The life cycle is temperature dependent, about 21 days with
            temperatures around 70° F. Some BCAs enter into diapause   Special on
            as the days become shorter and the temperatures cool.
            Diapause is similar to hibernation, a phase where the insect
            or mite is not active until warmer temperatures return. Rove   Botanigard
            beetles do not enter into diapause. When you tally up the
            attributes of the small but mighty rove beetle, it's easy to
            see why they're good partners in year-round IPM programs.
            Combined  with other biological  control agents (BCAs)  that
            feed on other life stages, rove beetles provide an important
            component in breaking up the life cycle of important pests
            such as thrips. They can also be valuable components of
            a conventional pesticide program so long  as compatible
            pesticides are emphasized. (GGSPro can  help you with
            pesticide selection.)                                             20%}
            In  a  moist  environment, rove  beetles  can  reproduce
            successfully on a wide variety of soilless media such as peat
            moss, pine bark, rockwool and coir. This allows growers to
            maintain a high level of rove beetles at a relatively low cost.
            For years, growers have placed rove beetles in small piles of
            approximate 25 adult beetles with other life stages present
            spread sporadically throughout the greenhouse on the floors,
            along baseboards where moist soil or algae are present. The
            high mobility of this predator makes the exact placement of
            the breeding colonies less important. For concrete floors and    {Save
            other dryer environments, growers can place piles on the
            surface of soilless media in containers that are kept moist
            under the benches.

            A recent innovation from Bioline Agrosciences has resulted
            in a breeding station to further automate production of large
            quantities of rove beetles, improving reliability while reducing
            the cost further. They refer to the system as a breeder bucket.
            The system begins with a specifically designed bucket that is
            filled with media selected for this purpose. Once the media is
            uniformly moistened, a 1 liter (500 beetles) tube of the rove
            beetles is added along with 2 teaspoons of the provided
            food. This mixture is tumbled within the bucket to ensure
            good uniformity of the various life stages of rove beetle and
            the food. The bucket is placed within the greenhouse out
            of direct sunlight. There is a weekly recipe for the amount
            of water and food that is
            added, and the bucket                                                         BotaniGard 22 WP
