    Description / Table of Contents: Résumé Les fluctuations du niveau d'acides aminés libres ont été suivies dans des extraits de larves entières du troisième stade d'Anthonomus grandis Boheman (Curculionidae) ayant été piquées une fois par une femelle de l'ectoparasitoïdeBracon mellitor Say (Braconidae). Après la piqûre, le niveau d'acides aminés des larves a d'abord augmenté durant les 6 min suivant l'injection du venin, puis diminué dans les deux heures suivantes. Un second pic d'acides aminés est apparu 4 jours après la piqûre. Les augmentations observées dans le niveau d'acides aminés libres ont toujours été accompagnées par des diminutions synchrones de la quantité totale de protéines solubles. Un possible effet physiologique de l'injection du venin de l'ectoparasitoïde sur la régulation de la nutrition de l'insecte hôte est discuté.
    Notes: Abstract Changes in the free amino acid levels of extracts from body whole homogenates of 3rd instar boll weevilAnthonomus grandis Boheman (Curculionidae) larvae which had been stung once by females of the ectoparasitoidBracon mellitor Say (Braconidae) were determined. Stung larvae exhibited an initial rise in free amino acid levels within 6 min after the venom was injected followed by a decline within 2h. A second free amino acid peak occurred 4 days after initial sting. Observed increases in free amino acid levels were always followed by synchronized decreases in total soluble proteins. The possible nutritional regulatory effect of ectoparasitoid venom on the physiology of the boll weevil is discussed.

    Notes: In this article, we present a study of the localization and properties of the molecular orbitals (MOs) of polyatomic systems by using a comprehensive version of the G1 model. In this version, the wave function is written as a DODS product of univocally determined spin orbitals (MOs), “projected” on the singlet ground state. A procedure for determining the MOs is given and applied to the BeH2 ground state. Equivalent split shell and localized MOs are found. The Be orbitals are seen to exhibit sp hybridization and the localized valence MOs are found to produce - 13.7 kcal/mol localization energy. Multistructural calculations are carried out and show that the present approach is able to describe localized and well-oriented bonds whenever the molecule under study presents only a single well-defined nonresonant chemical structure. © 1996 John Wiley & Sons, Inc.
