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

The Number of Naupliar Instars in Cyclopoida (Copepoda)

Crustaceana, 1970
[L'etude detaillee du developpement larvaire de Cyclops scutifer Sars a montre que six stades naupliens sont presents dans les populations naturelles de cette espece. N 4 et N 5 pouvaient etre distingues par la difference de taille et de forme des minuscules epines terminales du corps a un grossissement de 500 environ.

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 ...

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.

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

The Problem of Instar Numbers in Arthropods

2011
The last 20 years the distribution of computing power to individuals through personal computers and the subsequent explosion in the production of scientific software dramatically changed the scientific work. The initial availability of expensive statistical software was replaced by inexpensive commercial packages – i.e., SPSS, SYSTAT, SAS, CART among ...

Biology of the eggs and first-instar larvae

1995
Egg-laying behaviour and selection of oviposition sites, coupled with any subsequent redistribution of egg-masses through drift and active dispersal of first instar larvae, are primarily responsible for determining patterns of larval distribution. It is therefore both logical and convenient that they should be considered in combination.
