“…The major factor limiting the predatory efficacy of Orius is diapause induction in late autumn and winter in greenhouses lacking supplementary lighting (Yano, 1999). To extend the seasonal limits of biological control, four options are suggested: application of low intensity light in greenhouses to extend the photoperiod and prevent diapause induction (Gilkeson & Hill, 1986; Chambers et al , 1993; Jacobson, 1993); selection for nondiapause strains (Gilkeson & Hill, 1986; Morewood & Gilkeson, 1991); maintenance of high temperature in greenhouses that prevents diapause induction (Morewood & Gilkeson, 1991; Kohno, 1998); and application of nondiapause species or strains from southern temperate or sub‐tropical zones with a low diapause incidence (Gillespie & Quiring, 1993; Hirose et al , 1999). The present results suggest that, when Orius spp.…”

The effects of day-length and temperature on pre-adult growth and induction of reproductive diapause are studied in Orius sauteri and Orius minutus (Heteroptera: Anthocoridae) from northern (43.0°N, 141.4°E) and central (36.1°N, 140.1°E) Japan. In the north, at 20 °C, pre-adult growth is slower under an LD 14 : 10 h photoperiod than under shorter or longer photophases. At 24 and 28 °C, the longer photophases result in shorter pre-adult periods. Acceleration of nymphal growth by short days in autumn appears to be adaptive. In the central region, this response is less pronounced, suggesting that timing of adult emergence is less critical than in the north. Day length also influences the thermal requirements for pre-adult development. The slope of the regression line representing temperature dependence of pre-adult development is significantly smaller and the lower development threshold (LDT) is significantly lower under an LD 12 : 12 h photoperiod than under long-day conditions. The weaker dependence of nymphal growth on temperature and the lower LDT in autumn might be adaptive. In the north, increased temperature shifts the critical day length of diapause induction and suppresses the photoperiodic response in O. sauteri but not in O. minutus . Further south, the incidence of diapause in both species is low even under short-day conditions but the same interspecific difference is observed (i.e. increase of temperature affects the response in O. sauteri but not in O. minutus ). This suggests seasonally earlier diapause induction with weaker temperature dependence in O. minutus than in O. sauteri .

“…We have successfully adopted the first approach, although several authors have also proposed the second. For example, Hirose et al. (1999b) recorded some natural enemies of T. palmi from the subtropical Ryukyu Islands of Japan, suggesting the possible use of, for example, Piocoris varius (Uhler) (Hemiptera: Lygaeidae) and O. strigicollis , in winter greenhouses.…”

Cage trials of an anthocorid predator, Wollastoniella rotunda Yasunaga et Miyamoto, as a biological control agent of Thrips palmi Karny were conducted in Fukuoka, Japan, under winter greenhouse production conditions. Females of W. rotunda were released on caged eggplants, and placed in two greenhouses on 27 October. The development, population growth, and effectiveness of W. rotunda were observed until early March. Results from the cage trials showed that W. rotunda successfully developed, reproduced, and suppressed T. palmi populations under the conditions found in winter greenhouses. During the experiment, one full generation and a second generation of adult predators occurred. The T. palmi population which was exposed to predators remained at a low density throughout the trial period, but it increased dramatically on eggplants without W. rotunda . The maximum difference between predator treatments and controls was approximately 10-fold by the end of January. Wollastoniella rotunda has the potential to be an effective control agent for T. palmi on eggplant, even during the winter in temperate regions.

“…6.3a,b), whereas stipule thrips and lygaeid bugs (Lygaeidae) showed a different visitation pattern. Furthermore, lygaeid bugs typified by big-eyed bugs (Geocoris and Piocoris) are known to prey on thrips (Hirose et al 1999). This observation suggests that stipule thrips and lygaeid bugs do not always depend on the floral resources of S. acuminata.…”
