  author={H. Amano and D. A. Chant},
The mating behaviour and reproductive mechanisms for two phytoseiid predators, Phytoseiulus persimilis Athias-Henriot and Amblyseius andersoni (Chant) were observed in the laboratory in Canada. The different mating patterns of the two species appeared to reflect their generic differences. In both species, female fecundity increased with the duration of copulation. Most males of P. persimilis inseminated females with a single endospermatophore transferred to only one of the female spermathecae… Expand
Mating behavior of the predatory mite Kampimodromus aberrans (Acari: Phytoseiidae)
The mating behavior of the predatory mite Kampimodromus aberrans was studied in the laboratory at a constant temperature of 25± 1 °C and a photoperiod of 16:8 (L:D). Forty pairs of newly emergedExpand
Effects of mating factors on reproduction and sex-ratio of the predacious miteamblyseius zaheri yous. & el-bor. (acari, phytoseiidae)
Three factors were examined to determine their effect on the reproduction and sex-ratio in the predacious miteAmblyseius zaheri Yousef & El-Borolossy in the laboratory and all 3 factors studied have no influence on the sex-Ratio of the progeny. Expand
Female mate-receptivity behavior in multiple matings of a predacious mite, Amblyseius womersleyi Schicha (Acari:Phytoseiidae)
It is suggested that acquisition of sperm or seminal fluids is probably a critical factor for mating receptivity and that multiple matings are required in order to reach the full reproductive capacity for A. womersleyi females. Expand
Effect of mating frequency on fecundity and longevity of the predatory mite Kampimodromus aberrans (Acari: Phytoseiidae)
The effect of single versus multiple mating on longevity and fecundity as well as the number of matings required to maximize a female’s reproductive success of the predatory mite KampimodromusExpand
Reproductive compatibility between mite populations previously identified as Euseius concordis (Acari: Phytoseiidae)
The results established that the populations originating from Arroio do Meio, Pontes e Lacerda, Jaguariúna and Viçosa, are reproductively compatible, however, the latter populations and the population from Petrolina are genetically isolated. Expand
Balancing in- and out-breeding by the predatory mite Phytoseiulus persimilis
This study provides a rare example of in- and out-breeding depression in a haplo-diploid arthropod, supporting the optimal outbreeding theory. Expand

Abstract Feeding experiences of predators during immature and adult stages may impact females' reproduction. In the present study, we investigated reproductive performances of Neoseiulus californicusExpand
Mating behaviour of Trichouropoda ovalis (Acari: Mesostigmata: Uropodina: Trematuridae) with notes on phylogeny of reproductive biology in the Parasitiformes
The use of unspecialized chelicerae during spermatophore transfer in Uropodina was confirmed, which suggests that this behaviour is a plesiomorphic character of Parasitiformes. Expand
Adaptive control of copulation duration by males under sperm competition in the mite, Macrocheles muscaedomesticae

  • Experimental & Applied Acarology
  • 2004
Results of the artificial interruption of copulation suggest that males are able to assess the insemination status of their mates and to adjust their copulation duration depending on the probability of fertilizing eggs by their own sperm. Expand
Copulation and egg production in Amblyseius potentillae and Typhlodromus pyri (Acari, Phytoseiidae).
It was shown that in this species one single mating of long duration is sufficient for the total egg production, whereas in T. pyri several copulations are required. Expand
