Product Description

CHRYSOforce™ R is the green lacewing, Chrysoperla rufilabris — a voracious generalist whose larvae eat just about any soft-bodied pest they can catch, and they are always hungry. This format ships as pre-fed larvae in a 6×8 hex cell rearing frame: each larva develops in its own cell, separated so they arrive healthy and ready to release. Use it across ornamentals, hemp/cannabis, vegetables, soft fruits, and tree nurseries, in greenhouses, indoor facilities, fields, gardens, and orchards. Note: green lacewing does not control root aphids.

What it targets

The larvae feed on:

Many aphid species
Many mealybug species
Spider mites
Many thrips species
Whiteflies (eggs/juveniles)
Eggs of many pest species

Crops it supports

Ornamentals, hemp/cannabis, vegetables, soft fruits, and tree nurseries — in greenhouses, indoor facilities, fields, gardens, and orchards.

How the green lacewing controls pests

The larvae seek out prey and suck the life out of them, consuming up to 50 aphids a day, and they are capable of attacking large prey. Females can lay 400-plus eggs near pest hot spots. Green lacewing stays active in low light and cooler temperatures, which makes it a flexible predator across many crops.

Release Instructions

Release timing: The pre-fed larvae are still developing inside individual cells of the rearing frame. Release them the same day received (no later than the following day) unless your packing slip says otherwise. Hold the frame up to the light and you can see the larvae in their cells.

Release method: Peel back one side of the organdy material an inch at a time and “knock” or tap the larvae out onto the target area, then peel off the organdy on the other side. You can lay the frame next to a plant so any remaining larvae crawl out onto the crop.

Storage: Do not cold store the larvae. Release them the same day they are received.

Monitoring: Larvae are small, fast, and hard to find in the crop — the best time to look is in the evening. The clearest sign the lacewings are working is a drop in pests a few days after release.

Advisories: If ants are present, control them before releasing — ants feed on aphid honeydew and will protect aphids from predators. Adult lacewings need pollen, nectar, or other suitable food to breed; Wheast™ can be given to adults as a supplement.
