Insects are the most abundant and diverse group of animals on earth. Therefore, it is not surprising that they have evolved numerous, generally non-mutually exclusive, adaptations to permit survival at subzero temperatures. In general, these adaptations can be divided into those that prevent freezing of freeze susceptible species (freeze avoidance) and

SEROLOGY OF INSECT PROTEINS: I. PRELIMINARY STUDIES ON THE PROTEINS OF INSECT CUTICLE
Canadian Journal of Zoology, 1962Precipitin tests on extracts of larval cuticle of the housefly (Musca domestica L.) showed the presence of several antigenic protein components, and variations in the protein composition of cuticle during larval development were also demonstrated. One antigenic component from third-instar larval cuticle possessed phenol–oxidase activity.

Publisher Summary This chapter discusses the structure and function of major groups of hemolymph proteins that are common to all insects, storage proteins, lipoproteins, vitellogenins, and inducible antibacterial proteins. It also discusses some proteins and peptides that are present in smaller amounts, sometimes occurring only in a few insect ...

Insects as a Source of Protein
Bulletin of the Entomological Society of America, 1975C. F. Hodge (1911) calculated that a pair of house flies beginning operations in April could produce enough flies, if all survived, to cover the earth 47 feet deep by August. This, of course, is an ecological absurdity but it does convey some idea of the tremendous reproductive potential of some insects.

Nature, 1941
Odier1, Wigglesworth2, Pryor3 and others have demonstrated the presence of protein in the cuticle of various insects. The most modern study is that of Fraenkel and Rudall4 using material from the pre-pupal and pupal stages of the blowfly Sarcophaga falculata. They showed that in the larval stage the cuticle contains a high proportion of a protein which

Diversity and functions of protein glycosylation in insects
Insect Biochemistry and Molecular Biology, 2017The majority of proteins is modified with carbohydrate structures. This modification, called glycosylation, was shown to be crucial for protein folding, stability and subcellular location, as well as protein-protein interactions, recognition and signaling.

Gel filtration of insect haemolymph proteins
Canadian Journal of Zoology, 1968Haemolymph from 6th instar larvae of Malacosoma americanum and 5th instar nymphs of Locusta migratoria was subjected to gel filtration on Sephadex G-200. Three protein fractions were produced in each case. Each fraction was analyzed for protein content and assayed for esterase and tyrosinase activity.

Accumulation of Yolk Proteins in Insect Oocytes
Annual Review of Entomology, 1992In insects, accumulation of yolk, or vitellogenesis, is a heterosynthetic pro cess, in which an extraovarian tissue, the fat body, produces yolk protein precursors ( 1 , 92). Heterosynthetic vitellogenesis occurs even in the most primitive insects, the Apterygota (9, 10, 1 13).

Insect chitinase and chitinase-like proteins
Cellular and Molecular Life Sciences, 2009Insect chitinases belong to family 18 glycosylhydrolases that hydrolyze chitin by an endo-type of cleavage while retaining the anomeric beta-(1-->4) configuration of products. There are multiple genes encoding chitinases and chitinase-like proteins in all insect species studied using bioinformatics searches.
