Determinação do número de ínstares de insetos utilizando modelo de regressão segmentado Anais da SEB
Ambrosano,Gláucia M.B.; Igue,Toshio; Lourenção,André L..
Data from populations of Anticarsia gemmatalis Hübner larvae, and simulated data considering fixed and variable proportions of larvae head capsules sizes of successive instars, were fit into a segmented polynomial regression. The joint points corresponded to the change of instars and the larvae growing process was represented by a sequence of submodels. This allowed the accurate estimation of the mean size of larvae head capsule, and the confidence interval for each instar.

Determination of larval instars in Chironomus sancticaroli (Diptera: Chironomidae) using novel head capsule structures Rev. Bras. Zool.
Richardi,Vinicius S.; Rebechi,Débora; Aranha,José M. R.; Navarro-Silva,Mário A..
Determining the age composition of a population is important when conducting ecological, taxonomic and environmental assessments. Morphometric measurements of the head capsule, especially the length and width, are widely used in the identification of insect instars, but alternative ways for determining the age of insects can expand the options for the analysis of field and laboratory populations. This study evaluated the morphometry of the antennae, mandibles, mentum and ventromental plates to discriminate among the four larval instars of Chironomus sancticaroli Strixino & Strixino, 1981. The larvae were reared in the laboratory under constant temperature (25°C) and photoperiod of 12/12 hours for 19 days, with a supply of food. Fifteen larvae were...
