    Notes: [Auszug] Highnam5 reported that the neurosecretory cells of a sphingid moth contained no secretory granules early in the pupal diapause period. During three weeks of exposure to low temperature, the cells began to secrete granules that passed down the axons into the corpora cardiaca. After three weeks of ...

    Impairment of reproduction of the cigarette beetle, Lasioderma serricorne (Coleoptera: Anobiidae) with the insect growth regulator, methoprene (1977)
    Springer

    Description / Table of Contents: Résumé L'exposition de la femelle adulte de Lasioderma serricorne au contact d'un papier filtre traité avec du méthoprène, régulateur de croissance des insectes, a entraîné une réduction significative de la reproduction, en fonction de la dose. Ni le comportement, ni la fécondité ne furent affectés. La fertilité des œufs n'a pas été touchée chez les femelles non traitées qui s'accouplèrent avec des mâles ayant été exposés au méthoprène. L'efficacité du contact avec le méthoprène, en empêchant la reproduction des femelles de L. serricorne, aussi bien chez les femelles accouplées que chez les femelles vierges, et l'effet prolongé du méthoprène, permettent de considérer favorablement son usage pour le contrôle de cette espèce. Son emploi le plus efficace devrait concerner la protection des produits conditionnés en emballages.
    Notes: Abstract Exposure of sexually mature female Lasioderma serricorne (F.) to filter paper treated with the insect growth regulator (IGR), methoprene, resulted in a dose-dependent decrease in reproduction. Female reproductive behavior and fecundity were not affected. The lethal effect was manifested during late embryogenesis. Egg fertility was not influenced among untreated females that mated with males that had been exposed to the IGR. The effectiveness of this treatment suggests that methoprene may be useful in controlling the cigarette beetle on packaged commodities.

    Diapause induction in Ephestia cautella: An interaction between genotype and crowding (1980)

    Description / Table of Contents: Resume L'induction de la diapause larvaire d'Ephestia cautella (Walker) dépend du génotype et de la densité larvaire. Des croisements à l'intérieur de la souche diapausante donnent 79% de diapause aux fortes densités larvaires et 40% aux faibles densités. Les croisements des adultes de cette souche avec ceux de la souche non-diapausante donnent 36% de diapause aux fortes densités et 6% aux faibles densités. La fréquence de fin de diapause est héréditaire et dépend de la température. Ces résultats peuvent expliquer les variations saisonnières du taux de diapause E. cautella dans la pulpe de citron stockée. La diapause larvaire a été induite chez des groupes de chenilles par surpeuplement dans des élevages standards, et chez des chenilles isolées par élevage sur une quantité limitée d'aliments frais ou sur une quantité abondante d'aliments frais contenant des résidus alimentaires provenent d'élevages surpeuplés. Les effets inducteurs de ces résidus alimentaires disparaissent après extraction avec les solvants de lipides. Une certaine action est observée par de l'extraint sec sur de l'aliment frais.
    Notes: Abstract Larval diapause induction in Ephestia cautella (Walker) (Lepidoptera: Pyralidae) is a function of the interaction between genotype and larval crowding. A diapause stock in which 79% of the larvae diapaused under crowded conditions and 40% diapaused under uncrowded conditions was maintained by selection. Outbreeding of adults from this diapause stock to those from a non-diapause stock resulted in 36% diapause under crowded conditions and 6% diapause under uncrowded conditions. The rate of termination of larval diapause is inheritable and temperature dependent. These data seem to explain the seasonal trends in percentage larval diapause among E. cautella infesting citrus pulp during storage. Larval diapause was induced in groups of larvae by crowding in mass cultures and in single larvae by rearing on a small amount of fresh diet or on a larger amount of fresh diet containing residual diet from crowded cultures. The diapause-inducing effects of this residual diet could be removed by extraction with lipid solvents. Some activity was demonstrated when the extract was dried onto fresh diet.

    Non-steroidal ecdysteroid agonists: Tools for the study of hormonal action (1995)

    Notes: The first non-steroidal ecdysteroid agonists are dibenzoyl hydrazines and are typified by the compounds designated RH-5849 and RH-5992. The discovery that these compounds mimic 20E in a variety of insect orders, and especially the Lepidoptera, generated great interest from the research and agricultural communities. Such compounds provide important new research tools for physiological, biochemical, and molecular studies. In addition, the potential for application to agricultural pests looks very promising, especially for RH-5992 (tebufenozide). This review evaluates the evidence on the specificity of the ecdysteroid-like actions of these materials and considers their application for research and pest management. © 1995 Wiley-Liss, Inc.This article is a US Government work and, as such, is in the public domain in the United States of Amerira.
