We observed instances of cannibalism (intraspecific predation) among intra-instar larvae of Culex pipiens Linnaeus, 1758 while performing a bioassay of Lysinibacillus sphaericus (formerly named Bacillus sphaericus) larvicide, when the larvae were exposed to the larvicide for 48 h in the absence of food. Larvae without symptoms of poisoning attacked and devoured those visibly affected. Cannibalism was more prevalent in 1st-2nd instar larvae than in 3rd-4th instar. This phenomenon should be taken into account when interpreting the results of larvicide bioassays, especially when the exposure lasts over 24 h. The necessity of creating optimal conditions for organisms tested is emphasised., Igor Uspensky and Sergei Braun., and Obsahuje bibliografii
Canningia spinidentis gen. et sp. n. infects the fir bark beetle Pityokteines spinidens Rtt. in Austria. The pathogen attacks mainly the fat body, Malpighian tubules, the muscles and the connective tissue of larvae and adults, and the gonads of adults. The development is haplokaryotic, with single spores. Spores are short tubular, uninucleate, with globular anchoring disc inserted subapically, laterally, in a depression of the endospore wall. Polar filament is isofilar, with 5/6 coils. Polaroplast is composed of two lamellar parts of different density. A new genus Canningia gen. n. is proposed based on differences in ultrastmc-tures of spores from Unikaryon Canning, Barker, Hammond et Nicholas, 1974.
In this article, I explore the relationship between the reproduction of hegemonic discourses of national representation in the reception of literature in translation and processes of canonization. I argue that World Literature as a paradigm hinders our efforts of overcoming the burdens of canonization. As a case study, I analyze the implications of building and reproducing a canon of Japanese literature in translation in the United States for the way Japan has been represented in public discourse in the last thirty years. I will focus on the reception of Murakami Haruki as the contemporary representative of the canon of Japanese literature in translation. My goal is to examine how the circumstances of Japanese literature in translation perpetuate mechanisms of canonization in their engagement and legitimation of an ongoing logic of representation that is non-confrontational with agents in power. I aim to test the extent to which studying the reception of East Asian literature in translation can help us promote a broader discussion on the appropriateness of such frameworks in our understanding of the contemporary literary phenomenon.
A multiplicative functional on a graded connected Hopf algebra is called the character. Every character decomposes uniquely as a product of an even character and an odd character. We apply the character theory of combinatorial Hopf algebras to the Hopf algebra of simple graphs. We derive explicit formulas for the canonical characters on simple graphs in terms of coefficients of the chromatic symmetric function of a graph and of canonical characters on quasi-symmetric functions. These formulas and properties of characters are used to derive some interesting numerical identities relating multinomial and central binomial coefficients.
This paper is a continuation of a previous author’s article; the result is now extended to the case when the lattice under consideration need not have the least element.
