Data on the distribution of Callipogon relictus Semenov, 1899 over the Russian Far East were generalized. The distribution map for C. relictusis based upon long-term observations and collection...

The developmental biology of the relict longhorn beetle Callipogon relictus Semenov, 1899 was studied from egg to adult in the laboratory for the first time. The molting dynamics and morphometric characteristics of all the larval instars were determined. The location of larvae within the tree trunk was investigated by nondestructive modern methods. The reproductive behavior and the process of oviposition are described. Individual development of the species under laboratory conditions, at constant temperature and humidity, took 44 months, suggesting that in the nature it extends over at least four years.

A review of Bolboceratidae species from the Russian Far East is given. The distribution of the species is considered. Maps of their ranges in the territory of Russia are compiled. Bolbotrypes davidis (Fairmaire, 1891) was found in the Jewish Autonomous Area for the first time. Micetophagy of Bolbocerodema zonatum Nikolajev, 1973 and coprophagy of Bolbotrypes davidis are confirmed. The phenology of their adults and topical preferences are considered. The whole available information on the little-known Bolbelasmus orientalis Petrovitz, 1968 (holotype, the type locality, citing) is provided.

Two species of dodder are widespread in the Russian Far East—alien species Cuscuta campestris Yunck and native C. japonica Choisy (Cuscutaceae Dum.). For the first time we have identified individual species of Smicronyx genus in relation to specific dodder species as there was no such a research done in the Far East before. Smicronyx rubricatus Kono, 1930 was found on Cuscuta japonica Choisy, but plant galls were not detected. The insects fed on dodder sap and mate during the flower bud formation and flowering stages. Smicronyx madaranus Kono, 1930 was found to affect Cuscuta campestris Yunck.; its larvae form stem galls.
