Cryptolaemus montrouzieri a.k.a. Crypts or The Mealy Bug Destroyer Bar none, this beetle species is the number one predator used to control most mealybug species. The only critical requirement to use this opportunistic beetle, is to ensure the pests’ cottony egg masses are present, as this is where Crypts lay their eggs. Must control ants if present.
Optimum performance: 64-91° F, 70% or greater relative humidity
Release rates: Light - 2-4/10 sq ft; Heavy - 10-12/10 sq ft; Orchards - 1,000-2,000/acre
NOTE: For more mealybug control options, also see Chrysoperla rufilabris under Aphid Controls.
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.
