Effectiveness ofOrius laevigatus(Hem.: Anthocoridae) for the control ofFrankliniella occidentalison cucumber and pepper in the UK

A simple mass-rearing method for predaceous Orius bugs in the laboratory

“…These results indicate that several hundred adults of both species can be obtained from a small cage such as a Petri dish. This is much better than the results of Chambers et al (1993) and potentially better than Schmidt et al (1995) on a per cage volume basis. The former reported that O. laevigatus was able to produce approximately 100-200 nymphs per week from a culture of up to 10 containers (15 cm diameter, 20 cm deep) feeding on Aphis gossypii Glover.…”

“…Although Orius bugs are successfully bred on eggs of the Mediterranean flour moth, Ephestia kuehniella Zeller, as an alternative food (Schmidt et al, 1995;Cocuzza et al, 1997;Montserrat et al, 2000;Yano et al, 2002), cannibalism in rearing cages under crowded conditions may be a problem (Chambers et al, 1993;Tommasini et al, 2002;Baniameri et al, 2005). To prevent such cannibalism, researchers have utilized folded paper tissue (Chambers et al, 1993), shredded paper (Arijs and DeClercq, 2001), a mesh sheet (Shimizu and Kawasaki, 2001) or unhulled rice grains (Yano, personal communication;Ito and Nakata, 1998) to expand the surface area in the rearing cage and as shelter materials for several Orius species.…”

For mass-rearing, however, very few studies have been done on the breeding capacity of rearing cages: therefore, this study focused on evaluating the plastic Petri dish as a mass-rearing cage using two Orius species, Orius strigicollis (Poppius) and O. laevigatus (Fieber) (Heteroptera: Anthocoridae).…”

Influence of Male Age and Diet on Reproductive Potential of Orius laevigatus (Hemiptera: Anthocoridae)

“…Orius laevigatus (Fieber) (Hemiptera: Anthocoridae) is a biological control agent of thrips, spider mites, aphids, and whiteßies and has been commercially available since the 1990s (Chambers et al 1993, Montserrat et al 2000, Venzon et al 2002. Commercial mass production of this predator is generally done using eggs of the Mediterranean ßour moth, Anagasta kuehniella (Zeller), as food and plant materials such as bean pods as oviposition substrates.…”

Enhancing pest management in sweet pepper by the exploitation of zoophytophagy

“…It can also be effective against B. tabaci (Chambers et al, 1993;Dissevelt et al, 1995;Frescata and Mexia, 1996;Abu-Awad, 2007, 2008). In addition, O. laevigatus can consume other arthropod pests such as aphids and mites (Alvarado et al, 1997;Venzon et al, 2002).…”
