Pesticide and Other Controls:

Ideal Environment:

Orius works best in warm and humid environments, typical greenhouse temperature of 18-20°C and a humidity of over 60% work very well. Orius can be successfully implemented in a variety of different environments such as orchards & vineyards, nursery, greenhouse, aquaponics, hydroponics, container plants, outdoor fields, and much more. They are especially effective in pollen bearing crops (sweet pepper, strawberry, cucumber) since they feed on pollen and can establish their population more easily when other food supply is short.

Orius is adversely affected by the use of pesticides, particularly those with long residual actions (pyrethroids, organophosphates, and neonicotinoids). Residues left behind from the spray can last for months in foliage or plant tissues and can impact survival rates of Orius. We suggest checking side-effect charts carefully and avoid spraying any chemicals after the release of Orius unless they are known to be safe. If you have more question please contact us for a free consultation by one of our Ph.D. entomologist. We would love to help.

Release rate varies considerably depending on the crop, infestation level and season of the year. This is just a general release rate, please contact us here to create an IPM program that works for you.

Note: If not using immediately, keep in a cool (42-50°F) dark place out of direct sunlight.

  • If extra pollen is being added to crops as a means of food for Orius be aware that the western flower thrips also uses such foods as a source of nutrition. Thus flower thrips should be monitored to ensure they are not benefiting from this practice

  • Orius is attracted to yellow sticky traps, if they are being used in your crops, we suggest placing 1 for every 100 plants or more.

  • Orius is a diapausing insect and becomes inactive during shorter cooler days, thus we don't recommend using it during winter unless additional lighting is being used.

Orius is black with cream markings on its body and can be easily seen by the naked eye. There are several ways you can detect its establishment in your crops. We suggest tapping plants, especially flowers, over a piece of white paper or tray to view the number of larvae and adults in the crops. Another great indicator is to monitor nymph population in banker plant systems. You may also monitor the thrips levels using sticky traps to see how well the Orius is working.

Product Detail

Orius Insidiosus (Minute Pirate Bug) are a species of general predatory bug that feeds on many small, soft-bodied insects. They are especially aggressive towards thrips and can control all stages of it. Adults can consume as many as 12 pests a day and will continue to kill about 40 more in the process. In addition, when there is no prey available it can also feed on pollen, which allows it to establish a population in pollen rich crops. Orius is also able to reproduce quickly since it has a short life cycle of 3-4 weeks (depending on the temperature and humidity) which makes them very effective at controlling serious infestations quickly. It is a very active flyer and can provide coverage throughout the crop. Note: Orius is a diapausing insect and cannot be used year-round. We sell Orius in two bottle sizes, 500 and 1000. It is mixed with vermiculite and buckwheat husk to provide some volume and make application easier and more even.
