“…All over the world markets globalization and increased traveling of people are allowing for increasing numbers of invasive species to be brought into countries (Perrings et al 2000 ;Clercq et al 2011 ). Suitable reactions to these pests are needed and development and implementation planning should be arranged.…”

Insect pests and disease infestations are the primary constraints in rice (Oryza sativa) production systems. The rice stem borer and brown plant hopper have the largest share. Concerns about the sustainability of conventional agriculture have prompted widespread introduction of integrated pest management, an ecologicallybased approach to control of harmful insects and pests. Integrated pest management is intended to reduce ecological and health damage from chemical pesticides by using natural parasites and predators to control pest populations. The main points of this review are: (1) integrated pest management (IPM) practices in rice have been developed in different ways in many countries of the world, but these practices vary with the socioeconomic and environmental characteristics of each country.

“…Not only can polyphagous natural enemies sustain themselves on non-target foods when the target prey is absent in the agricultural ecosystem, their generalist feeding habit can also be an asset increasing their market value as a management tool against different pest species (De Clercq 2002; Berkvens et al 2009). Polyphagy of a non-native biological control agent can, however, also be disadvantageous when it spreads to natural ecosystems after being released and affects the abundance of non-target species, thus threatening local biodiversity (van Lenteren et al 2003;Loomans and van Lenteren 2005;De Clercq et al 2011). For this reason, the release of polyphagous biological control agents is not always considered to be environmentally safe and, therefore, an appropriate regulation concerning the import and use of natural enemies is required to prevent these undesired side-effects (van Lenteren et al 2006a;Bale 2011;Ehlers 2011).…”

The prey range of Cryptolaemus montrouzieri was studied in the laboratory to investigate whether the mealybug destroyer can contribute to the suppression of other pest insects besides mealybugs and to assess its potential impact on non-mealybug populations as part of an environmental risk assessment for its use in biological control. Prey tested in these experiments were: tobacco aphid Myzus persicae nicotianae (Sulzer)(Hemiptera: Aphididae), pea aphid Acyrthosiphon pisum (Harris)(Hemiptera: Aphididae), tobacco whitefly Bemisia tabaci (Gennadius)(Hemiptera: Aleyrodidae), southern green stinkbug Nezara viridula (L.)(Hemiptera: Pentatomidae) eggs, western flower thrips Frankliniella occidentalis (Pergande)(Thysanoptera: Thripidae), two-spotted ladybird Adalia bipunctata (L.)(Coleoptera: Coccinellidae) eggs and eggs of the greater wax moth Galleria mellonella L. (Lepidoptera: Pyralidae). Larval survival was high to moderate when C. montrouzieri was provided with hemipteran prey and poor to zero when the ladybirds were provided with non-hemipteran prey. Females reared on M. persicae and A. pisum produced similar numbers of eggs as their counterparts fed the citrus mealybug Planococcus citri (Risso)(Hemiptera: Pseudococcidae), but fecundity was significantly lower when the ladybirds were reared on B. tabaci nymphs or on A. bipunctata eggs. Prey species that were found to be less suitable for immature development of C. montrouzieri could still be an adequate food source for reproduction and survival of adult ladybirds. For example, only 8 % of the predator larvae reached the adult stage when provided with A. bipunctata eggs, but females that had developed on eggs of the Mediterranean flour moth Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) and that were supplied with A. bipunctata eggs from adult emergence on, were only 35 % less fecund than females provided with mealybugs in their adult life. The results are discussed in relation to the development of a suitable methodology for prey/host range testing in the framework of an environmental risk assessment for arthropod natural enemies.

“…Because of the risks associated with the introduction of nonindigenous natural enemies, priority has been given in recent years to the use of indigenous species in the biological control of pests De Clercq et al, 2011). Three species of Orius (O. laevigatus (Fieber), O. majusculus (Reuter), and O. niger (Wolff)) are common in the Palearctic region, including Turkey (Péricart, 1972;Önder, 1982).…”

The photoperiodic sensitivity and storage of Orius majusculus (Reuter) from Antalya was investigated to obtain data for the optimization of its release. In the current study, it was not possible to induce a high (up to 100%) incidence of diapause unless all the nymphal instars and adults were successively exposed (i.e. full exposure) to a short day length (11.5 h) at constant temperatures of 18 and 26 °C, and fluctuating temperatures of 10/26 °C. Hence an intermittent exposure to long day lengths, even for short periods of time (only during instars IV-V or adult stage), would avoid a high incidence of diapause at 10/26 °C and 26 °C. The response of O. majusculus nymphal instars and adults to a short day length with a low incidence of diapause under fluctuating temperatures suggests that greenhouses, where such temperatures prevail, provide an environment that is conducive to diapause prevention. The release of adults is a better approach than the release of nymphs, since the adults and their nymphs, until the eclosion of new adults, are expected to respond to short day lengths with a low incidence of diapause in greenhouses. When nymphs are released, on the other hand, a high incidence of diapause would be inevitable. Increasing the constant temperature to 30 °C at full exposure did not prevent diapause and consequently did not change the incidence of diapause. Storage of diapausing O. majusculus adults was possible for 1 month with a higher survival rate and fecundity than in a study based on the storage of nondiapausing adults at a lower temperature.
