The haploid genome size (C value) of the northern walkingstick, Diapheromera femorata(Say), was esti- mated to be 1C = 2.55 pg using Feulgen image-analysis densitometry of haemocyte and sperm nuclei. This relatively large genome is similar in size to the genomes of the few other phasmids studied so far, and is consistent with hypoth- eses regarding an upper limit to the size of many insect genomes imposed by the process of metamorphosis, which is relaxed among hemimetabolous orders.

Biology and ecology of the Northern walkingstick, Diapheromera femorata (Say) (Phasmatodea: Diapheromerinae): A review
The northern walkingstick, Diapheromera femorata (Say), is the only stick insect of economic importance native to the United States. Young nymphs feed on various understory shrubs and trees whereas
Genome size variation in lepidopteran insects
The present study represents the first attempt to survey genome size variation in lepidopteran genome sizes, giving estimates for more than 50 species and increasing the coverage of the order to 15 families.
C-value estimates for 31 species of ladybird beetles (Coleoptera: Coccinellidae).
No correlation was found between genome size and body size in the ladybirds, in contrast to some other invertebrate groups but in keeping with findings for other beetle families, however, there is some indication that developmental time and/or feeding ecology is related to genome size in this group.
Phylogenetic distribution of TTAGG telomeric repeats in insects.
The repeated losses of TTAGG in different branches of the insect phylogenetic tree and, in particular, in the most successful lineage of insect evolution, the Endopterygota, suggest a backup mechanism in the genome of insects that enabled them frequent evolutionary changes in telomere composition.
Riboflavin as a Source of Autofluorescence in Eisenia fetida Coelomocytes
The molecular origin of eleocytes autofluorescence was elucidated in coelomocytes expelled via dorsal pores in the integument of Eisenia fetida subjected to electric shock and indicated that riboflavin but not FMN or FAD is the main fluorophore responsible for eleocyte fluorescence in this species.
Characterization of EamaT1, a member of maT family of transposable elements from the earthworm Eisenia andrei (Annelida, Oligochaeta)
A novel transposon named EamaT1 is described from the genome of the earthworm Eisenia andrei, which undergoes an inactivation process as a result of accumulating multiple mutations and is nonfunctional.


Flow-cytometric analyses of intraspecific genome size variations in Bacillus atticus (Insecta, Phasmatodea)
A correlation between genome-size variations and geographic distribution is found and the adaptive nature of genome- size variations in response to environmental changes is discussed, and the class of DNA involved hypothesized.
New DAPI and fish findings on egg maturation processes in related hybridogenetic and parthenogenetic Bacillus hybrids (insecta, phasmatodea)
New investigations on laid eggs and ovariole squashes revealed that in hybridogens the “grandii” set is excluded from the germ line prior to meiosis and that a DNA extra‐synthesis should occur to produce hemiclonal eggs after two cytologically normal meiotic divisions, and brought hybridogenetic oogenesis of Bacillus to be coincident with that of the known heMiclonal organisms.
Genome size and developmental complexity
An appreciation for this rate-complexity interaction has so far been lacking, but is essential for an understanding of the relationships between genome size and development, and may help to explain patterns of variation in taxa as diverse as insects and fish.
From Pixels to Picograms
It is hoped that the accuracy, rapidity, and cost-effectiveness of Feulgen image analysis demonstrated here will stimulate further surveys of genome sizes in a variety of taxa.
Genome size in parental and hybrid species of Bacillus (Insecta, Phasmatodea) from southeastern Sicily: a flow cytometric analysis
These values represent the first flow cytofluorometric data on phasmatodean genome size and appear to be related to abundance and scarcity of C-heterochromatin, respectively.
