Viruses are found in almost all multicellular organisms and chrysomelid beetles are no exception. However, the first virus causing mortality in chrysomelids was not found until 1975 when Ohba found an iridescent virus in Chrysomela vigintipunctata (Scop.).

Zoogeography of the Chrysomelidae

Zootaxa, 2020
The genus Agelopsis Jacoby, 1896 is redefined and revised. Zizonia Chen, 1976 and Liroetinus Lopatin, 2004 are proposed as new synonyms of Agelopsis. Nine species of Agelopsis are recognized: A. aeneoviridis (Lopatin, 2004) (comb. nov.) (China: Sichuan), A. belousovi (Lopatin, 2004) (comb. nov.) (China: Sichuan, Yunnan), A.

Gastral spiculum in Chrysomelidae (Coleoptera)

International Journal of Insect Morphology and Embryology, 1974
Abstract Gastral spiculum is usually a Y- or V-shaped structure formed by a complete or partial modification of the 9th abdominal segment and supporting the genitalia from below. A more or less similarly shaped structure surrounding the base of aedeagus in the Chrysomelidae has also been referred to as gastral spiculum by certain workers, who call ...

Larval gregariousness in the Chrysomelidae

1988
Many species of leaf-feeding insects (for example in various families of Lepidoptera, in tenthredinid Hymenoptera and in chrysomelid beetles) have more or less actively gregarious larvae, the intensity of this phenomenon varying from species to species. In the chrysomelids for example (e.g.

A FEW NOTES ON CHRYSOMELIDAE

The Canadian Entomologist, 1939
The family Chrysomelidae was established by Redtenbacker in 1846, but its principal subdivisions and its definite limits were not fixed until 1848 when that eminent French entomologist, Lacordaire, gave us his “Monographie des Phytophages”.

Mimicry and the Chrysomelidae

1988
The significance of similarities between organisms of the world has long fascinated man — presumably even prehistoric man, later early naturalists, and now experimental biologists, behaviorists, taxonomists, geneticists, etc. How great his preplexity when an observer first realizes that all in nature is not what it appears to be!

Sperm structure and phylogeny of the Chrysomelidae

1988
In recent years it has become clear that there is a close relationship between comparative spermatology and animal taxonomy and phylogeny (Baccetti 1979,1985), particularly in certain groups of insects (Baccetti 1987a, Burrini et al. 1987). The few published descriptions show that there is a peculiar affinity between the Coleoptera Tenebrio (Baccetti ...
