“…Both forms are distributed widely in China; the green form was named T. urticae, and the red form was named T. cinnabarinus (Boisduval) (Xie et al 2006;Sun et al 2012). The Kanzawai spider-mite, T. kanzawai Kishida is also red in color and similar to the red form of T. urticae in morphology and biology (Oku 2008;de Mendonca et al 2011;Chen et al 2014).…”

Tetranychus urticae Koch and Tetranychus kanzawai Kishida are important pest mites of various crops of economic importance around the world. Prey consumption and functional responses of two species of phytoseiid mites on these two spider mites were evaluated at 25 ± 1°C, 65 ± 10% RH in the artificial climatic chamber with a photoperiod of 16 h light:8 h dark. The functional response of both Neoseiulus species was type II on three immature stages (egg, larva and protonymph) of Tetranychus species. The value of attack rate coefficients (α) of N. californicus to each stage of Tetranychus was greater than N. longispinosus, and the shortest handling time (T h ) was obtained on larvae followed by nymphs and eggs. The maximum attack rate (T/T h ) on eggs, larvae and nymphs of T. urticae was estimated to be 11. 87, 37.23 and 26.95 for N. californicus, and 18.43, 28.98 and 20.67 for N. longispinosus; the maximum attack rate (T/T h ) on eggs, larvae and nymphs of T. kanzawai was estimated to be 11.90, 42.97 and 39.60 for N. californicus, and 24.15, 31.60 and 24.45 for N. longispinosus. When different densities of prey were offered to the predators, more prey was consumed at higher prey densities, and interaction between prey stage and prey density was significant for N. californicus, but not significant for N. longispinosus. The ability of N. californicus preying on larvae and nymphs of both Tetranychus species was significantly greater than N. longispinosus at high prey densities, but N. longispinosus consumed more eggs than N. californicus.

“…Moreover, the effectiveness of mating may also rely on the interval between the first and the second insemination. In Tetranychus urticae (Helle 1967) or T. kanzawai (Oku 2008), for example, the first copulation is effective. First male sperm precedence appears to be adaptive in this case, since, similarly to A. allotrichus , tetranychid males spend time and energy on the prolonged guarding of pre-emergent females.…”

Repeated visitations of spermatophores and polyandry in females of eriophyoid mites

Eriophyoid females store sperm either asymmetrically in one spermatheca, or symmetrically in both spermathecae. Previous studies have suggested that species in which females store sperm asymmetrically pick up sperm from only one spermatophore, while those with symmetrical sperm storage pick up sperm from two or more spermatophores during their lifetime. The aim of this study was to examine spermatophore visitation behaviour and symmetry of sperm storage in Aculops allotrichus from the black locust tree and Cecidophyopsis hendersoni from the yucca. This would indicate monandry or polyandry in these species. In both eriophyoids, the spermatophore visitation consisted of three phases: mounting, lying on the spermatophore and dismounting. Aculops allotrichus stored sperm asymmetrically. However, nearly one-third of the observed females visited two spermatophores, rather than only one in their lives. When A. allotrichus females visited two spermatophores they spent a similar amount of time at the first and at the second visitation. Also, the times of visitation of the first of the two spermatophores and the single spermatophore in a female lifetime did not differ significantly. This would suggest that apart from monandry, double insemination also occurs in this species. By contrast, C. hendersoni females were polyandrous. They stored sperm symmetrically and visited several spermatophores, on average 1.54 (max 6) per day, and up to 33 spermatophores in their lives. The benefits of repeated spermatophore visitation and the possible mechanisms of sperm storage in both species are discussed.

“…Males are also aggressive towards conspecific males, and they even kill males inside nests (Saito 1990 ). One explanation for this male–male aggression may be that it is relatively more effective to acquire immature females and mate with them just after they moult to adulthood rather than to look for other adult females available, because females primarily utilize sperm from the first mating and the second mating is not effective in spider mites (Boudreaux 1963 ; Helle 1967 ; Oku 2008 ). The degree of male–male aggression varies among populations in the mainland of Japan (Saito 1995 ): the males are highly aggressive in some populations (hereafter called HG = high in male aggression) and males show very little aggression in other populations (hereafter called LW = low in male aggression; Saito and Sahara 1999 ; Sato et al 2013a ).…”

Incomplete premating and postmating reproductive barriers between two parapatric populations of a social spider mite

et al. 2015

Closely related species with overlapping distributions often show premating reproductive barriers to avoid hybridization. Stigmaeopsis miscanthi (Saito) is a social spider mite infesting Chinese silver grass, and the species consists of two parapatric groups with frequent contacts within the contact zone. They differ in male–male aggressiveness, male morphology, female diapause traits, and life history parameters. There is incomplete but strong post-mating reproductive isolation between the two groups, and their DNA sequences are slightly different, suggesting that they diverged recently. In this study, we investigated premating reproductive barriers. We found that females from different groups frequently shared nest webs, indicating no barriers in the phase of nest establishment. However, inside nests, males from either group showed less courtship behaviour to females of the other group and they copulated less frequently with them when compared to females of the same group. However, the premating reproductive barrier was incomplete and asymmetric. Females of one group frequently resisted courtship by males from the other group, but females of the other group did not. We conclude that some gene flow may occur in the contact zone between the two groups.
