“…However, the predatory activity of O. minutus may be limited to short periods in the apple orchards located in northern Japan. The critical photoperiod for diapause induction was estimated to be between 14.5L: 9.5D and 15L: 9D at 22°C in O. minutus (Ito and Nakata, 1998). From the data of daily average temperature and daylength, diapause in O. minutus may be induced from mid-August in Morioka city (39.5°N).…”

“…This is consistent with the Þndings of LeonBeck and Coll (2009) that unmated females of O. laevigatus did not oviposit. Ito and Nakata (1998) also stated that unmated females of Orius sauteri (Poppius) and Orius minutus (L.) failed to lay eggs and that these females showed no ovarian development. In our study, however, ovaries of virgin O. laevigatus females did show some early development.…”

When assessing the reproductive potential of laboratory-reared predatory insects, the role of males is often neglected, although they may have a signiÞcant impact on the reproductive output of their female mates. The current study investigated the effect of age and diet of males on the reproductive capacity of the anthocorid predator Orius laevigatus (Fieber) (Hemiptera: Anthocoridae). The tested diets consisted of eggs of Anagasta kuehniella (Zeller) and an egg yolk-based artiÞcial diet. Regardless of their diet, virgin females did not produce any mature oocytes, indicating that mating is required to complete ovarian development. Food source and age of the males affected the reproductive potential of their female mates. When both males and females were offered the artiÞcial diet, male age had a signiÞcant effect on female oocyte counts. Virgin females that were mated with 0-d-old virgin males produced fewer offspring than those mated with 8-d-old virgin males. In contrast, male age did not affect fecundity when the males were fed A. kuehniella eggs. The implications of the Þndings for the mass production of O. laevigatus are discussed.

“…It has expedited the testing of hypotheses regarding genetic interactions (Shapiro et al 2010) between closely related species such as O. pumilio and O. insidiosus, which reside in closely related ecological niches (Shapiro et al 2009b). As accomplished with other anthocorid species, the limited sympatry of the tropical and subtropical O. pumilio with the ubiquitous O. insidiosus can now be assessed in the context of climatic dynamics, genetics (Hinomoto et al 2004, Honda et al 1998, mating behavior and biology (Horton et al 2005a,b), and diapause and biogeography (Horton et al 1998, Ito and Nakata 1998, Kakimoto et al 2003, Musolin et al 2004, Musolin and Ito 2008.…”

A female minute pirate bug, Orius pumilio (Champion), was found to require both food and mating as an adult to achieve egg development. Last-instar nymphs of O. pumilio were individually placed into 96-well microtiter plates and recovered 24–48 h later as virgin adults, fed only on sucrose or water. The procedure yielded low mortalities. Correct identification of the sex of individuals as last-instar nymphs was achieved with 96% accuracy. The availability of food (eggs of Ephestia kuehniella Zeller) and mates for these isolated females was controlled. Unfed adult females, whether mated or not, did not produce defectible yolk protein when assayed by enzyme-linked immunosorbent assay, nor did they show any follicle development when examined microscopically. Fed but unmated females produced a significant, defectible amount of yolk protein, and some oocyte development was observed, but they contained no fully mature eggs. Females that were both fed and mated fell into two categories: 44% produced mature eggs at a mean rate of 6.4 eggs per female, whereas 56% had ovaries similar to those of fed but unmated females. If treated in mixed sex groups, females that were fed and mated contained more yolk protein than those held in pairs, but increasing the sex ratio of groups above 0.5 (males:females) did not result in a significant increase in yolk protein content. Topical treatment of fed females with methoprene, a juvenile hormone analog, did not trigger an increase in yolk protein contents. We conclude that vitellogenesis is a two-stage process in adult female O. pumilio. Early vitellogenesis requires a nutritious adult diet, whereas full vitellogenesis and egg maturation also require mating.
