Effective use of Chrysoperla in Commercial Cannabis cultivation:

Rates with Chrysoperla in cannabis seem to vary a little from what the traditional, registered rates would indicate. Instead of treating in meters, and as a row crop, we recommend that each plant have direct attention paid to them, for optimal results. The climate fluctuation and temperature and humidity variations, along with the plant’s rapid growth pattern, necessity to ensure proper air movement, and hairiness/stickiness of the plant all combine to make cannabis a complex and difficult crop to treat.

Description

Chrysoperla adults search out new pest infestations to become sites for egg laying, and the larvae begin searching for prey immediately after hatching. The larvae are voracious natural predators that easily distribute to follow movement of pest insects on plants. The large hollow jaws of the larvae penetrate through the cuticle of the pest insect, injecting a digestive enzyme that liquefies the internal body, allowing it to be sucked out through the mandibles. The larvae will target a wide variety of aphid species and can consume more than 200 aphids in a day, making them an excellent option for rapid knockdown pest control. 

Chrysoperla are generally not suitable for preventative pest control, as the larvae need plentiful prey to complete their life cycle.

Adult Chrysoperla are 11 to 13 mm in length, featuring a long slender body and wings with many small veins, resembling a lace pattern. The eggs are whitish green and oval, deposited at the end of a long erect stalk about 1 cm in length, and the larvae are long (2-10mm) with pronounced forward-projecting jaws. Mature larvae will pupate a hairy white cocoon attached to plant leaves. 

Available in 2,500; Larvae, bag

Life Cycle

Adult Chrysoperla females lay single eggs, whitish green and oval, deposited at the end of a long erect stalk about 1 cm in length. There may be 1-10 egg stalks in a lone along the underside of a leaf. When hatched, the larvae are long with pronounced forward-projecting jaws, and are usually found where prey is plentiful. Developing larval stages are between 1-10mm in length. Mature larvae will pupate a hairy white cocoon attached to plant leaves. Once emerged, adult Chrysoperla feed on nectar and pollen, and do not contribute to pest control.
