Memristive nanodevices are especially attractive for this application since

Intraspecific Variability in Number of Larval Instars in Insects

Journal of Economic Entomology, 2007
The number of larval instars varies widely across insect species. Although instar number is frequently considered to be invariable within species, intraspecific variability in the number of instars is not an exceptional phenomenon. However, the knowledge has remained fragmentary, and there are no recent attempts to synthesize the results of relevant ...

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.

Cannibalism and early instar survival in a larval damselfly

Oecologia, 1994
Cannibalism by larval damselflies late in larval development on larvae a few instars smaller has been widely documented. I examine here the survival of eggs oviposited near the end of the flight season of adult Enallagma boreale in the presence and absence of potential cannibals, individuals that hatched from eggs earlier in the season, over an ...

Nymph Anatomy and Instar Determination

2019
Knowledge of the external anatomy of Odonata nymphs is necessary for learning how to use the keys for identification. Basic morphology and terminology of all structures crucial for identification of Anisoptera nymphs to family, genus and species are described and illustrated in detail beginning with orientation of the dragonfly nymph body and the basic

INSTAR DIFFERENTIATION IN LARVAL CHIRONOMIDAE (DIPTERA)

The Canadian Entomologist, 1974
AbstractExamination of the most commonly used criteria for separating instars in larval chironomids, based on a study of 29 species from three subfamilies in Marion Lake, British Columbia, revealed that only head capsule width or length is suitable. Most chironomids appear to have four larval instars.
