Green lacewings are aggressive nocturnal aphid predators. They come in three forms: eggs, larvae, and adults. The eggs are useful when you’re in no great hurry to get rid of aphids and other pests. The larvae are useful for quick cleanup, and the adults, being nomadic like Aphidoletes aphidimyza are useful in tree applications. The larvae are the only predatory form of the green lacewing, but they’re very opportunistic. These predators may eat outside of their diet to enjoy other soft-bodied pests: scale insect immature stages, (including long-tailed) and mealybug species, whiteflies, and others, especially certain insect eggs.Optimum performance:
67-89° F, 30% relative humidity or greaterRelease rates:
Rates shown are for larvae. If you’re using eggs, multiply the calculated rate by five (5). If employing adults, divide the calculated rate by four (4).
Biological Pest Control Agents
|Preventative||1-3/10 sq ft, monthly, as needed|
|Low||2-5/10 sq ft bi-weekly, 2-3 times|
|Medium||4-8/10 sq ft, weekly, 2-4 times|
|High||1/sq ft, bi-wkly, 3-5 times|
|Maintenance||1-2/10 sq ft., tri-weekly, indefinitely|
|Garden||60-90% of rates listed|
|Acre+||20-50% of rates listed|
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. Note to growers:
