Interspecific interference in the closely related predatory mites <i>Neoseiulus womersleyi</i> and <i>Neoseiulus longispinosus</i> (Acari: Phytoseiidae)

Description
ABSTRACTReproductive interference is known to occur in the morphologically similar species Neoseiulus womersleyi and Neoseiulus longispinosus: crosses between N. longispinosus females and N. womersleyi males produce (a few) female offspring, reciprocal crosses produce only male offspring. Details of the interspecific reproduction process remain largely unknown. In this article, we investigated intraspecific and interspecific crosses, spermathecal vesicles and spermatophores in females, and molecular identification of F1 hybrids based on the internal transcribed spacer (ITS) region of nuclear ribosomal RNA (rRNA). The copulation times of interspecific crosses were similar to those of intraspecific crosses, yet interspecific crosses between N. womersleyi females and N. longispinosus males exhibited extremely low fecundity with no female offspring. On the other hand, 1 out of 35 reciprocal crosses produced viable, but sterile female offspring (F1). Intraspecific crosses of N. womersleyi and N. longispinosus ...
