A “radiosensitivity index” (LTJmean longevity) was correlated with the mean longevity and dry weight of 37 insect species (both sexes of 12 species) representing eight orders. Curvilinear regression analysis reIating radiosensitivity to mean longevity and mean dry weight indicated that 46.3% of the observed variation could be attributed to longevity and 32.6% to the dry weight of the species. I...

This paper presents the first complete and updated list of all 3597 species of beetles (Insecta: Coleoptera) belonging to 92 familiesfound and published in Lithuania until 2011, with comments also provided on the main systematic and nomenclatural changes since the last monographic treatment in two volumes (Pileckis and Monsevičius 1995, 1997). The introductory section provides a general overvie...

In this research we proposed two mathematical models for Isoptera mound growth derived from the Von Bertalanffy growth curve, one appropriated for Nasutitermes coxipoensis, and a more general formulation. The mean height and the mean diameter of ten small colonies were measured each month for twelve months, from April, 1995 to April, 1996. Through these data, the monthly volumes were calculated...

The higher level phylogenetic relationships within the avian feather lice (Insecta: Phthiraptera: Ischnocera) are extremely problematic. Here we investigate the relationships of 1 family (Goniodidae), sometimes recognized as distinct within Ischnocera, using parsimony and likelihood analyses of nuclear and mitochondrial DNA sequences. These data support monophyly for a restricted definition of ...

A rectal valve is known from Bostrichiformia (e.g. Dermestidae, Bostrichidae, Ptinidae), Cucujiformia (e.g. Chrysmeloidea, Cleridae, Curculionoidea, Endomychidae, Tenebrionidae) and Buprestidae, associated with the cryptonephridial system for water recovery from fecal matter. The valve is probably homologous in at least the Bostrichiformia and Cucujiformia although the form it takes may not be....

We present a genome assembly from an individual female Limenitis camilla (the white admiral; Arthropoda; Insecta; Lepidoptera; Nymphalidae). The sequence is 435 megabases in span. Most of the (99.97%) scaffolded into 31 chromosomal pseudomolecules, corresponding to 29 autosomes plus W and Z sex chromosomes. complete mitochondrial was also...

This study presents a revision of the fleas (Siphonaptera) in Chile, gathered from 1993-2013 in response to a request to update our knowledge of the fauna of this country, as catalogued by Beaucournu & Gallardo in 1991 and 1992. For each taxon we give the depository of the type, the main references concerning it, its general distribution, particularly in Chile, and its known hosts, mainly in th...

In Argentina, five genera and 14 species are recorded in the subfamilies Prostemmatinae and Nabinae: Hoplistoscelis sordidus Reuter, Lasiomerus constrictus Champion, Metatropiphorus alvarengai Reuter, Nabis argentinus Meyer-Dür, Nabis (Tropiconabis) capsiformis Germar, Nabis faminei Stål, Nabis paranensis Harris, Nabis punctipennis Blanchard, Nabis roripes Stål, Nabis setricus Harris, Nabis tan...
