Biological Control in Plant Protection

Prevention of Whitefly Entry from a Greenhouse Entrance by Furnishing an Airflow-Oriented Pre-Entrance Room Guarded with Electric Field Screens

“…The photo-attracted movement of whiteflies (Helyer et al, 2004) was the key to provide a splendid resolution to this problem. For this approach, we tested the attracted movement of whiteflies to the yellow-boarded DD-screen.…”

Ecology and Role of the Rove Beetle, <i>Dalotia coriaria</i>, and Insidious Flower Bug, <i>Orius insidiosus</i>, in Greenhouse Biological Control Programs

“…Adults begin searching for food after emerging from pupae, and are mobile, flying long distances although they tend to spend most of their time in growing media. Larvae are white during the early instars whereas the later instars are yellow-brown [24]. The life history of D. coriaria has been studied under laboratory conditions with development time from egg to adult taking 17 days [25] although development time varies depending on temperature.…”

“…Adults and larvae reside in the growing medium and feed on fungus gnat larvae [24] [28] [29] and western flower thrips pupae (Yinping Li, unpublished data). Rove beetle adults prefer fungus gnat, Bradysia sp.…”

Life History Characteristics of the Rove Beetle,Dalotia coriaria(Coleoptera: Staphylinidae) under Laboratory Conditions

“…Duration of the life cycle from egg to adult was 13, and 11 to 12 days at 27 and 32uC, respectively (Miller and Williams, 1983). In addition, D. coriaria development from egg to adult was 21 to 22 days at 25uC (Carney et al, 2002;Helyer et al, 2003). Adult longevity is approximately 21 days while the number of individuals (offspring) in the F 1 generation is 15 rove beetles per female, although this may vary (Carney et al, 2002).…”

“…larvae, and adults may also feed on shore flies (Scatella spp.) and thrips nymphs and pupae; all of which are major insect pests of greenhouse-grown crops (Carney et al, 2002;Helyer et al, 2003;Meihls and Hibbard, 2009).…”
