Efeitos de um aficida sobre as potencialidades biológicas de dois predadores afidífagos : Cheilomenes sulphurea (Olivier) e Semiadalia undecimnotata Schneider (Coleoptera, Coccinellidae)

open access: yes, 1979
Este trabalho teve como objectivo determinar uma metodologia de avaliação dos efeitos de certos pesticidas específicos utilizados em luta integrada sobre os predadores afidífagos da família Coccinellidae. A escolha dos predadores obedeceu a critérios de evolução morfológica, biológica e ecológica.

Biochemical Changes in Semiadalia undecimnotata (Schneider) Adults during Diapause

Nature, 1965
THE function of food reserves during diapause is often discussed, but there are very few reliable data. The mass hibernation of adult Semiadalia wndecimnotata (Schneider) (Coccinellidae) in accessible places allowed us to make analyses throughout the winter. Both sexes arrive at the winter quarters on warm, windless days from the end of July to the end

Morphology and ultrastructure of integumentary glands of Semiadalia undecimnotata schn. (Coleoptera : Coccinellidae)

Arthropod Structure and Development, 1992
Abstract The ultrastructure of integumentary glands of the adult ladybird, Semiadalia undecimnotata (Coleoptera : Coccinellidae) is described. Two types of glands can be found distributed over the head, thorax, and abdomen: glands without ducts and glands with secretory ducts.

Antennal sensilla and sexual dimorphism of the adult ladybird beetle Semiadalia undecimnotata Schn. (Coleoptera: Coccinellidae)

Arthropod Structure and Development, 1995
The antennal receptors of the adult male and female ladybird beetle, Semiadalia undecimnotata (Coleoptera: Coccinellidae), were examined by scanning and transmission electron microscopy. Twelve types of receptors were characterized and grouped into 5 morphological classes: Bohm, trichoid, coeloconic, basiconic, and chetiform sensilla.

Water budget of Semiadalia undecimnotata schn. larvae feeding onmyzus persicae sulz. studied with HT18O

The International Journal of Applied Radiation and Isotopes, 1980
Abstract In coccinella larvae the total water uptake was determined in two different ways: (1) from the cumulative water diet measured directly, by aphid consumption, and from the vapour cuticular absorption rate, which was estimated with HTO alone in control experiments; (2) from the elimination rate of double-labelled water, HT 18 O, initially ...

Les aptitudes trophiques et reproductrices des femelles deSemiadalia undecimnotata [Col.: Coccinellidae]

Entomophaga, 1984
Les femelles de la coccinelleSemiadalia undecimnotata Schneider ingerent environ 20 mg d'aphides par jour a 22°C lorsqu'il y a surabondance de proies. Dans les premiers jours qui suivent la mue imaginale, ces prises alimentaires provoquent une augmentation sensible du poids corporel des femelles qui par la suite oscille autour d'une valeur moyenne ...
