Sergey Viktorovich Pushkin
The parent instincts male burying beetles, Nicrophorus spp. are put under doubt when, conspecific females invade on a substratum prepared for oviposition. Though females provide male wit padding possibilities of pairing, they put under threat a survival of the maleâ€™s brood of "parent". To research sexual answer of the parentâ€™s males to females, which invade in their nests, we added the virgina beetles (female) to nest conspecific a steam, which already have initiated to care of descendants. Half of the females (invader) were inseminated by males the parents in trials, with icrophoru investigator (Zetterstedt, 1824). In work the author reduces the experimental data obtained during laboratory learning of genesial cycle and the sexual ratioes for the beetles of a genus icrophorus Kirby N. investigator. Extra-pair copulations for Coleoptera are poorly investigated. In work this act for N. investigator for the first time is featured. In work we shall try to give an explanation to the obtained outcomes.
