The larvae and adult Delphastus catalinae (Delphastus pusillus) are ravenous ladybird beetles. Each bug can consume up to 10,000 whitefly eggs and 700 whitefly larvae in their short, 25 day, life time. These small beetles will also feed on spider mites and aphids if their preferred prey is scarce. Through these bugs can eat a large volume of prey they cannot control outbreaks alone and should be paired with E. formosa for best results.
Dosage - The information given here is a general guideline. Release rates can be affected by the stage/size of the cannabis plant, climate conditions, and level of infestation.
For small infestations release 0.5 beetles per ft² every second week for at least three applications. For larger infestations release 1-2 beetles per ft² every second week for at least four applications. If there is a heavy infestation, release 10 beetles per plant, per vertical foot, weekly for at least three weeks or until biological balance has been achieved. For hot spots, release 30-100 beetles per hotspot, weekly for at least three weeks, or until biological balance is achieved.
You will receive your D. catalinae in a 30ml plastic tube with filter paper. Evenly distribute them through out your crop concentrating on any hotspots. These beetles should be distributed during the coolest parts of the day. We recommend using beneficial distribution boxes.
We recommend immediate release of the D. catalinae.
If immediate release in not possible you may store D. catalinae at 8-10°c for 1-2 days. Do not refrigerate
