Insidious Flower Bug

The western flower thrips [Frankliniella occidentalis (Pergrande)] (Thysanoptera: Thripidae) is a major pest of greenhouse crops (Broadbent et al. 1987; van der Veire and Degheele 1992; Chambers et al. 1993). Chemical control of F. occidentalis is difficult because of its cryptic behaviour and widespread resistance to insecticides (Immaraju et al. 1992). The insidious flower bug, Orius insidiosus (Say), is widely promoted as an effective biological control agent for this pest (Chambers et al. 1993; van der Veire and Degheele 1992; Castane and Zalom 1994) and its use has increased steadily since their introduction in the late 1980s. When our project was initiated in 1989, O. insidiosus was a little known and largely unavailable biological control agent. Now there are several domestic and international commercial sources of Orius spp. and these predatory bugs have become a focus of research in Canada, the United States, and Europe. At first it was difficult and costly to maintain cultures of only 100 or 200 individuals but now we can rear 50000 — 100000 Orius per week for less than $0.03 (Canadian) each.

The Impact ◽  
Mite Mortality

Greenhouses contain a vast array of insect, mite, and disease pests primarily managed by applications of conventional and biorational pesticides including insecticides, miticides, and fungicides. However, biorational pesticides have a narrow range of pest activity. As a result, greenhouse producers tank mix to broaden application activity. Research has demonstrated that tank mixing can result in either synergistic or antagonistic interactions for targeted pests. However, the impact of tank mixing insecticides and fungicides on predatory mites, Neoseiulus cucumeris, used to manage western flower thrips, Franklinella occidentalis, is unknown. The objective of this research was to determine how mixtures of four different pesticides (Conserve, Avid, Cleary's, and Decree), alone and in all possible combinations affect predatory mite survival in a laboratory bioassay. Individual 2-day-old adult mites, isolated in a cell of a bioassay tray, were exposed to one of the 15 pesticide treatments, or a water control. Treatments were replicated 15 times. Trays were held in an environmental chamber and mite mortality was assessed after 24 hours. Mite mortality was differentially impacted by some pesticide treatments when compared with the water control. One pesticide mixture, Conserve + Cleary's, significantly reduced mite survival compared to other pesticide treatments or the water control. Up to 70% of the mites exposed to this treatment died. The combination of Conserve + Cleary's should be avoided as a tank mixture when the biological control agent, Neoseiulus cucumeris, is used to manage western flower thrips.
