  • observations sur Nabis pseudoferus pseudoferus remane et Nabis occidentalis rieger comparaison avec Nabis punctatus costa rhynchota nabidae
    Bulletin de la Société entomologique de France, 1999
    Co-Authors: Elisabetta Chiappini, Maria Cristina Reguzzi
    Abstract:

    Les auteurs font la description morphologique des adultes et des larves des especes Nabis pseudoferus pseudoferus Remane et N. occidentalis Rieger, avec les observations sur la biologie et la distribution des especes. Une comparaison est faite entre les stades preimaginaux des deux especes considerees et ceux de N. punctatus Costa.

  • egg structures of four Nabis species rhynchota nabidae
    International Journal of Insect Morphology & Embryology, 1998
    Co-Authors: Elisabetta Chiappini, Maria Cristina Reguzzi
    Abstract:

    Abstract Despite the numerous works on insect egg structure, detailed studies on Nabis genus (Rhynchota : Nabidae) have not been carried out previously. The external morphology and internal chorionic structure of the eggs of Nabis pseudoferus pseudoferus Remane, Nabis occidentalis Rieger, Nabis punctatus Costa and Nabis rugosus L. were investigated, using scanning electron microscopy, to improve our knowledge of their organization. To assess their role in taxonomy, a comparison between the eggs of the 4 species under consideration was carried out. The eggs are jar-shaped with the front end narrowed in a “collar” and closed by an operculum. The chorion, except in the regions of the collar and the operculum, is organized in an outer layer of about 4–5 μm, separated from the inner surface by a “pillars” layer of about 0.5–1 μm. In the region of the collar, the chorion has small internal channels which represent the aeropyles; their number varies very considerably even within the same species. The operculum is made up of closed spaces filled with air in communication with the aeropyles and the “pillars” layer, thus forming a single space that represents the respiratory system. The general shape and characteristics of the eggs of N. pseudoferus, N. occidentalis and N. rugosus are very similar; only N. punctatus can be identified with certainty at the egg stage.

  • efecto de carbaril metamidofos lambda cihalotrin y spinosad sobre ninfas de Nabis punctipennis blanchard hemiptera nabidae
    Boletín de sanidad vegetal. Plagas, 2009
    Co-Authors: C Romero, Jaime E Araya, M A Guerrero, Tomislav Curkovic
    Abstract:

    ROMERO, C., J. E. ARAYA, M. A. GUERRERO, T. CURKOVIC. 2009. Effects of carbaril, metamidofos, lambda cyhalothrin and spinosad on nymph of Nabis punctipennis Blanchard (Hemiptera: Nabidae), Bol. San. Veg. Plagas, 35: 371-376. Adults of Nabis punctipennis Blanchard were collected in alfalfa to set laboratory rearings and obtain nymphs for toxicology studies. The aphid Acyrthosiphon pisum Harris was used as prey. The effect of concentrations equivalent to 50% of the average of the range recommended commercially for spinosad (6.86 g i.a. hl-1), carbaryl (106.25 g i.a. hl-1), metamidophos (57.90 g i.a. hl-1), and lambda cyhalothrin (625 mg i.a. hl-1) were determined onto stage IV-V nymphs. At the concentrations applied, metamidophos was the most toxic insecticide and had no nymph surviving after day 6th; lambda cyhalothrin and carbaryl were moderately toxic to nymphs in comparison with the control; spinosad did not have significant differences with the control.

  • biologia del depredador generalista Nabis punctipennis blanchard hemiptera nabidae
    Phytoma España: La revista profesional de sanidad vegetal, 2007
    Co-Authors: Carlos Romero Salvador, Jaime E Araya, M A Guerrero, Tomislav Curkovic, Elisa Vinuela Sandoval
    Abstract:

    Se ha estudiado en laboratorio la morfologia (se incluyen macrofotografias), duracion de los estadios ninfales, oviposicion y alimentacion del chinche depredador Nabis punctipennis Blanchard (Heteroptera: Nabidae) recogido en alfalfa en la Region Metropolitana de Santiago de Chile, sobre el pulgon del guisante Acyrthosiphon pisum (Harris) (Hemiptera: Aphididae). Cada hembra inserto un promedio de 200 huevos, alineados en grupos de 9 a 12, en la parte inferior de los tallos mas tiernos de plantas de haba (Vicia faba L.). Durante su desarrollo, la especie pasa por cinco estadios ninfales, con una duracion media de 3,4- 4,8- 5,5- 12,0 y 4,2 dias respectivamente, cuando se mantenian a 26,5oC, 45% HR y 16:8 (L:O). Bajo estas condiciones, el periodo desde la eclosion del huevo hasta la emergencia del estado adulto tarda 29,9 dias. No se detecto canibalismo en ninfas de tercer a quinto estadio, pero se observaron ninfas de primer estadio depredando otras ninfas neonatas.
