Amblyseius swirskii - is a predatory mite useful in the control of the whitefly predominantly, and with some impact to spider mites as a noted side benefit. Benefits include rapid development and a wide-ranging appetite. They do not undergo diapause, due to short day-lengths or low temperatures, meaning they can be used late into the fall and into the winter indoors. Bear in mind, though, that at around 59° A. swirskii will become inactive.
Optimum performance: 77-82° F, 70% a relative microclimate humidity
Release rates: 2-5/sq ft, bi-weekly, as needed
Biological Pest Control Agents
Biocontrols are an effective tool to growers in just about any situation. Bear in mind that when using biocontrols, a new set
of rules must be followed:
1. Growers must reduce the amounts of pesticides used, and in most cases, either substitute what’s on hand or, better yet, simply discontinue the use of pesticides entirely. (The outcome of this is typically a major reduction in applicator labor.)
2. Multiple releases of biocontrols are necessary in nearly every case, like most sprays, and should be thought of as a part of an overall program or strategy.
3. All live biocontrols are shipped next day air, from the grower, therefore freight costs can be high. Detailed short-term storage, handling and release instructions are included with every order.
Orders must be placed by Wednesday 12pm CST to get shipment by the following week.
